trait Configuration extends AnyRef
Trait providing methods and classes used to configure property checks provided by the the forAll methods of trait GeneratorDrivenPropertyChecks (for ScalaTest-style property checks) and the check methods of trait Checkers (for ScalaCheck-style property checks).
trait TableDrivenPropertyChecks extends Whenever with Tables
Trait containing methods that faciliate property checks against tables of data.
Trait containing methods that faciliate property checks against tables of data.
This trait contains one exists, forAll, and forEvery method for each TableForN class, TableFor1 through TableFor22, which allow properties to be checked against the rows of a table. It also contains a wherever method that can be used to indicate a property need only hold whenever some condition is true.
For an example of trait TableDrivenPropertyChecks in action, imagine you want to test this Fraction class:
```
class Fraction(n: Int, d: Int) {

  require(d != 0)
  require(d != Integer.MIN_VALUE)
  require(n != Integer.MIN_VALUE)

  val numer = if (d < 0) -1 * n else n
  val denom = d.abs

  override def toString = numer + " / " + denom
}
```
TableDrivenPropertyChecks allows you to create tables with between 1 and 22 columns and any number of rows. You create a table by passing tuples to one of the factory methods of object Table. Each tuple must have the same arity (number of members). The first tuple you pass must all be strings, because it define names for the columns. Subsequent tuples define the data. After the initial tuple that contains string column names, all tuples must have the same type. For example, if the first tuple after the column names contains two Ints, all subsequent tuples must contain two Int (i.e., have type Tuple2[Int, Int]).
To test the behavior of Fraction, you could create a table of numerators and denominators to pass to the constructor of the Fraction class using one of the apply factory methods declared in Table, like this:
```
import org.scalatest.prop.TableDrivenPropertyChecks._

val fractions =
  Table(
    ("n", "d"),  // First tuple defines column names
    (  1,   2),  // Subsequent tuples define the data
    ( -1,   2),
    (  1,  -2),
    ( -1,  -2),
    (  3,   1),
    ( -3,   1),
    ( -3,   0),
    (  3,  -1),
    (  3,  Integer.MIN_VALUE),
    (Integer.MIN_VALUE, 3),
    ( -3,  -1)
  )
```
You could then check a property against each row of the table using a forAll method, like this:
```
import org.scalatest.Matchers._

forAll (fractions) { (n: Int, d: Int) =>

  whenever (d != 0 && d != Integer.MIN_VALUE
      && n != Integer.MIN_VALUE) {

    val f = new Fraction(n, d)

    if (n < 0 && d < 0 || n > 0 && d > 0)
      f.numer should be > 0
    else if (n != 0)
      f.numer should be < 0
    else
      f.numer should be === 0

    f.denom should be > 0
  }
}
```
Trait TableDrivenPropertyChecks provides 22 overloaded exists, forAll, and forEvery methods that allow you to check properties using the data provided by a table. Each exists, forAll, and forEvery method takes two parameter lists. The first parameter list is a table. The second parameter list is a function whose argument types and number matches that of the tuples in the table. For example, if the tuples in the table supplied to forAll each contain an Int, a String, and a List[Char], then the function supplied to forAll must take 3 parameters, an Int, a String, and a List[Char]. The forAll method will pass each row of data to the function, and generate a TableDrivenPropertyCheckFailedException if the function completes abruptly for any row of data with any exception that would normally cause a test to fail in ScalaTest other than DiscardedEvaluationException. A DiscardedEvaluationException, which is thrown by the whenever method (also defined in this trait) to indicate a condition required by the property function is not met by a row of passed data, will simply cause forAll to skip that row of data.
The full list of table methods are:
- exists - succeeds if the assertion holds true for at least one element
- forAll - succeeds if the assertion holds true for every element
- forEvery - same as forAll, but lists all failing elements if it fails (whereas forAll just reports the first failing element) and throws TestFailedException with the first failed check as the cause.
Testing stateful functions
One way to use a table with one column is to test subsequent return values of a stateful function. Imagine, for example, you had an object named FiboGen whose next method returned the next fibonacci number, where next means the next number in the series following the number previously returned by next. So the first time next was called, it would return 0. The next time it was called it would return 1. Then 1. Then 2. Then 3, and so on. FiboGen would need to maintain state, because it has to remember where it is in the series. In such a situation, you could create a TableFor1 (a table with one column, which you could alternatively think of as one row), in which each row represents the next value you expect.
```
val first14FiboNums =
  Table("n", 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233)
```
Then in your forAll simply call the function and compare it with the expected return value, like this:
```
forAll (first14FiboNums) { n =>
  FiboGen.next should equal (n)
}
```
Testing mutable objects
If you need to test a mutable object, one way you can use tables is to specify state transitions in a table. For example, imagine you wanted to test this mutable Counter class:
```
class Counter {
  private var c = 0
  def reset() { c = 0 }
  def click() { c += 1 }
  def enter(n: Int) { c = n }
  def count = c
}
```
A Counter keeps track of how many times its click method is called. The count starts out at zero and increments with each click invocation. You can also set the count to a specific value by calling enter and passing the value in. And the reset method returns the count back to zero. You could define the actions that initiate state transitions with case classes, like this:
```
abstract class Action
case object Start extends Action
case object Click extends Action
case class Enter(n: Int) extends Action
```
Given these actions, you could define a state-transition table like this:
```
val stateTransitions =
  Table(
    ("action", "expectedCount"),
    (Start,    0),
    (Click,    1),
    (Click,    2),
    (Click,    3),
    (Enter(5), 5),
    (Click,    6),
    (Enter(1), 1),
    (Click,    2),
    (Click,    3)
  )
```
To use this in a test, simply do a pattern match inside the function you pass to forAll. Make a pattern for each action, and have the body perform that action when there's a match. Then check that the actual value equals the expected value:
```
val counter = new Counter
forAll (stateTransitions) { (action, expectedCount) =>
  action match {
    case Start => counter.reset()
    case Click => counter.click()
    case Enter(n) => counter.enter(n)
  }
  counter.count should equal (expectedCount)
}
```
Testing invalid argument combinations
A table-driven property check can also be helpful to ensure that the proper exception is thrown when invalid data is passed to a method or constructor. For example, the Fraction constructor shown above should throw IllegalArgumentException if Integer.MIN_VALUE is passed for either the numerator or denominator, or zero is passed for the denominator. This yields the following five combinations of invalid data:

n d

Integer.MIN_VALUE Integer.MIN_VALUE

a valid value Integer.MIN_VALUE

Integer.MIN_VALUE a valid value

Integer.MIN_VALUE zero

a valid value zero

You can express these combinations in a table:
```
val invalidCombos =
  Table(
    ("n",               "d"),
    (Integer.MIN_VALUE, Integer.MIN_VALUE),
    (1,                 Integer.MIN_VALUE),
    (Integer.MIN_VALUE, 1),
    (Integer.MIN_VALUE, 0),
    (1,                 0)
  )
```
Given this table, you could check that all invalid combinations produce IllegalArgumentException, like this:
```
forAll (invalidCombos) { (n: Int, d: Int) =>
  evaluating {
    new Fraction(n, d)
  } should produce [IllegalArgumentException]
}
```
class TableFor1[A] extends IndexedSeq[A] with IndexedSeqLike[A, TableFor1[A]]
A table with 1 column.
A table with 1 column.
For an overview of using tables, see the documentation for trait TableDrivenPropertyChecks.
This table is a sequence of objects, where each object represents one row of the (one-column) table. This table also carries with it a heading tuple that gives a string name to the lone column of the table.
A handy way to create a TableFor1 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:
```
val examples =
  Table(
    "a",
      0,
      1,
      2,
      3,
      4,
      5,
      6,
      7,
      8,
      9
  )
```
Because you supplied a list of non-tuple objects, the type you'll get back will be a TableFor1.
The table provides an apply method that takes a function with a parameter list that matches the type of the objects contained in this table. The apply method will invoke the function with the object in each row passed as the lone argument, in ascending order by index. (I.e., the zeroth object is checked first, then the object with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor1 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor1, passing in the property check function. Here's an example:
```
forAll (examples) { (a) =>
  a should equal (a * 1)
}
```
Because TableFor1 is a Seq[(A)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.
One other way to use a TableFor1 is to test subsequent return values of a stateful function. Imagine, for example, you had an object named FiboGen whose next method returned the next fibonacci number, where next means the next number in the series following the number previously returned by next. So the first time next was called, it would return 0. The next time it was called it would return 1. Then 1. Then 2. Then 3, and so on. FiboGen would need to be stateful, because it has to remember where it is in the series. In such a situation, you could create a TableFor1 (a table with one column, which you could alternatively think of as one row), in which each row represents the next value you expect.
```
val first14FiboNums =
  Table("n", 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233)
```
Then in your forAll simply call the function and compare it with the expected return value, like this:
```
forAll (first14FiboNums) { n =>
  FiboGen.next should equal (n)
}
```
class TableFor10[A, B, C, D, E, F, G, H, I, J] extends IndexedSeq[(A, B, C, D, E, F, G, H, I, J)] with IndexedSeqLike[(A, B, C, D, E, F, G, H, I, J), TableFor10[A, B, C, D, E, F, G, H, I, J]]
A table with 10 columns.
A table with 10 columns.
For an introduction to using tables, see the documentation for trait TableDrivenPropertyChecks.
This table is a sequence of Tuple10 objects, where each tuple represents one row of the table. The first element of each tuple comprise the first column of the table, the second element of each tuple comprise the second column, and so on. This table also carries with it a heading tuple that gives string names to the columns of the table.
A handy way to create a TableFor10 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:
```
val examples =
  Table(
    ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j"),
 *     (  0,   0,   0,   0,   0,   0,   0,   0,   0,   0),
    (  1,   1,   1,   1,   1,   1,   1,   1,   1,   1),
    (  2,   2,   2,   2,   2,   2,   2,   2,   2,   2),
    (  3,   3,   3,   3,   3,   3,   3,   3,   3,   3),
    (  4,   4,   4,   4,   4,   4,   4,   4,   4,   4),
    (  5,   5,   5,   5,   5,   5,   5,   5,   5,   5),
    (  6,   6,   6,   6,   6,   6,   6,   6,   6,   6),
    (  7,   7,   7,   7,   7,   7,   7,   7,   7,   7),
    (  8,   8,   8,   8,   8,   8,   8,   8,   8,   8),
    (  9,   9,   9,   9,   9,   9,   9,   9,   9,   9)
  )
```
Because you supplied 10 members in each tuple, the type you'll get back will be a TableFor10.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor10 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor10, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j) =>
  a + b + c + d + e + f + g + h + i + j should equal (a * 10)
}
```
Because TableFor10 is a Seq[(A, B, C, D, E, F, G, H, I, J)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.
class TableFor11[A, B, C, D, E, F, G, H, I, J, K] extends IndexedSeq[(A, B, C, D, E, F, G, H, I, J, K)] with IndexedSeqLike[(A, B, C, D, E, F, G, H, I, J, K), TableFor11[A, B, C, D, E, F, G, H, I, J, K]]

This table is a sequence of Tuple11 objects, where each tuple represents one row of the table. The first element of each tuple comprise the first column of the table, the second element of each tuple comprise the second column, and so on. This table also carries with it a heading tuple that gives string names to the columns of the table.
A handy way to create a TableFor11 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:

    (  1,   1,   1,   1,   1,   1,   1,   1,   1,   1,   1),

    (  9,   9,   9,   9,   9,   9,   9,   9,   9,   9,   9)
  )
```
Because you supplied 11 members in each tuple, the type you'll get back will be a TableFor11.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor11 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor11, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j, k) =>
  a + b + c + d + e + f + g + h + i + j + k should equal (a * 11)
}
```
Because TableFor11 is a Seq[(A, B, C, D, E, F, G, H, I, J, K)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.
class TableFor12[A, B, C, D, E, F, G, H, I, J, K, L] extends IndexedSeq[(A, B, C, D, E, F, G, H, I, J, K, L)] with IndexedSeqLike[(A, B, C, D, E, F, G, H, I, J, K, L), TableFor12[A, B, C, D, E, F, G, H, I, J, K, L]]
A table with 12 columns.
A table with 12 columns.
For an introduction to using tables, see the documentation for trait TableDrivenPropertyChecks.
This table is a sequence of Tuple12 objects, where each tuple represents one row of the table. The first element of each tuple comprise the first column of the table, the second element of each tuple comprise the second column, and so on. This table also carries with it a heading tuple that gives string names to the columns of the table.
A handy way to create a TableFor12 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:
```
val examples =
  Table(
    ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l"),
 *     (  0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0),
    (  1,   1,   1,   1,   1,   1,   1,   1,   1,   1,   1,   1),
    (  2,   2,   2,   2,   2,   2,   2,   2,   2,   2,   2,   2),
    (  3,   3,   3,   3,   3,   3,   3,   3,   3,   3,   3,   3),
    (  4,   4,   4,   4,   4,   4,   4,   4,   4,   4,   4,   4),
    (  5,   5,   5,   5,   5,   5,   5,   5,   5,   5,   5,   5),
    (  6,   6,   6,   6,   6,   6,   6,   6,   6,   6,   6,   6),
    (  7,   7,   7,   7,   7,   7,   7,   7,   7,   7,   7,   7),
    (  8,   8,   8,   8,   8,   8,   8,   8,   8,   8,   8,   8),
    (  9,   9,   9,   9,   9,   9,   9,   9,   9,   9,   9,   9)
  )
```
Because you supplied 12 members in each tuple, the type you'll get back will be a TableFor12.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor12 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor12, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j, k, l) =>
  a + b + c + d + e + f + g + h + i + j + k + l should equal (a * 12)
}
```
Because TableFor12 is a Seq[(A, B, C, D, E, F, G, H, I, J, K, L)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.

A table with 13 columns.
For an introduction to using tables, see the documentation for trait TableDrivenPropertyChecks.
This table is a sequence of Tuple13 objects, where each tuple represents one row of the table. The first element of each tuple comprise the first column of the table, the second element of each tuple comprise the second column, and so on. This table also carries with it a heading tuple that gives string names to the columns of the table.
A handy way to create a TableFor13 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:
```
val examples =
  Table(
    ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m"),
 *     (  0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0),
    (  1,   1,   1,   1,   1,   1,   1,   1,   1,   1,   1,   1,   1),
    (  2,   2,   2,   2,   2,   2,   2,   2,   2,   2,   2,   2,   2),
    (  3,   3,   3,   3,   3,   3,   3,   3,   3,   3,   3,   3,   3),
    (  4,   4,   4,   4,   4,   4,   4,   4,   4,   4,   4,   4,   4),

  )
```
Because you supplied 13 members in each tuple, the type you'll get back will be a TableFor13.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor13 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor13, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j, k, l, m) =>
  a + b + c + d + e + f + g + h + i + j + k + l + m should equal (a * 13)
}
```
Because TableFor13 is a Seq[(A, B, C, D, E, F, G, H, I, J, K, L, M)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.

Because you supplied 17 members in each tuple, the type you'll get back will be a TableFor17.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor17 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor17, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q) =>
  a + b + c + d + e + f + g + h + i + j + k + l + m + n + o + p + q should equal (a * 17)
}
```
Because TableFor17 is a Seq[(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.

Because you supplied 20 members in each tuple, the type you'll get back will be a TableFor20.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor20 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor20, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t) =>
  a + b + c + d + e + f + g + h + i + j + k + l + m + n + o + p + q + r + s + t should equal (a * 20)
}
```
Because TableFor20 is a Seq[(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.

For an introduction to using tables, see the documentation for trait TableDrivenPropertyChecks.
This table is a sequence of Tuple21 objects, where each tuple represents one row of the table. The first element of each tuple comprise the first column of the table, the second element of each tuple comprise the second column, and so on. This table also carries with it a heading tuple that gives string names to the columns of the table.
A handy way to create a TableFor21 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:

Because you supplied 21 members in each tuple, the type you'll get back will be a TableFor21.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor21 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor21, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u) =>
  a + b + c + d + e + f + g + h + i + j + k + l + m + n + o + p + q + r + s + t + u should equal (a * 21)
}
```
Because TableFor21 is a Seq[(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.

Because you supplied 22 members in each tuple, the type you'll get back will be a TableFor22.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table.

It invokes apply on the TableFor22, passing in the property check function. Here's an example:

}
```
Because TableFor22 is a Seq[(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:

Because you supplied 4 members in each tuple, the type you'll get back will be a TableFor4.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index.

```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded.

Because you supplied 5 members in each tuple, the type you'll get back will be a TableFor5.
The table provides an apply method that takes a function with a parameter list that matches the types and arity of the tuples contained in this table. The apply method will invoke the function with the members of each row tuple passed as arguments, in ascending order by index. (I.e., the zeroth tuple is checked first, then the tuple with index 1, then index 2, and so on until all the rows have been checked (or until a failure occurs). The function represents a property of the code under test that should succeed for every row of the table. If the function returns normally, that indicates the property check succeeded for that row. If the function completes abruptly with an exception, that indicates the property check failed and the apply method will complete abruptly with a TableDrivenPropertyCheckFailedException that wraps the exception thrown by the supplied property function.
The usual way you'd invoke the apply method that checks a property is via a forAll method provided by trait TableDrivenPropertyChecks. The forAll method takes a TableFor5 as its first argument, then in a curried argument list takes the property check function. It invokes apply on the TableFor5, passing in the property check function. Here's an example:
```
forAll (examples) { (a, b, c, d, e) =>
  a + b + c + d + e should equal (a * 5)
}
```
Because TableFor5 is a Seq[(A, B, C, D, E)], you can use it as a Seq. For example, here's how you could get a sequence of Outcomes for each row of the table, indicating whether a property check succeeded or failed on each row of the table:
```
for (row <- examples) yield {
  outcomeOf { row._1 should not equal (7) }
}
```
Note: the outcomeOf method, contained in the OutcomeOf trait, will execute the supplied code (a by-name parameter) and transform it to an Outcome. If no exception is thrown by the code, outcomeOf will result in a Succeeded, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail, outcomeOf will result in in a Failed instance containing that exception. For example, the previous for expression would give you:
```
Vector(Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded, Succeeded,
    Failed(org.scalatest.TestFailedException: 7 equaled 7), Succeeded, Succeeded)
```
This shows that all the property checks succeeded, except for the one at index 7.

A table with 6 columns.
For an introduction to using tables, see the documentation for trait TableDrivenPropertyChecks.
This table is a sequence of Tuple6 objects, where each tuple represents one row of the table. The first element of each tuple comprise the first column of the table, the second element of each tuple comprise the second column, and so on. This table also carries with it a heading tuple that gives string names to the columns of the table.
A handy way to create a TableFor6 is via an apply factory method in the Table singleton object provided by the Tables trait. Here's an example:
```
val examples =
  Table(
    ("a", "b", "c", "d", "e", "f"),
 *     (  0,   0,   0,   0,   0,   0),
