trait ScalaCheckPropertyChecks extends TableDrivenPropertyChecks with ScalaCheckDrivenPropertyChecks

Trait that facilitates property checks on data supplied by tables and generators.

This trait extends both TableDrivenPropertyChecks and GeneratorDrivenPropertyChecks. Thus by mixing in this trait you can perform property checks on data supplied either by tables or generators. For the details of table- and generator-driven property checks, see the documentation for each by following the links above.

For a quick example of using both table and generator-driven property checks in the same suite of tests, however, 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
}

If you mix in PropertyChecks, you could use a generator-driven property check to test that the passed values for numerator and denominator are properly normalized, like this:

forAll { (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 shouldEqual 0

    f.denom should be > 0
  }
}

And you could use a table-driven property check to test that all combinations of invalid values passed to the Fraction constructor produce the expected IllegalArgumentException, like this:

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)
  )

forAll (invalidCombos) { (n: Int, d: Int) =>
  an [IllegalArgumentException] should be thrownBy {
    new Fraction(n, d)
  }
}

class ConfiguredPropertyCheck extends AnyRef
Performs a configured property checks by applying property check functions passed to its apply methods to arguments supplied by implicitly passed generators, modifying the values in the PropertyGenConfig object passed implicitly to its apply methods with parameter values passed to its constructor.
Performs a configured property checks by applying property check functions passed to its apply methods to arguments supplied by implicitly passed generators, modifying the values in the PropertyGenConfig object passed implicitly to its apply methods with parameter values passed to its constructor.
Instances of this class are returned by trait ScalaCheckDrivenPropertyChecks forAll method that accepts a variable length argument list of PropertyCheckConfigParam objects. Thus it is used with functions of all six arities. Here are some examples:
```
forAll (minSize(1), maxSize(10)) { (a: String) =>
  a.length should equal ((a).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String) =>
  a.length + b.length should equal ((a + b).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String) =>
  a.length + b.length + c.length should equal ((a + b + c).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String) =>
  a.length + b.length + c.length + d.length should equal ((a + b + c + d).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String, e: String) =>
  a.length + b.length + c.length + d.length + e.length should equal ((a + b + c + d + e).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String, e: String, f: String) =>
  a.length + b.length + c.length + d.length + e.length + f.length should equal ((a + b + c + d + e + f).length)
}
```
In the first example above, the ConfiguredPropertyCheck object is returned by:
```
forAll (minSize(1), maxSize(10))
```
The code that follows is an invocation of one of the ConfiguredPropertyCheck apply methods:
```
{ (a: String) =>
  a.length should equal ((a).length)
}
```

case class MaxDiscarded(value: Int) extends PropertyCheckConfigParam with Product with Serializable
A PropertyCheckConfigParam that specifies the maximum number of discarded property evaluations allowed during property evaluation.
A PropertyCheckConfigParam that specifies the maximum number of discarded property evaluations allowed during property evaluation.
In GeneratorDrivenPropertyChecks, a property evaluation is discarded if it throws DiscardedEvaluationException, which is produce by whenever clause that evaluates to false. For example, consider this ScalaTest property check:
```
// forAll defined in GeneratorDrivenPropertyChecks
forAll { (n: Int) =>
  whenever (n > 0) {
    doubleIt(n) should equal (n * 2)
  }
}
```
In the above code, whenever a non-positive n is passed, the property function will complete abruptly with DiscardedEvaluationException.
Similarly, in Checkers, a property evaluation is discarded if the expression to the left of ScalaCheck's ==> operator is false. Here's an example:
```
// forAll defined in Checkers
forAll { (n: Int) =>
  (n > 0) ==> doubleIt(n) == (n * 2)
}
```
For either kind of property check, MaxDiscarded indicates the maximum number of discarded evaluations that will be allowed. As soon as one past this number of evaluations indicates it needs to be discarded, the property check will fail.

Note that the maximum size should be greater than or equal to the minimum size. This requirement is enforced by the PropertyCheckConfig constructor and the forAll methods of traits PropertyChecks and Checkers. In other words, it is enforced at the point both a maximum and minimum size are provided together.

object Table

Object containing one apply factory method for each TableFor<n> class.

For example, you could create a table of 5 rows and 2 colums like this:

import org.scalatest.prop.Tables._

val examples =
  Table(
    ("a", "b"),
    (  1,   2),
    (  2,   4),
    (  4,   8),
    (  8,  16),
    ( 16,  32)
  )

Because you supplied 2 members in each tuple, the type you'll get back will be a TableFor2. If you wanted a table with just one column you could write this:

val moreExamples =
  Table(
    "powerOfTwo",
         1,
         2,
         4,
         8,
         16
  )

Or if you wanted a table with 10 columns and 10 rows, you could do this:

val multiplicationTable =
  Table(
    ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j"),
    (  1,   2,   3,   4,   5,   6,   7,   8,   9,  10),
    (  2,   4,   6,   8,  10,  12,  14,  16,  18,  20),
    (  3,   6,   9,  12,  15,  18,  21,  24,  27,  30),
    (  4,   8,  12,  16,  20,  24,  28,  32,  36,  40),
    (  5,  10,  15,  20,  25,  30,  35,  40,  45,  50),
    (  6,  12,  18,  24,  30,  36,  42,  48,  54,  60),
    (  7,  14,  21,  28,  35,  42,  49,  56,  63,  70),
    (  8,  16,  24,  32,  40,  48,  56,  64,  72,  80),
    (  9,  18,  27,  36,  45,  54,  63,  72,  81,  90),
    ( 10,  20,  30,  40,  50,  60,  70,  80,  90, 100)
  )

The type of multiplicationTable would be TableFor10. You can pass the resulting tables to a forAll method (defined in trait PropertyChecks), to perform a property check with the data in the table. Or, because tables are sequences of tuples, you can treat them as a Seq.

def forAll(configParams: PropertyCheckConfigParam*): ConfiguredPropertyCheck
Performs a property check by applying the specified property check function to arguments supplied by implicitly passed generators, modifying the values in the implicitly passed PropertyGenConfig object with explicitly passed parameter values.
Performs a property check by applying the specified property check function to arguments supplied by implicitly passed generators, modifying the values in the implicitly passed PropertyGenConfig object with explicitly passed parameter values.
This method creates a ConfiguredPropertyCheck object that has six overloaded apply methods that take a function. Thus it is used with functions of all six arities. Here are some examples:
```
forAll (minSize(1), maxSize(10)) { (a: String) =>
  a.length should equal ((a).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String) =>
  a.length + b.length should equal ((a + b).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String) =>
  a.length + b.length + c.length should equal ((a + b + c).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String) =>
  a.length + b.length + c.length + d.length should equal ((a + b + c + d).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String, e: String) =>
  a.length + b.length + c.length + d.length + e.length should equal ((a + b + c + d + e).length)
}

forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String, e: String, f: String) =>
  a.length + b.length + c.length + d.length + e.length + f.length should equal ((a + b + c + d + e + f).length)
}
```

def whenever[T](condition: Boolean)(fun: ⇒ T)(implicit wa: WheneverAsserting[T]): Result
Evaluates the passed code block if the passed boolean condition is true, else throws DiscardedEvaluationException.
Evaluates the passed code block if the passed boolean condition is true, else throws DiscardedEvaluationException.
The whenever method can be used inside property check functions to discard invocations of the function with data for which it is known the property would fail. For example, given the following 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
}
```
```
import org.scalatest.prop.TableDrivenPropertyChecks._

val fractions =
  Table(
    ("n", "d"),
    (  1,   2),
    ( -1,   2),
    (  1,  -2),
    ( -1,  -2),
    (  3,   1),
    ( -3,   1),
    ( -3,   0),
    (  3,  -1),
    (  3,  Integer.MIN_VALUE),
    (Integer.MIN_VALUE, 3),
    ( -3,  -1)
  )
```
Imagine you wanted to check a property against this class with data that includes some value that are rejected by the constructor, such as a denominator of zero, which should result in an IllegalArgumentException. You could use whenever to discard any rows in the fraction that represent illegal arguments, like this:
```
import org.scalatest.matchers.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 === (0)

    f.denom should be > 0
  }
}
```
In this example, rows 6, 8, and 9 have values that would cause a false to be passed to whenever. (For example, in row 6, d is 0, which means d != 0 will be false.) For those rows, whenever will throw DiscardedEvaluationException, which will cause the forAll method to discard that row.
condition
the boolean condition that determines whether whenever will evaluate the fun function (condition is true) or throws DiscardedEvaluationException (condition is false)
fun
the function to evaluate if the specified condition is true

Note that the maximum size should be greater than or equal to the minimum size. This requirement is enforced by the PropertyCheckConfig constructor and the forAll methods of traits PropertyChecks and Checkers. In other words, it is enforced at the point both a maximum and minimum size are provided together.
