Applies the passed property check function to each row of this TableFor17
.
If the property checks for all rows succeed (the property check function returns normally when passed
the data for each row), this apply
method returns normally. If the property check function
completes abruptly with an exception for any row, this apply
method wraps that exception
in a TableDrivenPropertyCheckFailedException
and completes abruptly with that exception. Once
the property check function throws an exception for a row, this apply
method will complete
abruptly immediately and subsequent rows will not be checked against the function.

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String]
will throw a ClassCastException
at runtime, while the expressionList(1).asInstanceOf[List[String]]
will not. In the latter example, because the type argument is erased as
part of compilation it is not possible to check whether the contents of the list are of the requested typed.

The eq
method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef
:
* It is reflexive: for any non-null instance x
of type AnyRef
, x.eq(x)
returns true
.
* It is symmetric: for any non-null instances x
and y
of type AnyRef
, x.eq(y)
returns true
if and
only if y.eq(x)
returns true
.
* It is transitive: for any non-null instances x
, y
, and z
of type AnyRef
if x.eq(y)
returns true
and y.eq(z)
returns true
, then x.eq(z)
returns true
.
Additionally, the eq
method has three other properties.
* It is consistent: for any non-null instances x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.
* For any non-null instance x
of type AnyRef
, x.eq(null)
and null.eq(x)
returns false
.
* null.eq(null)
returns true
.
When overriding the equals
or hashCode
methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2
), they
should be equal to each other (o1 == o2
) and they should hash to the same value (o1.hashCode == o2.hashCode
).

This method is used to compare the receiver object (this

If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to override hashCode
to ensure that objects
that are "equal" (o1.equals(o2)
returns true
) hash to the same
scala.Int
(o1.hashCode.equals(o2.hashCode)
).

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)
) yet
not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)

A table with 17 columns.
For an introduction to using tables, see the documentation for traitTableDrivenPropertyChecks.
This table is a sequence of
Tuple17
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
TableFor17
is via anapply
factory method in theTable
singleton object provided by theTables
trait. Here's an example: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. Theapply
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 theapply
method will complete abruptly with aTableDrivenPropertyCheckFailedException
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 aforAll
method provided by traitTableDrivenPropertyChecks
. TheforAll
method takes aTableFor17
as its first argument, then in a curried argument list takes the property check function. It invokesapply
on theTableFor17
, passing in the property check function. Here's an example:Because
TableFor17
is aSeq[(A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q)]
, you can use it as aSeq
. For example, here's how you could get a sequence of optional exceptions for each row of the table, indicating whether a property check succeeded or failed on each row of the table:Note: the
failureOf
method, contained in theFailureOf
trait, will execute the supplied code (a by-name parameter) and catch any exception. If no exception is thrown by the code,failureOf
will result inNone
, indicating the "property check" succeeded. If the supplied code completes abruptly in an exception that would normally cause a test to fail,failureOf
will result in aSome
wrapping that exception. For example, the previous for expression would give you:This shows that all the property checks succeeded, except for the one at index 7.
