# PropertyChecks

#### trait PropertyChecks extends TableDrivenPropertyChecks with GeneratorDrivenPropertyChecks

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 should be === 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) =>
      evaluating {
        new Fraction(n, d)
      } should produce [IllegalArgumentException]
    }

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

9. #### def asInstanceOf [T0] : T0

   This method is used to cast the receiver object to be of type `T0`.

   This method is used to cast the receiver object to be of type `T0`.

   Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression`1.asInstanceOf[String]` will throw a `ClassCastException` at runtime, while the expression`List(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.

   returns

     the receiver object.

   definition classes: Any

10. #### def clone () : AnyRef

    This method creates and returns a copy of the receiver object.

    This method creates and returns a copy of the receiver object.

    The default implementation of the `clone` method is platform dependent.

    returns

      a copy of the receiver object.

    definition classes: AnyRef

11. #### def eq (arg0: AnyRef) : Boolean

    This method is used to test whether the argument (`arg0`) is a reference to the receiver object (`this`).

    This method is used to test whether the argument (`arg0`) is a reference to the receiver object (`this`).

    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`).

    arg0

      the object to compare against this object for reference equality.

    returns

      `true` if the argument is a reference to the receiver object; `false` otherwise.

    attributes: final
    definition classes: AnyRef

12. #### def equals (arg0: Any) : Boolean

    This method is used to compare the receiver object (`this`) with the argument object (`arg0`) for equivalence.

    This method is used to compare the receiver object (`this`) with the argument object (`arg0`) for equivalence.

    The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation]: * It is reflexive: for any instance `x` of type `Any`, `x.equals(x)` should return `true`. * It is symmetric: for any instances `x` and `y` of type `Any`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`. * It is transitive: for any instances `x`, `y`, and `z` of type `AnyRef` if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.

    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)`).

    arg0

      the object to compare against this object for equality.

    returns

      `true` if the receiver object is equivalent to the argument; `false` otherwise.

13. #### def finalize () : Unit

    This method is called by the garbage collector on the receiver object when garbage collection determines that there are no more references to the object.

    This method is called by the garbage collector on the receiver object when garbage collection determines that there are no more references to the object.

    The details of when and if the `finalize` method are invoked, as well as the interaction between `finalize`and non-local returns and exceptions, are all platform dependent.

63. #### def hashCode () : Int

    Returns a hash code value for the object.

    Returns a hash code value for the object.

    The default hashing algorithm is platform dependent.

    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)`). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the `equals` method.

    returns

      the hash code value for the object.

64. #### def isInstanceOf [T0] : Boolean

    This method is used to test whether the dynamic type of the receiver object is `T0`.

    This method is used to test whether the dynamic type of the receiver object is `T0`.

    Note that the test result of the test is modulo Scala's erasure semantics. Therefore the expression`1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. 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.

    returns

      `true` if the receiver object is an instance of erasure of type `T0`; `false` otherwise.

    Returns a `MaxSize` property check configuration parameter containing the passed value, which specifies the maximum size parameter to provide to ScalaCheck, which it will use when generating objects for which size matters (such as strings or lists).

    Returns a `MaxSize` property check configuration parameter containing the passed value, which specifies the maximum size parameter to provide to ScalaCheck, which it will use when generating objects for which size matters (such as strings or lists).

    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.

77. #### def whenever (condition: Boolean)(fun: ⇒ Unit) : Unit

    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.ShouldMatchers._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
          }
        }

    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
