Type Members

  1. 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.

  2. 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.

  3. case class MaxSize (value: Int) extends PropertyCheckConfigParam with Product with Serializable

    A PropertyCheckConfigParam that 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).

  4. case class MinSize (value: Int) extends PropertyCheckConfigParam with Product with Serializable

    A PropertyCheckConfigParam that specifies the minimum size parameter to provide to ScalaCheck, which it will use when generating objects for which size matters (such as strings or lists).

  5. case class MinSuccessful (value: Int) extends PropertyCheckConfigParam with Product with Serializable

    A PropertyCheckConfigParam that specifies the minimum number of successful property evaluations required for the property to pass.

  6. case class PropertyCheckConfig (minSuccessful: Int, maxDiscarded: Int, minSize: Int, maxSize: Int, workers: Int) extends Product with Serializable

    Configuration object for property checks.

  7. class PropertyCheckConfigParam extends AnyRef

    Abstract class defining a family of configuration parameters for property checks.

  8. case class Workers (value: Int) extends PropertyCheckConfigParam with Product with Serializable

    A PropertyCheckConfigParam that specifies the number of worker threads to use when evaluating a property.

    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)
    }

    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.

    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
