  • Constructor Details

    • DoublePredicateAssert

      public DoublePredicateAssert(DoublePredicate actual)

  • Method Details

    • assertThatDoublePredicate

      public static DoublePredicateAssert assertThatDoublePredicate(DoublePredicate actual)

    • toPredicate

      private static Predicate<Double> toPredicate(DoublePredicate actual)

    • accepts

      public DoublePredicateAssert accepts(double... values)
      Verifies that DoublePredicate evaluates all the given values to true.

      Example : 

       DoublePredicate tallSize = size -> size > 1.90;

 // assertion succeeds:
 assertThat(tallSize).accepts(1.95, 2.00, 2.05);

 // assertion fails:
 assertThat(tallSize).accepts(1.85, 1.95, 2.05);
      Parameters:
      values - values that the actual Predicate should accept.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual Predicate does not accept all given values.

    • rejects

      public DoublePredicateAssert rejects(double... values)
      Verifies that DoublePredicate evaluates all the given values to false.

      Example : 

       DoublePredicate tallSize = size -> size > 1.90;

 // assertion succeeds:
 assertThat(tallSize).rejects(1.75, 1.80, 1.85);

 // assertion fails because of 1.90 size:
 assertThat(tallSize).rejects(1.80, 1.85, 1.90);
      Parameters:
      values - values that the actual Predicate should reject.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual Predicate accepts one of the given values.
