Method Detail

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.
