Method Detail

accepts

@SafeVarargs
public final PredicateAssert<T> accepts(T... values)

Description copied from class: AbstractPredicateAssert

Verifies that the Predicate evaluates all given values to true.

Example :

 Predicate<String> ballSportPredicate = sport -> sport.contains("ball");

 // assertion succeeds:
 assertThat(ballSportPredicate).accepts("football")
                               .accepts("football", "basketball", "handball");

 // assertions fail because of curling :p
 assertThat(ballSportPredicate).accepts("curling")
 assertThat(ballSportPredicate).accepts("football", "basketball", "curling");

Overrides:

accepts in class AbstractPredicateAssert<PredicateAssert<T>,T>

Parameters:

values - values the actual Predicate should accept.

Returns:

this assertion object.

rejects

@SafeVarargs
public final PredicateAssert<T> rejects(T... values)

Description copied from class: AbstractPredicateAssert

Verifies that the Predicate evaluates all given values to false.

Example :

 Predicate<String> ballSportPredicate = sport -> sport.contains("ball");

 // assertion succeeds:
 assertThat(ballSportPredicate).rejects("curling")
                               .rejects("curling", "judo", "marathon");

 // assertion fails because of football:
 assertThat(ballSportPredicate).rejects("football");
 assertThat(ballSportPredicate).rejects("curling", "judo", "football");

Overrides:

rejects in class AbstractPredicateAssert<PredicateAssert<T>,T>

Parameters:

values - values the actual Predicate should reject.

Returns:

this assertion object.
