Method Detail

accepts

public SELF accepts(T... values)

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");

Parameters:

values - values the actual Predicate should accept.

Returns:

this assertion object.

Throws:

AssertionError - if the actual Predicate does not accept all the given Iterable's elements.

rejects

public SELF rejects(T... values)

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");

Parameters:

values - values the actual Predicate should reject.

Returns:

this assertion object.

Throws:

AssertionError - if the actual Predicate accepts one of the given Iterable's elements.

acceptsAll

public SELF acceptsAll(Iterable<? extends T> iterable)

Verifies that the Predicate evaluates all given Iterable's elements to true.

Example :

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

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

 // assertion fails because of curling :p
 assertThat(ballSportPredicate).acceptsAll(list("football", "basketball", "curling"));

Parameters:

iterable - Iterable whose elements the actual Predicate should accept.

Returns:

this assertion object.

Throws:

AssertionError - if the actual Predicate does not accept all the given Iterable's elements.

rejectsAll

public SELF rejectsAll(Iterable<? extends T> iterable)

Verifies that the Predicate evaluates all given Iterable's elements to false.

Example :

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

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

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

Parameters:

iterable - Iterable whose elements the actual Predicate should reject.

Returns:

this assertion object.

Throws:

AssertionError - if the actual Predicate accepts one of the given Iterable's elements.
