Class HamcrestCondition<T>

  • All Implemented Interfaces:
    Descriptable<Condition<T>>
    public class HamcrestCondition<T>
extends Condition<T>
    Allows to use a Hamcrest matcher as a condition. Example: 
     Condition<String> aStringContainingA = new HamcrestCondition<>(containsString("a"));
 
 // assertions will pass
 assertThat("abc").is(aStringContainingA);
 assertThat("bc").isNot(aStringContainingA);
 
 // assertion will fail
 assertThat("bc").is(aStringContainingA);
    Since:
    2.9.0 / 3.9.0
