com.github.robtimus.junit.support.PredicateAssertions

public final class PredicateAssertions
extends Object

A collection of utility methods that support asserting conditions on objects using predicates. These methods are like Assertions.assertTrue(boolean) and Assertions.assertFalse(boolean), but use an actual object that's not always true or false. As a result, the assertions in this class provide more information about why assertions fail.
