/**
 * VerificationWithTimeout is a {@link VerificationMode} that allows combining existing verification modes with 'timeout'. E.g:
 *
 * 
 * verify(mock, timeout(100).times(5)).foo();
 *
 * verify(mock, timeout(100).never()).bar();
 *
 * verify(mock, timeout(200).atLeastOnce()).baz();
 * 
 *
 * This is similar to {@link VerificationAfterDelay after()} except this assertion will immediately pass if it becomes true at any point,
 * whereas after() will wait the full period. Assertions which are consistently expected to be initially true and potentially become false
 * are deprecated below, and after() should be used instead.
 *
 * 
 * See examples in javadoc for {@link Mockito#verify(Object, VerificationMode)}
