Examples

AnnotationAssertions

Assertion factory methods that allow testing the annotations of various types.

Allow asserting that an annotation is present and also to perform assertions on the annotation itself:

@Test
void isAnnotatedAsTransactionalWithNoRollbackForException() {
    assertHasAnnotation(NotificationPublisher.class, Transactional.class)
        .extracting(Transactional::noRollbackFor)
        .isEqualTo(Exception.class);
}

Similarly, for Method:

@ParameterizedTest
@MethodSource
void isAnnotatedAsTransactionalWithNoRollbackForException(Method method) throws Exception {
    assertHasAnnotation(method, Transactional.class)
        .extracting(Transactional::noRollbackFor)
        .isEqualTo(Exception.class);
}

Similarly, for Field:

@ParameterizedTest
@MethodSource
void isAnnotatedAsDigitsWithTwoFractionalDigits(Field field) {
    assertHasAnnotation(field, Digits.class)
        .extracting(Digits::fraction)
        .isEqualTo(2);
}
