/**
 * {@code @TestMethodOrder} is a type-level annotation that is used to configure
 * a {@link #value MethodOrderer} for the test methods of the annotated
 * test class or test interface.
 *
 * 

In this context, the term "test method" refers to any method annotated with * {@code @Test}, {@code @RepeatedTest}, {@code @ParameterizedTest}, * {@code @TestFactory}, or {@code @TestTemplate}. * *

If {@code @TestMethodOrder} is not explicitly declared on a test class, * inherited from a parent class, or declared on a test interface implemented by * a test class, test methods will be ordered using a default algorithm that is * deterministic but intentionally nonobvious. * *

Example Usage

* *

The following demonstrates how to guarantee that test methods are executed * in the order specified via the {@link Order @Order} annotation. * *

 * {@literal @}TestMethodOrder(MethodOrderer.OrderAnnotation.class)
 * class OrderedTests {
 *
 *     {@literal @}Test
 *     {@literal @}Order(1)
 *     void nullValues() {}
 *
 *     {@literal @}Test
 *     {@literal @}Order(2)
 *     void emptyValues() {}
 *
 *     {@literal @}Test
 *     {@literal @}Order(3)
 *     void validValues() {}
 * }
 * 
* * @since 5.4 * @see MethodOrderer */ @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @Documented @Inherited @API(status = EXPERIMENTAL, since = "5.4") public @interface TestMethodOrder { /** * The {@link MethodOrderer} to use. * * @see MethodOrderer * @see MethodOrderer.Alphanumeric * @see MethodOrderer.OrderAnnotation * @see MethodOrderer.Random */ Class value(); }
