Composite Recipes
Recipes that include further recipes, often including the individual recipes below.
​Clean Up Assertions​
​JUnit Jupiter best practices​
​JUnit Jupiter migration from JUnit 4.x​
​Use Assertions#assume*(..) and Hamcrest's MatcherAssume#assume*(..)​
​Use MatcherAssert#assertThat(..)​
​Use Mockito JUnit Jupiter extension​
​Use OkHttp 3 MockWebServer for JUnit 5​
​Use Vert.x JUnit 5 Extension​
Recipes
​Add missing @ParameterizedTest annotation when @ValueSource is used or replace @Test with @ParameterizedTest​
​Cleanup JUnit imports​
​JUnit 4 @Category to JUnit Jupiter @Tag​
​JUnit 4 @RunWith to JUnit Jupiter @ExtendWith​
​JUnit 4 @RunWith(Enclosed.class) to JUnit Jupiter @Nested​
​JUnit 4 @RunWith(Parameterized.class) to JUnit Jupiter parameterized tests​
​JUnit 4 Assert To JUnit Jupiter Assertions​
​JUnit 4 ExpectedException To JUnit Jupiter's assertThrows()​
​JUnit 4 MockitoJUnit to JUnit Jupiter MockitoExtension​
​JUnit 5 inner test classes should be annotated with @Nested​
​JUnit TestName @Rule to JUnit Jupiter TestInfo​
​Make @TempDir fields non final​
​Make lifecycle methods non private​
​Migrate JUnit 4 @Test annotations to JUnit 5​
​Migrate JUnit 4 TestCase to JUnit Jupiter​
​Migrate JUnit 4 lifecycle annotations to JUnit Jupiter​
​Migrate from JUnit 4 @FixedMethodOrder to JUnit 5 @TestMethodOrder​
​OkHttp 3.x MockWebServer @Rule To 4.x MockWebServer​
​Pragmatists @RunWith(JUnitParamsRunner.class) to JUnit Jupiter Parameterized Tests​
​Remove JUnit 4 @RunWith annotations that do not require an @ExtendsWith replacement​
​Remove duplicates uses of @TestTemplate implementations for a single method​
​Replace fail() in try-catch blocks with Assertions.assertDoesNotThrow(() -> { ... })​
​Statically import JUnit Jupiter assertions​
​Use JUnit Jupiter @Disabled​
​Use JUnit Jupiter @TempDir​
​Use JUnit Jupiter Executable​
​Use XMLUnit Legacy for JUnit 5​
​Use wiremock extension​
​assertTrue(x instanceof y) to assertInstanceOf(y.class, x)​
