JUnit Jupiter

Best practices for JUnit Jupiter tests.

Recipes

• Add missing @ParameterizedTest annotation when @ValueSource is used or replace @Test with @ParameterizedTest
• Clean Up Assertions
• 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 Jupiter best practices
• JUnit Jupiter migration from JUnit 4.x
• 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
• Statically import JUnit Jupiter assertions
• Use Assertions#assume*(..) and Hamcrest's MatcherAssume#assume*(..)
• Use JUnit Jupiter @Disabled
• Use JUnit Jupiter @TempDir
• Use JUnit Jupiter Executable
• Use MatcherAssert#assertThat(..)
• Use Mockito JUnit Jupiter extension
• Use OkHttp 3 MockWebServer for JUnit 5
• Use Vert.x JUnit 5 Extension
• Use wiremock extension
