How can I use injection with Mockito and JUnit 5? In JUnit4 I can just use the @RunWith(MockitoJUnitRunner.class) Annotation. In JUnit5 is no @RunWith Annotation? There are different ways to use Mockito - I'll go through them one by one. Manually Creating mocks manually with Mockito::mock works regardless of the JUnit version (or test framework for that matter). Annotation Based Using the @Mock -annotation and the corresponding call to MockitoAnnotations::initMocks to create mocks works regardless of the JUnit version (or test framework for that matter but Java 9 could interfere here,

Is there a better way to assert that a method throws an exception in JUnit 5? Currently, I have to use an @Rule in order to verify that my test throws an exception, but this doesn't work for the cases where I expect multiple methods to throw exceptions in my test. steventrouble You can use assertThrows() , which allows you to test multiple exceptions within the same test. With support for lambdas in Java 8, this is the canonical way to test for exceptions in JUnit. Per the JUnit docs : import static org.junit.jupiter.api.Assertions.assertThrows; @Test void exceptionTesting() { MyException

I wrote a simple test method with JUnit 5: public class SimlpeTest { @Test @DisplayName("Some description") void methodName() { // Testing logic for subject under test } } But when I run mvn test , I got: ------------------------------------------------------- T E S T S ------------------------------------------------------- Running SimlpeTest Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.001 sec Results : Tests run: 0, Failures: 0, Errors: 0, Skipped: 0 Somehow, surefire didn't recognize that test class. My pom.xml looks like: <properties> <java.version>1.8</java.version>
