I added the jupiter, mockito and jupiter engine to the pom.xml file as you can see in the following clipboard:

My tests are under the src/test/java/com/example/myapp/testingit package:

If I run the mvn test it does not find any tests:

Although I have tests:

What goes wrong?

CodePudding user response：

You're missing the junit-platform-surefire-provider dependency. Additionally, you have mismatching versions of junit-jupiter-api and junit-jupiter-engine, which may not be critical, but is probably a bad idea that can lead to hard-to-find bugs later on. You can solve both these issues by using the aggregate junit-jupiter dependency:
