Proposal

cleanup junit limitation for document

details

https://java.testcontainers.org/test_framework_integration/junit_5/

According to the documentation, it still says that a JUnit 4 dependency is required.

Since this module has a dependency onto JUnit Jupiter and on Testcontainers core, which has a dependency onto JUnit 4.x, projects using this module will end up with both, JUnit Jupiter and JUnit 4.x in the test classpath.

However, these changes should have completely removed the dependency on JUnit 4.

• since GenericContainer run from Jupiter tests shouldn't require JUnit 4.x library on runtime classpath #970
  • and Remove JUnit 4 support #10805 ,
