We're getting a lot of users asking for a dedicated JUnit 5 starter POM, but I'd rather we investigate how we can upgrade our existing starter to JUnit 5.

We need to consider the following use-cases:

• For green field applications it would be nice to use only JUnit 5. It will be confusing if there are multiple @Test imports.

• For existing applications it would be nice if they can migrate to JUnit 5 in their own time. An upgraded application should continue to work. It's likely we'll need to support this type of hybrid application for some time.

• It's possible that some users might want to remain on JUnit 4 only. We'll need to consider if this is something we want to support, or if it's something they should do themselves.
