justinleet opened a new pull request #1554: METRON-2307: Migrate to JUnit5 URL: https://github.com/apache/metron/pull/1554 ## Contributor Comments Moves to JUnit 5. This came out of my forever ago desire to look into JUnit5 extensions to share test infra (Kafka, ZK, etc.) across our test classes, rather than spin up for each class. - Migrates everything to JUnit5 annotations. - Migrates everything to JUnit5 assertions. This includes making everything `assertThrows` - The only `@Rule`s left are for temporary directories. This feature is experimental in JUnit5 (although I do use it once for a `@ClassRule` one. We could potentially migrate over, it's not like it'd be a huge deal to upgrade to whatever they choose in the future. - PowerMock is gone. Doesn't work in JUnit 5. Various methods are added to source to be able to mock out / spy on / whatever to get it to work. Tried to be pretty minimal about this change, since it hits outside of tests. - I believe a single test got deleted: One for a two line method in `MetronRestApplication`, iirc. Didn't seem super helpful to test that it ran the `SpringApplication`. Build works (potentially barring the last couple cleanup commits which are going through my personal Travis), but I still need to spin it up on dev. I'm not super thrilled about this being a large PR, but it was an enormous pain that kept finding things backwards in modules I thought I'd already cleared. It could probably be split out, but I'll be honest: If I see that request, I'll probably ignore it for awhile. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
