The choice to use annotations, at any level, isn't mandated by Java. That's mandated by choices made during design of the application (or maybe mandated by corporate code-style agreements).

As of Java 8 onwards, I've actually been writing far more "functional programming" style Java, so my code probably looks a lot more like Go - because I love lambda's. Some, typically more junior, developers do tend to struggle with lambdas though, in my experience.

The problem is: if a single case inside the for loop fails, the whole test is marked as red, and you have to go through the logs to identify which particular case failed (assuming you had the necessary logging set up).

I'd argue that's a good thing. Fail fast. I'd argue that tests shouldn't write any logs. The point of failure should make it explicitly clear at which point the test failed (at least down to the line). If this is within a loop/stream/lambda then yes, things can get complicated, but then you're just asking a developer to run the test case in debug, with the IDE set to halt execution on exception. Further, most JUnit assertions will allow you to put an explicit statement in the exception's message.

Logs are useful for support purposes, but there's nothing wrong with a developer hooking up to a remote JVM using JDPA to find out the internal state of an application.

The tooling (the in-IDE test runner, Jenkins, Surefire test reports, ...) does not accommodate this style very well.

There, we certainly agree. All of the tooling (except perhaps javac itself) is strongly opinionated about how it expects the application design to be laid out.

PS., no need to apologise for anything - we're both entitled to hold different opinions, that's the point of a debate! It might be that one (or both) reconsiders, but equally, we can still respect each other's opinions without any change.
