SpringBoot Avoid repeated class lookups in tests

Hi 👋

I've been profiling our test suites these days and noticed a very small, but probably avoidable, overhead in RestDocsTestExecutionListener

Feel free to decline if this is problematic in any scenario I'm currently not seeing. It's really minor.

Cheers, Christoph

Thanks, @dreis2211. I don't foresee any problems with your proposed change. I have no idea why I wrote it like this originally. I guess I just thought that the CPU needed something to do…

Would you mind if I push another commit that does the same for MockWebServiceServerTestExecutionListener? Or do you want me to open a separate PR?

Thanks again Christoph!

I edited your commit to fix the check there.
