Why @QuarkusMainTest

[argenstijn]

In the documentation quarkus states you should use @QuarkusMainTest for testing CLI. application I wonder why you would ever use it if you just could use @QuarkusTest. This latter one offers @InjectMocks/@Inject etc. capabilities. And it's easy to implement as well.

Is @QuarkusMainTest necessary to keep? Why not advice @QuarkusTest (for sure if you want to use mocks)?

You're right that @QuarkusMainTest is less generally useful than @QuarkusTest, but it does test some things that can't be tested with @QuarkusTest. If I was writing a CLI, I'd probably use a mix of @QuarkusTest (to test most of the business logic with the benefit of @Inject) and @QuarkusMainTest (to specifically exercise what happens in the main method and the different launch parameters).

@QuarkusMainTest allows you to specify command line arguments for each test method and launch the same application multiple times in the same test class.
