Is there a reason you shouldn't always use the -A CLI option?

if the test alias uses test-runner, you may not want the main aspect of it 🙂

Could you clarify what you mean? What is test-runner? And what is the main aspect of it?

Sorry, I should be clearer, you may not want the :main-opts option to kick in.

Ah that makes sense. Is that the only reason?
