I see the plugin has a custom test format, maybe that only makes sense to add when this is ready to contribute upstream?

It makes sense to add them here too, I just don't have time to write them now. So I manually tested the rules in vim like a cave man.

Just saw the test format... I'll add it here, or maybe I try to submit a PR to nvim-context itself, however I'm not sure it they will accept since this isn't on nvim-treesitter yet.

I wrote a test, I tried to run it on nvim-treesitter-context but it needs the language to be already in nvim-treesitter to execute the tests.

So I think the tests can be sent when this query get upstream and this can be merged now.
