Problem: The magic globals `it`, `describe`, etc., are more trouble than they are worth. - Hooking into `after_each` requires `getfenv()` hacks. - They confuse luals/emmylua, because the top-level `.luarc.json` isn't merged with `test/.luarc.json` (apparently a luals limitation?) - They totally defeat discoverability because the user just has to "know" about the various magic symbols. So they harm DX, which means they serve no purpose at all. Solution: - Expose the test API from `testutil`, so tests can call `t.it()`, `t.describe()`, etc., in the conventional way. - Drop `getfenv()` hacks. - Drop the `setfenv()` injection in `load_chunk`. - Drop `test/_meta.lua`.
"Error" in error messages is redundant. Just provide the context, don't say "Error ...".
Before calling "attach" a screen object is just a dummy container for (row, col) values whose purpose is to be sent as part of the "attach" function call anyway. Just create the screen in an attached state directly. Keep the complete (row, col, options) config together. It is still completely valid to later detach and re-attach as needed, including to another session.
Specifically, functions that are run in the context of the test runner are put in module `test/testutil.lua` while the functions that are run in the context of the test session are put in `test/functional/testnvim.lua`. Closes https://github.com/neovim/neovim/issues/27004.

This is the first installment of a multi-PR series significantly refactoring how highlights are being specified. The end goal is to have a base set of 20 ish most common highlights, and then specific files only need to add more groups to that as needed. As a complicating factor, we also want to migrate to the new default color scheme eventually. But by sharing a base set, that future PR will hopefully be a lot smaller since a lot of tests will be migrated just simply by updating the base set in place. As a first step, fix the anti-pattern than Screen defaults to ignoring highlights. Highlights are integral part of the screen state, not something "extra" which we only test "sometimes". For now, we still allow opt-out via the intentionally ugly screen._default_attr_ids = nil The end goal is to get rid of all of these eventually (which will be easier as part of the color scheme migration)
