X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/8acc22f11480dab297ad31fa80fa63bea15066c6?ds=sidebyside;hp=8acc22f11480dab297ad31fa80fa63bea15066c6

Add black-primer unittests (#1426)

* Add black-primer unittests

- Get this tool covered with some decent unittests for all unittests wins
- Have a CLI and lib test class
- Import it from `test_black.py` so we always run tests
- Revert typing asyncio.Queue as Queue[str] so we can work in 3.6
- **mypy**: Until black > 3.6 disallow_any_generics=False for primer code

Test:
- Run tests: `coverage run tests/test_primer.py` or `coverage run -m unittest`
```

* Use ProactorEventLoop for Windows + fix false path for Linux

* Set Windows to use ProactorEventLoop in  to benefit all callers

* sys.platform seems to not having the loop applied - So type ignore and use platform.system() gate

* Have each test loop correctly set to ProactorEventLoop on Windows for < 3.8 too
