Tearing!

This test is actually failing:

use-context-selector/__tests__/02_tearing_spec.tsx

Line 45 in aa5c2d7

fireEvent.click(getAllByText('+1')[0]);

But the test didn't catch the error.

Yes, that was the whole point of having used changedBits=0.
Since v1.3, it won't work. v2-alpha won't work either. It's something we can't solve in userland as far as I understand currently.
The spec is kept in the repo (as well as 03_stale_props) to show the limitation. Those two specs are skipped.

Oh I guess I didn't fully understand this line in README :)

Tearing is only avoided within the Provider tree. A value outside the Provider will tear. (02_tearing_spec fails)

Feel free to close this.

@csr632 Would you have any suggestion to improve the line in README? I'm not confident it's well written.

How about #32

[dai-shi]

Yeah, that explains more carefully. Thanks for the suggestion. Closing this.
