Flag to stop after first test failure

[sindresorhus]

From #9 (comment).

Does it makes sense to have this?

--bail, --fail-fast, other?

On that note, any thoughts on failing-fast by default? Any reason you'd want the test to complete before failing? I'm sure there are since test runners usually run to completion. Just useful to have this documented either way.

Yes, this would be a nice option to have.

I would leave this as an option, because AVA is a tool that enforces writing atomic tests. So, one failing test does not mean that all the other ones will fail too. But as an option, it is going to be useful for sure.

👍

On my own laptop I usually want the tests to fail fast, but in an CI environment I think it's good to run all tests and get a report of what didn't work.

What flag name do you prefer? bikeshedding

[joakimbeng]

I think I prefer --bail as it's in line with other test runners.

fail-fast means more to me as a programmer. I'd have no idea what bail meant.

[sindresorhus]

I don't really care what other test runners do. AVA exists because of those. I want something succinct as flag name.

👍 Then I agree with --fail-fast being a better name. Or maybe --abort-on-fail but that's too long to be good...

I like fail-fast.

I'd leave it as an option too, although I'm usually hitting ctrl +c whenever I see a fail test locally if there are time consuming tests (like in pageres). But most of the times, the tests are finished before that.

Also, +1 on fail-fast or something like it that makes it's intention clear. bail has never been that obvious to me.
