The unit test doesn't consistently fail on current master.

[iamphill]

@hnrch02 I can't get the tests to fail? Rebased with master to get latest changes and ran the tests so many times...

[hnrch02]

That's kinda bad since we then can't detect any regression about this.

[iamphill]

Tell me about it.
It used to reliably fail when the timing was longer, could put it back to the previous timing?

[hnrch02]

Yeah, try that. Will be necessary at some point anyways because of #14851.

Think I've found the issue with the unit tests. The transitions are disabled on https://github.com/twbs/bootstrap/blob/master/js/tests/index.html#L55

And then in the tooltip.js file it fires the complete func immediately if $.support.transition is false https://github.com/twbs/bootstrap/blob/master/js/tooltip.js#L214-L218

I can reliably recreate the issue & see the fix in the visual tests. Obviously not great... Will see what I can do to get these tests to reliably fail.

[hnrch02]

Yeah, testing without transitions is hard. I'll merge this anyway as we know it fixes the issue. If you come up with a solution though please do share.
