Why did this change from >= to ==? It seems safer to use >= since otherwise we
may end up in a situation where this loop does not terminate.

[prasadt, 2011/10/28 20:19:35]

I think the situation is the same before too, as you could have a test that
creates one few tabs. Yes, it could be a problem is some test consider more tabs
etc than what's passed in to be a success. But I don't see that to be the case.

I had to make the change because for the uninstall case, I'm looking for the
count to go down to the expected number and not up. So >= will bail out right
away which is not what I want.

I would use EXPECT_EQ so the rest of the tests can continue running.

[prasadt, 2011/10/28 20:19:35]

Done.

This won't actually affect other tests as these are browser tests and each runs
in its own process.
