KIF compatibility #52

Open maciekish opened 9 years ago

maciekish commented 9 years ago

Hi, I'm trying to use WYPopoverController together with KIF tests. Unfortunately it crashes when trying to display a popover. I'm trying to run this on the iPad 2 iOS 8.1 simulator. If i just hit ⌘R and tap the UI element that causes a popover to appear, it works perfectly. But if i press ⌘Uto run the tests and tap the search bar it crashes. I also tried manually tapping the search bar before KIF takes any actions (by making KIF wait using [tester waitForTimeInterval:60]) and it crashes then as well, so at least we can rule out KIF tapping the wrong element or tapping it in the wrong way.

It crashes on [_inView.window addSubview:_backgroundView];

Full backtrace:

Normally this sort of issue arises due to swizzling that KIF is doing under the surface. It's not a library that we use on any of the projects I'm working on. Were you able to resolve this?

maciekish commented 9 years ago

Unfortunately no, the issue remains. Any idea about what to try please?

vitalys commented 9 years ago

@maciekish could you provide simple test project that reproduces the problem? Otherwise a chance to get this problem fixed really small.
