Hi All! In my tested app I'm using a WebGL based library I need to test. Since I cannot use visual testing for various reasons, I have exposed the library to the global namespace and I'm trying to spy on calls to this library methods. Some methods are asynchronous, though. I wasn't able so far to create a spy on a library method and verify its returned RESOLVED value was correct. If not - I need this to fail my whole test, naturally (some tests remain green though parts are failing):
