e2e iOS: Test runner doesn't exit #48601
Description
e2e version: 0.2.3
When using e2e with iOS unit tests, my test never quits and gets stuck running the event loop. Here is the backtrace:

Here is the loop:
while (!e2ePlugin.testResults) {
CFRunLoopRunInMode(kCFRunLoopDefaultMode, 1.f, NO);
}It seems e2ePlugin.testResults never is set to true.
