Hi all,
I'm using UI Testing and performance testing in XCode 7 to test against the application. I used following XCTest API to run performance test.
measureMetrics(self.dynamicType.defaultPerformanceMetrics(), automaticallyStartMeasuring: false, forBlock: {
//someFunc
})
someFunc() {
//some preparation before star measuring
self.startMeasuring()
let lastView = app.otherElements["uitest.performancelogendingview"]
expectationForPredicate(exists, evaluatedWithObject: lastView, handler: nil)
waitForExpectationsWithTimeout(60, handler: nil)
self.stopMeasuring()
// some tear down work
}
It works well on simulator. But if it runs on device, there's a problem. The test would launch and process correctly. However every time just after repeat 10 runs, the test fails, before it tears down. Is this caused by a crash? Fail can only be observed on device. It's reproducible stably.

Could anyone help to give any suggestions? Thank you!
