在 Fastlane 上运行时，`twoFingerTap()` 和 `tap(withNumberOfTaps:1 numberOfTouches:2)` 有什么区别？

Question

I have been working with UI test on iOS, and using XCUITest on swift. In one test I need to tap with two fingers on the screen at the same time. I used twoFingerTap() . The test passes when I run it from Xcode. But running by command line with fastlane it fails. Then, a coworker suggested to change it to tap(withNumberOfTaps:1 numberOfTouches:2) , and it works when running on both ways. I have no idea why this different behavior from actions that should be doing the same thing. Somebody knows?

First attempt:

appUnderTest.twoFingerTap()

Second attempt:

appUnderTest.tap(withNumberOfTaps: 1, numberOfTouches: 2)

Fastlane Command:

bundle exec fastlane scan --scheme "MyApp" --device "iPhone 13" --force_quit_simulator --prelaunch_simulator --reset_simulator

Answer 1

twoFingerTap() does not tap twice, it simulates tapping with two fingers at the same time, I don't really understand how it works locally. To achieve what you want you need to use doubleTap() . Unless you meant that you actually want to do two-finger tap, in this case your question is not stated properly.

Answer 2

These two methods should be equivalent (either in Xcode, or when running the simulator via the command line as Fastlane does). I'd suggest filing a bug with Apple.
