Detox: Tap on Switch component fails in around 20% of the time

Created on 10 Feb 2020  路  15Comments  路  Source: wix/Detox

Description

I have a React-native Switch component that I need to tap on in an e2e test. In around 20% of the tests I can see a tap in the simulator, but the tap is not registered by the app.

  • [x] I have tested this issue on the latest Detox release and it still reproduces

Reproduction

Here is a repo that demonstrates the issue: https://github.com/compojoom/rnDetoxActionSheetBug/tree/switch-bug

I'm rendering a switch component several times on the screen. And in my test I'm trying to press those components.
https://github.com/compojoom/rnDetoxActionSheetBug/blob/switch-bug/App.js#L29;L57

https://github.com/compojoom/rnDetoxActionSheetBug/blob/switch-bug/e2e/firstTest.spec.js#L6;L36

This doesn't always happen. Sometimes the test completes successfully... On Android it seems to register the taps all the time.

Expected behavior

I would expect that the App would always register the tap as it happens when one manually presses the switch.

Screenshots

here is a video:

Hmm
I'm not sure the issue here is with Detox. It could be React Native shenanigans. As you can see, the tap is sent correctly, and for a fraction of a second, the switch reacts to it (it flickers).

Do you mind quickly creating a native project, throwing a few switches in storyboard and trying to tap on them with Detox?

LeoNatan picture LeoNatan on 11 Feb 2020

For example, RN is changing the value just after the user touches it:
https://github.com/facebook/react-native/blob/7bd1abec35f0aff0dddf0c1a68f79da29e00acdb/React/Views/RCTSliderManager.m#L45

Could be buggy logic in there.

Hey @LeoNatan!
What do you mean with "throwing a few switches in storyboard"? I do have a react-native project with few switches in it. The video is made with this: https://github.com/compojoom/rnDetoxActionSheetBug/blob/switch-bug/App.js#L29;L57

compojoom picture compojoom on 11 Feb 2020

I meant native project, in Xcode, not RN.

LeoNatan picture LeoNatan on 11 Feb 2020

Ah, ok. I'll try. It will take me some time as I've never created a native project :)

Do we have a guide on integrating detox in native projects? I didn't see anything in the docs folder.

compojoom picture compojoom on 11 Feb 2020

Nope, should be exactly the same. Since there is no package.json, just create one and add the detox config. But build and test should be the same.

LeoNatan picture LeoNatan on 11 Feb 2020

Ok, created the requested native project. https://github.com/compojoom/SwitchDetoxNative

The issue doesn't seem to happen there. The test has tapped on the Switch Components around 60 times and every time they respond fine.

So we are categorizing this as a RN bug now?

Great, thanks for following through.
It sounds like it is.

LeoNatan picture LeoNatan on 12 Feb 2020

Hm, but how would someone fix this?
I've never been able to reproduce this manually. I've been tapping on those switch components like crazy and they always respond.

It's only when we run it through a e2e tests that those fail from time to time.

compojoom picture compojoom on 12 Feb 2020

That鈥檚 a good question. We haven鈥檛 seen this either in any of our e2e tests here in Detox or internal ones.

To me it looks like some incorrect state management could be causing it. The reason I suspected in the first place is that I saw the RN switch flicker somewhat on the touch, meaning the native control gets the event. So, somehow, RN fudges the state and causes the value to reset. RN developers should look at the code and think when this could happen. Perhaps edge cases where state mutates early on (in the video it reproduces on the first one).

LeoNatan picture LeoNatan on 12 Feb 2020

Ok, I'll open an issue in the react-native repo

Great. You can post the issue here if you want.
