After our mobile web upgrade to React 16.0.x, our automation input box sendkeys got failure on iOS

[Charles Huang]

Protractor: 3.0.0

selenium-webdriver: 3.5.0

Test device: Saucelabs iPhone simulator iOS 10.0

Mobile web build by React 10.6.x

Our mobile web has input box which build React controlled input, after we upgrade the React from 10.5.x to 10.6.x

Our automation test got failure when we submit the input box value to our backend.

We used the saucelabs to execute our automatino testing. On the saucelabs recording video, we can see the input has value be presented.

We used webdriver sendkeys function to insert value to the input box element. Then click the submit button. We check our backend log, the input box value is empty.

I try to manual the simulator on saucelabs, use the soft keyboard to type the value and click submit. it works.

I also try use the Android emulator to run the same test, it works too. It seems the sendkeys function didn't trigger the React properly event. so the React component think the input value didn't be changed.

I saw the React changelog and noticed the upgrade include some input improvment.

Does anyone face the same issue and know hope to fix or some workaround.

Thanks,
