Fix webview_flutter Android integration tests and add Espresso #4147

bparrishMines · 2021-07-08T18:49:35Z

Integration tests weren't running since they were in the androidTestDebug folder and not a androidTest folder. This changes the folder name and fix the tests that weren't running.

Part of: flutter/flutter#83358

This test fails when running on Android, but it doesn't seem like there is anything we can do since a flag like this isn't supported on Android. At least according to the comment.

This test would stall on Android. For some reason, Android has different behavior when a window.open is called with a url with https:// vs not. It loads normally when using a URL with https://, but appends the url to the current url when it doesnt. (e.g. https://flutter.dev/ turns into https://flutter.dev/about:blank)

Fixed the weird bug where pageLoaded.complete() was called in the callback multiple times. From the Dart side, this caused a silent error and prevented the rest of the method calls from going through.

LGTM!

@stuartmorgan @blasten I think this PR is ready to go, but the tests seem to be pretty flaky. Is it alright to submit this if the integration tests require 2-3 runs to pass? Should I investigate more about why they are flaky or could I just skip the flaky ones for now?

Let's skip the flaky tests, with a bug filed to follow up (please CC me, and mark it team)

stuartmorgan-g · 2021-07-22T15:48:52Z

With #4172 landed, you'll need to have this PR remove webview_flutter from the exclude list (currently in .cirrus.yml, but #4183 moves it if that lands before this does).

bparrishMines · 2021-07-22T21:22:59Z

@stuartmorgan @blasten I skipped the flaky tests and added a link to flutter/flutter#86757. PTAL and I'll merge

Wow, that's a lot of flakes :(

But LGTM
