This is quite possibly multiple bugs, so for now let's focus on https://build.chromium.org/p/chromium.android/builders/Lollipop%20Phone%20Tester and https://build.chromium.org/p/chromium.android/builders/Marshmallow%2064%20bit%20Tester


Both of these are failing on org.chromium.chrome.browser.widget.bottomsheet.BottomSheetContentControllerTest#testSelectContent fairly frequently.

Theresa, it looks like you added BottomSheetContentControllerTest in https://codereview.chromium.org/2861453002. Can you take a look at the testSelectContent() failures?

When did this start failing?

e.g. links to first builds? We're actively developing this feature, and it sounds like something regressed recently.

first failure on marshmallow: https://build.chromium.org/p/chromium.android/builders/Marshmallow%2064%20bit%20Tester/builds/11826

I'll get back to you about lollipop in a minute.

first failure on lollipop: https://build.chromium.org/p/chromium.android/builders/Lollipop%20Phone%20Tester/builds/11763

It looks like that test has been failing consistently since it landed. I'm not sure why the CQ didn't catch it, but I'll disable for now and investigate separately. Hopefully that unblocks debugging what's wrong with the other bots.

Will land soon: https://codereview.chromium.org/2875813002/

The two tests affected in comment #9 are passing (or not running).

Lollipop phone tester is now only failing on unit_tests
Mashmallow 64bit tester is failing browser_side_navigation_chrome_public_test_apk 
Neither test ran on tablets so those bots are unaffected

cc'ing today's sheriffs as an FYI.

This bug has gotten stale. I'm closing it out.
