FWIW I ran browser_tests and content_browsertests a while ago on my machine.

https://bugs.chromium.org/p/chromium/issues/detail?id=861644
https://bugs.chromium.org/p/chromium/issues/detail?id=861657

At that time above two failures were all failures I found (and fixed).

Ah, I got confused and thought we only did this for ServiceWorker* tests. Thanks, I didn't realize you already did this for everything.

Would you be able to run it on the CQ to see if everything is really green everywhere?

Sure. Assigning to myself for now.

yhirano: FYI, we expect to already pass almost all tests with --enable-features="ServiceWorkerServicification" (unless there are failures we wouldn't see locally like Android-only failures etc).

We are still working on content_unittests at  issue 860361 .

Ran on trybots: https://chromium-review.googlesource.com/c/chromium/src/+/1146529

Looks like we have some failures:

content_browsertests

PreviewsStateBrowserTest.ShouldEnableLoFiModeOn
PreviewsStateBrowserTest.ShouldEnableLoFiModeNavigateBackThenForward
PreviewsStateBrowserTest.ShouldEnableLoFiModeReload

browser_tests on ChromeOS and Linux

ResourceLoadingHintsBrowserTest.ResourceLoadingHintsHttpsWhitelistedRedirectToHttps
ResourceLoadingHintsBrowserTest.ResourceLoadingHintsHttpsWhitelisted
PreviewsNoScriptBrowserTest.NoScriptPreviewsEnabled
PreviewsNoScriptBrowserTest.NoScriptPreviewsEnabledHttpRedirectToHttps

And some layout tests not covered by the virtual test suite? I'm not sure if it's out-of-scope of this issue though.

It looks like the finch config only runs browser_tests with the flag.

At https://chromium-review.googlesource.com/c/chromium/src/+/1147891, the failures are:

content_browsertests on Android (flake?):
MSE_ExternalClearKey/EncryptedMediaTest.FrameSizeChangeVideo/0

browser_tests on others:
PreviewsNoScriptBrowserTest.NoScriptPreviewsEnabled
PreviewsNoScriptBrowserTest.NoScriptPreviewsEnabledHttpRedirectToHttps

Actually not sure about the first sentence of c#8.

Regarding PreviewsNoScriptBrowserTests:

It looks like Previews use NavigationData to store their data. Uploaded a fix.

S13nServiceWorker: Populate NavigationData when NetworkService is disabled

When S13nServiceWorker is enabled but NetworkService is disabled,
NavigationURLLoaderImpl actually uses URLRequest when a navigation
is not intercepted. In that case we have a NavigationData and we can
populate it to NavigationHandle. Since some features like Previews
use NavigationData to store their data, it would be better to
populate it if possible.

This fixes following browser_tests:
- PreviewsNoScriptBrowserTest.NoScriptPreviewsEnabled
- PreviewsNoScriptBrowserTest.NoScriptPreviewsEnabledHttpRedirectToHttps

All browser_tests and content_browsertests pass on my Linux machine.

(Actually some tests are failing but these failures happen w/o S13nSW too).
 
Filed tracking bug for layout test failures ( issue 869302 ).

I'll re-open this if I find other failures on bots etc.
