Loading Webpages Timeouts in Test for Mash

Project Member Reported by jonr...@chromium.org, Aug 3 2017 
When running mash_browser_tests there are often timeouts of the entire suite.

This can be seen with test cases, such as BrowserTest.*, hitting the output timeouts of base/test/launcher/test_launcher.cc. This is a hard cap of 15s, and local testing showed these sometimes block for 25s.

While the tests do eventually pass successfully, on trybots they take so long that the test suite times out.

In the case of BrowserTest.* they eventually call ui_test_utils::NavigateToURLBlockUntilNavigationsComplete which then blocks for far too long

Trace of the first 30s of --mash startup.
Once the New Tab page opened up I clicked on an existing link within it to load twitter.com
After the page loaded i waited a bit, then closed the browser window.

+chiniforooshan@ I'm not sure what the current status of tracing is, and if a variant can be ran locally which could let us generate a trace to track down where page loading is slow.

Thoughts?

Can you please try to first cherry pick https://chromium-review.googlesource.com/c/chromium/src/+/575716 and then cherry pick https://chromium-review.googlesource.com/c/chromium/src/+/643747 and then capture a trace? Thanks!

Hey James,

I just noticed this issue in my backlog, I'm not sure if it's even valid anymore. Have you been seeing timeout issues with mash_browser_tests at all lately?

I haven't seen timeouts recently.
