Bug 32038 – http/tests/cache/subresource-failover-to-network.html is Flaky on Windows

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Brian Weinstein]

This test is flaky on Windows, and has been since it was first added to the repository. All of the loads appear to be happening, but sometimes:

http://127.0.0.1:8000/cache/resources/subresource-failover-to-network.cgi - didFinishLoading

Happens before:

main frame - didFinishDocumentLoadForFrame
main frame - didHandleOnloadEventsForFrame
main frame - didFinishLoadForFrame

Instead of after.

Here is a log of the test in the way it fails:

This test is also flaky for the chromium bots:

Added to Windows Skipped list in r51611, make sure to take it off when the test is deflakified.
