While trying to enable webview sign-in by default, I found a bunch of issues

If none of the tests are for ChromeOS, can this file maybe be excluded
altogether in the .gyp file?
Also: does this bubble exist on android/ios?

[Roger Tawa OOO till Jul 10th, 2015/01/05 20:19:19]

Done.
Android already handled in gyp file in previous patchset.
ios does not use the gyp variable "chrome_browser_tests_sources" that includes
this source file.
