This logic was used to satisfy
TEST_F(GoogleAppsSettingsCollectionViewControllerTest, AppDidInstall)

[sdefresne, 2016/11/28 09:28:12]

This can probably be changed to the following:

return url.is_valid() && url.SchemeIs(base::SysNSStringToUTF8(_appName));

[sczs1, 2016/11/28 19:16:30]

An invalid url needs to return yes all the time. Which won't be the case if we
use that condition.

+  if (!url.is_valid())
+    return YES;
+  GURL appUrl(base::SysNSStringToUTF8(_appName) + ":");
+  if (url.spec() == appUrl.spec()) {
+    return YES;
+  } else {
+    return NO;
