-// This class of BrowserTests is a helper to create tests related to crashes in
-// Chrome Apps. To be tested, the app will have to be placed as any other test
-// app (see PlatformAppBrowserTest) and will need to send a "Done" message back.
-// When the "Done" message is received, the test succeed. If it is not, it is
-// assumed that Chrome has crashed and the test will anyway fail.

-// The entry in this file should be something like:
