// A base class for browser tests run on Android. It exposes very little API
// since the majority of the Android UI is accessed through static methods,
// such as TabModelList.
//
// Do *not* extend this class to attempt to mirror APIs on InProcessBrowserTest
// which is the base class for desktop platforms.
// Shared abstractions around Desktop-vs-Android should be implemented as
// topical helper classes or functions independent of the BrowserTestBase class
// hierarchy. Helpers may take a PlatformBrowserTest* in their APIs in order to
// support both types of browser tests, such as in the chrome_test_utils
// namespace.
//
// Further details and methodology can be found in the design doc:
// https://docs.google.com/document/d/1jT3W6VnVI4b0FuiNbYzgGZPxIOUZmppUZZwi3OebvVE/preview
