# Summary This tests contains an app with a main page and sub pages. The main page contains a list of buttons; each button leads to a designated sub page when tapped on. Each sub page should displays some simple UIs to screenshot tested. The flutter driver test runs the app and opens each page to take a screenshot. Use `main_test.dart` to test against golden files stored on Flutter Gold. Note that new binaries can't be checked in the Flutter repo, so use [Flutter Gold](https://github.com/flutter/flutter/wiki/Writing-a-golden-file-test-for-package:flutter) instead. # Add a new page to test 1. Create a new class which extends `Page` and implement the UI to be tested in the `build` method. 2. The new class should set a static `title` and `key` 3. Add an instance of the new class to the `_allPages` list in the `main.dart` 4. Create a new test case similar to `"'A page with an image screenshot"` in `test_driver/main_test.dart` to run the screenshot test. An example of a `Page` subclass can be found in `lib/image_page.dart` # Environments * Device Lab which runs the app on iPhone 6s. * LUCI which runs the app on a Fuchsia NUC device.
