[versions] update all versions and fix tool tests (#60127)
Update all versions, specifically file which fixes some bugs that caused tests to fail if run in different orders:

- systemTemp directories created by MemoryFileSystem will allot names based on the file system instance instead of globally.
- MemoryFile.readAsLines()/readAsLinesSync() no longer treat a final newline in the file as the start of a new, empty line.
- RecordingFile.readAsLine()/readAsLinesSync() now always record a final newline.

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 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.
