[testing_app] Update and fix the testing app #2334
Description
- Does not follow guidance for where to place the test driver file. integration_test documentation and Flutter documentation suggest that the test driver should be under
test_driver/integration_test.dart. - Readme does not provide documentation for how to run integration tests for the Web (e.g. adding
-d [web-server | chrome]and startingchromedriver). - Running a simple integration test on chrome fails with opaque message
flutter drive \ --driver=integration_test/driver.dart \ --target=integration_test/app_test.dart \ -d chrome ... Rejecting promise with error: TypeError: Cannot read properties of undefined (reading 'group') - Missing examples of benchmark testing
- Open question: I could not tell from looking at the code. Are integration tests ran on the Flutter CI? Are they ran on web on the CI?
- Investigate
testing_apphangs on Windows #1000, close if its no longer an issue.
