Very Good Performance
Developed with
Utility on top of the Flutter Driver API that facilitates measuring the performance of your app in an automated way
Usage
very_good_performance.yaml
Add a new file at root of your project named very_good_performance.yaml with the following fields.
You can modify these values to match your own performance expectations.
performance_report:
directory: performance/reports
integration_test_expectations:
should_fail_build_on_warning: true
should_fail_build_on_error: true
performance_metrics:
missed_frames_threshold:
warning: 5
error: 10
average_frame_build_rate_threshold:
warning_time_in_milliseconds: 14.0
error_time_in_milliseconds: 16.0
worst_frame_build_rate_threshold:
warning_time_in_milliseconds: 14.0
error_time_in_milliseconds: 16.0
Running tests with FlutterDrive
Simply wrap your FlutterDriver tests with the method capturePerformanceReport to start collecting performance information
test('tapping on the Increment button updates the counter', () async {
await driver.capturePerformanceReport(
reportName: 'counter_performance',
action: () async {
await driver.tap(find.byType(FloatingActionButton));
expect(await driver.getText(find.text('1')), '1');
await driver.tap(find.byType(FloatingActionButton));
expect(await driver.getText(find.text('2')), '2');
},
);
});
At the end of the execution, you will see a similar report to this one:
Running the example project
You can find an example project that showcases how to use this library.
$> cd example
$> flutter drive --target=e2e/e2e.dart --driver=e2e/counter_test.dart -d macos --profile
You should see the Counter app running and, at the end of the execution, it will print the performance overview in the console, and will generate the performance reports under e2e/performance/reports.
