Utility on top of the [Flutter Driver API](https://api.flutter.dev/flutter/flutter_driver/flutter_driver-library.html) 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.
```yaml
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 `FlutterDriver`
Simply wrap your `FlutterDriver` tests with the method `capturePerformanceReport` to start collecting performance information
```dart
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.
```bash
$> 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`.
