1. Simply use flutter test command.
2. More to see https://flutter.dev/docs/cookbook/testing/unit/introduction
3. Package test usage: https://pub.dev/packages/test

1. An JS wrapper of dart unit test framework.
2. Similar to jest framework usage.
3. Support most jest framework apis: describe, it, beforeEach, afterEach, beforeAll, afterAll.
4. Support async operation by return a promise object from it.

1. We use flutter integration test to inject a running app.dart.
2. Each js file in fixtures is a test case payload.
3. Each case executed in serial.
4. app_test.dart will drive app.dart to run the test.
5. Compare detection screenshot content.
6. More to see https://flutter.dev/docs/cookbook/testing/integration/introduction

The easist way is copy test case from wpt.

You also write test case script if wpt is not suitable.

1. Create typescript file in specs folder.
2. Use describe and it to write test case like jasmine.
3. Use snapshot() at the end of it to assert.

Tips:

1. You can use xit to skip current test or fit to focus current test.
2. Every snapshot file is stored at snapshots folder. Plases commit those file.
3. You can use WEBF_TEST_FILTER shell env to filter test to run. Like WEBF_TEST_FILTER="foo" npm run integration.

• intergration test: npm run test

Use the following commands to switch your GPU into Intel's integration GPU.

sudo pmset -a gpuswitch 0

• 0: Intel's GPU only
• 1: AMD GPU only
• 2: dynamic switch

this above command will execute which spec's name contains "synthesized-baseline-flexbox-001"

 WEBF_TEST_FILTER="synthesized-baseline-flexbox-001" npm run integration
