Frequently Asked Questions about dart-test-fundamentals

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure Dart tests using groups and test functions?▼

Structure Dart tests using the `group` function to organize related tests and the `test` function to define individual cases. This creates a clear, maintainable hierarchy for your Dart testing suite.

What do setUp and tearDown do in a Dart test suite?▼

`setUp` and `tearDown` manage test lifecycles by running code before and after each test. `setUpAll` and `tearDownAll` execute once for the entire group, ensuring a clean testing environment.

How do I configure Dart test execution for specific platforms and timeouts?▼

Configure Dart test execution by creating a `dart_test.yaml` file. This configuration file allows you to specify target platforms, define custom timeouts, and tag tests to control how they run.

Can I use package:test for testing Flutter applications?▼

Yes, `package:test` is the underlying framework for Flutter testing. Mastering its core concepts like test grouping and lifecycle management is essential for writing reliable tests for both Dart and Flutter applications.

What is the best way to start writing a unit test for a Dart file?▼

To start writing a unit test, use the dart-test-fundamentals skill to generate a new test file for your feature. It guides you in applying `package:test` best practices for robust test structuring.

When should I use dart_test.yaml instead of inline test configurations?▼

Use `dart_test.yaml` when you need to configure test execution globally across your Dart project. It centralizes platform targets, tags, and timeout settings, preventing repetitive inline configurations.
