Enable developers to validate Dart and Flutter code correctness through well-structured unit tests.
Create a test file under test/ that mirrors your lib/ directory, then run dart test to execute the suite.
High-intent search queries and answers about installing and using this skill.
Structure Dart unit tests by creating files under the test/ directory that mirror your lib/ organization to improve discoverability. Use group to organize related tests, setUp and tearDown for shared state, and expect for assertions.
Yes, you can integrate Mockito for mocking dependencies and defining expectations in Flutter unit tests. This Skill supports mocked scenarios, allowing you to isolate components and validate behavior using package:test.
Yes, this unit testing approach fully supports asynchronous Dart code testing. You can validate synchronous, asynchronous, and mocked scenarios across pure Dart and Flutter projects using package:test.
The best way to organize related Dart tests is using the group function provided by package:test. Combine this with setUp and tearDown methods to manage shared state and ensure clean, well-structured test suites.
After organizing your files under the test/ directory to mirror your lib/ structure, run the dart test command to execute your entire Dart unit test suite and validate code correctness.
