Testing and Mocking Dart Applications Contents Structuring Code for Testability Managing Dependencies Generating Mocks Implementing Unit Tests Workflow: Creating and Running Mocked Tests Examples Structuring Code for Testability Design Dart classes to support dependency injection. Isolate complex external dependencies (like API clients or databases) so they can be replaced with mock objects during testing. Inject external services (e.g., http.Client) through class constructors. Represent URLs strictly as Uri objects using Uri.parse(string). Utilize Dart's object-oriented features (classes, mixins) to define clear interfaces for external interactions. Managing Dependencies Configure the pubspec.yaml file with the necessary testing and code generation packages.
