Testing
Top Flutter Testing packages There are many ways to test a Flutter app, but some common methods include: * **Unit testing**: Unit tests focus on small pieces of code, or units, to ensure that they are working as expected. * **Widget testing**: Widget tests (or component tests) focus on testing a single widget at a time. The goal of a widget testing is to verify that the widget's UI looks and interacts as expected. * **Integration testing**: Itegration tests check how well units work together in an app. * **User testing**: User tests simulate how real users would interact with the app given in form of a user interaction workflow. Testing can either be done manually or using automated tools. The complete list of Dart and Flutter packages given below provide tools/frameworks to perform Testing, Mock Testing, Widget Testing, UI Testing, etc. and also publish Coverage reports.
