Top Flutter Testing packages
Last updated: November 15, 2024
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.
