Tap, drag, and enter text - Flutter
Many widgets not only display information, but also respond to user interaction. This includes buttons that can be tapped, and TextField for entering text. To test these interactions, you need a way to simulate them in the test environment. For this purpose, use the WidgetTester library.
Find widgets - Flutter
The find constant provided by the flutter_test package provides several ways to locate widgets in the test environment. This recipe demonstrated three of these methods, and several more methods exist for different purposes.
Check app functionality with an integration test | Flutter
The integration_test package lets you: Use the flutter drive command to run tests on a physical device or emulator. Run on Firebase Test Lab, to automate testing on a variety of devices. Use flutter_test APIs to write tests in a style similar to widget tests.
Handle scrolling - Flutter
To scroll through lists via integration tests, use the methods provided by the WidgetTester class, which is included in the flutter_test package: In this recipe, learn how to scroll through a list of items to verify a specific widget is being displayed, and the pros and cons of different approaches.
Introduction | Flutter
The test package provides the core framework for writing unit tests, and the flutter_test package provides additional utilities for testing widgets. This recipe demonstrates the core features provided by the test package using the following steps:
Material component widgets - Flutter
