The testWidgets function allows you to define a widget test and creates a WidgetTester to work with. This test verifies that MyWidget displays a given title and message.

Widget testing A catalog of recipes for adding widget testing to your Flutter app.

Check app functionality with an integration test Learn how to write integration tests

The goal of a widget test is to verify that the widget's UI looks and interacts as expected. Testing a widget involves multiple classes and requires a test environment that provides the appropriate widget lifecycle context.

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:

Animate a widget using a physics simulation Learn how to move a widget from a dragged point back to the center using a spring simulation.

These tests allow you to test the Dart portion of your plugin just as you would test the Dart code of a non plugin package. However, the plugin's native code won't be loaded, so any calls to platform channels need to be mocked in tests.

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.

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.

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.
