Testing is a crucial part of the development process, ensuring that your code behaves as expected and helping to prevent bugs. Flutter provides a rich set of testing features to test apps at unit, widget, and integration levels.
1. Unit Testing π
Unit testing involves testing individual functions, methods, or classes. The test
package provides tools to write unit tests.
Setup:
Add the test
package to your pubspec.yaml
file:
Example:
2. Widget Testing π‘
Widget testing involves testing a single widget. The flutter_test
package provides tools to create widget tests.
Setup:
The flutter_test
package is included in every Flutter app.
Example:
3. Integration Testing π
Integration testing involves testing a complete app or a large part of an app.
Setup:
Add the integration_test
, and flutter_test
packages to your pubspec.yaml
file:
Example:
Complete Example Code π
Below is a simple Flutter app with corresponding unit, widget, and integration tests.
The app (lib/main.dart
):
lib/main.dart
):Unit Test (test/unit_test.dart
):
test/unit_test.dart
):Widget Test (test/widget_test.dart
):
test/widget_test.dart
):Integration Test (integration_test/app_test.dart
):
integration_test/app_test.dart
):In this example, you have a simple app with corresponding tests at unit, widget, and integration levels. This sets a good foundation for adding more complex tests as your app grows.
