Protected: Patrol
Writing Your First Patrol Test Case
Writing your first Patrol test case is an important milestone. In this lesson, we will explore how to write effective test cases, interact with UI elements, and use assertions to verify test outcomes.
Understanding Test Case Structure
Each Patrol test case consists of:
- Test Setup: Initializing the app and defining the test scope.
- Interactions: Tapping buttons, entering text, swiping, etc.
- Assertions: Verifying if actions produce the expected result.
Writing Your First Test Case
patrolTest('Check Login Button', (Patrol patrol) {
patrol.driver.tap(find.byType(LoginButton));
patrol.driver.enterText(find.byType(PasswordField), 'password123');
patrol.driver.tap(find.text('Submit'));
patrol.driver.waitFor(find.text('Welcome'), timeout: Duration(seconds: 5));
});
Using Assertions
Assertions help you validate that the correct UI elements appear after performing actions:
expect(patrol.driver.find.byType(HomeScreen), isPresent);
Conclusion
Now that you have written your first Patrol test case, you can start testing various scenarios. In the next lesson, we’ll look into organizing test suites for multiple scenarios.
