Are you tired of the limitations in testing frameworks when working with Flutter? Patrol is here to rescue you! This simple yet powerful Flutter-first UI testing framework redefines the way we handle testing by overcoming the obstacles set by other packages like flutter_test, integration_test, and flutter_driver.

What is Patrol?

Patrol is meticulously crafted by LeanCode to streamline your Flutter testing. With its intuitive custom finders and native automation capabilities, you can build robust tests for your applications effectively.

To dive deeper into what Patrol has to offer, you can read more about it in our extensive documentation.

Getting Started with Patrol Custom Finders

What’s the fuss about Patrol’s custom finders? Let’s clarify it with a fun analogy. Imagine you’re at a gigantic bookstore. Traditional finders are like asking a librarian for help to locate that one elusive book you want—tedious and complex! However, with Patrol’s custom finders, it’s like having a magic map that directly guides you to your book in one step. Simple, isn’t it?

Using Custom Finders in Your Test

Here’s how you can transform your testing code from a lengthy routine to a breeze:

patrolTest(signs up, (PatrolIntegrationTester $) async {
    await $.pumpWidgetAndSettle(AwesomeApp());
    await $(#emailTextField).enterText(charlie@root.me);
    await $(#nameTextField).enterText(Charlie);
    await $(#passwordTextField).enterText(ny4ncat);
    await $(#termsCheckbox).tap();
    await $(#signUpButton).tap();
    await $(Welcome, Charlie!).waitUntilVisible();
});

Native Automation: Expanding Horizons

One of the primary limitations of the default integration_test is its inability to interact with the device OS. Think of it as reaching for a light switch in a dark room but being confined to your chair—frustrating! Patrol, however, provides the tools to break these limitations.

Example of Utilizing Native Automation

With Patrol, you can easily manage network conditions, system themes, and permission dialogs:

void main() {
    patrolTest(showtime, (PatrolIntegrationTester $) async {
        await $.pumpWidgetAndSettle(AwesomeApp());
        await $.native.enableCellular();
        await $.native.disableWifi();
        await $.native.enableDarkMode();
        await $.native.selectFineLocation();
        await $.native.grantPermissionWhenInUse();
        await $.native.openNotifications();
        await $.native.tapOnNotificationByIndex(0);
    });
}

Command Line Interface (CLI)

Don’t forget about the Patrol CLI! This tool greatly enhances the development speed of integration tests, especially when paired with features such as Hot Restart. You can still utilize flutter test for widget tests.

Troubleshooting Tips

If you run into any issues while using Patrol:

• Make sure your environment is correctly set up with Flutter’s latest version.
• Check the permissions in your device settings for native automation features.
• Consult Patrol’s documentation for error details or updates.
