Although Appium is a great testing framework, it doesn't support the transition between the parts of the app that were created natively and those using Flutter. Therefore, if you have the OTP, push notifications, camera, or other native prompts in your customer journey, Patrol should be your default choice.

Will Patrol remain open source?

Patrol has been and always will be open-source, as we are strong proponents of the OS movement, and we believe that this is a pivotal part of the Flutter Enterprise ecosystem.

Will Patrol be maintained?

We are strongly committed to continuing further maintenance and development of Patrol as this is utilized in projects for our clients, and it is our obligation for them to bring new updates whenever necessary. Those projects and the user feedback inspire us to develop further, so you can be sure that investing your time in developing test scenarios with Patrol will prove right in the long run.

Automated UI Testing in Flutter

Automate QA processes in your Flutter application

Q: Can I integrate Patrol with popular Test Management Systems (TestRail, Allure, etc.)?

Yes, you can. Patrol is deeply integrated with native test tooling and supports the JUnit reporting format. It means you can easily export your test results to every popular test management system. It also doesn’t matter if you are making a Flutter-focused app and want to use Firebase Test Lab or if your company already utilizes Marathon Cloud and you’d like to stick with it - Patrol makes it possible.

Q: How can I be sure that the Patrol framework won’t be abandoned in the future?

At LeanCode, we use Patrol daily. We’ve built more than 30 Flutter apps for our clients over the past few years, and now Patrol is used by default for each new Flutter app we developed. Patrol is a very important part of our tech stack, and it guarantees it will be developed, updated, and bug-fixed in the future. We keep developing Patrol (the current version is Patrol 3.13) and adding new features.

Q: Can we just use Patrol on our own?

You can! We created Patrol as an open-source framework that is free to use. You can find more information about Patrol itself on the dedicated page.

Q: Is it possible to add a feature to Patrol that is dedicated to my case?

Our team can develop additional Patrol features dedicated to your app’s case. However, keep in mind that even if Patrol is a framework that is free to use, adding a feature is available only if you decide to use our automated UI testing service. We dedicate such possibility to business clients. Otherwise, you can share an idea on GitHub as a feature suggestion, and one day, we might put it on our roadmap.

Q: What languages should I use to write tests in Patrol?

Patrol was created with Flutter in mind and as the main target framework. Therefore, you can easily write your tests using Dart.

Automate Flutter app testing with Patrol

UI testing is crucial in mobile applications to ensure the app's quality, functionality, and great user experience. We 10x improved Flutter UI testing with our Patrol framework. Patrol overcomes the limitations of the existing solutions and is the only UI testing framework that works with both Flutter and native UI.

When do you need automated UI tests?

The growth of the mobile app

As your Flutter application grows, manual testing becomes more tedious and time-consuming. Once written, automated UI tests (UI test scripts) can be run in less time and without or with minimal human supervision. The cost of maintaining and executing those tests is far lower than manual testing and regression. Additionally, the QA team's saved time can be spent, e.g., on exploratory testing and other tasks that can’t be automated.

Release the mobile app to production

Each time you release your mobile app to production, you have to test new features and all the existing things developed so far. A big-picture view of what we created is very important, and no other tests do it better than UI tests. Our scenarios are on such a level of detail that they can correspond with features, and test suites can comply with the app's modules. Developers can utilize reports of such tests to monitor the system's health.

Ubiquitous regression

When ubiquitous regression becomes problematic, the development speed slows, and the release schedule becomes less predictable. UI tests help in regression tests because regression suites are precisely defined. There is no need to alter the test cases. This means an automated test can do the same task as a human tester and is faster, adding even more accuracy and repeatability in execution.

Critical User Flows

Automated UI tests ensure that key user interactions, such as transactions, logins, or other crucial app features, provide a smooth user experience. At LeanCode, we created Patrol with Flutter development teams in mind, who need a simple yet powerful and extensible tool for making the most challenging automated tests to ensure that the app functions correctly regardless of size.

Need an alternative to Appium

There are solutions popular in the native development world that can be integrated with Flutter. The most popular is Appium, a cross-platform UI testing framework. Although Appium does not have official support for Flutter, it does have an open-source connector with Flutter. Technically, it allows access to native and Flutter components, but using Flutter is extremely inconvenient and risky due to the lack of support for the provided connector. Our Patrol framework can be a great alternative to Appium.

We’ve built our own Flutter UI testing framework, Patrol. It overcomes the limitations of the existing solutions. Patrol is the only UI Testing Framework that works with both Flutter and native UI.
