Automate testing of a web app developed with FlutterFlow is often complex because it employs shadow DOM as a technique for rendering the UI. This technique makes it challenging to find elements and then be able to engage with them, and hence attempts at automating the app with traditional Selenium, Playwright, and other open-source tools become complicated.

What is Flutter Flow?

FlutterFlow is an interface through which you design and create mobile applications using Google’s Flutter framework. 

It offers a no-code/low-code solution, for creating and designing native iOS and Android Flutter applications, without requiring you to write large volumes of code. Using FlutterFlow, you can design the UIs, link the data and even implement additional features using code.

Can We Automate Tests for Flutterflow Apps?

The short answer is yes, but there is a lot of engineering involved!

Flutterflow is an advanced tool for designing good-looking mobile apps with the help of which you don’t have to write a single line of code. But when it comes to the aspect of automating the Flutterflow app, the issue becomes a question of identifying the DOM elements on the Web Pages produced by Flutterflow. 

This is because Flutter Flow uses either the “canvaskit” or the “html” web renderer to build the interface of the application, so the elements are either drawn on one canvas and then painted in order or are built from the custom HTML tags. 

Considering this, FlutterFlow DOM elements are hard to discover and even interact with using standard testing tools and frameworks.

Solution?

There are specific difficulties in automating tests for the Flutterflow apps, especially when it comes to finding and manipulating DOM elements of the web pages built with Flutterflow. 

However, overcoming these hurdles is a challenge, which being a leading QA company we have achieved by implementing the best tools and techniques. Curious to know how we did it?

Frequently Asked Questions

What are the prerequisites for testing a FlutterFlow-made app on mobile devices?
FAQ ArrowFAQ Minus Arrow

To test on mobile devices, you need to be on a paid FlutterFlow plan to download the code. For iOS, you’ll need a Mac with Xcode, and for Android, any machine (Windows, Mac, or Linux) with the appropriate SDKs installed.

How can I test my FlutterFlow app on a real device?
FAQ ArrowFAQ Minus Arrow

You can test your app on a real device using the Local Run feature in the FlutterFlow Desktop app, which tracks changes in your project and allows you to see updates instantly on a device. Alternatively, you can manually download the code and run it in your preferred IDE.

Are there automated tests available for FlutterFlow apps, and how do they work?
FAQ ArrowFAQ Minus Arrow

FlutterFlow supports creating automated tests for your projects, which are crucial for ensuring that the app’s features work as expected without human intervention. These tests are based on the Flutter integration testing framework and can be run locally or through services like Firebase Test Lab. However, running tests directly on the FlutterFlow platform is not yet supported.

How do I handle testing for native functionalities that can’t be tested in a browser?
FAQ ArrowFAQ Minus Arrow

Native functionalities like camera access or push notifications should be tested on actual devices or emulators. This ensures that these features work as intended in real-world scenarios, which is crucial before deploying your app into production.
