Introducing the Power Apps Test Engine: Enhancing Testing Capabilities for Power Apps

The Power Apps Test Engine is a remarkable component within the Microsoft Power Platform Command Line Interface (PAC CLI). It’s specifically designed for testing standalone canvas apps in Power Apps. To utilize the Test Engine, users must first install the Microsoft Power Platform CLI. This innovative tool promises to significantly elevate the testing experience within Power Apps, ensuring more robust applications with fewer bugs and higher performance standards.
Preview Feature Notice
The Power Apps Test Engine is currently a preview feature. Preview features are not intended for production use and may have restricted functionalities. These features are offered to customers before an official release to provide early access and gather valuable feedback. Users should be aware that preview features are subject to supplemental terms of use.
Benefits of Power Apps Test Engine
The Power Apps Test Engine boasts several compelling benefits that make it a valuable addition to the Power Apps ecosystem.
Power Fx Test Authoring
The Test Engine allows users to author tests in the YAML format using the familiar Power Fx language. This compatibility with Power Fx ensures a seamless and intuitive testing experience, enabling users to leverage their existing knowledge and expertise in app development.
DOM Abstraction
Users can reference control names defined within Power Apps Studio while authoring tests, eliminating the need to use JavaScript or be familiar with the browser Document Object Model (DOM) rendered output of the app. This abstraction simplifies the testing process and makes it more accessible to users who may not have advanced technical skills.
Connector Mocking
The Test Engine supports the creation of mocks for network calls made by the app using connectors. This feature enables users to test apps without modifying them and avoids unwanted side effects from external APIs. Connector mocking ensures that tests are more accurate and reliable, reflecting the true functionality of the app without external interference.
Screenshot and Video Recording Support
One of the standout features of the Test Engine is its ability to take screenshots and record videos of test runs. These visual aids are invaluable for diagnosing failed tests and understanding the actual experience of failed test cases. Screenshots and recordings provide clear evidence of issues, facilitating quicker and more effective troubleshooting.
