There’s no limit to testing in Unity

Our tools make test automation accessible for Unity games and apps by allowing teams to inspect and programmatically control the objects of their application. The result? Fast feedback after every commit!

How it works

1. Instrument your game to support end-to-end test automation

  • Connect your instrumented game/app and tests to a local or remote server started in AltTester® Desktop to identify and interact with Unity objects
  • Simulate any kind of device input (support for Input Manager and Input System)
  • Use and modify any methods and properties

2. Inspect the game objects hierarchy and get all the properties easily

  • Get object’s components, assemblies, methods, fields and properties without accessing the source code
  • Get selectors and validate them before running your tests
  • Interact with your game from AltTester® Desktop using keyboard, mouse, touchscreen and joystick actions
  • Load any scene or level
  • Control the speed of the game for debugging and test design purposes

3. Record steps to generate automated tests faster

  • Record actions on screenshot area (select, click, press key)
  • See code displayed based on the recorded actions (the clicked objects will be identified using full path)
  • Assert properties to certain values
  • Copy the generated code to your test file where you can edit and run it

4. Run automated tests on real devices: PC, Mobile, WebGL, Console

  • Write tests in C#, Python, Java or Robot Framework, using any popular test framework
  • Run tests concurrently on different devices
  • Integrate with Appium, device cloud services like BrowserStack, Bitbar, AWS Device Farm, or SauceLabs
  • Include screenshots in your test reports

We helped 5000+ users to test their games and we’re proud of their feedback.

“It is the best tool for unity applications. It is very simple and easy to implement as it is a bit similar to appium. Inspecting and performing actions on elements are very easy. Updates on the tools are stable and moreover the support and response from this team is very good as I have been using this since 10 months for my project. Thanks for the altom team for the this asset”
