Launch a visual editor from your Momentic project to build and debug tests against a live browser or mobile device. The local app runs on Windows, macOS, and Ubuntu and keeps your test files in your repository.

​
Launch the local app

Momentic distributes separate npm packages for browser and mobile testing. You can launch either editor with npx, without installing the package globally. Run the command from the directory that contains your momentic.config.yaml. The app command starts the local server and opens the GUI in your default browser. Use --config to load a config file from another location. The editor is cross-platform and supports Windows, macOS, and Ubuntu. Local iOS Simulator sessions still require macOS and Xcode, but you can use Momentic’s remote iOS simulators from any supported platform.

​
Edit tests interactively

Create tests and modules or open existing ones, then edit their settings and steps in the visual editor. Add, remove, duplicate, and reorder steps with drag and drop. Undo and redo changes while you shape the flow, then save the test as a readable YAML file in your project. You can run the full test or selected steps from the editor as you author. This keeps the live browser or device next to the test structure so you can confirm each interaction in context.

​
Debug browser and mobile runs

For browser runs, inspect screenshots, the current URL, console output, and network requests alongside the selected step. For mobile runs, inspect device screenshots and captured Android logcat or iOS syslog output when logging is enabled. The same run view lets you move between steps and compare the page or device state before and after an action.

​
Manage test settings

Manage test-level settings without editing YAML by hand. For browser tests, configure options such as the environment, viewport, retries, and browser behavior. For mobile tests, select app versions and devices, configure retries, and control device log capture. The editor writes these settings back to the test file so they remain versioned with the rest of your test suite.
