Manual Tests

We try to automate as much as possible, but particularly for frontend changes it is usually necessary to verify work with a manual test. When manually testing a feature, it's useful to check:

  • Does the UI look consistent across different desktop browsers?
  • Is the UI optimised for a mobile layout?
  • Does the feature behave consistently across desktop and mobile browsers?
  • Is the feature accessible? (See the Accessibility testing docs)

Tips for testing on mobile

For features involving touch interactions it becomes more important to test on actual mobile devices, rather than using the browser dev-tools device simulator. There can be some platform-specific differences in how these touch events are handled and it's useful to make sure a feature is checked on both android and iOS.

One way to run your development code on your own mobile device is to use ngrok. ngrok is a free tool that allows you to access your localhost:3000 via a standard URL. To use it:

  • Follow ngrok's instructions to download/install the tool (there is a free tier)
  • Run ngrok http 3000 in your terminal
  • Copy the URL given in response (e.g. and add it to your .env file's APP_DOMAIN value (replacing localhost:3000)
  • Start the app via bin/startup as usual
  • Visit the ngrok URL on your mobile (to save copying the text, you could use a QR code generator on your desktop browser so you only need to point your camera at the screen)
