[WIP] An integrated development environment for Selenium scripts


This project is a work in progress, a complete rewrite of the old Selenium IDE. The older IDE was a Firefox extension that relied heavily on APIs that are no longer supported by newer versions of Firefox. In this project, the IDE is developed as a modern browser extension, supporting both Chrome and Firefox and other modern browsers (in theory).

As this is an early stage and many things aren't clear, it's quite challenging to collaborate and coordinate the efforts - so please be patient.

We are using SideeX as a start point. The SideeX team was kind enough to let us use their work.




  • git has to be in $PATH for the installation to pass

  • yarn npm might work as well (untested)

  • peru


peru requires a POSIX machine to work, for the time being you can only properly build the extension on macOS and Linux.

  • Install the dependencies peru sync
    yarn or if using Node 10 yarn --ignore-engines
  • Build the extension
    yarn build and then yarn build:webdriver and then yarn build:ext:prod or yarn build:ext for faster development build (also includes beta features)
  • Install as developer on Google Chrome or Firefox

What now?

Here's a draft of the general tasks ahead. Feel free to pitch in and announce which you wish to take upon yourself:

  • Extension UI - SeIDE users should feel right at home
  • Selectors accuracy - an option is ranking selectors - we can optimize selectors correctness and test stability by collecting as many attributes as we can per user event. The most likely properties will be used for the selectors, with fallback to the others.
  • Intelligent editing
  • Export to selenium code in different languages
  • Playback in a way that's consistent with web drivers
  • Open for extensions
