Running the end-to-end tests on Windows

Windows is not the best platform to run the tests on, but if you have to, enable Windows Subsystem for Linux (WSL) and start following these steps to get going:

1. Navigate to your working directory (cd /mnt/c/users/travisr/whatever/matrix-react-sdk for example).
2. Run sudo apt-get install unzip python3 virtualenv dos2unix
3. Run dos2unix ./test/end-to-end-tests/*.sh ./test/end-to-end-tests/synapse/*.sh ./test/end-to-end-tests/element/*.sh
4. Install NodeJS for ubuntu:

   curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -
   sudo apt-get update
   sudo apt-get install nodejs
   

5. Run yarn link and yarn install for all layers from WSL if you haven't already. If you want to switch back to your Windows host after your tests then you'll need to re-run yarn install (and possibly yarn link) there too. Though, do note that you can access http://localhost:8080 in your Windows-based browser when running webpack in the WSL environment (it does not work the other way around, annoyingly).
6. In WSL, run yarn start at the element-web layer to get things going.
7. While that builds... Run:

   sudo apt-get install x11-apps
   wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
   sudo dpkg -i google-chrome-stable_current_amd64.deb
   sudo apt -f install
   

8. Get the IP of your host machine out of WSL: cat /etc/resolv.conf - use the nameserver IP.
9. Run:

   cd ./test/end-to-end-tests
   ./synapse/install.sh
   ./install.sh
   ./run.sh --app-url http://localhost:8080 --log-directory ./logs
   

Note that using yarn test:e2e probably won't work for you. You might also have to use the config.json from the element/config-template directory in order to actually succeed at the tests.

Also note that you'll have to use --no-sandbox otherwise Chrome will complain that there's no sandbox available. You could probably fix this with enough effort, or you could run a headless Chrome in the WSL container without a sandbox.
