### Running in a browser
Since we see that Chrome and Firefox browsers are pre-installed in the container, let's run tests using Firefox for example
```shell
$ ./cy-run.sh --browser firefox
```
## Cypress open
Follow [Running GUI applications using Docker for Mac](https://sourabhbajaj.com/blog/2017/02/07/gui-applications-docker-mac/) and install [XQuartz](https://www.xquartz.org) X11 server. Then see [cy-open.sh](cy-open.sh) for Docker run command that forwards XVFB events from Cypress to the X11 server running on the host machine. You should see Cypress Test Runner open and work fine.
## Cypress plugins
If your project uses [Cypress plugins](https://on.cypress.io/plugins) and they are declared inside [package.json](./package.json) file, then they should be installed before launching Cypress using Docker. For example this project uses [cypress-axe](https://github.com/component-driven/cypress-axe) plugin.
Before running the tests
```shell
npm install
./cy-run.sh
```
Note: if any plugins use native extensions, they would need to be installed under exactly the same environment as the Cypress included Docker image that runs them.
