The build process will watch for changes to the filesystem, rebuild and autoreload the editor. However note this from the webpack-dev-server docs
> webpack uses the file system to get notified of file changes. In some cases this does not work. For example, when using Network File System (NFS). Vagrant also has a lot of problems with this.
Snippet from <https://webpack.js.org/configuration/dev-server/#devserver-watchoptions->
To enable polling add `export WEBPACK_DEV_SERVER_POLLING=1` to your enviroment.
For testing we use [webdriverio](http://webdriver.io) and [selenium-standalone](https://github.com/vvo/selenium-standalone)
[selenium-standalone](https://github.com/vvo/selenium-standalone) starts a server that will launch browsers on your local machine. We use chrome so you **must** have chrome installed on your machine. Now open and terminal and run
```
./node_modules/.bin/selenium-standalone
```
Then open another terminal and run
```
npm test
```
After some time you should see a browser launch which will be automated by the test runner.
