## Install & Run

### As Global NPM Package

```shell
npm install selenium-standalone -g
selenium-standalone install && selenium-standalone start
```

### As a Local NPM Package

```shell
npm install selenium-standalone --save-dev
npx selenium-standalone install && npx selenium-standalone start
```

### As a Docker Service

```shell
docker run -it -p 4444:4444 webdriverio/selenium-standalone
```

If you run Chrome or Firefox tests within a Docker container make sure you set capabilities so that the session is headless, e.g.:

```js
capabilities: {
  browserName: 'chrome',
  'goog:chromeOptions': {
    args: ['--no-sandbox', '--headless']
  }
}
```

or Firefox:

```js
capabilities: {
  browserName: 'firefox',
  'moz:firefoxOptions': {
    args: ['-headless']
  }
}
```

If you are looking for more sophisticated Docker container that allows you to run browser, check out the [Docker Selenium](https://github.com/SeleniumHQ/docker-selenium) project.
