`CAPYBARA_SERVER_PORT`: configure server port
78 78 
`SELENIUM_REMOTE_URL`: remote Selenium URL
79 79 
`CAPYBARA_APP_HOST`: by default, the tests expect to have the application running on your localhost. Using this variable, you can set a custom URL
80 
`GOOGLE_CHROME_OPTS_ARGS`: configure Google Chrome Options arguments as a comma-delimited string. For example, it can be used to run the tests in headless mode:
81 
    `export GOOGLE_CHROME_OPTS_ARGS="headless,disable-gpu,no-sandbox,disable-dev-shm-usage"`

One use case of these variables is to run the system tests on a remote Selenium/ChromeDriver (eg: Docker).
