# Configuration

This helper should be configured in codecept.conf.ts or codecept.conf.js

# Example #1: Show chrome browser window

{
   helpers: {
     TestCafe : {
       url: "http://localhost",
       waitForTimeout: 15000,
       show: true,
       browser: "chrome"
     }
   }
}

To use remote device you can provide 'remote' as browser parameter this will display a link with QR Code See https://devexpress.github.io/testcafe/documentation/recipes/test-on-remote-computers-and-mobile-devices.html (opens new window)

# Example #2: Remote browser connection

{
   helpers: {
     TestCafe : {
       url: "http://localhost",
       waitForTimeout: 15000,
       browser: "remote"
     }
   }
}
