Requires testcafe package to be installed.

npm i testcafe --save-dev

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

{
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

{
helpers: {
TestCafe : {
url: "http://localhost",

}
}
}

Call Testcafe methods directly using the testcafe controller.

const comboBox = Selector('.combo-box');
await testcafeTestController
.hover(comboBox) // hover over combo box
.click('#i-prefer-both') // click some other element
