The CSS regression covers pages by taking and comparing pictures, thus it checks if the elements are different of what they suppose to be for the end user in different browsers and resolutions.
The package is a wrap of another package called differencify which can be reached here: https://github.com/NimaSoroush/differencify/
npm install --save css-regression
// Import
const regression = require("css-regression")
// Take pictures of all devices listed
const css = () => {
// Take pictures for all pre-defined devices
regression.queueAll("<url to be defined>")
// Execute
regression.execute()
}
css()
