# Getting Started with Applitools

Run your Cypress tests. A quickstart guide to running your Cypress tests across 30+ desktop browsers. Running your first Cypress test suite on BrowserStack is super easy - just install our CLI, configure the test run settings and start testing.

Back to Cypress blog. If you are a Node.js developer, installing Cypress as a dev dependency in your package.json file or even via direct download seems simple enough. Yet for developers working in other languages like Python or Go, using npm can be an obstacle. Cypress supports only Firefox, Chrome, Electron and headless browser. The support for Firefox is still under development. Selenium supports all major browsers like Firefox, Chrome, IE and Safari and so on. Cypress selectors include JQuery, css and some plugins for execution. When running cypress with options '-headless -browser firefox', cypress halts at the start of the second spec with message: Cypress could not connect to Firefox.

# Running Tests with Applitools

Prerequisites

A free Applitools account and Applitools API KEY

Tip: Unsure how to set up your API key?

Node.js https://nodejs.org
Git https://git-scm.com

Cypress Firefox Plugin

Note: Installing `git` is optional

Installing git is used to clone the demo project from the Github repository. Instead of installing git, you can simply download the Zip file from the repository. Further, if you are Mac, you already have git.

Google Chrome Browser https://www.google.com/chrome/

Cypress Firefox Iframe

# Running the Example Project

Clone or download the repository and navigate to that folder

Note: you can alternatively download the project as a Zip file and extract it

Install the dependencies

Set up Applitools Eyes

Run the example test

To run all of the tests in interactive mode, run:

Then click on the ultraFastGrid.spec.js test. The tests uses Chrome just once and sends the DOM snapshot to the Ultrafast Grid. The Grid will then render the DOM snapshot in the cloud. You need to wait 15-30 seconds.

To run all of the tests inside of the terminal, run:

TIP

The project additionally has a CI mode configured,which will run all of the tests inside of the terminalin headless mode. You can run this with: npm run test:ci

# Applitools Eyes Cypress SDK

Cypress Firefox Headless

# How it works

The Applitools Eyes Cypress SDK is a simple plugin to Cypress. Once installed, it adds few commands to the main cy object. Specifically, it adds three main methods, cy.eyesOpen to start the test, cy.eyesCheckWindow to take screenshots (for each test step) and cy.eyesClose to close the test.

Note: Supports Chrome, Firefox and Mobile simulators

The interesting thing is that even though you run your Cypress tests using Chrome browser, you can still add visual validations using both Chrome and Firefox! This is because we upload the DOM and assets to our Visual Grid that was rendered in Chrome and open it in Firefox or Chrome as per the settings. The same thing happens in mobile simulators as well.

The picture below shows how it works

You run the Cypress test as usual
Everytime you call cy.eyesCheckWindow, the SDK grabs the DOM and other assets asynchronously. And stores it locally until all the tests are done.
Once all the Cypress tests are done, the SDK uploads all the assets to the Visual Grid server
The Visual Grid server then opens up the assets in real browsers (Firefox or Chrome), or in mobile simulators, and with appropriate Viewport depending on what was set in the tests. Note that all these happen concurrently in the cloud.
As and when the rendering happens, the Applitools Eyes server gets notification about it and the eyes server then compares the pictures using AI and advanced algorithms and shows the results.
