Cypress Installation for Test Automation: Tutorial

Cypress is a purely JavaScript-based test automation tool for the modern web. As a testing tool, it is not just an alternative to Selenium WebDriver.

Cypress has been developed to introduce developers to software testing – something usually left to testers and QA professionals. It is built for the modern web and addresses the pain points devs and QA teams face while testing an application.

It supports different types of testing like:

• End to End Testing
• Unit Testing
• Integration Testing
• API Testing

That being said, this article will function as a tutorial on how to install Cypress and get started with test automation with two easy examples.

Getting Started with Cypress Installation

Cypress is a desktop application that users need to install in their systems. It supports the following operating systems:

• MacOS 10.9 and above (64-bit only)
• Windows 7 and above
• Linux Ubuntu 12.04 and above, Fedora 21, and Debian.

Prerequisites For Installing Cypress

One needs to have Node.js preinstalled in their systems as Cypress is a Node-based application. Node.js is a JavaScript runtime environment. One can download and install Node.js for a particular operating system from their download page. The Node.js installation also covers the installation of npm (Node package manager).

Cross verify the Node.js installation by running the command: node –version in the terminal. To verify the npm version, run the npm –version command.

A user must also have a code editor like Microsoft’s Visual Studio Code for convenient programming and maintaining project directories.

For users using npm to install Cypress, Cypress supports Node.js 10 and above.

How to Install Cypress?

There are two ways to install Cypress:

1. Using NPM

To install Cypress using the npm (Node package manager) navigate to the project directory and execute the following command:

npm init

The command above creates the package.json file. Just provide fundamental details like – package name, description, keywords, and author name.

The image below represents the final package.json file once the user fills up the details. Once done, run the command below to install Cypress.

npm install cypress --save-dev

The command above installs Cypress locally as a dev dependency for the particular project.

For users willing to install Cypress using the Yarn package manager, navigate to the project directory and execute the following command:

 yarn add cypress --dev

2. Downloading Cypress Directly

For users who are not acquainted with npm, yet want to try Cypress instantly, it is possible to directly download the zip file of Cypress from the CDN.

The direct download link automatically detects the user’s platform and fetches the zip file with the latest version of Cypress. Bear in mind that users who downloaded Cypress directly won’t be able to record the dashboard. Once the zip file is downloaded, unzip and double-click to start the Cypress application. It will start without the need for installing any dependencies.

Cypress installation is now complete.
