Cypress Automation: 15 Important Factors Related To It

In this tutorial, we will discuss the Cypress Automation Framework in detail. We will be covering what Cypress is, how it is different from other testing frameworks, the architecture of Cypress, and the installation procedure in this article. Cypress is an exciting topic and is fun to learn too. Let’s begin!

Cypress Automation Framework

Cypress Automation Framework is a pure Javascript-based testing tool that mainly focuses on front-end testing in modern web applications. With Cypress, applications are easy to test with the visual interface to witness the test execution. Thus, Cypress comes as a boon for both developers and QA engineers by making script writing and test execution easy. In addition, it comes with a distinctive test runner, which makes DOM manipulation easy and runs directly on the Browser.

What is Cypress?

Cypress is faster, better and provides definitive testing that runs on a browser.Cypress is mainly compared with Selenium, but it is completely different. Cypress does not run on top of Selenium, which means it is completely independent. Instead, Cypress runs on top of Mocha, which is again a Javascript-rich test framework. It is compatible with only the Chai Assertion Library, which can access a wide range of BDD and TDD assertions.

Cypress mainly focuses on three different types of testing. They are End-to-End tests, Unit tests, and Integration tests. Cypress can execute any tests that can run in a browser. In addition, it comes along with different mocking capabilities and validations that are enthralled towards front-end testing.

The browsers that Cypress supports are Chrome, Firefox, Edge, Electron, and Brave. Moreover, cross-browser testing is easily achievable with Cypress. Finally, though Cypress supports only Javascript, it can also be written with Typescript, primarily written with Javascript.

Cypress Automation

Cypress is an open-source tool with a free Test runner but has pricing ranging for teams and businesses where they charge you for the Dashboard. However, Dashboard is free up to some extent, unless you additional features like Flake detection, Email support, Jira integration, and many more.

Cypress is mainly used to automate scripts on the web(can automate anything that runs on a browser). It can never run on native mobile apps but can automate some of the functionalities of the mobile applications if those are developed in a browser.


There are many awesome features available in Cypress that stand out from any other automation tool. Here, let’s discuss some of the main features, and we’ll get introduced to other parts later once we begin writing our test cases!

  1. Automatic waiting – Cypress has the advantage of automatic waiting. We will never need to add force waits and sleeps for waiting for the DOM to fetch the element. Cypress automatically waits for any interaction with elements and execution of assertions. Thus, tests are fast!
  2. Time travel – Cypress captures screenshots during test execution. We can view the results visually in real-time by just hovering on the executed commands in the Dashboard. This way, the tests are easier to debug
  3. Debugging tests – Cypress can debug tests from popular tools like Developer tools. The errors are readable, and stacks are easily traceable.
  4. Stub requests – Cypress has options to confirm and control function behaviors, network responses, or timers used by stubs and spies.
  5. Continuous Integration – Cypress does not depend on any other additional CI services. However, on running the command for the test, integration is easily accessible.

Myth about Cypress

There is a myth that Cypress can run only on Javascript-friendly web applications. However, Cypress can test any web applications built with Django, Ruby on Rails, Laravel, etc. In addition, Cypress supports any of the programming languages such as PHP, Python, Ruby, C#, etc. However, we write our tests in Javascript; beyond that, Cypress works on any application.

Components of Cypress

There are two main components in Cypress. They are Test Runner and Dashboard.

Cypress Test Runner

Cypress Test Feature

Test Runner – Cypress provides this unique test runner, where the user can view the commands during execution and application under test.

There are few subcomponents under Test runner. They are

  1. Command Log – This is a visual representation of the test suite. You can see the commands executed in the test, the assertion details, and the test blocks.
  2. Test Status menu – This menu shows the number of test cases that passed or failed and the time taken for execution.
  3. URL Preview – This gives you information about the URL you are testing to keep track of all the URL paths.
  4. Viewport sizing – You can set the app’s viewport size for testing different responsive layouts
  5. App Preview – This section displays the commands that run in real-time. Here you can use Devtools to debug or inspect each base.

Dashboard: Cypress Dashboard gives the ability to access the tests that are being recorded. With Dashboard service, we can witness the number of passed, failed, or skipped tests. Also, we can view snapshots of the failed tests by using cy. screenshot() command. You can also witness the video of the entire test or the clip of the failed tests.

Cypress Architecture

Most of the testing tools run on the server outside the Browser and execute commands over the network. But, Cypress runs on the Browser where the application is also running. This way, it can access all the DOM elements and everything inside the Browser.

Node server runs behind the Cypress on the client-side. Thus, the node server and Cypress interact with each other, accompany and carry out tasks to support the execution. Since it has access to both the front and back end, the responsiveness to the application in real-time during execution is well accomplished and can also perform tasks that even run outside the Browser.

Cypress also interacts with the network layer and captures commands by reading and changing the web traffic. Finally, Cypress sends HTTP requests and responses from the node server to the Browser. Since Cypress operates in the network layer, it helps to modify the code that might interfere with the automation of the web browser. The communication between the Node server and Browser is via the WebSocket, which begins execution after the proxy is started.

Cypress controls all the commands that run in and out of the browsers. Since it is installed in a local machine, it directly interacts with the operating system to record videos, capture snapshots, accesses the network layer, and performs file system operations at ease. Cypress can access everything from DOM, window objects, local storage, network layer, and DevTools.

Install Cypress

This section will discuss the installation process that needs to be followed before writing our test cases. There are two different ways to download Cypress. They are

  1. Install via npm
  2. Direct Download

Before we install Cypress, we might need a few pre-requisites to kick start to install via npm. Let’s see them in detail.


We will require certain pre-requisites before writing our test cases.

  • As discussed above, Cypress runs on a node server; hence we will have to install Node.js.
  • Also, to write our test cases, we need a code editor or IDE.

In this example, we will be using Visual Studio Code. So let’s dive into the details.

New folder Creation

Now we have created a folder for our Cypress test. Before we begin writing our tests, we should install the package.json file. Before installing, let us understand what is package.json file.

What is Package.json file?

Package.json comprises all the npm packages in a file, usually located in the project root. It is commonly located in the root directory of the Node.js project. This file holds all the applicable metadata necessary for the project. It gives all the information to npm and helps in identifying the project and handle dependencies. Package.json file contains information such as project name, versions, license, dependencies, and many more.
Now we have understood what is package.json file. So, let’s begin the steps to download the file in our Visual Studio code.

Installation steps of Cypress

We have installed all the pre-requisites for our Cypress download, node, and initialized npm. As mentioned above, there are two ways to download Cypress.

Download Cypress via npm

You will have to pass the below-mentioned command in the Terminal to install Cypress. In addition, you will have to give the command in the project directory to install the node and generated the package.json file.

npm install cypress --save-dev

Successful Cypress Installation

With reference to the above image, you can see that we have downloaded Cypress. You can verify by the downloaded representation in Terminal and the addition of devDependencies in the package.json file.

Direct Download

We can download Cypress directly from their CDN if you are not using the Node or npm package in the project. However, recording the tests in the Dashboard is not possible via direct download.

You can download by clicking on download Cypress directly from this link. This will now directly download the package. Once the package is downloaded, open the zip file and double click. Cypress will run without the need for any installation of dependencies. This download will always pick up the latest version based, and the platform will be detected automatically. However, downloading Cypress via npm is recommended rather than a direct download.
