In fact, software testing is progressively integrating automated testing tools across their companies, as free or open source tools offer extensive serviceability in contrast to commercial testing tools. Open-source testing tools like Cypress are up-and-coming automated web testing frameworks. With Cypress, one can easily generate tests for modern web apps, visually debug them, and automatically execute them in the CI (continuous integration) builds. This ever-growing solution for web automated testing is a solid complementary framework to the popular tool like Selenium, which has long been the de facto automated web framework.
What is Cypress?
It is a NodeJS based, front-end automated testing application shaped for the modern web. This incredible tool is built on the newest architecture and runs in a similar run-loop as the app being tested. As a result, Cypress offers faster, better, as well as highly reliable testing for anything that runs in any browser. Cypress functions on any front-end website or framework.
Cypress E2E testing is one of the key uses of the framework. It is also suited for writing integration and unit tests. In short, architectural differences and suitability to test advanced and modern web apps are the core rewards of the Cypress framework. Just like the Selenium framework, Cypress cloud testing allows you to run Cypress testing at scale on a series of diverse browsers, browser versions, and OSs online.
Cypress testing framework is highly speedy, reliable, and less flaky in contrast to tests executed using varied web automation testing frameworks. However, as it is rightly said, ‘No. don’t lie,’ & 3.5M+ weekly downloads for Cypress tests framework tells a lot about the fame of this free/ open-source automated test framework.
Who uses Cypress?
Salient Features of Cypress
Cypress is a modern E2E testing framework that provides various salient features, counting:
- Automatic waiting: This tool automatically waits for your app to end rendering before implementing the next command. This eradicates the requirement for manual waits & timeouts, keeping your tests speedier and more reliable. You can also refer to Explicit Waits in Selenium blog to get extra information about the kinds of waits in Selenium. Due to this, Cypress testing is less flaky than their equal Selenium testing.
- Real-time reloading: Cypress reloads your application automatically in the browser when you make alterations to your test or app code. This lets you rapidly iterate on your testing and fix glitches as they arise.
- Full page screenshots: Full page screenshots are automatically generated for all event that is fired at the time of test implementation. In simple words, video recording of the test implementation is also possible in a tool like Cypress.
- Time-travel debugging: This tool also allows you to pause your testing at any point plus debug it using Chrome DevTools. You could also step through every single command in your testing and see the state of your app at any point in time.
- Timeouts and Retries: Cypress retries failed testing automatically and give configurable timeouts for extended-running jobs, guaranteeing that your test is resilient to network and server problems.
- Cross-browser testing: It also supports cross-browser testing by executing tests in numerous browsers at the same time. This helps guarantee that your app functions as predictable on diverse platforms and browsers.
- Open-source and community-driven: This tool is open-source/ free software and has a huge community that contributes to its support and development. This guarantees that the framework is continuously evolving and refining over time.
- Spies, stubs, and mocks: It also provides powerful utilities for stubbing, spying, and mocking functions, requests, and objects. This lets you simulate diverse scenarios & test your app’s behavior under several conditions.
Overall, Cypress provides a modern and robust automated testing framework that can aid you to build and manage top-quality web apps.
Everyone knows that web scraping in Se is simply doable. Additionally, you have the flexibility to use standard Selenium-supported languages such as Java, Python, C#, etc., to accomplish the task. In the weak zone, Cypress isn’t a preferred option for web crawling (or web scraping) and performance testing.
Why is Cypress better than other tools?
Cypress has several benefits that make it a famous choice for test automated, comprising:
- Easy to use: Cypress has an easy as well as intuitive API that makes it simple for software developers for writing and maintaining tests.

Advantages and disadvantages of using Cypress for automated testing
While Cypress proffers numerous advantages over other test frameworks, it also has some disadvantages. Here are some of the advantages & disadvantages of using Cypress for automated testing:
- Simple to use: Cypress has a simple and intuitive App Programming Interface that makes it simple for software developers to write tests. The test framework comes with a customer-friendly interface that enables developers to relate to their web apps and test them without the necessity for extra tools.
- Reliable and Speedy testing: It is built on top of Electron, which makes it highly reliable and faster than distinct testing frameworks. The test framework is well-designed to perform testing in real-time, which means that software developers can get immediate feedback on their testing.
- Robust testing competencies: Cypress gives software developers a choice of testing abilities, and counting support for E2E testing, unit testing, and integration testing. The tool also has built-in support for popular test libraries like Chai and Mocha.
- Debugging and error handling: Cypress has a range of built-in debugging tools that allow developers to quickly and easily identify and fix errors in their tests. The framework also provides detailed error messages and stack traces that make it easier for developers to diagnose issues.
- Cross-browser & cross-platform testing: It supports cross-browser plus cross-platform testing, which means that software developers can test their web apps on multiple browsers and OSs. This feature guarantees that the app functions constantly across all varied devices and platforms.
- CI (Continuous integration) and deployment: Cypress incorporates well with popular ci and deployment tools like CircleCI and Jenkins. This integration lets software developers automate their testing processes and guarantee that their app is perfectly tested and deployed in a consistent plus reliable manner.
Overall, Cypress is a powerful and easy-to-use testing framework that provides developers with a range of advanced testing capabilities. Its robust testing capabilities, fast and reliable testing, and cross-platform support make it an ideal choice for modern web development projects.
While Cypress offers multiple benefits for test automation, there are also some potential disadvantages to consider:
- Restricted mobile testing support: While Cypress can test mobile sites or apps using Chrome DevTools, it does not support native mobile application testing, which may be a drawback for some apps.
- Limited browser support: Cypress is mainly designed to function only in Electron and Chrome browsers, so it might not be suitable for apps that necessitate tests on other browsers such as Firefox or Safari.
- Limited community support: While Cypress has a rising community, it is still comparatively new compared to other test frameworks, so there may be lesser support and resources accessible in contrast to more established frameworks.
- Cost: While Cypress is simple to use, a few traits like dashboard & parallel test necessitate a paid plan, which might not be suitable for some QA teams with budget restrictions.
The Cypress test runner and Cypress dashboard are the two major elements that will be installed with Cypress. Perform the below-mentioned stages for installing Cypress on the local machine:
- As Cypress is built using NodeJS, you prime need to install NodeJS v12+ before continuing to install Cypress.
- Once NodeJS is installed, you need to form a project folder under the suitable directory & initialize the folder with the npm init command.
- Cypress is a sole module that bundles all the essential properties that you require to run the testing. Adding Cypress to node_modules Installing Cypress is simply a command away as it’s a sole module bundling all mandatory properties.
Cypress can be added to node_modules with yarn or npm by making use of either of the following commands:
|yard add cypress
npm install cypress
- Once Cypress packages are included in the project directory, you need to observe the Cypress folder added to your project with pre-defined tests for sample tests.
