TestCafe is a powerful, free and open-source Node.js tool for automating end-to-end web testing on desktop browsers, mobile devices, remote servers, and cloud browsers.
Note: You can also run your TestCafe test scripts on LambdaTest cloud.
TestCafe Studio was engineered from scratch for modern web and browser applications and did not rely upon Selenium or other legacy testing platforms. TestCafe Studio was created with developers and QA engineers in mind so that they can simplify the testing process. In addition, with LambdaTest’s scalable, cloud-based infrastructure, you can efficiently parallelize your TestCafe test scripts to improve your execution speed dramatically.
TestCafe is a popular test automation framework, according to the data on its official GitHub repository:
As of this writing, TestCafe had 254,003 weekly downloads on NPM.
As per The State of JS 2021 Survey, TestCafe has the highest counts in the “Other tools” category. This indicates a positive rise in its usage and popularity.
TestCafe has several features that make it easier to use than competing solutions.
Here are some of the key features of the TestCafe framework:
Here are some Playwright testing drawbacks:
TestCafe's hybrid client-server architecture means it can execute both system-level and browser code in real-time.
TestCafe’s architecture combines the browser and Node.js. An early version of TestCafe ran entirely in the browser, but a hybrid architecture allowed us to improve test stability and extend the framework’s testing capabilities.
TestCafe was released in 2016 and quickly became known as a competitor to Selenium, the most popular framework for web application testing at the time. It was difficult to set up a robust testing framework using Selenium; one had to install JDK, TestNG/JUnit, and many other jars as per the requirement of the framework. The test automation framework setup took a lot of time and effort and was difficult work, especially for novice automation QAs. Moreover, even after setting up the framework, results were not satisfactory due to test flakiness and slowness.
In October 2016, the DevExpress team announced a NodeJS-based automation framework that worked out of the box. Since then, they have maintained its zero-configuration policy at TestCafe.
On the other hand, TestCafe uses a test runner that initially seems a bit strange, but a lot of testers prefer it makes you explicitly use promises and async/await to manage execution.
TestCafe works by serving the test site through a proxy server that injects scripts into the page. These scripts can inspect and control elements on the page, as well as interact with native alerts, file upload inputs and iframes. This allows it to work in any web browser, including mobile devices and cloud services like LambdaTest.
Cypress is a test runner that controls the browser via its proprietary automation APIs. Because Cypress uses these APIs instead of Selenium WebDriver, it needs a new driver for every supported browser. As of early 2018, it supports Chrome and family (Chromium, Electron) and Firefox, with plans to add Edge and Safari support later on. It also has plans to support older browsers via Selenium WebDriver.
Cypress runs your tests in the browser, whereas TestCafe runs them in Node. This means that Cypress tests can access real DOM elements but in TestCafe you must serialise the communication between your tests and the DOM.
TestCafe can call out parts of your Node server application directly from tests. This allows you to easily set up and clear database fixtures or start and stop your test server. Unfortunately, Cypress doesn’t let you communicate with your app via HTTP or execute shell commands.
Both TestCafe and Cypress are great tools for testing web applications. We look forward to seeing how they continue to improve in the future.
TestCafe is compatible with all major browsers, including:
LambdaTest is a leading test execution and orchestration platform that is fast, reliable, scalable, and secure. It allows users to run both manual and automated testing of web and mobile apps across 3000+ different browsers, operating systems, and real device combinations. Using LambdaTest, businesses can ensure quicker developer feedback and hence achieve faster go to market. Over 500 enterprises and 1 Million + users across 130+ countries rely on LambdaTest for their testing needs.
TestCafe cloud grids like LambdaTest allow you to perform TestCafe testing at scale. LambdaTest allows you to perform automated cross browser testing on an online browser farm of 40+ browsers and operating systems to expedite the test execution in a scalable way. Moreover, it increases the test coverage with better product quality.
