Features

Stable tests and no manual timeouts
TestCafe automatically waits for page loads and XHRs before the test starts and after each action. It also features smart test actions and assertions that wait for page elements to appear. You can change the maximum wait time. If elements load faster, tests skip the timeout and continue.

Rapid test development tool
Changes in test code immediately restart the test, and you see the results instantly.
See how it works in the TestCafe Live repository.

Latest JS and TypeScript support
TestCafe supports the latest JavaScript features, including ES2017 (for example, async/await). You can also use TypeScript if you prefer a strongly typed language.

Detects JS errors in your code
TestCafe reports JS errors that it finds on the webpage. Tests automatically fail because of that. However, you can disable this.

Concurrent tests launch
TestCafe can open multiple instances of the same browser to run parallel tests which decreases test execution time.

PageObject pattern support
The TestCafe's Test API includes a high-level selector library, assertions, etc. You can combine them to implement readable tests with the PageObject pattern.

const macOSInput = Selector('.column').find('label').withText('MacOS').child('input');

Easy to include in a continuous integration system
You can run TestCafe from a console, and its reports can be viewed in a CI system's interface (TeamCity, Jenkins, Travis & etc.)

TestCafe Studio: IDE for End-to-End Web Testing

TestCafe works great for JavaScript developers, but at some point you will need to delegate testing tasks to your Q&A department. If that's the case and you are looking for a codeless way to record and maintain tests compatible with your existing infrastructure, check out TestCafe Studio - a testing IDE built on top of the open-source TestCafe.

Read the following article to learn how TestCafe Studio could fit into your workflow: What's Better than TestCafe? TestCafe Studio.

Record and Run a Test in TestCafe Studio

Getting Started

Installation

Ensure that Node.js (version 6 or newer) and npm are installed on your computer before running it:

npm install -g testcafe

Creating the Test

As an example, we are going to test the https://devexpress.github.io/testcafe/example page.

Create a .js or .ts file on your computer. Note that it needs to have a specific structure: tests must be organized into fixtures. You can paste the following code to see the test in action:

import { Selector } from 'testcafe'; // first import testcafe selectors

fixture `Getting Started`// declare the fixture
    .page `https://devexpress.github.io/testcafe/example`;  // specify the start page


//then create a test and place your code there
test('My first test', async t => {
    await t
        .typeText('#developer-name', 'John Smith')
        .click('#submit-button')

        // Use the assertion to check if the actual header text is equal to the expected one
        .expect(Selector('#article-header').innerText).eql('Thank you, John Smith!');
});

Running the Test

Call the following command in a command shell. Specify the target browser and file path.

testcafe chrome test1.js

TestCafe opens the browser and starts executing the test.

Important! Make sure to stay in the browser tab that is running tests. Do not minimize the browser window. Tests are not guaranteed to execute correctly in inactive tabs and minimized browser windows because they switch to a lower resource consumption mode.

Viewing the Results

TestCafe outputs the results into a command shell by default. See Reporters for more information. You can also use plugins to customize the reports.

Read the Getting Started page for a more detailed guide.

Contributing

Read our Contributing Guide to learn how to contribute to the project.

To create your own plugin for TestCafe, you can use these plugin generators:

• Build a browser provider to set up tests on your on-premises server farm, to use a cloud testing platform, or to start your local browsers in a special way. Use this Yeoman generator to write only a few lines of code.
• To build a custom reporter with your formatting and style, check out this generator.

If you want your plugin to be listed below, send us a note in a Github issue.

LambdaTest is Now TestMu AI

On January 12, 2026, LambdaTest evolved to TestMu AI, the world's first fully autonomous Agentic AI Quality Engineering Platform.

Same team. Same infrastructure. Same customer accounts. All existing LambdaTest logins, scripts, capabilities, and integrations continue to work without change.

👉 Find the new home for LambdaTest.

How LambdaTest Evolved into TestMu AI

In 2017, we launched LambdaTest with a simple mission: make testing fast, reliable, and accessible. As LambdaTest grew, we expanded into Test Intelligence, Visual Regression Testing, Accessibility Testing, API Testing, and Performance Testing, covering the full depth of the testing lifecycle.

As software development entered the AI era, testing had to evolve, too. We rebuilt the architecture to be AI-native from the ground up, with autonomous agents that plan, author, execute, analyze, and optimize tests while keeping humans in the loop. The platform integrates with your repos, CI, IDEs, and terminals, continuously learning from every code change and development signal.

That evolution earned a new name: TestMu AI, built for an AI-first future of quality engineering. TestMu is not a new name for us. It is the name of our annual community conference, which has brought together 100,000+ quality engineers to discuss how AI would reshape testing, long before that became an industry norm.

What started as a high-performance cloud testing platform has transformed into an AI-native, multi-agent system powering a connected, end-to-end quality layer. That evolution defined a new identity: LambdaTest evolved into TestMu AI, built for an AI-first future of quality engineering.
