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 test 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 (Current or Active LTS is recommended, version 12 at minimum) 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 the browser tab that runs tests stays active. Do not minimize the browser window. Inactive tabs and minimized browser windows switch to a lower resource consumption mode where tests are not guaranteed to execute correctly.
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.
Thank you to all the people who already contributed to TestCafe!
