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.)

Getting Started

Installation

Ensure that Node.js (version 4 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.

You can use these plugin generators to create your own plugins:

• 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.
