testcafe

What is testcafe?

TestCafe is an end-to-end testing framework for web applications. It allows you to write tests in JavaScript or TypeScript, run them across multiple browsers, and provides a rich set of features for automating user interactions and verifying application behavior.

What are testcafe's main functionalities?

Cross-browser Testing

TestCafe allows you to run tests across multiple browsers simultaneously. This code sample demonstrates how to set up TestCafe to run tests in both Chrome and Firefox.

const createTestCafe = require('testcafe');
let testcafe = null;

createTestCafe('localhost', 1337, 1338)
    .then(tc => {
        testcafe = tc;
        const runner = testcafe.createRunner();

        return runner
            .src('tests/test.js')
            .browsers(['chrome', 'firefox'])
            .run();
    })
    .then(failedCount => {
        console.log('Tests failed: ' + failedCount);
        testcafe.close();
    });

Assertions

TestCafe provides a rich set of assertions to verify the state of your application. This code sample demonstrates how to use assertions to check that the text of an element matches the expected value.

import { Selector } from 'testcafe';

fixture `Getting Started`
    .page `http://devexpress.github.io/testcafe/example`;

const developerNameInput = Selector('#developer-name');
const submitButton = Selector('#submit-button');
const articleHeader = Selector('#article-header');






test('My first test', async t => {
    await t
        .typeText(developerNameInput, 'John Smith')
        .click(submitButton)
        .expect(articleHeader.innerText).eql('Thank you, John Smith!');
});

Screenshots and Video Recording

TestCafe allows you to take screenshots and record videos of your tests. This code sample demonstrates how to take a screenshot after performing some actions.

import { Selector } from 'testcafe';

fixture `Screenshot and Video`
    .page `http://devexpress.github.io/testcafe/example`;

const developerNameInput = Selector('#developer-name');
const submitButton = Selector('#submit-button');






test('Take a screenshot', async t => {
    await t
        .typeText(developerNameInput, 'John Smith')
        .click(submitButton)
        .takeScreenshot();
});

Parallel Test Execution

TestCafe supports parallel test execution to speed up the testing process. This code sample demonstrates how to run tests in parallel with a concurrency factor of 3.

const createTestCafe = require('testcafe');
let testcafe = null;

createTestCafe('localhost', 1337, 1338)
    .then(tc => {
        testcafe = tc;
        const runner = testcafe.createRunner();

        return runner
            .src('tests/test.js')
            .browsers(['chrome', 'firefox'])
            .concurrency(3)
            .run();
    })
    .then(failedCount => {
        console.log('Tests failed: ' + failedCount);
        testcafe.close();
    });

Other packages similar to testcafe

cypress

Cypress is a front-end testing tool built for the modern web. It offers a rich, interactive UI and a powerful API for writing tests. Compared to TestCafe, Cypress provides a more interactive debugging experience but is limited to running tests in Chrome and Electron.

selenium-webdriver

Selenium WebDriver is a widely-used tool for automating web browsers. It supports multiple programming languages and browsers. Compared to TestCafe, Selenium WebDriver offers more flexibility and control but requires more setup and configuration.

puppeteer

Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It is great for automating browser tasks and scraping. Compared to TestCafe, Puppeteer is more low-level and requires more boilerplate code for writing tests.
