Similar Npm Packages to nightwatch

nightwatch is an end-to-end testing framework for web applications and websites, built on Node.js. It allows developers to write tests in JavaScript using a simple and expressive syntax. Nightwatch is particularly known for its ease of use and ability to run tests in various browsers, making it a popular choice for automated testing in web development. While Nightwatch provides a robust solution for testing, there are several alternatives in the testing ecosystem that offer similar functionalities. Here are a few notable options:

  • cypress is a modern end-to-end testing framework that is designed specifically for web applications. It provides a rich set of features, including real-time reloading, automatic waiting, and an interactive test runner, making it easy to write and debug tests. Cypress is particularly well-suited for developers looking for a fast and reliable testing tool that integrates seamlessly with modern JavaScript frameworks. Its user-friendly interface and comprehensive documentation make it a popular choice among developers for testing web applications.
  • protractor is an end-to-end testing framework specifically designed for Angular and AngularJS applications. Built on top of WebDriverJS, Protractor provides a robust solution for testing Angular applications by understanding their unique features, such as two-way data binding and asynchronous operations. While Protractor was widely used in the Angular community, it has seen a decline in popularity with the rise of other frameworks like Cypress. However, it remains a solid choice for developers working primarily with Angular applications.
  • testcafe is another end-to-end testing framework that allows developers to write tests in JavaScript or TypeScript. It offers a simple API, built-in support for parallel test execution, and the ability to run tests on multiple browsers without the need for browser plugins. TestCafe is known for its ease of setup and ability to test web applications across different platforms, making it a versatile choice for developers looking for a straightforward testing solution.
  • webdriverio is a popular testing framework that provides a powerful and flexible API for writing automated tests using WebDriver. It supports both Selenium and Appium, allowing developers to test web and mobile applications. WebdriverIO is highly customizable and can be integrated with various testing libraries and frameworks, making it a great choice for developers who need a more tailored testing solution.

🚀 Nightwatch v3

What's New | Release Notes | Discussions

Nightwatch v3 is an all new generation that has been built around these three pillars:

  • Developer Experience : The entire experience from getting started, to writing and debugging tests, has been redesigned for speed, stability, and consistent non-flaky results.

  • Mobile first: Test your web or native, iOS and Android, mobile applications on simulators, real mobile devices or a cloud grid like BrowserStack.

  • One test automation framework: Run all types of tests from unit, component, and E2E to API, visual, and accessibility with a single framework.

The Nightwatch v3 is not just a new version, it’s the result of months of engineering effort to reimagine test automation for the future. Try it out in 60 seconds and see it in action.

⚙️ Get started in 60 seconds

1. Install Nightwatch from NPM

From your existing project's root dir:

npm init nightwatch@latest

or, if you want to initialize a new project:

npm init nightwatch@latest ./path/to/new/project

nightwatch-cli-gif

2. Answer a few questions about your preferred setup:

  • What is your Language - Test Runner setup?
  • Where do you want to run your e2e tests?
  • Where you'll be testing on?
  • Where do you plan to keep your end-to-end tests?
  • What is the base_url of your project?

Nightwatch will do the entire setup for you based on your answers.

3. Run a Demo Test:

Nightwatch comes with a few examples, which are automatically copied to your Nightwatch project during the setup and can also be used as boilerplate to write your own tests on top of them.

You can follow the instructions given at the end of the setup to run your first test with Nightwatch.

Go beyond E2E

Component testing

With Nightwatch you can test components in isolation by mounting them in the browser. Nightwatch 2 added support for component testing for popular web frameworks such as

  1. React
  2. VueJS
  3. Angular
  4. Storybook

Nightwatch unit tests

The tests for Nightwatch are written using Mocha.

# change directory
cd nightwatch

# install the dependencies
npm install

  2. Run tests

    To run the complete test suite:

    npm test

    To check test coverage, run the command:

    npm run mocha-coverage

    and then open the generated coverage/index.html file in your browser.

See Unit testing guide for more details.

Other types of testing

Visual Regression Testing

Nightwatch v3 introduces visual regression testing as an in-house plugin. The plugin takes care of

  1. Capturing screenshots
  2. Comparison with baseline to highlight visual differences
  3. Report to review the differences
  4. Approve the changes

VRT can be done on real desktop & mobile browsers. Also, VRT can be run on components as part of component testing as well.

API Testing

API testing is now available with Nightwatch v3. The following functionality can be achieved with API testing

  1. Request assertions
  2. Response assertions
  3. Viewing API tests in the HTML report
  4. Mock server

Accessibility Testing

Nightwatch v3 packages the aXe-core package developed by Deque Systems as a plugin. It enables 90 different types of accessibility tests for WCAG compliance.
