The Nightwatch team has completely redesigned the underlying architecture of Nightwatch for better cross-browser integration, more reliable DOM element handling and faster tests. It now uses the official Selenium Webdriver bindings for Node.js.
Here are the key features and improvements that make Nightwatch more powerful than ever before:
Support for Actions API
Automate complex gestures reliably with the new user actions API (via the existing
Expanded automatic command retries
Nightwatch will retry failed element commands (such as when click encounters errors like
element click intercepted).
New relative element locators
The new Selenium 4 relative locators are available by default in Nightwatch. It also improves upon the existing locators via the Selenium By() API.
Built-in support for working with file uploads
Uploading files with Nightwatch could be cumbersome previously, but v2 has a built-in command which works with the FileDetector API.
Support for extended Capabilities objects
The primary way of defining capabilities will still be as part of the
nightwatch.conf.js config file, but in v2, all capabilities objects created with the Selenium Capabilities API are also supported by default.
Setting network conditions in Chrome
Manipulating network conditions is a regularly needed feature when working with browser automation and v2 supports it for Chrome and Edge initially.
Support for working with Devtools Protocol
You can now execute Chrome DevTools commands with Nightwatch. The Chrome DevTools Protocol allows for tools to instrument, inspect, debug and profile Chromium-based browsers, such as Chrome and Edge.
Ready for Webdriver BiDi
Various new command APIs
Nightwatch v2 will also bring a new
.ensure assert API which will mirror the Selenium until APIs, global
browser objects which will enhance the experience of writing tests and provide more flexibility.
Test runner improvements
Nightwatch v2 will also bring some improvements to the test runner, like the ability to rerun only failed tests and improved support for parallel test execution.
This list is not exhaustive and Nightwatch v2 has a host of new updates. Visit nightwatch.org to learn more and upgrade to the latest version.
Nightwatch was published at the beginning of 2014 and was created as a complete and integrated framework that would enable engineers to write end-to-end tests quickly and require as little configuration and maintenance as possible.
Nightwatch recently joined the BrowserStack family, while continuing to develop Nightwatch as an autonomous open-source project. For developers who use Nightwatch.js for their testing needs, Nightwatch will always remain free and open-source. Together, BrowserStack and Nightwatch.js teams will make the framework better by improving the overall experience for developers and maintainers.
