Manually Download Browser Drivers

Nightwatch uses a WebDriver compatible server to control the browser. WebDriver is a W3C specification and industry standard which provides a platform and HTTP protocol to interact with a browser.

Nightwatch includes support for automatically managing the following services:

ChromeDriver

GeckoDriver

Selenium Standalone Server

It's important to note that, while the Selenium Server was required with older Nightwatch versions (v0.9 and prior), starting with version 1.0 the Selenium Server is no longer necessary.

Specific WebDriver setup guides can be found on the Docs website. Legacy Selenium drivers setup guides along with debugging instructions can be found on the Wiki.

Nightwatch unit tests

The tests for Nightwatch are written using Mocha.

1. Clone the project

$ git clone https://github.com/nightwatchjs/nightwatch.git
$ cd nightwatch
$ 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.
