API

global.browser

The Nightwatch browser API object. Unavailable when autoStartSession is off.

global.jestNightwatch

The Jest environment used the Nightwatch programmatic API to create the Nightwatch instance and export the browser API.

Available properties/methods:

• .element(<locator>) - use the Nightwatch .element() API to locate elements in the page;
• .updateCapabilities({ capabilities }) - used when autoStartSession is off in order to update the capabilities at run-time;
• .launchBrowser() - used when autoStartSession is off in order to start the session and open the browser;
• .settings - the Nightwatch settings object;
• .nightwatch_client - the Nightwatch (internal) instance.
