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.
