Retrieve the value of an attribute for a given DOM element.

The command getAttribute() will automatically wait for the element to be present (until the specified timeout). If the element is not found, an error is thrown which will cause the test to fail. You can suppress element not found errors by specifying the selector argument as an object and passing the suppressNotFoundErrors = true option.

For more info on working with DOM elements in Nightwatch, refer to the Finding & interacting with DOM Elements guide page.

    browser.getAttribute('#main ul li a.first', 'href', function(result) {

    });

    // with explicit locate strategy
    browser.getAttribute('css selector', '#main ul li a.first', 'href', function(result) {
