Easy to use Node.js based end-to-end testing solution for web applications using the W3C WebDriver API.

/**
 * Checks if the given element is enabled (as indicated by the 'disabled' attribute).
 *
 * @example
 * this.demoTest = function (browser) {
 *   browser.assert.enabled('.should_be_enabled');
 *   browser.assert.enabled({selector: '.should_be_enabled'});
 *   browser.assert.enabled({selector: '.should_be_enabled', suppressNotFoundErrors: true});
 * };
 *
 * @method assert.enabled
 * @param {string|object} definition The selector (CSS / Xpath) used to locate the element. Can either be a string or an object which specifies [element properties](https://nightwatchjs.org/guide/working-with-page-objects/#element-properties).
 * @param {string} [msg] Optional log message to display in the output. If missing, one is displayed by default.
 * @api assertions
