 * @method assert.elementsCount
 * @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#element-properties).
 * @param {string} count expected number of elements to be present.
 * @param {string} [msg] Optional log message to display in the output. If missing, one is displayed by default.
