Protractor: How to access the `ElementFinder` class from within a test

Question

i'm looking for a way to extend protractor's ElementFinder class from within a test. Is there a way to access protractor's ElementFinder class/constructor so i would be able to extend it dynamically from within a test?

A reference of all global variables exposed by protractor would also be very helpfull.

Answer 1

I'm using below workaround $('').constructor; to extend ElementFinder features until #1102.

/**
 * Current workaround until https://github.com/angular/protractor/issues/1102
 * @type {Function}
 */
var ElementFinder = $('').constructor;

// Examples:

/**
 * Schedules a command to compute the width of this element's
 * bounding box, in pixels.
 * @return {!webdriver.promise.Promise.<number>} A promise that will
 *     be resolved with the element's width as a {@code {number}}.
 */
ElementFinder.prototype.getWidth = function() {
    return this.getSize().then(function(size) {
        return size.width;
    });
};

/**
 * Schedules a command to compute the height of this element's
 * bounding box, in pixels.
 * @return {!webdriver.promise.Promise.<number>} A promise that will
 *     be resolved with the element's height as a {@code {number}}.
 */
ElementFinder.prototype.getHeight = function() {
    return this.getSize().then(function(size) {
        return size.height;
    });
};
