How to get x and y coordinates of an element in protractor Node.js ?
Protractor is an end-to-end test framework that is developed for AngularJS and Angular applications. It basically runs the tests against the application which is interacting with it as a real user would, running in a real browser. In the following example, we are going to get the x and y coordinates of an element and check if it is as expected or not.
Pre-requisite: Installation and Setup of Protractor
Approach:
- We are going to create a basic test program in which we are going to check whether the x and y coordinates of an element is as expected or not.
- All the Protractor tests will have a file containing the configuration and this file will be the initial file that will initiate the test.
- Let’s create this file with the name conf.js.
Example: Filename: conf.js
Javascript
exports.config = { // Capabilities values for // webdriver instance capabilities: { 'browserName': 'chrome' }, // Framework value framework: 'jasmine', // The Spec patterns are relative to the // current working directory when // protractor is called. specs: ['test.js'], // Options which are passed to our // framework ie. Jasmine. jasmineNodeOpts: { defaultTimeoutInterval: 30000 }, // File URL onPrepare: function () { }}; |
Now let’s create our HTML file called test.html which will contain the element to be tested.
Filename: test.html
HTML
<!DOCTYPE html><html lang="en"><body> <!-- The element to be tested --> <div id="foo" style="position: absolute; top:20px; left: 15px"> Inner text </div></body></html> |
Now let’s create our test file test.js. In this file, we are going to access an HTML file and then get the x and y coordinates and will check if it is as set in the HTML file or not. Browser is a global created by Protractor.
Jasmine framework provides the describe() function and it() function where the describe is a description of your test while it is the steps for the test.
Filename: test.js
Javascript
describe('Protractor Demo App', function () { it('should have a title', function () { // Disabling waiting for angular browser.waitForAngularEnabled(false) // Get our html file for testing browser.get('test.html'); // Test if the element have required coordinates let foo = element(by.id('foo')); expect(foo.getLocation()).toEqual( jasmine.objectContaining({ x: 15, y: 20 })); });}); |
Run the conf.js file using the following command:
protractor conf.js
