Protractor is an end-to-end test framework developed for Angular and AngularJS applications. It runs tests against the application interacting with it as a real user would, running in a real browser. In this article, we are going to test the id of an element.
Pre-requisite: Installation and Setup of Protractor
Approach:
- We are going to create a basic test program in which we are going to test the id of an element.
- All the Protractor tests will have a file that will contain the configuration and this will be the initial file that will initiate the test.
- Let’s create this file with the name conf.js.
conf.js:
Javascript
exports.config = {// Capabilities to be passed to the// webdriver instancecapabilities: {'browserName':'chrome'},// Framework to use. Jasmine is recommendedframework:'jasmine',// Spec patterns are relative// to the current working directory when// protractor is called.specs: ['test.js'],// Options to be passed to JasminejasmineNodeOpts: {defaultTimeoutInterval: 30000},// Url for the fileonPrepare:function() {}};- Now let’s create our HTML file called test.html which will contain the element to be tested.
HTML
<!DOCTYPE html><htmllang="en"><head><metacharset="UTF-8"><metaname="viewport"content="width=device-width, initial-scale=1.0"><title>Testing</title></head><body><!-- The element to be tested --><sectionclass="sample-element"id="neveropen">Inner text</section></body></html>
- Now let’s create our test file test.js. In this file, we are going to access an HTML file and test the id of an element.
- Browser is a global created by Protractor, which is used for browser-level commands such as navigation with browser.get.
- The describe and it syntax is from the Jasmine framework where describe is a description of your test while it is the steps for the test.
The spec file named test.js:
Javascript
describe('Protractor Demo App',function() {it('should have a id',function() {// Disabling waiting for angularbrowser.waitForAngularEnabled(false)// Get our html file for testingbrowser.get('test.html');// Test if the element with class// 'sample-element' has the id// 'neveropen'let sampleDiv = element(by.className('sample-element'));expect(sampleDiv.getAttribute('id')).toEqual('neveropen');});});- Finally, we are ready to run our file using the command given below:
protractor conf.js
- This will run the configuration file and the test will be run as shown in the screenshot below:
