AngularJS End to End (E2E) Testing | Protractor

Protractor is an end-to-end test framework developed for Angular and AngularJS applications. It run tests against the application interacting with it as a real user would, running in a real browser. In this article, we are going to create a basic test.

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 title of the Angular web app is correct or not. 
• All the Protractor tests will have a file which 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:

exports.config = {

    // Capabilities to be passed to the 
    // webdriver instance.
    // Here we are specifying the browser
    // to be chrome
    capabilities: {
        'browserName': 'chrome'
    },

    // Framework to use. Jasmine is
    // being used here.
    framework: 'jasmine',

    // The test file which are relative
    // to the current working directory
    // when protractor is called.
    specs: ['test.js'],

    // Options to be passed to Jasmine.
    jasmineNodeOpts: {
        defaultTimeoutInterval: 30000
    }
};

• Now let's create our test file test.js. In this file, we are going to access an AngularJS web app and then check if the title is correct or not. 
• 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:

describe('Protractor Demo App', function () {
    it('should have a title', function () {

        // Open the AngularJS webpage
        browser.get(
    'http://juliemr.github.io/protractor-demo/');

        // Check if the title is 'Super
        //  Calculator' or not.
        expect(browser.getTitle())
            .toEqual('Super Calculator');
    });
});

• 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:
