Mobile Web Automation using Protractor

14 / Sep / 2016 by Kimi Agarwal 0 comments

Protractor is an end-to-end automation testing framework tool. To test Angular web page on a mobile device, we have to use the Appium with Protractor to perform our E2E testing. Both Appium and Protractor are open-source automation testing tool. Appium provides a bridge between a system and a mobile device. It supports three types of mobile application:

  • Native
  • Mobile Web
  • Hybrid application

Step-by-Step Installation

Step 1:- Download & install the Chrome browser in the system where we run our test.

Step 2:- Download the ‘Recommended For Most Users’ one Node.js and then install it.

Step 3:- Now we need to check whether Node.js is installed correctly or not on our machine

Open console window and type npm –version [This will display the npm version]

Step 4:- To install Protractor, type npm install –g protractor [This command globally installs the Protractor using node package manager]

Type protractor –version [This will display the Protractor version]

Type npm -g list [This will give all the nodes which you have installed]

Step 5:- Install and set up Java

Type java -version [You will get the java version]

Step 6:- Setting up a Selenium Server

Type webdriver-manager update [This is for updating the Chrome driver]

Type webdriver-manager start [This command will start up a Selenium Server and will output a cluster of data logs]

Step 7:- To install Appium through NPM type npm install -g appium

Step 8:- Download Appium on your system

Install it by clicking on appium-installer.exe than launch Appium.

Step 9:- Attach mobile device with your system and check that whether the device is attached or not with the help of command adb devices on the command prompt window.

Setup conf.js File

Normally, Protractor runs test on localhost:4444. However, we need Protractor to connect with Appium which runs test on localhost:4723

Some capabilities must be set in the conf.js to make sure Appium can connect to your device which are given below:

  • appium-version: Version of Appium tool.
  • platformName: Name of the device OS platform wants to utilize
  • platformVersion: Name of the device OS version wants to use
  • deviceName: Actual device number or name which is connected to our system.

A Use Case

  1. Go to ‘Contact Us’ page
  2. Enter all the valid credentials in the Request for services form leaving behind the ‘Requirement’ field
  3. Click on the ‘Talk to Us’ Button
  4. Verify the error message.


Our First Test Script

Following is the code piece for our use case.

As my application is non-angularJS for that I’m using the following command in my script browser.ignoreSynchronization = true;

In this test script, in order to click the button we are using the script: element(by.css(‘[id=”edit-submit”]’));

In our mobile device web application, the HTML Code for the button is: <input data-drupal-selector=”edit-submit” type=”submit” id=”edit-submit” name=”op” value=”Talk to Us” class=”button js-form-submit form-submit”>

Types of Locators

A locator directly helps Protractor to identify elements. Following is the list of locators we can use:

  1. Find an element utilizing a CSS selector css(‘.myclass’)
  2. Find an element with a specified id id(‘myid’)
  3. Find an element with a specific ng-model model(‘name’)
  4. Find an element bound to a given variable binding(‘bindingname’)

Run the Test Script

  • Once all the above steps are completed. Open a new console window and give the path of the test script ‘AppData\Roaming\npm\node_modules\protractor\example’.
  • Run the script with protractor conf.js

As the script runs, the Chrome browser window will maximize on the mobile device and will be navigated to the TO THE NEW contact us page, automatically details in the ‘Request for Service’ form will be filled and ‘Talk to Us’ button will be clicked and with that the browser closes itself.

The protractor automation tool is specially designed for AngularJS application, but we can also use this tool to test the non-AngularJS application.
