Protractor for AngularJS in Automation Testing

Protractor is an end-to-end testing framework, is an open source automation for Angular and AngularJS applications. It is designed by Google developers on the top of webdriverJS for node.js program. It tests your application running in a real world browser that interacts with its users. It extends webdriverJS functionalities on web applications to enable automation of useractions.

"End-to-End Testing" is a methodology which is used to test the flow of application from start to end or verify the use-cases and user scenario of the application.

"AngularJS" is an open-source framework to build for front-end applications for the web. It is a javascript based framework maintained by Google. It is referred to as Angular.

Protractor vs. Selenium: Which is easier for testing?

• Selenium’s performance is faster in normal/web applications and Protractor’s performance is faster in angular application.
• Selenium can be used to automate any technology based application that needs a browser whereas protractor is specially used for automating angular application.
• In selenium we use implicit wait to load the webpage whereas we don’t need to use implicit wait to load the webpage in protractor.
• Selenium supports locator strategies for all types of web/browser applications whereas Protractor supports all types of locator strategies supported by selenium extra angular specific locator strategies.

To create first test case in Protractor:

For the basic program use visual studio code IDE. To run the code below, you will need to have Node.js and selenium installed and download the protractor package using npm.

• Use npm to install Protractor globally:

Open cmd and type below codes

npm install -g protractor

• The webdriver-manager is a helper tool to easily get an instance of a Selenium Server running (optional step).

webdriver-manager update // After protractor is installed, webdriver manager needs to be updated to latest version.

webdriver-manager start //webdriver need to run in background

• Use Jasmine framework in Protractor

1. Jasmine is basically a javascript framework which supports a behaviour-driven JS approach.
2. We create a test(specs) file to run protractor and write our actual test code. This file contains logic and locator to interact with application.
3. describe and it-> Both are used in jasmine framework. "describe" is used for the end to end flow of our test case or test suites and "it" is used to contain the test scenario. One "describe" can also contain multiple "it" blocks.
4. expect-> it works as an assertion for comparing the expected and actual value just like assert works in selenium.
