Protractor End to End Automation for Angular

Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would. Protractor is built on top of WebDriverJS, which uses native events and browser-specific drivers to interact with your application as a user would. Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part. You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync.

Prerequisites
  • Protractor is a Node.js program. To run, you will need to have Node.js installed. You will download Protractor package using npm, which comes with Node.js. Check the version of Node.js you have by running node --version. Then, check the compatibility notes in the Protractor README to make sure your version of Node.js is compatible with Protractor. By default, Protractor uses the Jasmine test framework for its testing interface. This tutorial assumes some familiarity with Jasmine, and we will use version 2.4. This tutorial will set up a test using a local standalone Selenium Server to control browsers. You will need to have the Java Development Kit (JDK) installed to run the standalone Selenium Server. Check this by running java -version from the command line.
Setup
  • Use npm to install Protractor globally with: npm install -g protractor
  • This will install two command line tools, protractor and webdriver-manager. Try running protractor --version to make sure it's working. The webdriver-manager is a helper tool to easily get an instance of a Selenium Server running.
  • Use it to download the necessary binaries with: webdriver-manager update
  • Now start up a server with: webdriver-manager start
  • This will start up a Selenium Server and will output a bunch of info logs. Your Protractor test will send requests to this server to control a local browser. Leave this server running throughout the tutorial. You can see information about the status of the server at http://localhost:4444/wd/hub.
