Protractor is an end-to-end testing framework for AngularJS applications that combines tools like NodeJS, Selenium, Jasmine, and Mocha. It has customizations from Selenium to easily create tests for AngularJS apps and speeds up testing by reducing waits. Protractor allows organizing tests with Jasmine for both unit and functional testing and runs tests on real browsers. Setting up Protractor requires installing Node.js, Protractor, and Selenium Webdriver along with creating a spec file for tests and a conf file for configuration.

2.  Protractor is an end-to-end testing framework for AngularJS applications.
 combining powerful tools and technologies such as NodeJS, Selenium,
webDriver, Jasmine, Cucumber and Mocha.
 It has a bunch of customizations from Selenium to easily create tests for
AngularJS applications.
 Protractor also speeds up your testing as it avoids the need for a lot of
“sleeps” and “waits” in your tests, as it optimizes sleep and wait times.
 Protractor allows tests to be organized based on Jasmine, thus allowing you to
write both unit and functional tests on Jasmine.
 It runs on real browsers .

3. To set up protractor, we need to install below three things
1. Node.js
2. Protractor
3. Selenium Webdriver
Step 1: First we have to install NodeJS.
 Node.js is an event driven, lightweigth and efficient program.
 To install NodeJs we just need to download windows installer from Nodejs site
and follow installation wizard instruction and finish the installation.

4.  Check nodejs version by running command prompt.
C:> npm – version
Step 2: Installing protractor.
 Installing protractor can be done in two ways Locally and Globally.
 To install project directory, navigate to that folder and type the command
D: > ApplicationFolder > npm install protractor
 To install globally type the command
C: > npm install –g protractor

5. Step 3: Update selenium webdriver
 Run the update command, This will install the server and ChromeDriver.
C: >webdriver-manager update
 Run the start command, This will start the server. Keep running the server to
conduct the test session.
C: >webdriver-manager start

6.  To execute protractor , it need two files spec file (test file) and conf file
(configuration file).
 Conf File :
