What is Protractor ?
 An AngularJS E2E Testing Framework
 Find Issues -Integration between components
 Introduced during AngularJS 1.2 and Beyond presentation
 A new replacement of the existing E2E Testing framework
 Nodejs program – end to end test run written in javascript
 Webdriver – control browsers and simulate user actions
 Jasmin – test syntax
 Allows running tests targeting remote addresses, No longer
need to have test files on the server being tested

What’s Different ?
 Built on WebdriverJS and Selenium Server
 New syntax when writing tests
 Allows running tests targeting remote addresses, No longer
need to have test files on the server being tested
 Can take advantage of Selenium Grid to run multiple
browsers at once; ie Sauce Labs
 Has it’s own runner, no need for Karma
 Can use Jasmine or Mocha to write test suites

List of Contents:
● HOW IT WORKS
● FRAMEWORK OR DRIVERS USED
● HOW TO INSTALL AND RUN
● WRITE A TEST

HOW IT WORKS
1) Selenium server
Browser automation framework
 Selenium server
 Webdriver APIs
 Browser driver
2) Protractor
Node js program that support jasmine framework

HOW IT WORKS
• Conjunction of protractor with selenium provide an automated testing infrastructure
• Can simulate user's interaction on angular application running in a browser or
mobile

JASMIN FRAMEWORK
● It’s a test syntax
● One or more it blocks describe the requirement of your
application
● Commands + expectation = it blocks
● Commands = do something with application
Navigate to a page
Click on a button
Expectation = assert something about the application's state
Value of the field
Current url
Expectation with an it block fails – runner mark it as “failed”
After each and before each

INSTALLATION
●Installed via Node Package Manager
npm install protractor
●Install Selenium Standalone Server
node_modules/protractor/bin/install_selenium_standal
one
Note: Require JDK(java development kit)
The webdriver-manager -helper tool to easily get an instance of a Selenium Server running
• webdriver-manager update
• webdriver-manager start
http://localhost:4444/wd/hub

WRITE A TEST
● Clean folder with
•spec file
•configuration file.
spec.js
describe('Protractor Demo App', function() {
it('should have a title', function() {
browser.get('http://juliemr.github.io/protractor-demo/');
expect(browser.getTitle()).toEqual('Super Calculator');
});
});
The describe and it syntax is from the Jasmine framework
browser - global created by Protractor

The Configuration File
exports.config = {
framework: 'jasmine',
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['spec.js'] ,
capabilities: {
browserName: 'firefox'
}
}
Chrome : default browser
RUN COMMAND : protractor config.js
RESULT : 1 tests, 1 assertion, 0 failures

INTERACTING WITH ELEMENTS
// spec.js
describe('Protractor Demo App', function() {
it('should add one and two', function() {
browser.get('http://juliemr.github.io/protractor-demo/');
element(by.model('first')).sendKeys(1);
element(by.model('second')).sendKeys(2);
element(by.id('gobutton')).click();
expect(element(by.binding('latest')).getText()).
toEqual('5');
// This is wrong!
});
});
<input type=text ng-model="first">.

Finding Elements in a Test
Use Selenium WebdriverJS Syntax:
ptor.findElement(protractor.By.x(‘...’));
or
ptor.findElements(protractor.By.x(‘...’));
findElement returns a single element, findElements returns an
array of elements.
Both will throw an exception if the locator cannot find the element
on the page

Protractor Locators
protractor.By.className('redBtn')
protractor.By.css('.redBtn')
protractor.By.id('loginButton')
protractor.By.linkText('Go Home')
protractor.By.partialLinktext('Home')
protractor.By.name('email')
protractor.By.tagName('h2')
protractor.By.xpath('')

Protractor Locators (cont)
protractor.By.binding('{{status}}')
protractor.By.select("user")
protractor.By.selectedOption("red")
protractor.By.input("user")
protractor.By.repeater("cat in pets")
protractor.By.repeater("cat in pets").row(1).column("{{cat.name}}"))

WebElement Methods
clear() If this element is a text entry element, this will clear the value.
click() Click this element.
getAttribute(name) Get the value of a the given attribute of the element.
getCssValue(propertyName) Get the value of a given CSS property.
getLocation() Where on the page is the top left-hand corner of the rendered element?
getSize() What is the width and height of the rendered element?
getTagName() Get the tag name of this element.

WebElement Methods (cont)
getText() Get the visible (i.e. not hidden by CSS) innerText of this element, including
sub-elements, without any leading or trailing whitespace.
isDisplayed() Is this element displayed or not? This method avoids the problem of having
to parse an element's "style" attribute.
isEnabled() Is the element currently enabled or not? This will generally return true for
everything but disabled input elements.
isSelected() Determine whether or not this element is selected or not.
sendKeys(keysToSend) Use this method to simulate typing into an element, which may set its value.
