SELENIUM VS. QTP JOB TRENDS

GRIDFUSION.NET5

A FEW THOUGHTS ON TEST AUTOMATION

● Manual testing is still very important● E2E tests are expensive, so keep them to the minimum● Automation is software development● Be careful with record & playback tools● Automate the repetitive tasks (regression)● Build testability into your product● ROI...● More at http://gridfusion.net/thoughtsonautomation.html

SELENIUM AUTOMATES BROWSERS

THAT'S IT

... kind of

Selenium is becoming a W3C standard: http://www.w3.org/TR/webdriver

GRIDFUSION.NET8

SELENIUM FLAVORS

Selenium IDE

Selenium RC(deprecated)

WebDriver

Selenium GRID

GRIDFUSION.NET9

SELENIUM IDE

What it is:– First Selenium experience for many people– Firefox add-on– Record & playback solution– Not maintainable

What it is for:– Quick reproduction of scenarios & bugs– Products with few testcases & low change frequency– Help to write the „real tests“ – Find ID's / XPATH etc.

GRIDFUSION.NET11

SELENIUM (WEBDRIVER)

What it is :– Web testing tool– Highly successful open source project – Stable

Technical :– Protocol describing the user interactions– Supports most browser implementations– Support for most common programming languages

GRIDFUSION.NET12

WHAT IT IS NOT

- a drag & drop tool

- a network testing / monitoring tool

- a performance testing tool

- a reporting tool

2 PIECES

client serverjson wire protocol

GRIDFUSION.NET14

CLIENT

● What testers "see" as selenium● It doesn't "do" anything except generates Http requests

that will be handled by the server

● It is the part that will be called :– By the test framework– By the CI server

● Officially supported languages: java, c#, python,ruby

● Not officially supported : perl, php, js

GRIDFUSION.NET15

SERVER

● Where all the action happens● Where the contributors spend their time● Drives the browser under test

● Supported by the Selenium team: IE, Firefox, Safari

● Supported by vendors: Chrome, Opera

TESTS

Tests are java executable code and can be run:

– Manually from a personal machine, using an IDE

– Automatically from a continuous integration server

GRIDFUSION.NET18

TEST EXAMPLE

@Testpublic void localBrowserTest() throws MalformedURLException{

System.out.println("starting test");

DesiredCapabilities capability = DesiredCapabilities.chrome();WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

driver.get("http://www.digicomp.ch");

WebElement searchBox = driver.findElement(By.id("q"));searchBox.sendKeys("Selenium");

WebElement go = driver.findElement(By.className("submitsearch"));go.click();

Assert.assertEquals(driver.getTitle(), "Digicomp");

System.out.println("Page Title: " + driver.getTitle());

driver.quit();

}

GRIDFUSION.NET19

GRID

● Scale● Run tests in parallel ● Reduce test execution times● Crossover Tests (Web, Mobile, Desktop)

PUTTING IT INTO ACTION (WITHOUT GRID)

Start the Selenium Server– java -jar selenium-server-standalone-x.y.z.jar

PUTTING IT INTO ACTION WITH GRID

Start the Selenium GRID hub– Java -jar selenium-server-standalone-x.y.z.jar -role hub– Check: http://ipaddress:4444/grid/console

Start a Selenium Node & register with the hub

– java -jar selenium-server-standalone-x.y.z.jar -role node -hub http://ipaddress:4444/grid/register

OR to specify Browser / OS

– java -jar selenium-server-standalone-x.y.z.jar -role node -hub http://ipadress:4444/grid/register -browser browserName=firefox,maxInstances=4,platform=LINUX

MOBILE

● Mobile automation should be compatible / similar to Web automation

● Mobile Web automation is less of a problem● Native App automation is more difficult● Mobile Web: android-driver / iphone-driver● Native apps: calabash-driver, ios-driver

GRIDFUSION.NET27

IOS-DRIVER

● Implements the JSON wire protocol● Runs on emulators and devices● Can be run as a regular node in a Selenium Grid● No need to change the source● No need to jailbreak the device● No ios-driver app to install on the phone● http://freynaud.github.com/ios-driver/

GRIDFUSION.NET28

WHY ALL IN ONE GRID ?

● Web and mobile are converging● Users are moving between devices (i.e. Web

(in the office) -> Android Phone (on the train) -> iPad (at home on the couch)

● Need to ensure consistent user experience and functionality

GRIDFUSION.NET31

PAGE OBJECTS

•http://code.google.com/p/selenium/wiki/PageObjects

•Page objects model the pages and page interactions

•Reduce code duplication

•Reduce maintenance effort

•Easy international support

•Public methods represent the service of a page

GRIDFUSION.NET33

WHY OPEN SOURCE?

● Accelerator for innovation● Independence from vendors ● Worldwide support and contributions● It is free (...kind of) ● Motivator for employees ● External recognition for employees
