What’s In Store ?

Testing Automated testing Selenium WebDriver WebDriver API WebDriver for Google Chrome ChromeDriver ChromeDriver Architecture ChromeDriver Implementation Demo


Testing ?

Is the process of evaluating a system or its component(s) with the intent to find whether it satisfies what it needs to do.


Automated Testing

Testing a system or its component(s) with an use of an automation tool is called Automation testing.

In a Robotic way


Why Automation Testing ?

Automation does not require Human Intervention

Automation increases speed of test execution

Manual testing can be boring and hence error prone

Automation saves you money


Automation Tool Is a Software or a package that

allows you to use high level languages or keywords to create scripts on top of a test framework to manage the build and run of scripts that communicate with the Application under test

To control execution of tests To compare actual outcomes to

expected outcomes To report the status (PASS/FAIL)


Selenium WebDriver

Browser Automation Framework

It automates browser’s

http://docs.seleniumhq.org/


Selenium WebDriver

Selenium is an open Source tool and its free. Supports Cross Browser Testing. The Selenium tests

can be run on multiple browsers. Allows scripting in several languages like Java, C#,

Groovy, Ruby, PHP and Python. Assertion statements provide an efficient way of

comparing expected and actual results. Different browser implementations


Selenium Suite of Tools

Selenium IDE Selenium Remote Control (aka) Selenium 1.0

(Deprecated) Selenium WebDriver (aka) Selenium 2.0(aka)

WebDriver Selenium GRID


Selenium IDE

The Record and Playback tool


Why WebDriver ?

Because it’s a W3C Working Draft


WebDriver API

How does the WebDriver API looks like ?driver.findElement(By.name("q"))


UI Element Locators

We Human’s know what exactly to do on the web page, operations like click, double click…

Automation is a robotic process and we need instruct the bot to click ‘here’ by the element locators – the objects.

Different locatorsidcssxpathlinktext


Transformation from Manual to a Automated Tester


Manual Interaction Automated WebDriver API

Human Opens a browser and loads the URL of app under test

WebDriver driver = new ChromeDriver();driver.get(http://google.com);

Human Click on a button driver.findElement(By.linkText(”Google")).click();

Human types in a name in text field

driver.findElement(By.name("firstName")).clear();driver.findElement(By.name("firstName")).sendKeys(”gdgChennai");

Human selects an option from a dropdown

new Select(driver.findElement(By.id("glsel"))).selectByVisibleText("GB");

CHROMEDRIVER

Maintained and Developed by the Chromium Team at Google


Chromium

Browser Statistics


Interrogation

As a Web Developer, how can I automatically verify the critical functionality of my app works ?

As a Tester, how can I automatically verify the critical functionality of app under test performs what it supposed to do ?


ChromeDriverInteroperable with WebDriver Clients

Open source and maintained by the members of Chromium project


How does the test look like ?


How ChromeDriver works ?


ChromeDriver Implementation

Dev ToolsProvides access to internal of web app• Query and Manipulate DOM tree• Debugging JavaScript• Network Monitoring• Memory and Performance profiling

ExtensionsModify and enhance browser functionality• Window control


Detailed Architecture ViewChromeDriver


Chrome Extensions

Chrome Extensions can be either packed or unpacked.

Packed extensions are single file with a .crx extension Unpacked extensions are a directory containing the

extension, including a manifest.json file
