Selenium – An IntroSelenium Tool’s SuiteSelenium RC (Versus) Selenium WebDriverWhat’s new? - Selenium WebDriverAdvanced concepts in WebDriverDemo

What is Selenium?

• Selenium is a set of different software tools for automating web applications.

• Can be used for most of the browser/platform combinations.

• Supports many languages including Ruby, Python, Java etc.

• Open source and free.

Selenium’s Tool Suite

• Selenium IDE.• Selenium RC.• Selenium 2.0 (WebDriver).• Selenium Grid.

Selenium RC

Selenium WebDriver

Advantages of WebDriver

One should use WebDriver when requiring improved support for

* Multi-browser testing including improved functionality for browsers not well-supported by Selenium-1.0.* Handling multiple frames, multiple browser windows, popups, and alerts.* Page navigation.* Drag-and-drop.* AJAX-based UI elements.

Advancing in WebDriver

Using Java/JQuery scripts Retrieving Java script errors Identifying broken links Handling ‘Wait’ in WebDriver Reporting Server-client responses Reporting Page load timings Cross browser testing

Using Java/JQuery ScriptsSelenium WebDriver 2.0 provides us an Interface ‘JavaScriptExecutor’ to execute JS/Jquery scripts independent or within the application

JavascriptExecutor js = (JavascriptExecutor) driver;

js.executeScript("alert('Hello from Selenium!');");

Retrieving JavaScript Errors

Identifying JSErrors Cross Browser

For Firefox :We have to add an plugin

“JSErrorCollector.xpi” in Firefox profile which aids to identify the Java script errors on the page and the same could be retrieved using JavaScriptErrorCollector API.

List<JavaScriptError> jsErrors = JavaScriptError.readErrors(driver);

Other Browsers:For Other Browsers: We need to add the below code in our application

and use JavaScript query to retrieving the details<script type="text/javascript">

window.onerror=function(msg){

var previous_errors = document.getElementsByTagName("body")[0].getAttribute("JSError");

$("body").attr("JSError",previous_errors + '\n' + msg );

}

</script>

Broken Links

Handling ‘Wait’ in WebDriver

Fluent Wait (withTimeOut, Polling mechanism)

Implicit Wait (withTimeOut)

Ajax load Wait (Developed through JQuery for verifying AJAX calls)

HAR (Http Archive Report)

• Exports HTTP tracing information for performance analytics

Data from HAR file

How long it takes to fetch the DNS information

How long each object takes to be requestedHow long it takes to connect to the serverHow long it takes to transfer from the

server to the browser of each objectWhether the object is blocked or not

Cross Browser Testing with Grid 2.0

SikuliWebDriver

SikuliFirefoxDriver extends Selenium's FirefoxDriver by adding Sikuli's image search capability. It is useful for automating interactions with highly visual interfaces such as Google Map.

“Testing is an infinite process of comparing the invisible to the ambiguous in order to avoid the unthinkable happening to the anonymous.” - James Bach
