Selenium Integration With Jmeter...

Is Jmeter capable of doing Performance testing of an application with Selenium Scripts..?

Answer is yes, this is possible with Jmeter and Selenium Scripts written over in Junit.

• Jmeter is having set of samplers of doing Different operations. For Integration we have sampler Known as "Junit Request", this can be used to execute tests written in Junit 3 or junit4 (Selenium)
• A test Script written junit4 uses Junit annotations, below is the example of the Scripts which is written in Selenium Junit 4

For Total Script click on this Link....... Selenium_JunitScript

Once the Scripting is done , Export them as jar files .To export to jar files right click on the project folder -> select Export-> Expand Java folder -> Click on Jar files -> Click next -> select the resources to export -> check the option “Export java source files and resources”-> Choose destination -> finish

Copy the Jar file and paste it in the Junit folder under lib folder of Jmeter. Here is the path in my system “D:\apache-jmeter-2.9\lib\Junit”.

Before proceeding further, Download Selenium Standalone Server at this location “https://code.google.com/p/selenium/downloads/detail?name=selenium-server-standalone-2.39.0.jar”

• Copy the Selenium Standalone server jar file to the lib folder of Jmeter
• Now open Jmeter, Create a Thread group{right click on testplan-> Select ADD-> Select Thread(users)-> Select Thread Group}
• Create a "junit Request"{Right click on Thread Group-> Select Add-> Select Sampler-> Select Junit Request}
  

In the two drop downs (Marked as red) one could be the tests that are created using Junit4 i.e. by extending the Test Case class (Classname)

-          In order to see the tests that are created using Junit annotations, just check the check box “Search for Junit4 annotations” and drop downs would populated accordingly

-          Add the listeners to see the results{Right click on Thread group->Select Add-> Select Listener}

-          Select the test method we want to execute from the “Test Method” drop down and run the test(press Ctrl+R)

-          It will launch the browser and perform the actions as per the test scripts.

-          And finally we can view the results in the listeners. “View result tree in Table” and standard Deviation, Throughput, Mean, Average, Minimum and Maximum time that the samples took to execute could be noted from the “Summary/ Aggregate” reports.

The results are looks like below.........    :)

Wait for the element Present in Selenium WebDriver(Explicit Wait)

In General , in Slenium Webdriver we have  two types of wait commands are available. implicit wait and explicit wait. 

 implicit wait :
It's global setting applicable for all elements and if element appear before specified time than script will start executing otherwise script will throw NoSuchElementException.  

    Thread.sleep() - It will sleep time for script, not good way to use in script as it's sleep without condition.

driver.manage().timeouts().implicitlyWait(120,TimeUnit.SECONDS)


explicit wait:  Wait for the element to be present

WebDriverWait explicit=new WebDriverWait(driver, 10);   // 10 in secs 

explicit.until(ExpectedConditions.visibilityOfElementLocated(By.id("element id"))).click();

Selenium WebDriver... Multiple Windows(Child Window and Parent Window)

For Navigating to child window form parent window, can use below command...

String Parent_Window = Driver.driver.getWindowHandle();

  for (String Child_Window : Driver.driver.getWindowHandles()) {

   Driver.driver.switchTo().window(Child_Window);

  }
