How to write a completed Jmeter Test Plan for load testing using Jmeter API in Java

 Jmeter is excellent tool used to do load testing on the application. Jmeter has graphical(GUI) and Non graphical(Non GUI) options. Non graphical option use Jmeter API to write a complete test plan for loading testing in java.
Pre-prerequisites:
1. JMeter install somewhere.
2. Add JMeter jars from /lib and especially /lib/ext folders in your project or module class path.

Load the jmeter properties:

 //Set jmeter home for the jmeter utils to load  
 String jmeterHomelocation = "F:\\apache-jmeter-2.13\\";  
 String jmeterPropertieslocation = jmeterHomelocation + "bin\\jmeter.properties";  
   
 //JMeter Engine  
 StandardJMeterEngine jmeter = new StandardJMeterEngine();  
   
 //JMeter initialization (properties, log levels, locale, etc)  
 JMeterUtils.setJMeterHome(new File(jmeterHomelocation).getPath());  
 JMeterUtils.loadJMeterProperties(new File(jmeterPropertieslocation).getPath());  
 // see extra log messages of i.e. DEBUG level  
 JMeterUtils.initLogging();  
 JMeterUtils.initLocale();  

Create "Test Plan" Object and JOrphan HashTree:

 // JMeter Test Plan, basically JOrphan HashTree  
 HashTree testPlanTree = new HashTree();  
             
 // Test Plan  
 TestPlan testPlan = new TestPlan("Java code Test Plan");  
 testPlan.setProperty(TestElement.TEST_CLASS, TestPlan.class.getName());  
 testPlan.setProperty(TestElement.GUI_CLASS, TestPlanGui.class.getName());  
 testPlan.setUserDefinedVariables((Arguments) new ArgumentsPanel().createTestElement());  

Graphical: Thread Group
Right-click on the Test Plan > Add > Threads (Users) > Thread Group
Type below values in corresponding field
Number of Threads (users)   : 1
Ramp-Up Period (in seconds) : 1
Loop Count  : 1

 

Non Graphical: Thread Group

 // Thread Group  
 ThreadGroup threadGroup = new ThreadGroup();  
 threadGroup.setName("Test Thread Group");  
 threadGroup.setNumThreads(1);  
 threadGroup.setRampUp(1);  
 threadGroup.setSamplerController(loopCtrl);  
 threadGroup.setProperty(TestElement.TEST_CLASS, ThreadGroup.class.getName());  
 threadGroup.setProperty(TestElement.GUI_CLASS, ThreadGroupGui.class.getName());  

Graphical: Sampler

Right-click on the Thread Group > Add > Sampler > HTTP request
Write below values in corresponding field
Server Name or IP : hiromia.blogspot.com
Port NUmber       : 80
Path              : /

Non Graphical: Sampler

 HTTPSampler examplecomSampler = new HTTPSampler();  
 examplecomSampler.setDomain("www.google.com");  
 examplecomSampler.setPort(80);  
 examplecomSampler.setPath("/");  
 examplecomSampler.setMethod("GET");  
 examplecomSampler.setName("google");  
 examplecomSampler.setProperty(TestElement.TEST_CLASS, HTTPSampler.class.getName());  
 examplecomSampler.setProperty(TestElement.GUI_CLASS, HttpTestSampleGui.class.getName());  

Loop Controller:

 // Loop Controller  
  LoopController loopCtrl = new LoopController();  
  loopCtrl.setLoops(10);  
  loopCtrl.setFirst(true);  
  loopCtrl.setProperty(TestElement.TEST_CLASS, LoopController.class.getName());  
  loopCtrl.setProperty(TestElement.GUI_CLASS, LoopControlPanel.class.getName());  
  loopCtrl.initialize();  

Graphical: Summary Report
Right-click on the Thread Group > Add > Listener > Summary Report

Non Graphical: Summary Report

 Summariser summer = null;  
  String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");  
  if (summariserName.length() > 0) {  
    summer = new Summariser(summariserName);  
  }  
   
 // Store execution results into a .jtl file, we can save file as csv also  
  String reportFile = "report\\report.jtl";  
  String csvFile = "report\\report.csv";  
  ResultCollector logger = new ResultCollector(summer);  
  logger.setFilename(reportFile);  
  ResultCollector csvlogger = new ResultCollector(summer);  
  csvlogger.setFilename(csvFile);  
  testPlanTree.add(testPlanTree.getArray()[0], logger);  
  testPlanTree.add(testPlanTree.getArray()[0], csvlogger);  
   

Run Test Plan:

 // Run Test Plan  
 jmeter.configure(testPlanTree);  
 jmeter.run()

JMeter API has an option to run JMeter script which made by Jmeter GUI using java. StandardJMeterEngine is the 'heart' of JMeter. If you must execute a JMeter test from Java code, this is the best option. The absolute minimal code to read the existing .jmx file.
Pre-prerequisites:
1. JMeter install somewhere.
2. Add JMeter jars from /lib and especially /lib/ext folders in your project or module class path.

Build Jmeter load testing script using below steps:
1. Start Jmeter
Click on Jmeter_Home/bin/ApacheJMeter.jar or jmeter.sh to open Jmeter window

2. Add 'Thread Group' under 'Test Plan'
Right-click on the Test Plan > Add > Threads (Users) > Thread Group
Type below values in corresponding field
Number of Threads (users)   : 1
Ramp-Up Period (in seconds) : 1
Loop Count                  : 1

3. Add a Sampler under 'Thread Group'
Right-click on the Thread Group > Add > Sampler > HTTP request
Write below values in corresponding field
Server Name or IP : hiromia.blogspot.com

How to encode or encrypt password and other personal information in Selenium Webdriver using Java

Daily we sign in many popular websites like Facebook, Gmail, LinkedIn etc. with login credential. We need to send password as plain text to sign in those popular websites if want to write automation login script in selenium webdriver. One of the most common practice to send encrypted passwords and other personal information instead of plain text for the automation login script.

Base64: Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.

 byte[] encodedBytes = Base64.encodeBase64("TextforEncoding".getBytes());  
 System.out.println("encodedBytes " + new String(encodedBytes));  
 byte[] decodedBytes = Base64.decodeBase64(encodedBytes);  
 System.out.println("decodedBytes " + new String(decodedBytes));  

Prerequisite
1. Create a 'data.properties' file your project home directory

2. Download Base64 jar file and add jar file in project as external jar.

Demo Source code:

 import org.apache.commons.codec.binary.Base64;  
 import org.openqa.selenium.By;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.firefox.FirefoxDriver;

   private static By loginbutton = By.id("u_0_m");  
   
   public static void main(String[] arg) throws IOException {  
   
     // Create FileInputStream Object  
     FileInputStream fileInput = new FileInputStream(new File("data.properties"));  
     // Create Properties object  
     Properties prop = new Properties();  
     //load properties file  
     prop.load(fileInput);  
   
     // create Firebox object  
     WebDriver driver = new FirefoxDriver();  
     //Go to URL  
     driver.get("http://www.facebook.com");  
     //Maximize browser window  
     driver.manage().window().maximize();  
     //Set timeout  
     driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);  
   
     driver.findElement(email).clear();  
     driver.findElement(email).sendKeys(prop.getProperty("username"));  
   
     driver.findElement(password).clear();  
     driver.findElement(password).sendKeys(new String(Base64.encodeBase64(prop.getProperty("password").getBytes())));  
   
     driver.findElement(loginbutton).click();  
   
     //Print Encrypted Password  
     System.out.println("Encrypted Password =: " + new String(Base64.encodeBase64(prop.getProperty("password").getBytes())));  
     //Print Decrypted Password  
     System.out.println("Decrypted Password =: " + new String(Base64.decodeBase64(Base64.encodeBase64(prop.getProperty("password").getBytes()))));  
   
     //close firefox browser  
     driver.close();  
   }  
 }

How to operate new single window or multiple windows in selenium webdriver using java

Some Web application allows to login to their system using Gmail, Facebook, Twitter etc account. When click on Gmail, Facebook, Twitter, its icon button, new window open with a login page. Selenium webdriver provide opportunity to handle new opened window and back to original window after completing an operation on new window. In this tutorial I will show how to operate new window.

Switch between new opened windows and original window as below:

 
// Store the current window on String variable  
 String parentwindow = driver.getWindowHandle();  

 // Do the click operation that opens new window  
 // Switch to window that's your newly opened window  

 for(String winHandle : driver.getWindowHandles()){  
   driver.switchTo().window(winHandle);  
 }  

 // code to do something on new window  

 // Close the new window, if that window no more required  
 driver.close();  

 // Switch back to original browser (parent window)  
 driver.switchTo().window(parentwindow);  

 // Continue with original browser (parent window)  

Java demo source code:

 import org.openqa.selenium.By;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.firefox.FirefoxDriver;  
 public class Operatenewwindow {  
   public static void main(String[] arg) {  
     WebDriver driver = new FirefoxDriver();  
     driver.manage().window().maximize();  
     driver.get("http://localhost:8080/idea/a/community/login");  

     // Store the current window on String variable  
     String parentwindow = driver.getWindowHandle();  
 // Do the click operation that opens new window  
     driver.findElement(By.className("icon-facebook")).click(); 
 
 // Switch to window that's your newly opened window  
     for (String winHandle : driver.getWindowHandles()) {  
       driver.switchTo().window(winHandle);  
     }  

 // code to do something on new window  
     driver.findElement(By.id("email")).sendKeys("hiro@gmail.com");  
     driver.findElement(By.id("pass")).sendKeys("123456789");  
     driver.findElement(By.id("loginbutton")).click();  

 // Close the new window, if that window no more required  
     driver.close();  

 // Switch back to original browser (parent window)  
     driver.switchTo().window(parentwindow); 

 
 // Continue with original browser (parent window)  
     driver.close();

How to handle WebDriverException: Element is not clickable at point using java

Some case the element position is not fixed and we want to do some action like click button on that particular element then result an error as 'Exception in thread "main" org.openqa.selenium.WebDriverException: Element is not clickable at point (xx, yy). Other element would receive the click:'. This happens when the element is loaded into the DOM, but the position is not fixed on the UI. There can be some other divs or images or ads that are not loaded completely.

The different workable solutions provided below.
 1. Maximize browser window
 driver.manage().window().maximize();

 2. The page is getting refreshed before clicking on element.

 3. Scroll to element using Keys
driver.findElement(By.id("ID of the element")).sendKeys(Keys.PAGE_DOWN); 
 or
driver.findElement(By.id("ID of the element")).sendKeys(Keys.PAGE_UP);

4. Click on element using  Actions Class
WebElement element = driver.findElement(By.id("login-button"));
Actions action = new Actions(driver);
action.moveToElement(element).click().perform();

5. Page scroll up or down using JavaScriptExecutor
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(250, 0)"); // if the element is on top.
jse.executeScript("scroll(0, 250)"); // if the element is on bottom. 

6. Page move particular X or Y position using JavaScriptExecutor if element is not visible
 WebElement element = driver.findElement(By.id("login-button"));
JavascriptExecutor jse =(JavascriptExecutor)driver;
jse.executeScript("window.scrollTo(0,"element.getLocation().x+")");
element.click();
or
WebElement element = driver.findElement(By.id("login-button"));
JavascriptExecutor jse =(JavascriptExecutor)driver;
jse.executeScript("window.scrollTo(0,"element.getLocation().y+")");
element.click();
or
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("arguments[0].scrollIntoView()", driver.findElement(By.id("login-button"));

7.Element is not present at the time of execution. Use WebDriverWait to until the element is present.
WebDriverWait wait = new WebDriverWait(driver, 15);
wait.until(ExpectedConditions.elementToBeClickable(By.id("ID of the element")));

How to configure and run Selenium Grid

Selenium Grid : Selenium Grid is a component of Selenium that distributes multiple tests across different browsers, operating systems, and machines so that we can execute scripts in parallel. The selenium-server-standalone package includes Hub, WebDriver, and Selenium RC to execute the scripts in grid.

Selenium Grid has a Hub and a Node.
Hub :The hub is the central point  where the tests would be triggered. A Selenium Grid has only one Hub and it is launched on a single machine once.
Node :  Nodes are the Selenium instances that are linked to the Hub which execute the tests. There can be one or more nodes in a grid which can be launched on multiple machines with different platforms and browsers.

Prerequisite Software:

1. Download Eclipse
2. Download Selenium Standalone Server jar

3. The Internet Explorer Driver Server

4. Google Chrome driver for selenium webdriver

5. Opera driver for selenium webdriver

Installing TestNG for Eclipse:

Step 1 : Launch Eclipse and select Main Menu 'Help' --> 'Install New Software' .

Step 2 : Enter the URL as 'http://beust.com/eclipse' and click 'Add' .

Step 3 :  Enter the name as 'TestNG' on dialog box 'Add Repository' dialog box. and click 'OK'

Step 4 : Click 'Select All'

Step 5 : Click 'Next' to continue.

Step 6 :  Click 'Next'.

Step 7 : "Accept the License Agreement" and click 'Finish'.

Step 8 : Security Warning pops up as the validity of the software cannot be established. Click 'Ok'

Step 9 : The Installer prompts to restart Eclipse for the changes to take effect. Click 'Yes'.

Configuring the Hub:

Step 1 :  Port# 4444 must be free. The following below commandon Window command window to start the Hub by launching the Selenium Server. Now we will use the port '4444' to start the hub. 

java -jar selenium-server-standalone-2.53.0.jar -port 4444 -role hub -nodeTimeout 1000

Example: java -jar F:\Grid\selenium-server-standalone-2.53.0.jar -port 4444 -role hub -nodeTimeout 1000

Step 2 : Open desired browser and navigate to the URL http://localhost:4444 from the Hub

Step 3 : Click on 'console' link  --> click 'view config'. The config of the hub would be displayed as follows. As of now, we haven't got any nodes, hence we will not be able to see the details.

Configuring the Nodes: 

Step 1 : Start Firefox Node using the following below command.

java -jar 'the location of selenium server standalone jar' -role node -hub http://PC_IP:4444/grid/register -browser browserName=firefox -port port_number

Example:
java -jar F:\Grid\selenium-server-standalone-2.53.0.jar -role node -hub http://192.168.111.141:4444/grid/register -browser browserName=firefox -port 5555

 Step 2 : Launch Internet Explorer Node using the following below on command.
java -Dwebdriver.ie.driver='the location of IE driver' -jar 'the location of selenium server standalone jar' -role webdriver -hub http://PC_IP:4444/grid/register -browser browserName=ie,platform=WINDOWS -port port_number
Example: 
java -Dwebdriver.ie.driver=F:\Grid\IEDriverServer.exe -jar F:\Grid\selenium-server-standalone-2.53.0.jar -role webdriver -hub http://192.168.111.141:4444/grid/register -browser browserName=ie,platform=WINDOWS -port 5556 

 Step 3 : Launch Chrome Node using the following below on command.
java -Dwebdriver.chrome.driver='the location of chrome driver' -jar 'the location of selenium server standalone jar' -role webdriver -hub  http://PC_IP:4444/grid/register -browser browserName=chrome,platform=WINDOWS -port port_number
Example: 
java -Dwebdriver.chrome.driver=F:\Grid\chromedriver.exe -jar F:\Grid\selenium-server-standalone-2.53.0.jar -role webdriver -hub  http://192.168.111.141:4444/grid/register -browser browserName=chrome,platform=WINDOWS -port 5557 

Step 4 : After running the command, come back to the Hub. Navigate to the URL - http://pc_ip:4444 then Click on 'console' link ,  the Hub would now display Firefox, IE and chrome node attached to it.
