Integrating Selenium scripts with JMeter can significantly enhance your testing capabilities by combining functional and load testing. This article will guide you through the steps to achieve this integration successfully.
Possible Ways to Run Selenium Test Cases from JMeter
There are several methods to execute Selenium test cases within JMeter:
- Using JUnit Request Sampler
- Using BeanShell Sampler
- Using JSR223 Sampler with Groovy
1. JUnit Request Sampler
The JUnit Request Sampler method is beneficial if you want to reuse already automated Selenium scenarios instead of rewriting scripts for the WebDriver Sampler.
Setup
- Download the Selenium Java client libraries and add them to the JMeter classpath (e.g., %JMETER_HOME%/lib/).
- Ensure the Selenium server is running with the command:
java -jar selenium-server-standalone-${version}.jar - Export the Selenium test plan as a .jar file and save it to %JMETER_HOME%/lib/junit/.
Configuration
- Add a JUnit Request Sampler to your JMeter test plan.
- Set the Class Name and Test Method according to your Selenium test plan.
- Optionally, configure JMeter to search for JUnit 4 annotations by checking the appropriate checkbox.
Example Code
Here is an example of a JUnit 4 test class:
package com.example.tests;
import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class SeleniumTest {
private WebDriver driver;
@Before
public void setUp() {
driver = new FirefoxDriver();
driver.get("http://www.google.com/");
}
@Test
public void testGoogleSearch() {
Assert.assertEquals("Google", driver.getTitle());
}
@After
public void tearDown() {
driver.quit();
}
}
2. BeanShell Sampler
In this method, the Selenium test scenario is executed directly in JMeter’s BeanShell Sampler.
Setup
- Download the Selenium libraries and add them to the JMeter classpath.
- Start the Selenium server (if using Selenium RC).
Example Code
import com.thoughtworks.selenium.*;
import java.util.regex.Pattern;
Boolean result = true;
try {
selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://www.google.com/");
selenium.start();
selenium.windowMaximize();
selenium.open("/");
selenium.waitForPageToLoad("30000");
if (!selenium.isTextPresent("Google")) result = false;
} catch (Exception ex) {
ex.printStackTrace();
IsSuccess = false;
ResponseCode = "500";
ResponseMessage = ex.getMessage();
} finally {
selenium.stop();
}
IsSuccess = result;
return result;
3. JSR223 Sampler with Groovy
This method uses the JSR223 Sampler with Groovy for executing Selenium test scenarios, offering better performance than the BeanShell Sampler.
Setup
- Download the Selenium libraries and add them to the JMeter classpath.
- Download the latest Groovy binary distribution and add the groovy-all-${VERSION}.jar to %JMETER_HOME%/lib/.
- Restart JMeter.
Example Code
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
Boolean result = true;
try {
driver = new HtmlUnitDriver();
driver.setJavascriptEnabled(true);
driver.get("http://www.google.com/");
if (!driver.getTitle().contains("Google")) result = false;
} catch (Exception ex) {
ex.printStackTrace();
log.error(ex.getMessage());
SampleResult.setSuccessful(false);
SampleResult.setResponseCode("500");
SampleResult.setResponseMessage(ex.getMessage());
} finally {
driver.quit();
}
SampleResult.setSuccessful(result);
return result;
Conclusion
Integrating Selenium scripts with JMeter can provide a comprehensive testing solution, combining the strengths of functional and load testing. Each method described above offers unique advantages, and the choice of method will depend on your specific requirements and existing setup.
