Integration of Junit test with Jmeter

In this post I will show you how to integrate and execute Junit test with Jmeter .

Junit test:

Here I have created two Junit test:
1. JunitFirstTest.java:

package com.test;

import org.junit.*;

public class JunitFirstTest {

    @BeforeClass

    public static void beforeClassAnnotation() {        

         System.out.println("@BeforeClass - for junit class 1");

    }

    @AfterClass

    public static void afterClassAnnotation() {       

         System.out.println("@AfterClass - for junit class 1");

    }  

    @Test

    public void testAnnotation() {       

        System.out.println("@Test - first class test method");

    }    

}

2. JunitSecondTest.java:

package com.test;

import org.junit.*;

public class JunitSecondTest {

    @BeforeClass

    public static void beforeClassAnnotation() {        

         System.out.println("@BeforeClass - for junit class 2");

    }

    @AfterClass

    public static void afterClassAnnotation() {       

         System.out.println("@AfterClass - for junit class 2");

    }  

    @Test

    public void testMethod2() {       

        System.out.println("@Test - Second class test method");

    }    

}

Note: add suffix “Test” in class name of your junit test

Creating Jar file:

Compile your all junit test and put all compiled (.class) file and .java file into package what your junit test have.  As above junit test have package “com.test” so we need to create “com\test” folder and put all junit  .java and .class file in this folder. See as in below screen:

Open command prompt and goto root folder as I “E:\Junit-Test”. Run below command to create jar file for the same.

jar cvf Jmeter-Junit.jar *.*

You should see “Jmeter-Junit.jar” file is created. 

Integration with Jmeter:

Put this jar file under your Jmeter “lib>>junit” folder. 

Go to bin folder and launch Jmeter. 

Create Thread group in Jmeter, right click on “Thread Group” and create Junit test request.

Click on check box “Search for Junit 4 annotation (Instead of Junit 3) if your test is in Junit 4. Your Junit test classes listed as below screen:

Now you are ready to create and execute Jmeter test of your Junit scripts.
