JUnit - Test suite

JUnit - Test suit

Test suite : bundle a few unit test cases and run it together.

* In JUnit, both @RunWith and @SuiteClasses annotation are used to run the suite test.

Below simple example explain how the test suite works in Junit.

1. TestJUnitMessageUtil.java

public class TestJUnitMessageUtil {

        private String message;

        /**

        * Constructor

        * @param message

        */

 

       public TestJUnitMessageUtil(String message){

              this.message = message;

       }

      //Print the message

      public String printMessage(){

              return this.message;

      }

      //Print the modified message

      public String printModifiedMessage(){

              return "Hi " + this.message;

      }

}

2. TestJUnit01.java

import org.junit.Assert;

import org.junit.Test;

public class TestJUnit01 {

          TestJUnitMessageUtil messageUtil = new TestJUnitMessageUtil("Sanjeeva");

 

          @Test

          public void testPrintMessage(){

                 Assert.assertEquals("Sanjeeva", messageUtil.printMessage());

          }

}

3. TestJUnit02.java

import org.junit.Assert;

import org.junit.Test;

public class TestJUnit02 {

           TestJUnitMessageUtil messageUtil = new TestJUnitMessageUtil("Sanjeeva");

           @Test

           public void testPrintMessage(){

                 Assert.assertEquals("Hi Sanjeeva", messageUtil.printModifiedMessage());

           }

}

4. TestSuite.java

import org.junit.runner.JUnitCore;

import org.junit.runner.Result;

import org.junit.runner.RunWith;

import org.junit.runner.notification.Failure;

import org.junit.runners.Suite;

import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)

@SuiteClasses({TestJUnit01.class,TestJUnit02.class})

public class TestSuite {

        public static void main(String[] args) {

               Result result = JUnitCore.runClasses(TestSuite.class);

               for (Failure failure : result.getFailures()) {

                      System.out.println(failure.toString());

               }

               System.out.println(result.wasSuccessful());

      }

}
