JUnit Suite Test

Test suite

Test suite means bundle a few unit test cases and run it together. In JUnit, both @RunWith and @Suite annotation are used to run the suite test. This tutorial will show you an example having two TestJunit1 & TestJunit2 test classes to run together using Test Suite.

Create a Class

Create a java class to be tested say MessageUtil.java in C:\ > JUNIT_WORKSPACE

/** This class prints the given message on console.*/public class MessageUtil {   private String message;   //Constructor   //@param message to be printed   public MessageUtil(String message){      this.message = message;    }   // prints the message   public String printMessage(){      System.out.println(message);      return message;   }      // add "Hi!" to the message   public String salutationMessage(){      message = "Hi!" + message;      System.out.println(message);      return message;   }   }  	

Create Test Case Classes

Create a java class file name TestJunit1.java in C:\ > JUNIT_WORKSPACE

import org.junit.Test;import org.junit.Ignore;import static org.junit.Assert.assertEquals;public class TestJunit1 {   String message = "Robert";	   MessageUtil messageUtil = new MessageUtil(message);      @Test   public void testPrintMessage() {	      System.out.println("Inside testPrintMessage()");          assertEquals(message, messageUtil.printMessage());        }}

Create a java class file name TestJunit2.java in C:\ > JUNIT_WORKSPACE

import org.junit.Test;import org.junit.Ignore;import static org.junit.Assert.assertEquals;public class TestJunit2 {   String message = "Robert";	   MessageUtil messageUtil = new MessageUtil(message);    @Test   public void testSalutationMessage() {      System.out.println("Inside testSalutationMessage()");      message = "Hi!" + "Robert";      assertEquals(message,messageUtil.salutationMessage());   }}

Create Test Suite Class

• Create a java class.

• Attach @RunWith(Suite.class) Annotation with class.

• Add reference to Junit test classes using @Suite.SuiteClasses annotation

Create a java class file name TestSuite.java in C:\ > JUNIT_WORKSPACE to execute Test case(s)

import org.junit.runner.RunWith;import org.junit.runners.Suite;@RunWith(Suite.class)@Suite.SuiteClasses({   TestJunit1.class,   TestJunit2.class})public class JunitTestSuite {   }  	

Create Test Runner Class

Create a java class file name TestRunner.java in C:\ > JUNIT_WORKSPACE to execute Test case(s)

import org.junit.runner.JUnitCore;import org.junit.runner.Result;import org.junit.runner.notification.Failure;public class TestRunner {   public static void main(String[] args) {      Result result = JUnitCore.runClasses(JunitTestSuite.class);      for (Failure failure : result.getFailures()) {         System.out.println(failure.toString());      }      System.out.println(result.wasSuccessful());   }}  	

Compile all java classes using javac

C:\JUNIT_WORKSPACE>javac MessageUtil.java TestJunit1.java TestJunit2.java JunitTestSuite.java TestRunner.java

Now run the Test Runner which will run test case defined in provided Test Case class.

C:\JUNIT_WORKSPACE>java TestRunner

Verify the output.
