JUnit - Ignore Test

Sometimes it so happens that our code is not completely ready while running a test case. As a result, the test case fails. The @Ignore annotation helps in this scenario.
A test method annotated with @Ignore will not be executed.
A test method annotated with @Ignore will not be executed.
If a test class is annotated with @Ignore, then none of its test methods will be executed.
If a test class is annotated with @Ignore, then none of its test methods will be executed.
Now let's see @Ignore in action.
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 a java test class, say, TestJunit.java.
Create a java test class, say, TestJunit.java.
Add a test method testPrintMessage() or testSalutationMessage() to your test class.
Add a test method testPrintMessage() or testSalutationMessage() to your test class.
Add an Annotaion @Ignore to method testPrintMessage().
Add an Annotaion @Ignore to method testPrintMessage().
Create a java class file named TestJunit.java in C:\ JUNIT_WORKSPACE.
import org.junit.Test;
import org.junit.Ignore;
import static org.junit.Assert.assertEquals;

public class TestJunit {

   String message = "Robert";	
   MessageUtil messageUtil = new MessageUtil(message);
   
   @Ignore
   @Test
   public void testPrintMessage() {
      System.out.println("Inside testPrintMessage()");
      message = "Robert";
      assertEquals(message,messageUtil.printMessage());
   }

   @Test
   public void testSalutationMessage() {
      System.out.println("Inside testSalutationMessage()");
      message = "Hi!" + "Robert";
      assertEquals(message,messageUtil.salutationMessage());
   }
	
}
Create a java class file named 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(TestJunit.class);

      for (Failure failure : result.getFailures()) {
         System.out.println(failure.toString());
      }
		
      System.out.println(result.wasSuccessful());
   }
}  	
Compile the MessageUtil, Test case and Test Runner classes using javac.
C:\JUNIT_WORKSPACE>javac MessageUtil.java TestJunit.java TestRunner.java

Now run the Test Runner, which will not run the testPrintMessage() test case defined in the provided Test Case class.
C:\JUNIT_WORKSPACE>java TestRunner

Verify the output. testPrintMessage() test case is not tested.
Inside testSalutationMessage()
Hi!Robert
true

Now, update TestJunit in C:\>JUNIT_WORKSPACE to ignore all test cases. Add @Ignore at class level.
import org.junit.Test;
import org.junit.Ignore;
import static org.junit.Assert.assertEquals;

@Ignore
public class TestJunit {

   String message = "Robert";	
   MessageUtil messageUtil = new MessageUtil(message);
     
   @Test
   public void testPrintMessage() {
      System.out.println("Inside testPrintMessage()");
      message = "Robert";
      assertEquals(message,messageUtil.printMessage());
   }

   @Test
   public void testSalutationMessage() {
      System.out.println("Inside testSalutationMessage()");
      message = "Hi!" + "Robert";
      assertEquals(message,messageUtil.salutationMessage());
   }
	
}
Compile the test case using javac.
C:\JUNIT_WORKSPACE>javac TestJunit.java

Keep your Test Runner unchanged as follows −
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(TestJunit.class);
		
      for (Failure failure : result.getFailures()) {
         System.out.println(failure.toString());
      }
		
      System.out.println(result.wasSuccessful());
   }
}
Now run the Test Runner, which will not run any test case defined in the provided Test Case class.
C:\JUNIT_WORKSPACE>java TestRunner

Verify the output. No test case is tested.
true
