Java ignored test Case with JUnit: IgnoredTest example

Java Unit Test: Exercise-6 with Solution

Write a Java test case that is intentionally ignored, and explain the scenarios where test skipping might be useful.

Sample Solution:

Java Code:

// IgnoredTest.java

import org.junit.Test;
import org.junit.Ignore;
import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

public class IgnoredTest {

    public void testValidInput() {
        // Test implementation for valid input

    @Ignore("Test is ignored intentionally")
    public void testInvalidInput() {
        // Test implementation for invalid input

    public static void main(String[] args) {
        Result result = JUnitCore.runClasses(IgnoredTest.class);

        // Check if there are any failures
        if (result.getFailureCount() > 0) {
            System.out.println("Test failed:");

            // Print details of failures
            for (Failure failure : result.getFailures()) {
        } else {
            System.out.println("All tests passed successfully.");

Sample Output:

All tests passed successfully.


In the exercise above-

  • @Ignore Annotation: The "testInvalidInput" method is annotated with @Ignore. This annotation indicates that the test is intentionally ignored, and it provides an optional message explaining why the test is ignored.
  • Scenario where Test Skipping is Useful:
    • Incomplete Implementation: When a specific test is not fully implemented or is known to be incomplete, it can be marked as ignored until the implementation is complete.
    • Known Issues: If there are known issues with a particular test or if certain features are not yet available, the corresponding tests can be ignored until those issues are addressed.
    • Work in Progress: During development, when various parts of the codebase are in progress, developers might choose to ignore tests related to unfinished or experimental features.
    • Temporary Exclusion: In some scenarios, you might want to temporarily exclude a test from the test suite, perhaps to focus on other parts of the codebase without being distracted by known failing tests.
