1fill in blank

easy

Complete the code to mark the method that runs after each test.

JUnit

public class CalculatorTest {

    @Test
    public void testAdd() {
        // test code here
    }

    [1]
    public void cleanup() {
        System.out.println("Cleaning up after test");
    }

💡 Hint

Common Mistakes

Using @BeforeEach instead of @AfterEach

Using @AfterAll which runs only once after all tests

The @AfterEach annotation marks a method to be run after each test method in the class.

2fill in blank

medium

Complete the code to ensure the cleanup method runs after each test in JUnit 5.

JUnit

import org.junit.jupiter.api.[1];

public class SampleTest {

    @Test
    void testSomething() {
        // test logic
    }

    @AfterEach
    void cleanup() {
        System.out.println("Cleanup after test");
    }
}

💡 Hint

Common Mistakes

Importing @BeforeEach instead of @AfterEach

Forgetting to import the annotation

The import for @AfterEach is org.junit.jupiter.api.AfterEach to mark methods that run after each test.

3fill in blank

hard

Fix the error in the code to properly run cleanup after each test.

JUnit

public class TestExample {

    @Test
    public void testOne() {
        // test code
    }

    [1]
    public void cleanup() {
        System.out.println("Cleanup done");
    }
}

💡 Hint

Common Mistakes

Using @AfterAll which runs only once after all tests

Using @BeforeEach which runs before each test

The method should be annotated with @AfterEach to run after each test method.

4fill in blank

hard

Fill both blanks to create a test class with setup and cleanup methods running before and after each test.

JUnit

import org.junit.jupiter.api.[1];
import org.junit.jupiter.api.[2];

public class MyTest {

    @BeforeEach
    void setup() {
        System.out.println("Setup before test");
    }

    @AfterEach
    void cleanup() {
        System.out.println("Cleanup after test");
    }

    @Test
    void testMethod() {
        System.out.println("Running test");
    }
}

💡 Hint

Common Mistakes

Mixing up @BeforeEach and @AfterEach

Forgetting to import one of the annotations

The imports must include @BeforeEach and @AfterEach to mark setup and cleanup methods.

5fill in blank

hard

Fill all three blanks to create a test class with proper imports and an @AfterEach cleanup method.

JUnit

import org.junit.jupiter.api.[1];
import org.junit.jupiter.api.[2];
import org.junit.jupiter.api.[3];

public class CleanupTest {

    @BeforeEach
    void setup() {
        System.out.println("Setup before test");
    }

    @Test
    void testAction() {
        System.out.println("Test running");
    }

    @AfterEach
    void cleanup() {
        System.out.println("Cleanup after test");
    }
}
