Practice - 5 Tasks

1fill in blank

easy

Complete the code to mark a method that runs once after all tests in a JUnit 5 test class.

JUnit

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

public class CalculatorTest {

    @[1]
    static void cleanup() {
        System.out.println("Cleanup after all tests");
    }
}

Common Mistakes

Using @AfterEach instead of @AfterAll

Not making the method static

The @AfterAll annotation marks a method to run once after all tests in the class have finished.

2fill in blank

medium

Complete the code to ensure the @AfterAll method is static as required by JUnit 5.

JUnit

import org.junit.jupiter.api.AfterAll;

public class DatabaseTest {

    @AfterAll
    [1] closeConnection() {
        System.out.println("Closing DB connection");
    }
}

Common Mistakes

Omitting static keyword

Making method non-static with @AfterAll

In JUnit 5, @AfterAll methods must be static unless using a test instance lifecycle that allows non-static.

3fill in blank

hard

Fix the error in the @AfterAll method declaration to make it valid in JUnit 5.

JUnit

import org.junit.jupiter.api.AfterAll;

public class ServiceTest {

    @AfterAll
    public [1] cleanup() {
        System.out.println("Service cleanup");
    }
}

Common Mistakes

Using non-void return types

Returning values from @AfterAll methods

@AfterAll methods must have void return type because they are lifecycle hooks, not test methods.

4fill in blank

hard

Fill both blanks to correctly define an @AfterAll method that prints a message and is static.

JUnit

import org.junit.jupiter.api.AfterAll;

public class NetworkTest {

    @AfterAll
    [1] [2] cleanupNetwork() {
        System.out.println("Network cleanup done");
    }
}

💡 Hint

Common Mistakes

Forgetting static keyword

Using non-void return type

The method must be static and have void return type to be a valid @AfterAll method.

5fill in blank

hard

Fill all three blanks to create a valid @AfterAll method with public visibility, static modifier, and void return type.

JUnit

import org.junit.jupiter.api.AfterAll;

public class FileTest {

    @AfterAll
    [1] [2] [3] cleanupFiles() {
        System.out.println("Files cleaned up");
    }
}

💡 Hint

Common Mistakes

Using private or default visibility

Omitting static keyword

Using non-void return type

A valid @AfterAll method is usually public, static, and void to be accessible and run after all tests.
