Execution order of lifecycle methods in JUnit - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

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

JUnit

@[1]
static void setupAll() {
    System.out.println("Runs once before all tests");
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using @BeforeEach instead of @BeforeAll

Forgetting to make the method static

The @BeforeAll annotation marks a method to run once before all tests in the class.

2fill in blank

medium

Complete the code to annotate a method that runs before each test method in JUnit 5.

JUnit

@[1]
void setup() {
    System.out.println("Runs before each test");
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using @BeforeAll instead of @BeforeEach

Making the method static (should be instance method)

The @BeforeEach annotation marks a method to run before each test method.

3fill in blank

hard

Fix the error in the code to correctly annotate a method that runs once after all tests in JUnit 5.

JUnit

@[1]
static void tearDownAll() {
    System.out.println("Runs once after all tests");
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using @AfterEach instead of @AfterAll

Not making the method static

The @AfterAll annotation marks a method to run once after all tests. The method must be static.

4fill in blank

hard

Fill both blanks to create a JUnit 5 test class with methods that run before all tests and after each test.

JUnit

import org.junit.jupiter.api.*;

public class ExampleTest {

    @[1]
    static void initAll() {
        System.out.println("Init before all tests");
    }

    @[2]
    void tearDown() {
        System.out.println("Cleanup after each test");
    }
}

Drag options to blanks, or click blank then click option'

CAfterEach

DAfterAll

💡 Hint

Common Mistakes

Mixing up @AfterEach and @AfterAll

Forgetting static on @BeforeAll method

@BeforeAll runs once before all tests, and @AfterEach runs after each test method.

5fill in blank

hard

Fill all three blanks to create a JUnit 5 test class with methods that run before each test, after each test, and once after all tests.

JUnit

import org.junit.jupiter.api.*;

public class LifecycleTest {

    @[1]
    void setup() {
        System.out.println("Before each test");
    }

    @[2]
    void cleanup() {
        System.out.println("After each test");
    }

    @[3]
    static void finish() {
        System.out.println("After all tests");
    }
}

💡 Hint

Common Mistakes

Using @BeforeAll instead of @BeforeEach for setup

Not making @AfterAll method static

@BeforeEach runs before each test, @AfterEach runs after each test, and @AfterAll runs once after all tests (method must be static).
