@Order for execution order in JUnit - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the execution order of the test method using @Order.

JUnit

@Test
@Order([1])
void testFirst() {
    // test logic here
}

💡 Hint

Common Mistakes

Using 0 or negative numbers.

Omitting the @Order annotation and expecting order.

The @Order annotation takes an integer value to specify the order. Lower numbers run first. Use '1' for the first test method.

Complete the code to import the correct package for the @Order annotation.

JUnit

import [1];

@Test
@Order(2)
void testSecond() {
    // test logic
}

💡 Hint

Common Mistakes

Importing @Order from the wrong package causing compilation errors.

Confusing @Order with @Test import.

The @Order annotation is part of the JUnit Jupiter API package 'org.junit.jupiter.api.Order'.

Fix the error in the test class to ensure methods run in the specified order.

JUnit

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.TestMethodOrder;
import org.junit.jupiter.api.MethodOrderer.OrderAnnotation;

@TestMethodOrder([1].class)
class MyTests {

    @Test
    @Order(1)
    void firstTest() {}

    @Test
    @Order(2)
    void secondTest() {}
}

💡 Hint

Common Mistakes

Using @Order instead of OrderAnnotation in @TestMethodOrder.

Using MethodOrderer.class which is an interface, not a class.

The @TestMethodOrder annotation requires a class that implements MethodOrderer. 'OrderAnnotation.class' is the correct class to specify ordering by @Order.

4fill in blank

hard

Fill both blanks to create a test class that runs testOne first (@Order(1)), then testThree (@Order(3)).

JUnit

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.TestMethodOrder;
import org.junit.jupiter.api.MethodOrderer.OrderAnnotation;

@TestMethodOrder([1].class)
class OrderedTests {

    @Test
    @Order([2])
    void testOne() {}

    @Test
    @Order(3)
    void testThree() {}
}

💡 Hint

Common Mistakes

Using wrong class in @TestMethodOrder.

Setting @Order values incorrectly causing wrong execution order.

Use @TestMethodOrder(OrderAnnotation.class) to enable ordering by @Order. The testOne method should have @Order(1) to run before testThree with @Order(3).

5fill in blank

hard

Fill all three blanks to define a test class with three tests running testFirst (@Order(1)) first, testSecond (@Order(2)), then testThird (@Order(3)).

JUnit

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.TestMethodOrder;
import org.junit.jupiter.api.MethodOrderer.OrderAnnotation;

@TestMethodOrder([1].class)
class MultiOrderTests {

    @Test
    @Order([2])
    void testSecond() {}

    @Test
    @Order([3])
    void testThird() {}

    @Test
    @Order(1)
    void testFirst() {}
}

💡 Hint

Common Mistakes

Mixing up order numbers causing unexpected test execution order.

Forgetting to use OrderAnnotation.class in @TestMethodOrder.

Use @TestMethodOrder(OrderAnnotation.class) to enable ordering. Set @Order(2) for testSecond and @Order(3) for testThird so the execution order is testFirst(1), testSecond(2), testThird(3).
