@Execution annotation in JUnit - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

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

JUnit

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

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

ATest

BBeforeEach

CExecution

DAfterAll

💡 Hint

Common Mistakes

Importing @Test instead of @Execution

Using annotations from JUnit 4 packages

The @Execution annotation is part of the org.junit.jupiter.api.parallel package in JUnit 5.

2fill in blank

medium

Complete the code to set the execution mode to concurrent using @Execution.

JUnit

@Execution(ExecutionMode.[1])
public class MyTests { }

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

ACONCURRENT

BSAME_THREAD

CSEQUENTIAL

DPARALLEL

💡 Hint

Common Mistakes

Using SAME_THREAD which runs tests sequentially

Using non-existent modes like PARALLEL

The ExecutionMode.CONCURRENT tells JUnit to run tests in parallel threads.

3fill in blank

hard

Fix the error in the annotation usage to correctly specify execution mode.

JUnit

@Execution(ExecutionMode.[1])
public class MyTests { }

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

ASAME_THREAD

Bparallel

Csame_thread

DCONCURRENT

💡 Hint

Common Mistakes

Using lowercase or snake_case instead of uppercase enum constants

Using invalid enum values

ExecutionMode enum constants must be uppercase and exactly as defined, like CONCURRENT.

4fill in blank

hard

Fill both blanks to import the ExecutionMode enum and use it to run tests in the same thread.

JUnit

import org.junit.jupiter.api.parallel.[1];
@Execution(ExecutionMode.[2])
public class SampleTest { }

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

AExecutionMode

BCONCURRENT

CSAME_THREAD

DExecution

Attempts:

3 left

💡 Hint

Common Mistakes

Importing Execution instead of ExecutionMode

Using CONCURRENT instead of SAME_THREAD

You must import ExecutionMode enum and use SAME_THREAD to run tests sequentially.

5fill in blank

hard

Fill all three blanks to create a test class that runs tests concurrently and imports both required annotations.

JUnit

import org.junit.jupiter.api.parallel.[1];
import org.junit.jupiter.api.[2];
@Execution(ExecutionMode.[3])
public class ConcurrentTests { }

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

AExecution

BTest

CCONCURRENT

DBeforeEach

💡 Hint

Common Mistakes

Forgetting to import @Test annotation

Using wrong execution mode values

Import Execution and Test annotations, then set execution mode to CONCURRENT for parallel tests.
