💡 Hint

Common Mistakes

Using invalid class names that don't follow Java naming conventions.

Omitting the package declaration.

The class name should be descriptive and typically ends with 'Test'. 'SampleTest' is a common naming convention.

2fill in blank

medium

Complete the code to import the JUnit 5 test annotation.

JUnit

package com.example.tests;

import [1];

public class SampleTest {
    @Test
    void sampleTest() {
        // test code
    }
}

💡 Hint

Common Mistakes

Importing JUnit 4 annotations instead of JUnit 5.

Using incorrect package names.

JUnit 5 uses the package org.junit.jupiter.api for its annotations like @Test.

3fill in blank

hard

Fix the error in the package declaration to organize tests properly.

JUnit

package [1];

import org.junit.jupiter.api.Test;

public class SampleTest {
    @Test
    void sampleTest() {
        // test code
    }
}

💡 Hint

Common Mistakes

Using singular 'test' instead of plural 'tests'.

Using unrelated package names that don't reflect test purpose.

The package name should be plural 'tests' to follow common conventions for test packages.

4fill in blank

hard

Fill both blanks to create a package-info.java file with a test package description and annotation.

JUnit

import org.junit.platform.suite.api.SelectPackages;
/**
 * [1]
 */
@[2]("com.example.tests")
package com.example.tests;

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

AThis package contains unit tests

BThis package contains integration tests

CSelectPackages

DSelectClasses

💡 Hint

Common Mistakes

Using incorrect annotation names.

Writing unrelated package descriptions.

The package-info.java file documents the test package and uses the @SelectPackages annotation to specify the package for test discovery.

5fill in blank

hard

Fill all three blanks to define a test suite that runs all tests in the package.

JUnit

import org.junit.platform.suite.api.Suite;
import org.junit.platform.suite.api.[1];

@Suite
@[2]("com.example.tests")
public class [3] {
}

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

BSelectClasses

CAllTestsSuite

DTestSuite

💡 Hint

Common Mistakes

Using @SelectClasses instead of @SelectPackages for package-level suites.

Choosing unclear or inconsistent class names.

The suite uses @SelectPackages to include all tests in the package. The class name 'TestSuite' is a common name for such suites.
