About The Video
Check out this video to understand how to convert your test scripts from JUnit 4 to JUnit 5!
Upgrading from JUnit 4 to JUnit 5 offers numerous benefits, including a more flexible and extensible architecture. JUnit 5 supports modern development practices with features like dependency injection, dynamic tests, and more powerful assertions. It also integrates better with Java 8 and newer language features.
The new @TestFactory and @TestTemplate annotations enable dynamic and repeated tests. Additionally, JUnit 5 separates the API and platform, allowing for customization and support for multiple test engines improving overall test maintainability and flexibility.

Key Topics Covered
Manual Conversion Process:
Setup in IDE: Copy and rename the existing JUnit 4 test class, include junit-vintage-engine in pom.xml, and add JUnit 5 dependencies.
Updating Annotations: Replace JUnit 4 annotations with JUnit 5 equivalents (@BeforeClass to @BeforeAll, @Before to @BeforeEach, @After to @AfterEach, @AfterClass to @AfterAll). Update assertions to use JUnit 5's Assertions class.
Automatic Conversion Process:
Using IntelliJ IDEA: Use Control + Shift + A (Windows) or Command + Shift + A (Mac) to open the actions dialog and select "Migrate JUnit 4 to JUnit 5". Note: This updates annotations but not assertions.
Inspection Settings: Enable inspection for JUnit 4 to JUnit 5 migration in IntelliJ IDEA settings. Use the "migrate" option by placing the cursor in front of the class name and selecting the appropriate keys or hovering over the class name to initiate migration. Verify the changes using local history.
Verification:
Demonstrates how to verify changes by reviewing local history in the IDE. Shows updated import statements, annotations, and assertions.
Best Practices and Closing:
Summary of the conversion process. Emphasis on the benefits of JUnit 5, such as dynamic tests, better assertions, and separation of API and platform. Encouragement to adopt JUnit 5 for improved test maintainability and flexibility.
