Ever looked for a comprehensive intro to JUnit 5 that is fun and entertaining at the same time? Then have a look at this brand-new episode of "Marco Codes": JUnit 5 Tutorial [Crash Course].

In this video, you'll learn how to use JUnit 5 like a professional. Understand what Maven/Gradle dependencies you'll need, how to write tests, how to use other assertion libraries like AssertJ and asserting JSON & XML, and explore new JUnit 5 features like @ParameterizedTests, @TestFactorys, and @ExtendWith. By the end of the tutorial, there won't be many questions left when it comes to JUnit 5.

Marco Codes

A comprehensive crash course on JUnit 5 covering setup with Maven, writing unit tests, using AssertJ for fluent assertions, JSON and XML assertions with JsonUnit and XmlUnit, the JUnit lifecycle (@BeforeEach, @AfterEach, @BeforeAll, @AfterAll), parameterized tests with value sources and CSV file sources, dynamic tests via @TestFactory, test tagging for CI/CD filtering, and integrating third-party extensions like Mockito using @ExtendWith.
