This course examines the principles and practice of migrating the tests of a Java application from JUnit 4 to JUnit 5. This course will teach you how to make the migration in a systematic and organized way, addressing all testing levels.

There are a large amount of JUnit 4 tests written for present-day applications, but migrating to the latest version, JUnit 5, comes with many new features and annotations to utilize. In this course, Migrating from the JUnit 4 to the JUnit 5 Testing Platform, you’ll learn to move your JUnit tests from version 4, taking the advantages of the capabilities of version 5. First, you’ll explore the automated testing principles and concepts. Next, you’ll discover how to make the step from JUnit 4 to JUnit 5. Finally, you’ll learn how to move your tests to JUnit 5 at all levels (unit, integration, system, acceptance). When you’re finished with this course, you’ll have the skills and knowledge of the effective migration from JUnit 4 to JUnit 5 needed to move the existing applications to the version 5 approach of the JUnit framework.

Reviews summary

Systematic junit 4 to 5 migration guide

According to students, this course offers an incredibly well-structured and systematic approach to migrating tests from JUnit 4 to JUnit 5. Learners praise its comprehensive coverage, specifically noting how it addresses all testing levels, including unit, integration, system, and acceptance tests. Many describe the content as clear and practical, with engaging explanations that demystify the transition. Students highlight the hands-on demos and practical exercises as particularly invaluable, enabling them to apply lessons directly to their work. While largely positive, a few reviews suggest it might lack depth for highly advanced or complex legacy codebases, making it more suited for general professional migration needs rather than expert-level troubleshooting.

"I particularly appreciated the detailed examples covering all levels of testing – unit, integration, system, and even acceptance."
"The breakdown of migration by testing level is incredibly effective. It's comprehensive yet digestible."
"I liked the focus on different testing layers. It provides a practical roadmap."
Provides a clear, step-by-step guide for test migration.
"This course is incredibly well-structured for migrating from JUnit 4 to 5. It truly felt like a systematic guide."
"Very practical and to the point. The systematic approach to migrating tests at different levels... was exactly what I needed."
"Fantastic course! The systematic approach to migrating JUnit 4 tests to JUnit 5... is truly valuable."
Occasional small issues with provided code examples.
"My only minor gripe is that some of the initial setup steps could be a bit more explicit."
"I encountered a few minor issues with dependencies in the provided code examples which took a bit of time to resolve."
"There were a couple of instances where the code examples could have been debugged more thoroughly before release."
May not fully cover complex or expert-level migration scenarios.
"The course covers the basics, but I felt it lacked depth in certain advanced migration scenarios, especially concerning complex legacy codebases."
"I found the course helpful for getting started, but it felt a bit high-level for someone looking for really deep dives..."
"It's good for a general understanding but might not be enough for expert-level needs."
