The Difference Between junit-vintage-engine and junit-jupiter-engine
Last updated: January 8, 2024
Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.
Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservices, AI agents, and more.
With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Refactor Java code safely — and automatically — with OpenRewrite.
Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.
Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.
Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.

Regression testing is an important step in the release process, to ensure that new code doesn't break the existing functionality. As the codebase evolves, we want to run these tests frequently to help catch any issues early on.
The best way to ensure these tests run frequently on an automated basis is, of course, to include them in the CI/CD pipeline. This way, the regression tests will execute automatically whenever we commit code to the repository.
In this tutorial, we'll see how to create regression tests using Selenium, and then include them in our pipeline using GitHub Actions:, to be run on the LambdaTest cloud grid:
1. Overview
The JUnit testing framework is one of the most popular and widely used tools when testing Java applications. With the release of JUnit 5, two testing engines are now available for developers to choose from. However, there is some confusion about the junit-vintage-engine and the junit-jupiter-engine.
In this tutorial, we’ll explore the key differences between these two engines and discuss their advantages and disadvantages.
2. JUnit Vintage Engine
The junit-vintage-engine is designed for tests written in older versions of JUnit, such as JUnit 3 and JUnit 4. This engine provides backward compatibility with older versions of JUnit. Additionally, it allows using older tests while taking advantage of the new JUnit 5 features.
One of the key benefits of the junit-vintage-engine is the consistent testing environment for older tests. In addition, it works well in conjunction with the newer JUnit tests. This makes it easy to gradually migrate tests to JUnit 5 without doing a complete migration at once. The junit-vintage-engine also supports a wide range of test runners and frameworks, making it easy to integrate with existing development workflows.
However, there are some limitations to the junit-vintage-engine. It is designed for running tests written in older versions of JUnit. Thus, it does not support newer features and capabilities of JUnit 5, such as nested and parameterized tests. Additionally, some configurations and settings in the junit-jupiter-engine are unavailable in the junit-vintage-engine.
3. JUnit Jupiter Engine
The junit-jupiter-engine is the default testing engine in JUnit 5. It is designed to take advantage of the new capabilities of the JUnit 5 platform. This engine provides a wide range of testing styles and paradigms, including parameterized, nested, and dynamic tests, making it a highly versatile tool for testing Java applications.
One of the key benefits of the junit-jupiter-engine is its modular architecture, which makes it highly extensible and customizable. This means developers can easily add new features and functionality to the framework by writing custom extensions and plugins. The junit-jupiter-engine also provides a rich set of assertion methods that simplify testing various objects and data structures.
However, one potential drawback of the junit-jupiter-engine is that it may require additional setup and configuration compared to the junit-vintage-engine. This is particularly true if developers are migrating from older versions of JUnit. The junit-jupiter-engine may have problems running older tests written using the JUnit 3 or JUnit 4 frameworks.
4. Conclusion
When choosing between the junit-vintage-engine and the junit-jupiter-engine, developers should consider several factors: the age of the existing tests, the complexity of the testing environment, and familiarity with JUnit 5. Ultimately, the decision will depend on the project’s specific needs and requirements.
The JUnit 5 platform provides developers with a powerful and flexible framework for testing Java applications. By leveraging the strengths of both the junit-vintage-engine and the junit-jupiter-engine, we can create robust and reliable tests to ensure quality and reliability.
