This error usually suggests that there’s a mismatch between the versions of JUnit dependencies you have configured in your Maven project. Let's break down the scenario further:

Dependencies will typically include various components such as junit-jupiter-api, junit-jupiter-engine, and junit-jupiter-params.

If the versions of these components do not align properly, it could lead to runtime exceptions like the one mentioned.

Understanding Dependency Management

In Maven, managing dependencies effectively is crucial to avoid such errors. When dealing with JUnit 5, it is recommended to use a Bill of Materials (BOM) approach, which helps ensure a consistent set of library versions.

Step-by-Step Solution
