Maven Doesn't Find JUnit Tests: A Comprehensive Guide with Code Examples

Encountering issues where Maven isn't picking up and running your JUnit tests is a common frustration for Java developers. This comprehensive guide will walk you through potential causes, provide detailed solutions, and offer code examples to help you troubleshoot and resolve this problem. We'll cover everything from naming conventions and directory structures to dependency management and plugin configurations.

*Understanding the Core Problem*

Maven follows a convention-over-configuration approach. It expects your project to adhere to certain directory structures and naming conventions. When these conventions are not met, Maven's Surefire plugin (responsible for running tests) might not automatically discover and execute your tests.

*Common Causes and Solutions*

Here's a breakdown of the most frequent reasons why Maven might not find your JUnit tests and how to address them:

*1. Incorrect Directory Structure:*

*The Issue:* Maven expects your test classes to reside in the `src/test/java` directory. If your tests are located elsewhere, Maven won't automatically find them.
*The Solution:* Verify that your test classes are placed correctly under `src/test/java`.

*Example Project Structure:*



*Code Example (MyClass.java):*



*Code Example (MyClassTest.java):*



*2. Incorrect Naming Convention:*

*The Issue:* Maven's default Surefire plugin uses glob patterns to identify test classes. By default, it looks for classes ending with `Test` or `Tests` or starting with `Test`. If your test classes don't follow these patterns, Surefire won't recognize them.

*The Solution:* Rename your test classes to adhere to the naming convention. For example, `MyClassTest`, `MyClassTests`, or `TestMyClass`.

*Example (Correct Naming):*

`MyClassTest.java` (Correct)
`MyClassTests.java` (Correct)
`TestMyClass.java` (Correct)
`MyClassUnit.java` (Incor ...
