Sharing Test code in Maven

Question

How can you depend on test code from another module in Maven?

Example, I have 2 modules:

• Base
• Main

I would like a test case in Main to extend a base test class in Base. Is this possible?

Update: Found an acceptable answer, which involves creating a test jar.

Answer 1

I recommend using type instead of classifier (see also: classifier). It tells Maven a bit more explicitly what you are doing (and I've found that m2eclipse and q4e both like it better).

<dependency>
  <groupId>com.myco.app</groupId>
  <artifactId>foo</artifactId>
  <version>1.0-SNAPSHOT</version>
  <type>test-jar</type>
  <scope>test</scope>
</dependency>
