Where should I put test support code for a Java library

Question

I have a Maven project which is used as a library in other projects. The setup is pretty standard: src/main with the library code, src/test with te

Answer 1

You can do this with the Maven Jar Plugin

Maven Jar Plugin

Since you're using Maven you can just cut a separate artifact of the project that contains the libraries you want to use in foo add the following plugin to create another jar artifact:

  
    org.apache.maven.plugins
    maven-jar-plugin
    2.3.2
    
       
          
              test-jar
          
       
    
  

This creates a second jar in this project of everything in the src/test directory.

Test Jars

You could splice out the stuff in that jar you don't need with some filters.

Then to use this library you would include this as a dependancy in foo:

 
    your.group
    parent-artifact-id
    1.0.0
    test-jar
    test
 

To separate the projects further you can also create a test only project with your more frameworky test jars.
