How to deal with relative path in Junits between Maven and Intellij

Question

I have a maven project with a module

/myProject
pom.xml
    /myModule
    pom.xml
       /foo
       bar.txt

Consider a Junit in myModule

If you want to keep your code, you can try to change the working directory in the run/debug configuration (first entry in the combo box giving access to what you want to run) Set this to your module root. But prefer the other suggested approach:

ClassLoader.getSystemResourceAsStream(youPath) 

Or my preferred:

getClass.getResource(youPath)

or

getClass.getResourceAsStream(youPath)

A leading '/' in path indicates the working dir of your project, while no '/' indicates a relative dir to current class.

I use this last solution for my tests: I put my test data resources at the same package level as the test source, or in a subdir to avoid too messy package.

This way I can do a simple call without complicated path and without having to deal with working directory:

project-root  
  - module A  
    - src  
      - test
        - rootfile.txt  
        - my-complicated-package-naming-root
          - mypackage
            - Test.java
            - testResource.xml  

I can get the files this way:

final URL rootfile= Test.class.getResource("/rootfile.txt");
final URL testResource= Test.class.getResource("testResource.xml");
