Unit Testing a classLoader gets NPE

[stef cris]

I am trying to unit test a path which I build with classLoader:

               final String resourcePath = this.getClass().getClassLoader().getResource("/res").getPath();
                path = resourcePath + templateFile.substring(16, templateFile.lastIndexOf('_') + 1) + FILEENDING;

I have no idea how to mock this classLoader, as it loads a class from another module.

Does anyone have any idea how could I mock it? Thank

this - can't be null
this.getClass() - can't be null
this.getClass().getClassLoader() - can't be null
this.getClass().getClassLoader().getResource(String) - can be null
So I would start there: What does getResource(String) actual gets you before calling .getPath() on it? Do a simple sysout to see if it's null. Progress from there onwards.
