Where to store a binary file to be used for unit testing

Where should I store a resource (binary file in my case) that I need to use for unit testing?

Specifically, my directory structure is a standard:

src -> main -> java -> com.company.project -> classes...
    -> test -> java -> com.company.project -> classes...

I want to mock a file being read from the file system and replace it with a file from within my project.

Solution

  • src\test\resources is a good place for resources you need for unit-testing, if you are using mavens standard directory layout.
