I'm currently working on unit tests for a game that I'm making and am running into a weird error with maven that I can't figure out.
I've run mvn clean and now my tests are failing.
Here is the error I get when I run mvn test -X:

}
I'm pretty sure it has something to do with the maven file but I am not sure what it is. Maybe something with the image reading library I am using? Any help would be greatly appreciated.
CodePudding user response：
The issue you're running into is that your test can't instantiate a Player (Line 24 of your test class). It'll fail to find the sprite resources when trying, and possibly have other failures if it's base class AnimateEntity is doing additional work.
Ideally, you should use a Mock object for use in your test cases. That way they aren't dependent on resources that may or may not be available.
If you absolutely need the resources to perform your tests, you need to configure maven to copy them to a target folder so that your tests can access them.
This link gives info on how to setup your project to use resources from a target directory.
