Resource files not found when running JUnit test

I'm having trouble running my JUnit test, it fails because it is not able to find the projects resources.

My test starts a server which loads all the needed resources using an URLClassLoader. I have no problem with the resources not being found when running my project otherwise. This problem only occurs when I try to run my JUnit test.

I have tried adding the file paths as arguments in my runtime configuration for the test like this, ex:

-cp .:/path/to/the/config/file

But it makes no difference.

Help please!

The convention in Maven is to have all Java test code in src/test/java. This is to prevent accidental inclusion of test code in the final product. So I suggest you move your tests.

Since you don't show the code which you use to load the resource, I can't tell you whether there are any bugs in that. But /path/to/the/config/file is most likely wrong; is must be /path/to/the/config so you can say in Java getClass().getClassLoader().getResource("file").

But I suggest to use a command line argument to specify the config file:

main(String[] args) {
    File configFile = new File(args[0]).getAbsoluteFile();
    if(!configFile.exists()) throw new IllegalArgumentException("Unable to find config file: " + configFile);
    ...
}

That makes error handling much more simple. Also, it allows to use different config files in tests and later in production.

Default Maven test path is src/test/java, so if your tests are not in that directory, you have to define your test path in pom.xml with tag <testSourceDirectory>, inside <build>. You have to include maven-surefire-plugin, too.
