Writing JUnit test app to test a method which uses AppResources

Question

Recently I was given a requirement to write a JUnit class( with main) to test a method in a Processor class which is running in weblogic. But this method in processor class makes use of AppResources like this: AppResources appResources = new AppResources("ApplicationResources"); String ruleFileName = appResources.getResourceString("rule.file.irlfile"); But when I try to run my JUnit test (stand alone app with main class) I am getting "java.util.MissingResourceException: Can't find bundle for base name ApplicationResources" exception. The appResources is null... Any ideas how to work around this problem?

It doesn't sound like the Process class was designed for testability outside of its J2EE server container, probably. So writing a unit test for it, under its current design, may be an exercise in futility. You might want to look into "Cactus" tests (search for JUnit Cactus on the web), to test it in its container. Or, redesign the class for testability, separating its business logic better (that's a lot of work to do though) so that it can be instantiated and exercised independently of its environment.
