You could potentially de-duplicate the first portion of the classpath by putting a string constant at the top and joining the path to the module with the remaining portion of the object path that is specific to the classpath. Or you could move the entire string to be a constant at the top and have the patch reference that constant. This way if you move the module, you only have to update 1 line in the test code. This generally is the dont-repeat-yourself principly (DRY).
