Both init() and init_and_watch() will throw an exception if they
fail initializing Log4perl -- they're not returning a meaningful
return code.

For your test suite, you might want to check sucess by using eval{}:

    eval {
        Log::Log4perl->init_and_watch(...);
    };

    if($@) {
        # Error!
    } else {
        # Success!
    }
