The scenario described could be improved by allowing the helper to be injected into the service, which is generally a better idea. However, to address the question as asked, you can get there using runtime metaprogramming. The specifics my depend on factors not expressed in the question but you can do something like this in the test...

UtilClass.metaClass.utilFunc = { ->
    // put your test behavior here...
}
