Hi @siaeleni -

You should be able to do:

```auto
ModuleNameLogic().Test()

```

if you are in a different module file or in the python interactor you might need to call `import ModuleName` first.

(As an aside, the other ‘logic’ class `slicer.modules.moduleName.logic` is actually the C++ loadable module instance corresponding to the scripted module, but it’s really just an internal structure and doesn’t have any particular utility here).
