I am learning Python Toolboxes with PyScripter.
I have a test python toolbox that outputs a raster file. It works when run from ArcCatalog.
As I understand it, it should also run standalone within Pyscripter but when I run it, no output appears in the Python Interpreter, and no file is created in the target geodatabase. I also can't locate advice on how to make the messages appear within the Pyscripter window, as they do in ArcCatalog, eg to indicate the analysis has finished within PyScripter without having to check in ArcCatalog.
Any advice / ideas would be appreciated.
I am using ArcGIS Desktop 10.2.2
