[Qgis-developer] How to debug and unit test Python plugins outside QGIS (e.g. in Ecplise IDE + PyDev)

[Stefan Keller]

Hi all

Regarding the initial thread: I finally managed to debug and unit test
Python plugins outside QGIS with Ecplise IDE and PyDev under Windows.
It's documented here (I'm sorry it's german and not yet english):
