Yes, I use the Eclipse CDT IDE. I set the properties of the test project 
to refer to the other project I am testing. This way, just hitting the 
build button for the test code automatically rebuilds the _tested_ code 
without requiring me to do anything!

The SOURCES += only works if the test code is in the same directory as 
the production code. They need to share the same OBJECTS directory.

Yes please, posting more detail is appreciated. Currently I am following 
the directory structure of QwtPlot with minor modifications. It works 
great for me, especially with the Eclipse CDT + Qt integration. I can 
import Qt projects using the (Import...) feature without moving the Qt 
projects from their places. This way I can develop in Eclipse and 
maintain a robust project tree in the same time.
