One of the issues I've had with creating a unit test for nsIProcess is figuring out the full path to my unit tests within the build system.
The answer is much simpler than I expected.
.getService(Components.interfaces.nsIProperties)
.get("CurProcD", Components.interfaces.nsIFile);
print(file.path);
This will return /home/james/mozilla/src/obj-ff/dist/bin which is exactly what I need.
The other issue is building a few simple executable files at compile time. I need binaries that do things like exit, never exit, and crash. (These are actually the files I need the full path for.)
Ted Mielczarek has pointed me in the right direction with regard to makefiles (which are my nemesis). Just write a TestProgram.cpp and then set SIMPLE_PROGRAMS = TestProgram in the makefile.
The only other stumbling block left is figuring out where the unit tests should go in the tree. I've been using the example file in the devmo tutorial. There is probably more makefile pain ahead.
