Hi,

You can use cmake for unit test as it supports GLib's test. I use
MonoDevelop/Xamarin Studio for developing for huge projects coexists
/w cmake (as MD/XS does not support cmake). MD is for rapid
development but there is no internal Unit to support vala but C#
(Nunit) and some other languages. So, I run some cmake command before
and after MD build which runs cmake for cmake build and run test. For
example:

before build: cmake .. in /build/ dir
after build in MD: run build/test/unit_test

I added CMakeLists.txt into my MD project and I just need to sync
betwwen MD and that file when I add or remove a Vala source file
into/from the MD.

I do not know how would it works /w launchpad as I do not know how its
packaging works /w cmake's unit test, but I think it should work.
You just need add some stanza in the project's root CMakeList.txt like
this, but it's not simpe as it's using some other features like
external projects and so on.
set (PROJECT_TEST tests)

...
enable_testing (true)
add_subdirectory (${PROJECT_TEST})

and add create some CMakeList.txt in the ./test dir

I am going to upload it to lp so, if you would like to have a look at
it just let me know and that case I will uploadid it on some day in
this week
