[cmake-developers] Unit testing of new generators

[Josh Green]

Hi Brad,

Thanks for the quick response!

So let me see if I have this right....
I have the following development environment:
/dev/CMake -- checkout of CMake repo
/dev/build -- visual studio cmake projects
/dev/build-fastbuild -- the directory where I am generating fastbuild
projects into.

So, your instuctions are...
When generating the build directory, I should use:
/dev/build> cmake.exe ..\CMake -DBUILD_TESTING=ON

then I should build CMake using visual studio.
Once that is done, I should do the following:
/dev/build-fastbuild> ..\build\bin\debug\Cmake.exe -G Fastbuild ..\CMake
 -DCMake_TEST_EXTERNAL_CMAKE=/dev/build/bin/debug/Cmake.exe

then I should do the following:
/dev/build-fastbuild> ctest

is that right?
So what kind of tests will this run?
Is this documented anywhere?

Thanks

Josh
