The tests can be in d3dcompiler, even though they may depend on a
specific D3D version for verifying the results. The d3dcompiler dll
itself is D3D version agnostic, but the produced shader bytecode not
so much. For testing shader model 1-3 targets you want a d3d9 device,
for shader model 4 a d3d10 device, and for shader model 5 a d3d11
device. I think it's fine to start with SM1-3 on a d3d9 device, but it
should be made easy to add e.g. SM4 on d3d10.
