I think Daniel is actually using Cabal HEAD which has the detailed-0.9
test type enabled. If one tries that test type with the release
Cabal-1.10 then one does indeed get a warning at configure time.

The behaviour with Cabal-1.10 is:

$ cabal configure --enable-tests
Resolving dependencies...
Configuring zlib-
Warning: 'detailed-0.9' is not a supported test suite version.
The known test suite types are: exitcode-stdio-1.0

$ cabal test
Running 1 test suites...
0 of 1 test suites (0 of 1 test cases) passed.

Daniel can you check if you are indeed using Cabal HEAD or not?
