Hi Cabal,

Is there documentation for the new test-suite functionality? I tried adding the following stanza to my package description:

test-suite basic    default-language: Haskell2010    type: exitcode-stdio-1.0    main-is: Basic.hs    hs-source-dirs: tests

Running 'cabal test' only yields :

Running 0 test suites... 0 of 0 test suites (0 of 0 test cases) passed.

Am I doing something wrong? It would be nice if I got an error message. It doesn't seem to matter at all what I fill in to the stanza for the main-is and hs-source-dirs fields.

Thanks, Antoine

Are you configuring/building the package with the commands 'cabal configure --enable-tests' and 'cabal build' before trying to run tests?  I suspect the problem you are encountering is that the default option for 'configure' is '--disable-tests'.  I apologize for the confusion; this is documented in the Cabal User's Guide, but obviously the documentation I wrote needs improvement :)

Yep, that was it. Is there a reason the 'test' command doesn't work by default? It seems odd that typing 'cabal test' isn't enough of an indication of what I wanted to do. There are probably backwards compatibility concerns I don't know about, though. Thanks for the help and for developing the test-suite infrastructure. Antoine

This case also indicates to me that we need to add a gentle reminder about 'cabal configure --enable-tests' whenever 'cabal test' is invoked, but no test suites are found.
