Can't run the tests

[erikd]

Having an incredible amount of difficulty simply running the tests.

In PR #23 I mentioned this and you said you run the tests in GHCi. I tried, but this is rather non-trivial because I'm running in a cabal sandbox:

$ cabal exec -- ghci -itest test/Test/Hspec/ExpectationsSpec.hs 
GHCi, version 7.10.3: http://www.haskell.org/ghc/  :? for help

test/Test/Hspec/ExpectationsSpec.hs:11:18:
    Could not find module ‘Test.Hspec’
    Use -v to see a list of the files searched for.
Failed, modules loaded: none.

So I installed hspec and tried again, only to get a number of errors like:

test/Test/Hspec/ExpectationsSpec.hs:61:7: Warning:
    No instance for (Data.String.IsString (t0 a0))
      arising from the literal ‘""’
    The type variables ‘t0’, ‘a0’ are ambiguous
    Note: there is a potential instance available:
      instance Data.String.IsString [Char] -- Defined in ‘Data.String’
    In the first argument of ‘shouldSatisfy’, namely ‘""’
    In a stmt of a 'do' block: "" `shouldSatisfy` null
    In the second argument of ‘($)’, namely
      ‘do { "" `shouldSatisfy` null }’

On top of that, the lack of any tests in the cabal file means that the travis script can't build and run the tests.

So I tried to add a testsuite section to the cabal file only to find that the there seems to be a circular dependency between hspec-expectations and hspec and hspec-discover that cabal doesn't seem to be able to resolve. The solution seems to be to test hspec-expectations with something other than hspec itself.

Would you accept a PR that adds a proper working testsuite section to the cabal file?

I think the issue is due to the AMP changes. null is too generic now. I guess we should fix that first.

We could try to use nanospec for testing, but I guess there is a reason why it's currently not like that...

I guess we should run with runhaskell on Travis

Its not AMP because I get very similar problems with ghc 7.8.

[sol]

Do you have OverloadedStrings in your global .ghci?

[erikd]

Yes, that may be it.
