hspec version 0.4.3, Behavior Driven Development for Haskell, is now available!
Improvements include red/yellow/green color output and writing output as the tests are running. Also, you can import Test.Hspec.Monadic rather than Test.Hspec if you want to use a WriterMonad based api. http://hackage.haskell.org/package/hspec https://github.com/trystan/hspec As always, any advice, comments, or questions are welcome, Trystan Spangler For those who would like to see an example, using the new alternate monadic api, running this program: > import Test.Hspec.Monadic > import Test.Hspec.HUnit > import Test.Hspec.QuickCheck (property) > import Test.HUnit (assertBool, assertEqual) > > main = hspec specs > > specs = describe "hspec 0.4.3" $ do > it "still allows a Bool expression to act as an example" > (replicate 5 1 == [1,1,1,1,1]) > > it "still allows HUnit assertions to act as examples" > (assertBool "lame example" True) > > it "still allows QuickCheck properties to act as examples" > (property $ \ i -> (i::Int) == i + 1 - 1) > > it "still shows a list of failed examples" > (undefined :: Bool) -- expected to fail > > it "still collects better data from failed HUnit examples" > (assertEqual "this should fail" 1 2) -- expected to fail > > it "still collects better data from failed QuickCheck examples" > (property $ \ i -> (i::Int) * 2 - 2 /= i) -- expected to fail > > it "now allows a monadic api" > (pending "I'm still not sure how to test this but this example is good > evidence....") > > it "now outputs in color when writing to stdout" > (pending "I'm still not sure how to test this but trust me it works....") should send this to stdout in glorious red, yellow, and green: hspec 0.4.3 - still allows a Bool expression to act as an example - still allows HUnit assertions to act as examples - still allows QuickCheck properties to act as examples x still shows a list of failed examples FAILED [1] x still collects better data from failed HUnit examples FAILED [2] x still collects better data from failed QuickCheck examples FAILED [3] - now allows a monadic api # I'm still not sure how to test this but this example is good evidence.... - now outputs in color when writing to stdout # I'm still not sure how to test this but trust me it works.... 1) hspec 0.4.3 still shows a list of failed examples FAILED Prelude.undefined 2) hspec 0.4.3 still collects better data from failed HUnit examples FAILED this should fail expected: 1 but got: 2 3) hspec 0.4.3 still collects better data from failed QuickCheck examples FAILED *** Failed!
