A type class for examples.

Combine a list of specs into a larger spec.

An alias for describe.

Create a spec item.

A spec item consists of:

• a textual description of a desired behavior
• an example for that behavior

 describe "absolute" $ do
   it "returns a positive number when given a negative number" $
     absolute (-1) == 1

Specifies a pending example.

If you want to textually specify a behavior but do not have an example yet, use this:

 describe "fancyFormatter" $ do
   it "can format text in a way that everyone likes" $
     pending

Run given spec and write a report to stdout. Exit with exitFailure if at least one spec item fails.

Summary of a test run.

Convert a Spec to a forest of SpecTrees.

Create a Spec from a forest of SpecTrees.
