module Test.HUnit.ShouldBe

-- | <tt>actual `shouldBe` expected</tt> asserts that <tt>actual</tt> is
--   equal to <tt>expected</tt> (this is just an alias for <a>@?=</a>).
shouldBe :: (Show a, Eq a) => a -> a -> Assertion

-- | <tt>v `shouldSatisfy` p</tt> asserts that <tt>p v</tt> is
--   <tt>True</tt>.
shouldSatisfy :: Show a => a -> (a -> Bool) -> Assertion

-- | <tt>action `shouldReturn` expected</tt> asserts that <tt>action</tt>
--   returns <tt>expected</tt>.
shouldReturn :: (Show a, Eq a) => IO a -> a -> Assertion

-- | <tt>action `shouldThrow` selector</tt> asserts that <tt>action</tt>
--   throws an exception. The precise nature of that exception is described
--   with a <a>Selector</a>.
shouldThrow :: Exception e => IO a -> Selector e -> Assertion

-- | A <tt>Selector</tt> is a predicate; it can simultaneously constrain
--   the type and value of an exception.
type Selector a = a -> Bool
anyException :: Selector SomeException
anyErrorCall :: Selector ErrorCall
anyIOException :: Selector IOException
anyArithException :: Selector ArithException
errorCall :: String -> Selector ErrorCall


-- | Experimental combinators, that may become part of the main
--   distribution, if they turn out to be useful for a wider audience.
