Test.Hspec

A lightweight implementation of a subset of Hspec's API.

Types

data SpecM a

Instances

Monad SpecM

Methods

(>>=) :: SpecM a -> (a -> SpecM b) -> SpecM b

(>>) :: SpecM a -> SpecM b -> SpecM b

return :: a -> SpecM a

fail :: String -> SpecM a

Functor SpecM

Methods

fmap :: (a -> b) -> SpecM a -> SpecM b

(<$) :: a -> SpecM b -> SpecM a

Applicative SpecM

Methods

pure :: a -> SpecM a

(<*>) :: SpecM (a -> b) -> SpecM a -> SpecM b

liftA2 :: (a -> b -> c) -> SpecM a -> SpecM b -> SpecM c

(*>) :: SpecM a -> SpecM b -> SpecM b

(<*) :: SpecM a -> SpecM b -> SpecM a

type Spec = SpecM ()

Defining a spec

describe :: String -> Spec -> Spec

context :: String -> Spec -> Spec

it :: String -> Expectation -> Spec

Setting expectations

type Expectation = IO ()

expect :: String -> Bool -> Expectation

shouldBe :: (Show a, Eq a) => a -> a -> Expectation infix 1

shouldReturn :: (Show a, Eq a) => IO a -> a -> Expectation infix 1

Running a spec

hspec :: Spec -> IO ()
