pendingWith :: HasCallStack -> String -> Expectation

pendingWith is similar to pending, but it takes an additional string argument that can be used to specify the reason for why the spec item is pending.

pending :: HasCallStack -> Expectation

pending can be used to mark a spec item as pending.

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

sequential :: SpecWith a -> SpecWith a

sequential marks all spec items of the given spec to be evaluated sequentially.

parallel :: SpecWith a -> SpecWith a

parallel marks all spec items of the given spec to be safe for parallel evaluation.

xspecify :: (HasCallStack, Example a) => String -> a -> SpecWith (Arg a)

xspecify is an alias for xit.

xit :: (HasCallStack, Example a) => String -> a -> SpecWith (Arg a)

Changing it to xit marks the corresponding spec item as pending.

This can be used to temporarily disable a spec item.

specify :: (HasCallStack, Example a) => String -> a -> SpecWith (Arg a)

specify is an alias for it.

xcontext :: HasCallStack => String -> SpecWith a -> SpecWith a

xcontext is an alias for xdescribe.

xdescribe :: HasCallStack => String -> SpecWith a -> SpecWith a

Changing describe to xdescribe marks all spec items of the corresponding subtree as pending.

This can be used to temporarily disable spec items.

context :: HasCallStack => String -> SpecWith a -> SpecWith a

context is an alias for describe.

modifyParams :: (Params -> Params) -> SpecWith a -> SpecWith a

mapSpecItem_ :: (Item a -> Item a) -> SpecWith a -> SpecWith a

mapSpecItem :: (ActionWith a -> ActionWith b) -> (Item a -> Item b) -> SpecWith a -> SpecWith b

runIO :: IO r -> SpecM a r

Run an IO action while constructing the spec tree.

SpecM is a monad to construct a spec tree, without executing any spec items. runIO allows you to run IO actions during this construction phase. The IO action is always run when the spec tree is constructed (e.g. even when --dry-run is specified). If you do not need the result of the IO action to construct the spec tree, beforeAll may be more suitable for your use case.

fromSpecList :: [SpecTree a] -> SpecWith a

Create a Spec from a forest of SpecTrees.

runSpecM :: SpecWith a -> IO [SpecTree a]

Convert a Spec to a forest of SpecTrees.

type SpecTree a = Tree (ActionWith a) (Item a)

A tree is used to represent a spec internally. The tree is parametrize over the type of cleanup actions and the type of the actual spec items.

data Item a

Item is used to represent spec items internally. A spec item consists of:

• a textual description of a desired behavior
• an example for that behavior
• additional meta information

Everything that is an instance of the Example type class can be used as an example, including QuickCheck properties, Hspec expectations and HUnit assertions.

Constructors

Item

Fields

• itemRequirement :: String

  Textual description of behavior

• itemLocation :: Maybe Location

  Source location of the spec item

• itemIsParallelizable :: Maybe Bool

• itemExample :: Params -> (ActionWith a -> IO ()) -> ProgressCallback -> IO Result
