Snap.Snaplet.Test
Contents
Description
The Snap.Snaplet.Test module contains primitives and combinators for testing Snaplets.
- evalHandler :: MonadIO m => Maybe String -> RequestBuilder m () -> Handler b b a -> SnapletInit b b -> m (Either Text a)
- runHandler :: MonadIO m => Maybe String -> RequestBuilder m () -> Handler b b a -> SnapletInit b b -> m (Either Text Response)
- withTemporaryFile :: FilePath -> IO () -> IO ()
Testing handlers
evalHandler :: MonadIO m => Maybe String -> RequestBuilder m () -> Handler b b a -> SnapletInit b b -> m (Either Text a)Source
Given a Snaplet Handler, a SnapletInit specifying the initial state,
and a RequestBuilder defining a test request, runs the handler,
returning the monadic value it produces.
Throws an exception if the Snap handler early-terminates with finishWith
or mzero.
Note that the output of this function is slightly different from
'evalHandler defined in Snap.Test, because due to the fact running
the initializer inside SnapletInit can throw an exception.
runHandler :: MonadIO m => Maybe String -> RequestBuilder m () -> Handler b b a -> SnapletInit b b -> m (Either Text Response)Source
Given a Snaplet Handler and a RequestBuilder defining
a test request, runs the Handler, producing an HTTP Response.
Note that the output of this function is slightly different from
runHandler defined in Snap.Test, because due to the fact running
the initializer inside SnapletInit can throw an exception.
withTemporaryFile :: FilePath -> IO () -> IO ()Source
Remove the given file before running an IO computation. Obviously it
can be used with Assertion.
