pretty package:HTF

Pretty-print a single value.

This module defines the Pretty type class. The assert functions from HUnitWrapper use the pretty-printing functionality provided by this type class so as to provide nicely formatted error messages. Additionally, this module re-exports the standard Haskell pretty-printing module PrettyPrint

class Pretty a

HTF Test.Framework.Pretty

A type class for pretty-printable things. Minimal complete definition: pretty.

prettyList :: Pretty a => [a] -> Doc

HTF Test.Framework.Pretty

Pretty-print a list of things.

module Test.Framework.PrettyHaskell

HTF

Internal module for pretty-printing showable Haskell values.

assertEqualPretty :: (Eq a, Pretty a, HasCallStack) => a -> a -> IO ()

HTF Test.Framework.HUnitWrapper

Fail if the two values of type a are not equal. Use if a is an instance of Pretty.

assertEqualPrettyVerbose :: (Eq a, Pretty a, HasCallStack) => String -> a -> a -> IO ()

HTF Test.Framework.HUnitWrapper

Fail if the two values of type a are not equal, supplying an additional message. Use if a is an instance of Pretty.

assertNotEqualPretty :: (Eq a, Pretty a, HasCallStack) => a -> a -> IO ()

HTF Test.Framework.HUnitWrapper

Fail if the two values of type a are equal. Use if a is an instance of Pretty.

assertNotEqualPrettyVerbose :: (Eq a, Pretty a, HasCallStack) => String -> a -> a -> IO ()

HTF Test.Framework.HUnitWrapper

Fail if the two values of type a are equal, supplying an additional message. Use if a is an instance of Pretty.

gassertEqualPretty :: (Eq a, Pretty a, AssertM m, HasCallStack) => a -> a -> m ()

HTF Test.Framework.HUnitWrapper

Fail in some AssertM monad if the two values of type a are not equal. Use if a is an instance of Pretty.

gassertEqualPrettyVerbose :: (Eq a, Pretty a, AssertM m, HasCallStack) => String -> a -> a -> m ()

HTF Test.Framework.HUnitWrapper

Fail in some AssertM monad if the two values of type a are not equal, supplying an additional message. Use if a is an instance of Pretty.

gassertNotEqualPretty :: (Eq a, Pretty a, AssertM m, HasCallStack) => a -> a -> m ()

HTF Test.Framework.HUnitWrapper

Fail in some AssertM monad if the two values of type a are equal. Use if a is an instance of Pretty.

gassertNotEqualPrettyVerbose :: (Eq a, Pretty a, AssertM m, HasCallStack) => String -> a -> a -> m ()

HTF Test.Framework.HUnitWrapper

Fail in some AssertM monad if the two values of type a are equal, supplying an additional message. Use if a is an instance of Pretty.

showPretty :: Pretty a => a -> String

HTF Test.Framework.Pretty

Pretty-print a single value as a String.
