This module exports everything that you need to be able to create your own framework test provider. To create a provider you need to:

- Create an instance of the
`Testlike`

class - Create an instance of the
`TestResultlike`

class - Expose a function that lets people construct
`Test`

values using your new instances

- data Test
- = (Testlike i r t, Typeable t) => Test TestName t

class (Show i, Show r) => TestResultlike i r | r -> i where #

Something like the result of a test: works in concert with `Testlike`

.
The type parameters are the type that is used for progress reports and the
type of the final output of the test respectively.

testSucceeded :: r -> Bool #

class TestResultlike i r => Testlike i r t | t -> i r, r -> i where #

Something test-like in its behaviour. The type parameters are the type that is used for progress reports, the type of the final output of the test and the data type encapsulating the whole potential to do a test respectively.

runTest :: CompleteTestOptions -> t -> IO (i :~> r, IO ()) #

testTypeName :: t -> TestTypeName #

Testlike i r t => Testlike i r (MutuallyExcluded t) # | |

type TestTypeName = String #

The name of a type of test, such as Properties or "Test Cases". Tests of types of the same names will be grouped together in the test run summary.

Main test data type: builds up a list of tests to be run. Users should use the
utility functions in e.g. the test-framework-hunit and test-framework-quickcheck
packages to create instances of `Test`

, and then build them up into testsuites
by using `testGroup`

and lists.

For an example of how to use test-framework, please see http://github.com/batterseapower/test-framework/raw/master/example/Test/Framework/Example.lhs

(Testlike i r t, Typeable t) => Test TestName t | A single test of some particular type |

TestGroup TestName [Test] | Assemble a number of tests into a cohesive group |

PlusTestOptions TestOptions Test | Add some options to child tests |

BuildTestBracketed (IO (Test, IO ())) | Convenience for creating tests from an |

plusTestOptions :: TestOptions -> Test -> Test #

Add some options to child tests

buildTestBracketed :: IO (Test, IO ()) -> Test #

Convenience for creating tests from an `IO`

action, with a cleanup handler for when tests are finished

mutuallyExclusive :: Test -> Test #

Mark all tests in this portion of the tree as mutually exclusive, so only one runs at a time

bimapImproving :: (a -> c) -> (b -> d) -> (a :~> b) -> c :~> d #

improvingLast :: (a :~> b) -> b #

consumeImproving :: (a :~> b) -> [a :~> b] #

data ImprovingIO i f a #

Monad (ImprovingIO i f) # | |

Functor (ImprovingIO i f) # | |

Applicative (ImprovingIO i f) # | |

yieldImprovement :: i -> ImprovingIO i f () #

runImprovingIO :: ImprovingIO i f f -> IO (i :~> f, IO ()) #

tunnelImprovingIO :: ImprovingIO i f (ImprovingIO i f a -> IO a) #

liftIO :: IO a -> ImprovingIO i f a #

timeoutImprovingIO :: Int -> ImprovingIO i f a -> ImprovingIO i f (Maybe a) #

Given a number of microseconds and an improving IO action, run that improving IO action only
for at most the given period before giving up. See also `timeout`

.

maybeTimeoutImprovingIO :: Maybe Int -> ImprovingIO i f a -> ImprovingIO i f (Maybe a) #

As `timeoutImprovingIO`

, but don't bother applying a timeout to the action if `Nothing`

is given
as the number of microseconds to apply the time out for.
