Test.Tasty.Hedgehog
Description
This package lets you test Hedgehog properties with tasty.
Typical usage would look like this:
testGroup "tasty-hedgehog tests" [ testPropertyNamed "reverse involutive" "prop_reverse_involutive" prop_reverse_involutive , testPropertyNamed "sort idempotent" "prop_sort_idempotent" prop_sort_idempotent ]
Synopsis
- testProperty :: TestName -> Property -> TestTree
- testPropertyNamed :: TestName -> PropertyName -> Property -> TestTree
- fromGroup :: Group -> TestTree
- newtype HedgehogReplay = HedgehogReplay (Maybe (Size, Seed))
- newtype HedgehogShowReplay = HedgehogShowReplay Bool
- newtype HedgehogTestLimit = HedgehogTestLimit (Maybe TestLimit)
- newtype HedgehogDiscardLimit = HedgehogDiscardLimit (Maybe DiscardLimit)
- newtype HedgehogShrinkLimit = HedgehogShrinkLimit (Maybe ShrinkLimit)
- newtype HedgehogShrinkRetries = HedgehogShrinkRetries (Maybe ShrinkRetries)
Documentation
testPropertyNamed :: TestName -> PropertyName -> Property -> TestTree Source #
testPropertyNamed testName propertyName property creates a
TestTree from property using testName as the displayed
description for the property. The propertyName is used by Hedgehog
when a failure occurs to provide instructions for how to re-run
the property and should normally be set to a string representation
of the property argument.
testPropertyNamed "reverse is involutive" "prop_reverse_involutive" prop_reverse_involutive
Since: 1.2.0.0
