Hedgehog is a property-based testing system, in the spirit of QuickCheck. Hedgehog uses integrated shrinking, so shrinks obey the invariants of generated values by construction.

To get started quickly, see the examples: https://github.com/hedgehogqa/haskell-hedgehog/tree/master/hedgehog-example

With the function Test.Tasty.ExpectedFailure.expectFail in the provided module Test.Tasty.ExpectedFailure, you can mark that you expect test cases to fail, and not to pass. This can be used for test-driven development.

This package provides SmallCheck support for the Tasty Haskell test framework.

This package adds the ability to run tests by filtering the test tree based on the result of a previous test run. You can use this to run only those tests that failed in the last run, or to only run the tests that have been added since previous test run.

HUnit is a unit testing framework for Haskell, inspired by the JUnit tool for Java.

This package provides an IO library for testing interactive command line programs. Proctest aims to simplify interacting with and testing terminal programs, providing convenience functions for starting programs and reading their output. All blocking operations support timeouts so that misbehaving programs cannot block your test pipeline. Find more examples and contribute at https://github.com/nh2/proctest.

This package provides QuickCheck support for the Tasty Haskell test framework.

Nanospec is a lightweight implementation of a subset of Hspec's API with minimal dependencies.

Feat (Functional Enumeration of Algebraic Types) provides enumerations as functions from natural numbers to values (similar to toEnum but for any algebraic data type). This can be used for SmallCheck-style systematic testing, QuickCheck-style random testing, and hybrids of the two.

Some carefully crafted libraries make promises to their users beyond functionality and performance.

Examples are: Fusion libraries promise intermediate data structures to be eliminated. Generic programming libraries promise that the generic implementation is identical to the hand-written one. Some libraries may promise allocation-free or branch-free code.

Conventionally, the modus operandi in all these cases is that the library author manually inspects the (intermediate or final) code produced by the compiler. This is not only tedious, but makes it very likely that some change, either in the library itself or the surrounding eco-system, breaks the library's promised without anyone noticing.

This package provides a disciplined way of specifying such properties, and have them checked by the compiler. This way, this checking can be part of the regular development cycle and regressions caught early.

See the documentation in "Test.Inspection" or the project webpage for more examples and more information.

This package provides generator and shrink functions for testing Unicode-related software.

This package gives users the ability to define tasty tests from Lua.

This package lets programmers use SmallCheck properties in Haskell's test-framework. New projects should use ghc-tasty-smallcheck instead.

This library provides a stable version of Hspec which is used to test the in-development version of Hspec.

This Haskell library provides convenient assertions with pretty-printed failure messages for QuickCheck properties, that are similar to those of HUnit.

A tasty ingredient to output test results in XML, using the Ant schema. This XML can be consumed by the Jenkins continuous integration framework.

This library exposes internal types and functions that can be used to extend Hspec's functionality.

This package provides the means for integrating the hedgehog testing library with the tasty testing framework.

This Haskell package contains generic tests for cryptographic ciphers, and is used by the test runners of various Haskell implementations of cryptographic ciphers.

This library is a minimal variant of `quickcheck-classes` that only provides laws for typeclasses from `base`. The main purpose of splitting this out is so that `primitive` can depend on `quickcheck-classes-base` in its test suite, avoiding the circular dependency that arises if `quickcheck-classes` is used instead. This library provides QuickCheck properties to ensure that typeclass instances adhere to the set of laws that they are supposed to. There are other libraries that do similar things, such as `genvalidity-hspec` and `checkers`. This library differs from other solutions by not introducing any new typeclasses that the user needs to learn. Note: on GHC < 8.5, this library uses the higher-kinded typeclasses (Data.Functor.Classes.Show1, Data.Functor.Classes.Eq1, Data.Functor.Classes.Ord1, etc.), but on GHC >= 8.5, it uses `-XQuantifiedConstraints` to express these constraints more cleanly.

This package provides HUnit support for the test-framework package.

This library provides catchy combinators for HUnit, see the README.

This library contains two functions: defaultMainGenerator and testGroupGenerator.

defaultMainGenerator will extract all functions beginning with case_, prop_, or test_ in the module and put them in a testGroup.

testGroupGenerator is like defaultMainGenerator but without defaultMain. It is useful if you need a function for the testgroup (e.g. if you want to be able to call the testgroup from another module).
