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.

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

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.

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

This package provides a stable API that can be used to extend Hspec's functionality.

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

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

This package provides contributed Hspec extensions.

Property based testing libraries such as QuickCheck tend to include type modifiers. Most of them are used to quantify over subsets of a type. This library is intended to supply these modifiers to be used by testing libraries, in an effort to make properties more portable between testing frameworks.

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 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.

The usual Arbitrary instance for Text (in <https://hackage.haskell.org/package/quickcheck-instances quickcheck-instances>) only has single-byte instances and so isn't an ideal representation of a valid UTF-8 character. This package has generators for one-, two- and three-byte UTF-8 characters (all that are currently in use).

Parts of doctest exposed as library. For use with the doctest-extract utility.

Tasty-th automatically generates tasty TestTrees from functions of the current module, using TemplateHaskell. This is a fork the original test-framework-th package, modified to work with tasty instead of test-framework.

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.

Integrate @inspection-testing@ into @tasty@ test suites.

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

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

This package provides an orphan instance that allows you to use HUnit assertions as QuickCheck properties.

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

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

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 a fancy test runner and support for golden testing. A golden test is an IO action that writes its result to a file. To pass the test, this output file should be identical to the corresponding ``golden'' file, which contains the correct result for the test. The test runner allows filtering tests using regexes, and to interactively inspect the result of golden tests.
