openSUSE:Factory The next openSUSE distribution Any user who wishes to have the newest packages that include, but are not limited to, the Linux kernel, SAMBA, git, desktops, office applications and many other packages, will want Tumbleweed. Tumbleweed appeals to Power Users, Software Developers and openSUSE Contributors. If you require the latest software stacks and Integrated Development Environment or need a stable platform closest to bleeding edge Linux, Tumbleweed is the best choice for you. Staging dashboard is located at: https://build.opensuse.org/staging_workflows/openSUSE:Factory List of known devel projects: https://build.opensuse.org/package/view_file/openSUSE:Factory:Staging/dashboard/devel_projects Have a look at http://en.opensuse.org/Portal:Factory for more details. https://download.opensuse.org/tumbleweed/repo/oss/ ghc-QuickCheck Automatic testing of Haskell programs QuickCheck is a library for random testing of program properties. The programmer provides a specification of the program, in the form of properties which functions should satisfy, and QuickCheck then tests that the properties hold in a large number of randomly generated cases. Specifications are expressed in Haskell, using combinators provided by QuickCheck. QuickCheck provides combinators to define properties, observe the distribution of test data, and define test data generators. Most of QuickCheck's functionality is exported by the main "Test.QuickCheck" module. The main exception is the monadic property testing library in "Test.QuickCheck.Monadic". If you are new to QuickCheck, you can try looking at the following resources: * The <http://www.cse.chalmers.se/~rjmh/QuickCheck/manual.html official QuickCheck manual>. It's a bit out-of-date in some details and doesn't cover newer QuickCheck features, but is still full of good advice. * <https://begriffs.com/posts/2017-01-14-design-use-quickcheck.html>, a detailed tutorial written by a user of QuickCheck. The <https://hackage.haskell.org/package/quickcheck-instances quickcheck-instances> companion package provides instances for types in Haskell Platform packages at the cost of additional dependencies.
