***CppQuickCheck***

## ABOUT

CppQuickCheck is a library for automated testing of C++ code. You provide a

specification how your code is supposed to behave through *properties* and

CppQuickCheck will generate a large number of random test cases that attempt to

prove or disprove the properties. The specifications are written in pure C++

using the functionality of the CppQuickCheck library.

## DOCUMENTATION

You can find examples in 'examples/src'.

## BACKGROUND

CppQuickCheck is inspired and based on the

[QuickCheck](http://code.haskell.org/QuickCheck/) library for

Haskell. CppQuickCheck differs in some aspects of the implementation and

interface (as well as being written in C++ instead of Haskell), but tries to

maintain similar functionality to the QuickCheck library.

A similar library for C++ exists called

[QuickCheck++](http://software.legiasoft.com/quickcheck/). QuickCheck++ does

not support several important things that the Haskell QuickCheck supports

including:

  * *Generator combinators* - In QuickCheck++ custom generators for user

    defined types are written by hand, with no provided random number

    generation facility. One example of a way that Haskell's QuickCheck (and

    CppQuickCheck) improve on this is the function `oneof` whick takes a list

    of generators and creates a new generator that when called, selects a

    random generator from the list and uses that to generate the input. In

    QuickCheck++ this has to be written by hand using some external random

    number generating library.

  * *Shrinking the input for failed test cases* - When a randomly generated

    test case fails, Haskell's QuickCheck (and CppQuickCheck, but not

    QuickCheck++) will try to shrink the input to provide a minimal failing

    case. This makes debugging the failure easier because instead of working

    with a potentially large input case, much of the input can be removed to

    reveal the structure of the failure.

For these reasons, CppQuickCheck tries to maintain all the functionality of the

Haskell QuickCheck, and so taking a different implementation approach than

QuickCheck++.

## UNIT TESTS

Unit tests exists in the directory 'test'.

```

$ cmake .

$ make check

```

To get a more detailed output, rerun it with

```

$ ./all-catch-tests

```

## CONTRIBUTING

Please direct your pull requests to https://github.com/philipp-classen/CppQuickCheck,

which is the repository where the active development takes place.

Currently, CppQuickCheck uses C++11 but not C++14. Travis will compile

the library and run the tests with GCC 4.9 and Clang 3.8.
