QuickCheck-like testing framework for Python
Project description
pyqcy [pyksi:] is an automated testing framework for Python inspired by the wonderful QuickCheck library for Haskell.
What’s the idea?
Instead of writing fully-fledged test cases, with pyqcy you simply define logical properties that your code is expected to satisfy. Based on that, pyqcy will automatically generate test cases for you - hundreds of them, in fact!
How does it look like?
For starters, try this:
from pyqcy import qc, int_, main @qc def addition_actually_works( x=int_(min=0), y=int_(min=0) ): the_sum = x + y assert the_sum >= x and the_sum >= y if __name__ == '__main__': main()
$ pip install pyqcy $ python test.py addition_actually_works: passed 100 tests.
pyqcy generated 100 test cases and checked whether they all pass. For a few lines of code, that’s rather nice, isn’t it? :)
Of course, you are not limited to integers - there is built-in support for all standard types, including lists and dictionaries. Custom classes can be used as well: just specify how to generate an @arbitrary object of your class, and you’re set.
Hey, I like it!
