@hackage chell0.2.5

Chell is a simple and intuitive library for automated testing. It natively supports assertion-based testing, and can use companion libraries such as chell-quickcheck to support more complex testing strategies.

An example test suite, which verifies the behavior of artithmetic operators.

    $expect (equal (2 + 1) 3)

    $expect (equal (2 - 1) 1)
    $expect (equal (1 - 2) (-1))
