Expect: First Class Assertions

 (require expect) package: expect

This library provides expectations, composable first-class representations of assertions that should be true of some value. This library integrates with RackUnit to provide checks in terms of expectations, making it simpler to create custom checks with high-quality error messages.

Source code for this library is avaible on Github
