Learn & Hack

Franklin Chen will give a talk on property-based testing (more info below), and then we'll spend some time hacking on the pgh scala website.

Beyond xUnit: property-based testing - Franklin Chen

Test-Driven Development has become deservedly popular in the past
decade, with easy-to-use xUnit unit testing frameworks leading the way
toward encouraging developers to write tests. But xUnit has
limitations: how does one know one has written enough test cases for a
desired behavior? And what if the behavior is conditional on other
behavior? Property-based testing, first popularized for Haskell with
the QuickCheck library, but available now for other languages as well,
offers a powerful addition to one's testing toolkit.

I will discuss the concepts of property-based testing and illustrate
them concretely using ScalaCheck for Scala, and point toward similar
test frameworks in other languages.
