There are a couple of frameworks you should know about

We make extensive use of open-source

We rely on 3rd party open-source software while creating Nancy. All of these fall on the testing side of Nancy and since we try to use a TDD workflow, as much as possible, they are used a lot. In order to contribute to Nancy you're going to have to get acquainted with these since we are expecting (shocking right!) you to provide tests with your code. These tests will help us a ton with regression testing. Thanks for helping us out with it. Love you!

• MSpec; used for BDD style acceptance tests
• FakeItEasy; used for mocking in the unit tests
