I recently discovered the constraint model in NUnit. It’s been there for years, hiding in plain sight! What is it? Is it worth using? Let’s check it out.

Unit testing a WinForms app is an uphill battle in the best of times, before you add in classes like MessageBox. Let’s make the best of it.

If you find yourself supporting a WinForms application, you’re likely to notice the tests… or lack thereof. Just because we may not have been so focused on automated tests and continuous integration when WinForms was younger, that doesn’t mean we can’t introduce them now. Better late than never!

When you’re writing tests, you generally don’t want to write to the database, email customers, and hit third-party API’s. That’s why we need to know how to mock dependencies!

Porting .NET Framework code to .NET Standard has been a learning experience, with some challenges too. This time I had a .NET Standard library that expected an application config file, but loading one from an NUnit test suite proved to be more difficult than it sounded at first.

Ever had an EUnit test fixture fail with meck reporting it was “already_started”? Well I did, and here’s why…

Are you a Mac user and .NET fan? Did you know there’s a native VS app now? Writing tests is important, so I decided to try out NUnit in @vs4mac.
