NUnit 2.4 RC2 is out now, correcting a naming conflict with several mock object frameworks that was present in RC1. You can download it at NUnit.org. For a full list of the extensive new features in NUnit 2.4, check out the Release Notes.
NUnit has lots of tests of its own - unit tests that is. It even has some fairly high-level tests that don't fit well into the normal unit-testing paradigm. But, up to now, the only acceptance tests were manual - a list of things I do before uploading a new release. Since they are manual, they don't get run all that often and surprises happen.
In an earlier post, I presented some ideas about syntax for expressing assertions in tests. I was doing this as a part of the development of NUnitLite, with the idea of eventually putting some of the same concepts back into NUnit.
NUnit has finally gotten rid of it's Visual Studio Install projects in favor of WiX
Sometimes you expect an exception to be thrown by a method. So, of course, you want a test for that. NUnit provides the ExpectedExceptionAttribute for that purpose. It has a bit of history...
I've been using the development of NUnitLite (coming soon!) as an excuse to try out alternatives to the standard NUnit syntax for Asserts.
In an earlier article I wrote about my concern with OpenDomain.org. They had acquired the nunit.net domain and were offering me the right to use it in exchange for a link. I felt uncomfortable about this, particularly after I learned about their dispute over the WordPress.com domain.
At OSCON, I spoke about NUnit for Cross-Platform development. Here are some screenshots from that talk, showing NUnit running under Mono 1.1.13 on Ubuntu Linux. (Click to enlarge)
People want what they want. If NUnit doesn't have a feature that they need, they ask for it. Of course, we can't implement all of them, so some people want to be able to create there own test runner using the NUnit assemblies.
A post on the TDD list asks about running NUnit tests using the Start button in Visual C# Express. In Visual Studio 2003 and 2005, you can set up a project's Debug properties so that an arbitrary external program is executed. By selecting NUnit as that program and providing the correct command-line options, you can cause your tests to be run.
