It works well, but I like the assertion syntax found in NUnit better, so I decided to implement my own extension to the SysTest framework.
Now you can write assertions like this:
assert.that(actual, is.equalTo(expected)); assert.that(0.3333, is.equalTo(0.33).within(2).decimals()); assert.that(actual != null);
I think the syntax makes the test more readable.
You can download the framework at Codeplex
