NUnit and time measurements

It’s common, that some part of your NUnit tests are tests, that should log their execution time. One of the ways of providing such a behavior is to provide custom SetUp and TearDown methods whether in your fixture or in a base test fixture. I find it disturbing, as a simple SetUp can be bloated with plenty of concerns.
Another way of providing it is using not a well-known interface of ITestAction. It allows to execute code before and after test in an AOP way. Of course one can argue that a simple method accepting action which execution will be measured is a better option, but I prefer coding in a declarative way and using a simple attribute visible in the signature of your method seems much more suited for this kind of behavior.
Take a look at the gist below and use it in you tests!
