For tests create an instance of the type to allow for test fixtureSetup and test fixture teardown (ala NUnit or .cstr, dispose of xUnit).

Hello,

As you see I made 2 changes; one is unvalid for a pull request since it's primairly a style change, the other is targeted at adding fixture setup functionality to the framework.
Please let me know what you think.

Greetings,
Peter
