I need to run some code before any test is executed and also some code after all tests are done. I thought there must be some attributes or marker interface to indicate the global initialization and termination code but couldn't find them.

Alternatively, if I can invoke xUnit programmatically, I can also achieve what I want to do by the following code:

... Main(string[] args) {
  try {
    MyGlobalSetup();
    RunAllTests();  // What goes into this method?
  }
  finally {
    MyGlobalTeardown();
  }
}

Can anyone provide me some hint about how to declaratively or programmally run some global setup/teardown code?

Thanks
