+;;;; ** Fixtures
+
+;;;; When running tests we often need to setup some kind of context
+;;;; (create dummy db connections, simulate an http request,
+;;;; etc.). Fixtures provide a way to conviently hide this context
+;;;; into a macro and allow the test to focus on testing.
+
+;;;; NB: A FiveAM fixture is nothing more than a macro. Since the term
+;;;; 'fixture' is so common in testing frameworks we've provided a
+;;;; wrapper around defmacro for this purpose.
