45 /// A test result is a simple pair of (type, reason).  The type indicates the
46 /// semantics of the results, and the optional reason provides an extra
47 /// description of the result type.
48 ///
49 /// In general, a 'passed' result will not have a reason attached, because a
50 /// successful test case does not deserve any kind of explanation.  We used to
51 /// special-case this with a very complex class hierarchy, but it proved to
52 /// result in an extremely-complex to maintain code base that provided no
53 /// benefits.  As a result, we allow any test type to carry a reason.
