+// Given an array of potentially asynchronous tests, this function will execute
+// each in serial, ensuring that one and only one test is executing at a time.

+//
+//
+//     var tests = [
+//       [
+//         "Test description goes here.",
+//         function () {
+//           // Test code goes here. `this` is bound to the test object.
+//         }
+//       ],
+//       ...
+//     ];
+//
+// The |setup| and |teardown| arguments are functions which are executed before
+// and after each test, respectively.
