This interface is really hard to read. Why is the status a string? Why not a
boolean or, if it can have more than two values, an enum?

I'd also make the status and description named parameters. Having three unnamed
strings in a row is really confusing.

I eliminated expectSingleTest. Fewer methods == better

     setUp(() {
       return new Future.value(0);
     });
     tearDown(() {
       return new Future.value(0);
     });
     test('foo1', () {});
   });
-  group('good setup/bad teardown', () {
+
+  expectSingleTest(
+      'good setup/bad teardown',
+      'error',
+      'Teardown failed: Caught Failed to complete tearDown',
+      () {
     setUp(() {
       return new Future.value(0);
     });
     tearDown(() {
       return new Future.error("Failed to complete tearDown");
     });
     test('foo2', () {});
   });
-  group('bad setup/good teardown', () {
+
+  expectSingleTest(
+      'bad setup/good teardown',
+      'error',
+      'Setup failed: Caught Failed to complete setUp',
+      () {
     setUp(() {
       return new Future.error("Failed to complete setUp");
     });
     tearDown(() {
       return new Future.value(0);
     });
     test('foo3', () {});
   });
-  group('bad setup/bad teardown', () {
+
+  expectSingleTest(
+      'bad setup/bad teardown',
+      'error',
+      'Setup failed: Caught Failed to complete setUp',
+      () {
     setUp(() {
       return new Future.error("Failed to complete setUp");
     });
     tearDown(() {
       return new Future.error("Failed to complete tearDown");
     });
     test('foo4', () {});
   });
-  // The next test is just to make sure we make steady progress
-  // through the tests.
-  test('post groups', () {});
-};

-final expected = buildStatusString(2, 0, 3,
