I'd recommend having a top level group and put this one test in it.

main() {
  group('Generate docs for', () {
    test('one simple file', () {
      ...
    });
  });
}

Disagree. Groups are only useful if you have multiple. Having one test in one
group  is unnecessary.

* Disabling tests in status files requires groups.

I stand corrected.

+  A() {
+    _someNumber = 12;
+  }
+  
+  void doThis(int a) {
+    print(a);
+  }

You can change this test to not use expectAsync because the future completes
with out errors. See tests/html/websql_test.dart or tests/html/xhr_test.dart for
examples of this system. 

+      var testLibraryUri = currentDirectory.resolve('test.dart');
+      var library = generateLibrary(mirrorSystem.libraries[testLibraryUri]);
+      expect(library is Library, isTrue);
+      
+      var classes = library.classes.values;
+      expect(classes.every((e) => e is Class), isTrue);
+      
+      var classMethods = [];
+      classes.forEach((e) => classMethods.addAll(e.methods.values));
+      expect(classMethods.every((e) => e is Method), isTrue);
+      
+      var methodParameters = [];
+      classMethods.forEach((e) => methodParameters.addAll(e.parameters.values));
+      expect(methodParameters.every((e) => e is Parameter), isTrue);
+      
+      var functions = library.functions.values;
+      expect(functions.every((e) => e is Method), isTrue);
+      
+      var functionParameters = [];
+      functions.forEach((e) => functionParameters.addAll(e.parameters.values));
+      expect(functionParameters.every((e) => e is Parameter), isTrue);
+
+      var variables = library.variables.values;
+      expect(variables.every((e) => e is Variable), isTrue);
+      
+      file.deleteSync();
+    }));
+  });
