I think you should import this with a prefix and use it when
accessing output to make the test more readable.

Done.

+import 'dart:isolate';
+import '../../../pkg/unittest/unittest.dart';
+
+expectResponse() {
+  port.receive(expectAsync2((msg, r) {
+    expect('success', msg);

Maybe also have:
expect('success', <prefix>.output);

[justinfagnani, 2012/10/17 18:11:56]

It should be a different instance of the output variable, since this code runs
in the main isolate. Adding an expect that it has a different value, like your
next comments, to be sure.

+    port.close();

+void main() {
+  test("package in spawnFunction()", () {
+    expectResponse();

<prefix>.output = 'junk';

[justinfagnani, 2012/10/17 18:11:56]

Done.

+    sendPort.send("sendPort", port.toSendPort());

Done.
