Code in comments.

Done.

+  String message = '';
+  tls.onConnect = () {
+    foo1();
+    var get_list =

get_list -> get_bytes?

[Bill Hesse, 2012/11/11 22:34:34]

request_bytes is even better.

Maybe extend the test to performing this several times with a different constant
than 20 for each iteration.

[Bill Hesse, 2012/11/11 22:34:34]

We will be modifying it to use a local server, and can do it then.

+    foo2();
+    tls.writeList(get_list, 20, get_list.length - 20);
+  };
+  tls.onData = () {
+    foo3();
+    var buffer = new List(2000);
+    int len = tls.readList(buffer, 0, 2000);
+    var received = new String.fromCharCodes(buffer.getRange(0, len));
+    message = '$message$received';
+  };
+  tls.onClosed = () {
+    print(message);
+    Expect.isTrue(message.contains('</script></body></html>'));
+    tls.close();
+  };
+}
+
+void foo1() {}

What is the purpose of these fooX functions?

[Bill Hesse, 2012/11/11 22:34:34]

Removed.
