No, you're confusing sender and receiver.  The receiver is indeed nil, the
sender is shown as nil because it's been nilled out when the context

Something else to try:

Test class>>run
  ^ thisContext copy

evaluating "Test run sender" should give you the response you were looking
for (of course, Test run sender should be == thisContext, so I'm not sure
what the original point was).
