[plt-scheme] tester-controller.ss & best way to do test cases

First, a bug report that I tried to file via the Help Desk Bug Report
Form, but seems to have hung with "Sending Bug Report" window
displayed and "Cancel" button disabled...

Somehow, a definition of "my-expand" has appeared in
"tester-controller.ss" outside of the "module" syntax:

    default-load-handler: expected only a `module' declaration for
    `tester-controller', but found an extra expression in:
    /usr/lib/plt/collects/tests/tester/private/tester-controller.ss

Second, what's the current official way for an add-on module developer
to encode and execute test cases?  Do we just follow the documentation
in "collects/tests/tester/doc.txt"?  Download SchemeUnit?  (The DrScheme
test boxes look student-oriented.)
