Testing trouble?

Could someone please help me figure out this, my first test ever?

When I try to run a test based on the one in Agile, p. 145, I get this
error:

#BEGIN ERROR
Loaded suite test/unit/member_test
Started
F
Finished in 0.469879 seconds.

  1. Failure:
    test_create(MemberTest) [test/unit/member_test.rb:8]:

    expected to be kind_of?
    but was
    .

1 tests, 1 assertions, 1 failures, 0 errors
#END ERROR

What does that mean? Any clue to what I’m doing wrong?

(Also, despite entering the proper preferences at the list site, I
don’t receive messages I post to this list. Does anyone know what
that’s about?)

Best,

Jacob
