One of the things I will look at in "Keeping Tests Dry" at next week's erubycon is various ways people test ActiveRecord validations.
Here's one bad idea:
def test_contact_requires_name
c = Contact.new
err = assert_raise(ActiveRecord::RecordInvalid) {
c.save!
}
assert_equal "Validation failed: Name can't be blank",
err.message
endWhat's wrong with this example? (More to follow...)
