re-review test language which should match spec language

@TallTed as this PR is part of a chain with other tests in it perhaps we should merge this as is and fix once that issue has been addressed and the group can agree on consensus on spec text? The big issue I'm running into here is that there are 4 more PRs branched from this branch which build on the features uses in this PR, and some of those PRs contain tests and features that would improve main and make the suite extensible. So it seems like we need to monitor and update test titles more.

@TallTed thank you for the issue, I am making a note to review the spec text on Friday if I miss the changes. How to keep these suites in touch with the existing specs is known problem we're working on.
