Update the CodebaseHQ tests to use the new hosting service test helpers.
Review Request #9777 — Created March 14, 2018 and submitted — Latest diff uploaded
This updates the CodebaseHQ test suite to use the new helpers for
hosting service unit tests, which provide better, more consistent checks
with simpler code. The results of all HTTP requests are checked,
ensuring we're calling what we expect and that behavior doesn't change
in the future.
Unit tests pass.
