My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=main 2026-05-25T22:11:13+00:00 2026-05-25T22:11:13+00:00 Craig Jennings c@cjennings.net 2026-05-25T22:11:13+00:00 urn:sha1:37917d5b34155c072752697e0309011d3f17a56e mu4e-org-contacts-integration.el had no tests. I added ten characterization tests for the completion glue. The capf only fires inside a header field of a compose buffer, so I check it both ways (wrong mode, wrong field) plus the bounds and table it returns when contacts exist and the empty-contacts case. TAB dispatches three ways depending on context, so each branch gets a test: completion-at-point in a header, org-cycle in the org-msg body, indent elsewhere. Comma completion and the direct-insert path round it out. The header predicate, the mode actions, and cj/get-all-contact-emails are stubbed, so the run stays headless with no mu4e or org-contacts dependency.
