The repo had no tests at all, which the v0.4.0 rewrite made
uncomfortable: this client speaks terdut-server's REST API directly, and
a wrong path or method is invisible until somebody runs the binary
against a live server. That is exactly how it broke when the server split
alerts from incidents.
The Elm architecture makes most of this cheap to check without a
terminal. Update is (Model, Msg) -> (Model, Cmd), so keypresses can be
synthesised and the resulting model inspected; a nil command is a
readable assertion that the model decided to do nothing.
Three suites:
- client_test.go drives every incident endpoint against an httptest
stub that records method, path, query and body. Also covers the
filter query params, that a server error message survives into the
error the UI shows, that a 404 from the on-call endpoint is not an
error, and that omitted optional fields decode to zero rather than
failing.
- model_test.go covers the pure helpers: filter cycling, the snoozed
pseudo-status, duration formatting, row builders, and the column
width arithmetic that overflowed the terminal once already.
- update_test.go covers the rules worth protecting rather than
coverage for its own sake. Resolve prompts first and cancelling does
not act, since resolution is terminal server-side. A resolved
incident rejects all six workflow keys. Archiving refuses while an
incident is open. The note cursor walks notes only and wraps. Stats
returns to whichever view opened it. Modal states do not auto-refresh
underneath the user.
129 tests, running in about 40ms.
