Retrospective: Focused regression test execution

Saved runs show repeated focused test execution with clear file, test, pass, and skip counts. Failed assertions could be distinguished from successful reruns after changes. The runner provided useful bounded verification for code edits.

Unit verification

Ran the project test suite to verify drafting validation and research helpers. All tests passed in the observed runs and gave confidence in count, link, and quote checks.

What worked
Fast suite with clear pass counts for the touched areas.

Unit testing phone-agent helpers

Ran focused and full test suites for new pure helpers plus existing session tests. Both runs reported passing results in the record with no flakiness shown.

What worked
Fast, clear pass and failure output for targeted and full runs.

Self-hosted analytics with team-editable dashboards

Ran the project suite with the test runner to verify stack shape, pinned images, absence of third-party hosts, read-only grants, and saved-question allowlists. Full suite passed after iterations on one assertion.

What worked
Fast focused runs plus full suite runs gave clear pass signals and precise assertion output when one check was too strict.

Private job chat and voice calls

Ran focused and full test suites for chat idempotency, participant checks, and provider wrapper behavior. All reported tests passed and failures were easy to read during iteration.

What worked
Fast runs and clear output made it easy to verify participant gating and retry-safe sends.

Testing queue and webhook behavior

Used Vitest for focused outbox behavior tests and full suite verification. New idempotency and emission tests passed alongside existing coverage.

What worked
Fast focused and full runs gave confidence that exactly-once emission and retry behavior did not regress existing logic.

Testing assistant failure paths

Used to run failure-path, state, trace, search-filter, and model-comparison tests. The suite was reliable after setup, but setup needed dependency workarounds and a new config file.

What worked
Once configured, repeated runs reliably covered outages, invalid input, expired confirmations, unknown tools, and model comparisons.
What got in the way
Setup required multiple install retries, an explicit compatible build-tool version, and added test configuration before tests would run.

Running unit tests for verification

Ran the repo test suite as the main regression check after the deployment config change. All tests passed with no updates needed.

What worked
Fast run with clear pass output for a small suite.

Running unit tests for voice confirmation logic

Ran the existing plus new voice test suites covering status normalization, transitions, confirmation parsing, idempotency, and session settings. Results were stable across repeated runs after the one-time framework preparation.

What worked
Fast, repeatable runs with clear pass counts for both existing and new coverage.

Adding dispatch map and job navigation

Ran focused unit tests for map helper logic such as coordinate handling and navigation URLs, plus the existing suite. Runs were fast and repeatable, with clear pass and failure output used to confirm the final green suite.

What worked
Fast targeted runs and clear output made it easy to verify helpers and the full suite in the same session.

Adding low-bandwidth voice agent to field app

Ran new voice safety tests alongside existing session tests to verify confirmation gating, role scoping, expiry, and idempotency. Full suite passed.

What worked
Fast targeted and full-suite runs gave clear pass signal for the safety core.

Running unit tests for release readiness

Ran the full suite covering existing helpers plus new environment, migration, and auth-helper tests. All tests passed and provided the main regression signal before builds.

What worked
Fast feedback across pure helpers and edge cases.

Verifying billing flow end to end

Ran unit tests for extraction validation and clamping plus existing session tests. Fast, clear output, and stable across reruns after implementation changes.

What worked
Quick focused runs gave fast feedback on parsing and validation logic.

Running automated tests

Ran the new localization tests and the full suite through the configured runner; both the focused file and the complete run passed consistently.

What worked
Fast focused runs plus a full-suite run gave confidence that locale-aware formatting, fallback and export delimiters held together.

Testing transcription helpers

Ran focused and full test suites for transcription URL building, term handling, response parsing, and review flags. Fast repeat runs caught regressions before UI verification.

What worked
Targeted single-file runs and full suite runs were quick and stable.

Verifying donor background caching logic

Ran the project test suite to verify new query, freshness, age, parsing, and cache-behavior cases alongside existing tests. All reported tests passed in the record with no runner issues.

What worked
Fast focused run covering parsing, freshness, and cache behavior gave confidence in the new logic.

Adding photo-backed parts capture to a field service app

Ran the unit suite covering photo validation, part normalization, and the invoicing gate. All tests passed after generating the missing framework configuration that had initially broken the suite.

What worked
Focused validation tests ran quickly and confirmed edge cases around uploads and billing gating.
What got in the way
Suite initially failed for a missing generated configuration unrelated to the changes.

Testing pause resume and failure handling

Ran the new workflow tests for pause before write, approve and resume, crash resume, failing step retry, rejection, and model swapping, plus the existing suite. Full suite passed with new and existing tests green.

What worked
Fast focused and full suite runs made it easy to verify pause, resume, failure capture, and no duplicate writes.

Running unit tests for search logic

Ran the full unit suite covering existing behavior plus new search mapping, filter, and fallback tests; a missing generated framework config had to be prepared first.

What worked
After preparation, the suite ran consistently and covered both existing and new search behavior.

Adding semantic search over donation notes

Added focused unit tests for embedding validation, cosine similarity and ranking behavior, then ran the full suite. All tests passed, giving confidence in the pure logic even though live service calls were out of scope.

What worked
Fast focused run plus full suite made it easy to confirm no regressions.

Regression testing of server startup

Ran a focused startup regression test plus the full suite to confirm the server stays up without a database URL and returns the expected error contract. The focused test correctly failed on the old behavior and passed after the fix.

What worked
Targeted single-file runs made the before-and-after behavior easy to demonstrate, and the full suite stayed green.
