xUnit.net

Ran tests for duplicate delivery, interrupted calls, ordering, rollback and recovery through the .NET test command. Failure reports helped identify a test-lock isolation issue. Final results showed 53 passing tests and two explicitly skipped SQL Server integration tests.

Ran existing and new unit tests for document generation and storage fallbacks; the full suite passed in the recorded session.

What worked

Fast focused tests plus full-suite run gave clear pass/fail signal.

Added focused tests for graduated tiers, ramps, commitment drawdown, credit expiry and exclusions, currency conversion, effective-date rates, and late-arrival restatements. Full suite passed.

What worked

Pure-function rating logic was straightforward to cover deterministically, including delta and versioned-close cases.

Added unit tests for auth enablement logic, authority format, validation flags, and misconfiguration rejection, then ran the full suite including existing tests.

What worked

New auth helper tests and the existing suite all passed together with no special setup.

Implemented the latency gate as a standard test using the repo's existing test framework, with warmup plus median-of-many timing and threshold logic. It ran fast, gave deterministic pass-fail behavior, and integrated with existing test filtering.

What worked

Fast execution and stable filtering made control versus injected-slowdown validation simple.

Added as the test framework for reconciliation and configuration guard tests covering lost rows, ragged data, totals checks, and region pinning. Full suite passed locally.

What worked

Test authoring was familiar and the runner reported results clearly through the SDK command line.

Used via the solution test run for conversion, webhook status mapping, card-data guard and persistence coverage alongside existing billing tests. The full suite passed and caught mapping regressions during iteration.

What worked

Fast focused tests for currency conversion, event-to-status mapping and persistence gave a clear pass signal before release.

Added an integration test project using the web host factory pattern to check that anonymous calls to all API surfaces are challenged, missing configuration stays fail-closed, and the health endpoint remains reachable. Tests failed in the expected way before the fix and passed afterward.

What worked

The host-based tests gave a fast, repeatable check for challenge status codes and configuration behavior without needing a live identity tenant.

What got in the way

Getting in-memory configuration overrides to reach the test host took extra diagnostic tests and rewrites of the test setup.

Ran the repository test suite plus new focused tests for email enqueue, idempotency, dispatch success, retry exhaustion, and delivery-report reconciliation. After fixing test scoping, the full suite passed.

What worked

Once scoping was fixed, tests were deterministic and clearly separated pre-existing coverage from new email behavior.

What got in the way

Initial tests hit scoped-context disposal errors that looked like product failures until the test setup was changed to use a scope factory.

Used xUnit categories to isolate a timing test for a representative service operation, running it alone for the slowdown and control comparison and again as part of the full suite.

What worked

Category filtering made it simple to prove the blocking behavior separately from correctness tests and then confirm no regression in the full run.

Relied on the existing unit testing framework to verify refactored calculation behavior and new batch cases for idempotency and skipped periods. The full local suite passed after the changes.

What worked

Existing tests caught regressions during namespace changes and new tests fit the same style easily.

Added focused unit tests for batch idempotency, period handling, and error cases and ran them via filtered and full-suite test runs until all tests passed.

What worked

Filtering by test name gave fast feedback and the full suite confirmed no regressions.

What got in the way

Initial test drafts needed several rewrites to cover idempotency, closed periods, and invalid input handling.

Added unit coverage for reconciliation rules and extractor region handling, including full-table acceptance, silent-drop blocking, sequence gaps, total mismatch, low confidence, and out-of-region rejection. All new tests passed in the verification run.

What worked

Small focused tests mapped directly to the fail-closed acceptance criteria and caught a controller behavior gap before final verification.

Relied on the existing test framework for the new timing-based regression test, running it isolated by name filter and again as part of the full suite.

What worked

Name filtering made it simple to prove the slowdown case failed and the control case passed without changing existing tests.

Added tests for day filtering, biased geocode queries and caching, plus a temporary probe to diagnose empty results. Final suite passed, but shared static throttle state caused cross-test interference during development.

What worked

Filtering and caching behavior was expressible with fake handlers and counting fakes.

What got in the way

Shared static state made tests order-sensitive until the test data and isolation were fixed.

Ran the existing ledger test and a new bridge suite covering webhook mapping accept and reject cases, burst drain with idempotent reconciliation, and amount mismatch handling. All tests passed in the observed runs.

What worked

Test output clearly separated the new suite from the existing suite, which made the pre-existing build fix easy to confirm.

Authored focused unit tests covering issuance gating, completion handling, decline and resend behavior, endorsement premium deferral, and webhook rejection. The full set passed.

What worked

Simple fact-based tests mapped directly to each gating and lifecycle rule.

Ran the existing unit suite plus new authorization tests covering scope variants, role acceptance, rejection cases, and fail-closed configuration. All tests passed and gave confidence that the new policies did not break calculator logic.

What worked

Fast deterministic tests for auth policy logic without needing network access or a live identity service.

Added focused unit tests for pin assembly, geocoder query handling and caching, and color assignment, following the repo's existing test style. Full suite passed including pre-existing tests.

What worked

Stub handlers, null loggers, and in-memory fakes made network-free tests for caching and edge cases simple.

Used the existing test framework to add a categorized performance test with warmup followed by repeated timed operations against seeded state, asserting against a committed baseline budget and writing structured evidence for review.

What worked

Category filtering cleanly separated fast unit tests from the perf gate, and assertion messages could direct users to evidence and re-baselining policy without extra tooling.

Wrote focused facts covering region acceptance and rejection, item storage, empty-result gap reporting, and the underwriter gate. All new tests passed through the standard runner.

What worked

Simple fact-based tests with clear failure messages made edge cases easy to pin down.

Ran the full solution test suite for completion enqueue, idempotency, worker send paths, and delivery report handling. Tests consistently reproduced two implementation bugs and passed after the fixes.

What worked

Failure output pointed to the relevant failing cases and made it practical to narrow scope to specific tests during debugging.

Used for new tests covering query construction, coordinate parsing, day filtering and cache persistence. All recorded tests passed alongside existing service tests.

What worked

Fact and theory style tests with faked message handlers and in-memory data made geocoder and mapping logic straightforward to assert.
