- ProposalConcurrencyTests (shared-connection SQLite, two competing
writers): stale-token pre-check with embedded currentState, DB-level
lost race reloading the winner's values, 422 token codes, version
bump on success, bulk-update proposal-token guard, line-item create
bumping the aggregate, audit rows never persisted on a lost race.
- GlobalExceptionHandlerTests: pin both SHOC 409 envelopes verbatim
(guarded { message, currentState } incl. null state; fallback
{ status, message, code }) and assert shape exclusivity.
- RowVersionCodecTests: round-trip, SHOC-style token literal,
malformed/wrong-length rejection.
- Existing suites threaded with live version tokens (Ver helper);
audit assertions moved from LogAsync to Stage.
187 xUnit green (was 166).
- ProposalNumberGenerator tests (8 tests): format validation (SHI-YYYY-NNNN),
sequence incrementing, revision skipping, year boundary isolation, uniqueness,
zero-padding, high sequence rollover. Uses SQLite in-memory with Postgres
function stubs to support ExecuteSqlRawAsync.
- LineItemService state guard tests (18 tests): verifies line items cannot be
created/bulk-updated/deleted on Approved or Sent proposals (QA-C2), confirms
operations succeed on InReview and Revised statuses, validates
KeyNotFoundException on missing proposals, verifies audit logging.
- API client interceptor tests (14 tests): request interceptor attaches Bearer
token from sessionStorage (WEB-C1), handles missing/malformed token data,
response interceptor dispatches Redux logout on 401 (WEB-M2), returns friendly
messages for 403/404, extracts server error details, handles network errors.
- DbContextFactory updated to suppress InMemoryEventId.TransactionIgnoredWarning
so BulkUpdateAsync tests work with in-memory provider.
- Added SqliteDbContextFactory for tests requiring relational features.
- Added Microsoft.EntityFrameworkCore.Sqlite to test project dependencies.
Total: 104 .NET tests (was 77), 26 web tests (was 12). CI already wired.
