- 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.
