A parity guard already existed for DriverTypeNames <-> the /raw driver picker,
but not for the two dispatch maps downstream, so a driver could be registered,
offered in the picker, and then have no config form. That is exactly what
happened to Calculation (G-1) and to Sql/MTConnect/Calculation on the device
modal (G-2) — both survived review because nothing could see them.
The maps had to become data first. A Razor @switch compiles into
BuildRenderTree's IL, so no test can enumerate its cases; the picker guard
works only because RawDriverTypeDialog keeps its data in a field the markup
enumerates. Both modals now render from DriverConfigFormMap / DeviceFormMap
through <DynamicComponent>, and being public those maps need none of the
picker test's BindingFlags.NonPublic fragility.
- G-1 CalculationDriverForm.razor — RunTimeout was unauthorable via the UI.
- G-2 Sql/MTConnect/Calculation declared single-connection rather than given
hollow device forms; each holds one connection at the driver level.
- G-3 DriverConfigModal's hardcoded "Galaxy or Mqtt" -> IsSingleConnection, so
Sql/MTConnect authors are no longer sent to a device form with no endpoint.
- G-4 DriverFormMapParityTests (5, both directions) + DriverDispatchMapParityTests.
- G-5 CsvColumnMap entries for Sql, Mqtt, MTConnect.
- G-6 RawBrowseCommitMapper Sql branch — and the browser end, which the audit
missed: SqlBrowseSession emitted NO AddressFields, so a browsed leaf carried
only a column name, and a column alone cannot address a Sql tag. It now
travels schema/table/column and the mapper builds a WideRow config from them.
A branch alone would have produced a half-built blob.
Two findings while writing the guards. The G-6 test showed Modbus and
Calculation also hit the generic address fallback — correctly, as neither is
browsable — so it asserts the fall-through set EQUALS a documented
non-browsable list in both directions; a one-way check would let a newly
browsable driver be quietly added to the exclusion list. And
TagConfigDriverTypeNameGuardTests was hollow: it enumerated a hand-written
TheoryData that had already drifted (omitting Galaxy, Sql and Mqtt), guarding
renames but not gaps. Now enumerated from the map with a coverage test facing
the other way.
Live-verified on docker-dev, since this repo has no bUnit and no unit test
reaches Blazor parameter binding: opened Calculation's config (previously "No
typed config form"), typed 3500, saved, reopened — the value persisted, so the
DynamicComponent two-way binding round-trips. Sql's form renders fully and now
reads "This driver holds a single connection, authored above".
AdminUI.Tests 930 passed.
