MockPanel only handled the v2 (single-slot, request/reply) UploadProgram path. v1 panels use a streaming variant: client sends UploadPrograms (bare), panel emits one ProgramData per defined slot, ack-walked by the client, terminated by EOD. Wire layout is byte-identical to v2 — only the envelope opcode and stream pattern differ (clsHAC.OL1ReadConfig at clsHAC.cs:4403, 4538-4540, 4642-4651). The mock now mirrors the UploadNames streaming pattern with its own cursor. Tests cover both the populated-state stream-then-EOD case and the empty-state immediate-EOD case, alongside the existing v2 single-slot round-trip tests.

"""End-to-end wire round-trip: client → MockPanel → program decoded.
|
|
|
|
Seeds the MockPanel with known :class:`Program` records, exercises
|
|
both wire dialects, and asserts the decoded result equals what was
|
|
seeded.
|
|
|
|
* v2 (TCP, request/response per slot): drives ``UploadProgram`` once
|
|
per slot. Proves the per-program framing (2-byte BE ProgramNumber +
|
|
14-byte body wrapped in a ``ProgramData`` reply).
|
|
* v1 (UDP, streaming): drives bare ``UploadPrograms``, ack-walks the
|
|
streamed ``ProgramData`` replies to ``EOD``. Proves the streaming
|
|
lock-step matches the panel's behaviour described in
|
|
``clsHAC.OL1ReadConfig`` (clsHAC.cs:4403, 4538-4540, 4642-4651).
