From 3c975a0fe852aafa0c2cb988aa9b6d93c959ba97 Mon Sep 17 00:00:00 2001 From: jsboige Date: Mon, 20 Jul 2026 07:42:08 +0200 Subject: [PATCH 1/3] fix(tests,#7225): document SK 1.78 planning-paradigm decision + re-model samples/Plans + update Skip reasons MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cycle c.699 (po-2025 worker, jsboigeEpita via jsboige push identity) — Option B deferred from #6853 (SK 1.78 migration Axe 2). Issue #7225 on jsboige/CoursIA is the tracker under #1210 Axe 3+; this commit lands the decision + the re-modeled JSON + the updated Skip reasons on the semantic-fleet side (jsboige/CoursIA bump-submodule-pointer PR follows separately after this is merged upstream). G.1 firsthand (C636/C638/C640) BEFORE editing confirmed the diagnosis: - `dotnet/src/IntegrationTests/Connectors/MultiConnector/ MultiConnectorTests.cs` (458 lines) exercises the legacy `Plan` planning model that was REMOVED in SK 1.78 (Plan.FromJson / plan.State / plan.Steps / SequentialPlanner.CreatePlanAsync returning a Plan). - The file also references `Microsoft.SemanticKernel.Connectors.AI. OpenAI.*` (legacy namespace, split into `.Connectors.OpenAI.*` in SK 1.78) AND the case-mismatched `samples/` paths that do not match the on-disk `Samples/` directory. - The 3 affected tests are `[Theory(Skip="manual verification")]` (never run in CI). The production MultiConnector path (`ExecuteAsync(KernelFunction)`, migrated in T2b `dece740`) already exercises the real functionality at the function level — so the *real* MultiConnector coverage exists; only the *plan-based* test is obsolete. Acceptance coverage (issue #7225): - #1 SK 1.78 planning paradigm chosen + documented → IntegrationTests.csproj decision block: hand-rolled `KernelFunction` pipeline (no external planner NuGet). Justification: tests are end-to-end integration probes, not unit tests of a planner; a hand-rolled chain keeps the assertion target (offloading cost, secondary connector vetting) isolated from planner- quality noise. - #2 samples/Plans/*.json re-modeled to the new format → both JSONs rewritten to a minimal `KernelFunction`-shaped schema (`schema_version`, `description`, `input_variable`, `default_input`, `steps[].function`, `steps[].parameters`, `steps[].outputs`). Readable by a future hand-rolled KernelFunction pipeline without re-parsing the legacy Plan JSON shape. - #3 Tests rewritten OR Skip with current reason → branch (b) chosen: all 3 `[Theory(Skip="This test is for manual verification.")]` updated to explicit, post-SK-1.78 reasons that name the blockers (Plan/namespace/path) and reference the csproj decision block + the re-modeled JSON. `` is KEPT because the file still references legacy namespaces and broken paths; the Skip annotations are dormant until a future PR lifts the Compile Remove and rewrites the test bodies. Documented in the csproj comment block + the PR body. - #4 dotnet build Semantic-Fleet-dotnet.sln stays at 0 errors → verified on the worktree: `dotnet build` = 0 Erreur(s), 28 Avertissement(s) (all pre-existing, unrelated to this change). - #5 dotnet test ≥ baseline (no regression) → verified: 4 tests discovered (OobaboogaCompletionTests skipped for manual verification, pre-existing); 0 regression. The 3 MultiConnectorTests stay out of discovery under ``, matching prior state. Scope of this PR is intentionally narrow (modest cross-famille grain): it lands the *decision* + the *data re-modeling* + the *Skip-reason refresh* that the issue asks for. The actual test-body rewrite against the hand-rolled `KernelFunction` pipeline is a follow-up that requires the legacy namespace + path fixes at the MultiConnector/MultiText CompletionSettings layer, out of scope for a single cycle.
