From db3d947a134bd49c2889f1d8b091d5b7cee17fea Mon Sep 17 00:00:00 2001 From: JerrettDavis Date: Tue, 28 Apr 2026 21:16:56 -0500 Subject: [PATCH 1/8] chore(tests): switch Ollama model to qwen2.5:1.5b, enforce serial E2E execution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace qwen3:30b-instruct with qwen2.5:1.5b (1.5B params, <=2B constraint) everywhere the model is configured: OllamaAgentProvider default, OllamaFixture, SemanticKernelE2ETests, AiDsl sample, TaskStream sample extension - Reduce OllamaFixture warmup timeout from 300s to 120s; remove /no_think from warmup prompt (qwen3-specific; harmless on qwen2.5 but unnecessary) - Add xunit.runner.json to Tests.E2E with parallelizeTestCollections:false and maxParallelThreads:1 – combined with the existing [Collection("Ollama")] attribute this guarantees all Ollama-backed tests run one at a time - Update OllamaFactAttribute skip message to reference new model - Update OllamaOptionsTests default model assertion to match new default - Update prerequisite XML doc comment in AgentLoopOllamaE2ETests To run the Ollama-backed E2E tests locally: ollama pull qwen2.5:1.5b dotnet test tests/WorkflowFramework.Tests.E2E/WorkflowFramework.Tests.E2E.csproj \ --filter Category=E2E Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../Program.cs | 227 ++++++++++++++++++ .../Extensions/ServiceCollectionExtensions.cs | 2 +- .../OllamaAgentProvider.cs | 2 +- .../AgentLoopOllamaE2ETests.cs | 76 ++++++ .../OllamaFixture.cs | 36 ++- .../SemanticKernelE2ETests.cs | 2 +- .../WorkflowFramework.Tests.E2E.csproj | 3 + .../xunit.runner.json | 5 + .../Extensions/AI/OllamaAgentProviderTests.cs | 2 +- 9 files changed, 348 insertions(+), 7 deletions(-) create mode 100644 samples/WorkflowFramework.Samples.AiDsl/Program.cs create mode 100644 tests/WorkflowFramework.Tests.E2E/xunit.runner.json diff --git a/samples/WorkflowFramework.Samples.AiDsl/Program.cs b/samples/WorkflowFramework.Samples.AiDsl/Program.cs new file mode 100644 index 0000000..2155345 --- /dev/null +++ b/samples/WorkflowFramework.Samples.AiDsl/Program.cs @@ -0,0 +1,227 @@ +using System.Text.Json; +using WorkflowFramework; +using WorkflowFramework.Extensions.AI; +using WorkflowFramework.Serialization; + +// ───────────────────────────────────────────────────────────────────────────── +// DSL-Emitter Pattern Demo +// +// This sample demonstrates how an LLM can dynamically emit workflow steps as +// JSON, which are then reviewed by a human and executed at runtime. +// +// Flow: +// 1.

Seeded workflow (open-existing list): id=sample-ai-dsl-emitter, name="AI DSL Emitter", immediately visible in the workflow list on startup.

Migrate to PatternKit.Messaging.Transformation .IClaimCheckStore. LegacyClaimCheckStoreAdapter bridges old implementations for one release; it will be removed in the next major version. BEHAVIOR CHANGE: ClaimCheckStep now generates its own claim ID (Guid.NewGuid().ToString("N")) rather than accepting one from the caller. The ID is stored under ClaimTicketKey as before. Tests updated to assert the ticket is non-null/non-empty rather than a caller-supplied value.

The shared-context mutation pattern (__Result_{Name} keys) is removed — it was a concurrency hazard with no isolation. OBSOLETION: The IEnumerable constructor overload is now [Obsolete] and bridges to the typed API for one release. Migrate to ScatterGatherStep.Recipient. BEHAVIOR CHANGE (OperationCanceledException): PatternKit swallows non-caller- initiated OperationCanceledException without adding a failure envelope. A cancelled branch produces 0 results, not a null entry in results. Tests updated accordingly. BEHAVIOR CHANGE (result ordering): PatternKit uses ConcurrentBag internally; result order is non-deterministic. Tests changed from index-based to predicate assertions (ContainSingle) where ordering assumptions existed.

Each recipient is a typed `ScatterGatherStep.Recipient` (name + `Func>`) that returns its result directly — eliminating the shared-context mutation hazard. Results are aggregated into `ResultsKey` as before. | +| **Phase introduced** | feat/iter2-major-interface-migrations (Phase 3) | +| **Behavior change** | **Breaking (back-compat provided):** Recipient contract changes from `IStep` (mutates shared context, reads `__Result_{name}`) to typed `Recipient` (returns value directly). PatternKit's `ConcurrentBag` means result ordering is non-deterministic (was implicit-sequential before). Non-caller-cancelled recipients produce NO result entry (previously produced null). A deprecated `IEnumerable` overload bridges for one release. | +| **Test coverage** | `tests/WorkflowFramework.Tests.TinyBDD/Integration/Composition/ScatterGatherStepScenarios.cs` + `ScatterGatherStepTests.cs` — all scenarios updated; `HandlerOperationCanceledException_IsSwallowed` updated with rationale comment. | +| **Public API change** | New typed constructor `ScatterGatherStep(IEnumerable, ...)` is primary. Legacy `IEnumerable` overload is `[Obsolete]`, retained for one release. Builder `ScatterGather(IEnumerable, ...)` is now primary; legacy overload deprecated. | +| **Net delta** | −28 LOC bespoke fan-out/error-isolation logic replaced by PatternKit primitive. | +| **Obsoletion** | `ScatterGatherStep(IEnumerable, ...)` constructor overload → `ScatterGatherStep(IEnumerable, ...)`.
