From db3d947a134bd49c2889f1d8b091d5b7cee17fea Mon Sep 17 00:00:00 2001 From: JerrettDavis Date: Tue, 28 Apr 2026 21:16:56 -0500 Subject: [PATCH 1/7] 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.

Each entry includes the rationale documented in the source file header. + +### EIP Composition Steps + +#### `ScatterGatherStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Composition/ScatterGatherStep.cs` | +| **Rationale** | PatternKit 0.105.0 does not expose a ScatterGather primitive. `AsyncActionComposite` supports parallel execution but lacks result-collection, per-branch error swallowing, and timeout/partial-result semantics implemented via `Task.WhenAll` + linked `CancellationTokenSource`. | +| **Test coverage** | `tests/WorkflowFramework.Tests.TinyBDD/Integration/Composition/ScatterGatherStepScenarios.cs` | +| **Revisit** | If a future PatternKit release adds a ScatterGather primitive with timeout semantics, evaluate in Phase G revision. | + +#### `AggregatorStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Composition/AggregatorStep.cs` | +| **Rationale** | PatternKit 0.105.0 has no Aggregator primitive. The completion condition logic (count, predicate, timeout) is unique to the EIP Aggregator pattern and cannot be modelled by any existing PatternKit behavioral or structural primitive without recreating all the logic. | +| **Test coverage** | Phase G.2 characterization tests | +| **Revisit** | PatternKit 0.106+ — check for Aggregator or CompletionStrategy primitive. | + +#### `SplitterStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Composition/SplitterStep.cs` | +| **Rationale** | `SplitterStep` splits an arbitrary context-provided collection into per-item parallel steps resolved at execution time. The per-item processed-output tracking (`__ProcessedItem` key) is not modelled by PatternKit. | +| **Test coverage** | Phase G.2 characterization tests | + +#### `ResequencerStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Composition/ResequencerStep.cs` | +| **Rationale** | Pure LINQ `OrderBy` over a context-provided collection. PatternKit 0.105.0 has no Resequencer or sort-pipeline primitive; adding a PatternKit wrapper would add indirection without any benefit. | +| **Test coverage** | Phase G.2 characterization tests | + +#### `ProcessManagerStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Composition/ProcessManagerStep.cs` | +| **Rationale** | PatternKit `AsyncStateMachine` requires all states and transitions to be declared at construction time. `ProcessManagerStep`'s state is determined dynamically by a delegate reading `IWorkflowContext`, and transitions occur when a handler mutates context (not by firing named events). This runtime-dynamic pattern cannot be expressed cleanly with PatternKit's compile-time state machine builder. | +| **Test coverage** | Phase G.2 characterization tests | + +#### `ComposedMessageProcessorStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Composition/ComposedMessageProcessorStep.cs` | +| **Rationale** | A pipeline of three dynamic operations (splitter→per-item-processor→aggregator) all sourced from context at runtime. No single PatternKit primitive composes this pattern without recreating the full logic. | +| **Test coverage** | Phase G.2 characterization tests | + +### EIP Routing Steps + +#### `RoutingSlipStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Routing/RoutingSlipStep.cs` | +| **Rationale** | PatternKit `AsyncActionChain` builds its pipeline at construction time from a fixed handler set. `RoutingSlip` selects the step registry and itinerary dynamically at runtime from `IWorkflowContext`. No PatternKit primitive cleanly models a dynamic, state-advancing chain; keeping bespoke avoids a leaky abstraction. | +| **Test coverage** | `tests/WorkflowFramework.Tests.TinyBDD/Integration/Routing/RoutingSlipStepScenarios.cs` | + +#### `DynamicRouterStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Routing/DynamicRouterStep.cs` | +| **Rationale** | The routing function can return a different step each iteration based on evolving context state (a feedback loop). PatternKit Strategy/Chain patterns pre-bake the route set at construction time and cannot model this runtime-adaptive routing. | +| **Test coverage** | Phase G.1 characterization tests | + +#### `RecipientListStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Routing/RecipientListStep.cs` | +| **Rationale** | `AsyncActionComposite` requires child actions to be known and registered at build time. Recipients are resolved dynamically from `IWorkflowContext` at execution time via a delegate. | +| **Test coverage** | Phase G.1 characterization tests | + +#### `MessageFilterStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Routing/MessageFilterStep.cs` | +| **Rationale** | Single-predicate step (predicate → abort-or-continue). PatternKit.Core 0.105.0 does not expose a standalone Specification type; Behavioral.Strategy primitives are overkill for a single boolean predicate. | +| **Test coverage** | Phase G.1 characterization tests | + +### EIP Channel Steps + +#### `ChannelAdapterStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Channel/ChannelAdapterStep.cs` | +| **Rationale** | PatternKit `AsyncAdapter` is a type-mapping pattern (produce `TOut` from `TIn`). `ChannelAdapterStep` is a side-effect operation (send/receive via `IChannelAdapter`). The send/receive contract doesn't fit the adapt-a-type signature. | +| **Test coverage** | Phase G.3 characterization tests | + +#### `WireTapStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Channel/WireTapStep.cs` | +| **Rationale** | Core contract (run a side-effect without disrupting the main flow, with optional error swallowing) is simpler than PatternKit's `AsyncActionDecorator` pipeline. `AsyncActionDecorator` wraps a component and transforms/intercepts results; `WireTapStep` purely fires-and-forgets a side channel. | +| **Test coverage** | Phase G.3 characterization tests | + +#### `MessageBridgeStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Channel/MessageBridgeStep.cs` | +| **Rationale** | Receives from one `IChannelAdapter` and sends to another in a single atomic step. PatternKit Bridge connects two hierarchies abstractly (implementation vs abstraction); it does not model a runtime channel receive→forward pipeline. Two-call thin wrapper; no PatternKit primitive reduces the code further. | +| **Test coverage** | Phase G.3 characterization tests | + +#### `DeadLetterStep` + +| Item | Detail | +|------|--------| +| **File** | `src/WorkflowFramework.Extensions.Integration/Channel/DeadLetterStep.cs` | +| **Rationale** | Extracts the dead-letter payload from context and routes it to an `IDeadLetterStore`. PatternKit 0.105.0 has no dead-letter or error-routing primitive. PatternKit Decorator transforms inputs; it does not catch exceptions and route them to external stores. | +| **Test coverage** | Phase G.3 characterization tests | + +--- + +## Decision Criteria + +When evaluating a bespoke component for PatternKit adoption, the following criteria guide the decision: + +1. **Does a matching PatternKit primitive exist?** If no matching primitive exists in the current version, keep bespoke and document. +2. **Does adoption remove real complexity?** If wrapping the primitive requires the same or more code, adoption adds indirection without benefit. Keep bespoke. +3. **Is the behavior determined at construction time or runtime?** PatternKit primitives (Chain, Composite, Strategy) typically require their structure to be declared at construction. Steps that build their structure dynamically from `IWorkflowContext` at execution time are a poor fit. +4. **Is the public API preserved?** Adoption must be internal-only. Any public type or method signature change requires a separate API-evolution PR. +5. **Does characterization test coverage exist first?** No adoption without a TinyBDD scenario set that pins current behavior. + +--- + +## Future Evaluation Targets + +The following components are candidates for PatternKit adoption in later phases if suitable primitives become available: + +| Component | Potential Primitive | Blocking Reason Today | +|-----------|--------------------|-----------------------| +| `AggregatorStep` | PatternKit Aggregator (future) | No primitive in 0.105.0 | +| `ScatterGatherStep` | PatternKit ScatterGather (future) | No primitive in 0.105.0 | +| `PluginManager` | `Strategy` + `AbstractFactory` | Phase H.8 — not yet started | +| `AgentLoopStep` / `AgentDecisionStep` | TypeDispatcher | Phase H.7 — not yet started | +| `ResilienceMiddleware` (Polly) | `RetryPolicy` | Phase F pilot option B — deferred | From 6e146abfcfee241201c484871148b9058eea49f4 Mon Sep 17 00:00:00
