run-conformance-from-branch

# Run Conformance From Branch Run C# SDK conformance tests against an unpublished `modelcontextprotocol/conformance` branch (including branches in forks). ## Use Cases - Validate a conformance PR before it is published to npm - Validate C# SDK behavior against a fork with custom scenario changes - Reproduce failures caused by conformance changes ## Safety / Repo Hygiene 1. Start from a clean git state. 2. Commit or stash local changes first. 3. Restore pinned dependencies when done (`npm ci`). ## Inputs - **Source type**: `upstream-branch` or `fork-branch` - **Source locator**: - Upstream branch: `modelcontextprotocol/conformance#<branch>` - Fork branch: `<owner>/conformance#<branch>` - **Scenario** (optional): e.g. `auth/scope-step-up` ## Workflows ### A) Install directly from GitHub branch (upstream or fork) From `csharp-sdk` root: ```bash npm install --no-save @modelcontextprotocol/conformance@github:<owner>/conformance#<branch> ``` Examples: ```bash npm install --no-save @modelcontextprotocol/conformance@github:modelcontextprotocol/conformance#main npm install --no-save @modelcontextprotocol/conformance@github:myuser/conformance#sep-2350-check ``` ## Run Tests ### Run client conformance tests with dotnet test filter: ```bash dotnet test tests/ModelContextProtocol.AspNetCore.Tests/ModelContextProtocol.AspNetCore.Tests.csproj -f net10.0 --filter "FullyQualifiedName~ClientConformanceTests" ``` ### Run server conformance tests with dotnet test filter: ```bash dotnet test tests/ModelContextProtocol.AspNetCore.Tests/ModelContextProtocol.AspNetCore.Tests.csproj -f net10.0 --filter "FullyQualifiedName~ServerConformanceTests" ``` ## Reporting Always report: 1. Installed conformance source (`npm ls @modelcontextprotocol/conformance --depth=0`) 2. Scenario results (pass/fail/warnings) 3. Any new check IDs observed (for traceability) ## Cleanup / Restore Return repo to pinned dependency state: ```bash npm ci ```
