Project: ManagedCode.Storage.TestFakes Owned by: ManagedCode.Storage maintainers

Parent: ../AGENTS.md

• Provides fake storage implementations and helper extensions used by the repository integration tests.
• Exists so tests can exercise storage flows without coupling production packages to test-only doubles.

• FakeAWSStorage.cs
• FakeAzureStorage.cs
• FakeGoogleStorage.cs
• MockCollectionExtensions.cs

• In scope: test-only storage doubles and helper registration utilities
• Out of scope: production package behavior, public NuGet-facing APIs, and docs-site content
• Protected or high-risk areas: behavioral parity with the real provider contracts used by the test suite

• build: dotnet build ManagedCode.Storage.TestFakes.csproj
• test: dotnet test ../Tests/ManagedCode.Storage.Tests/ManagedCode.Storage.Tests.csproj --configuration Release
• format: dotnet format ../ManagedCode.Storage.slnx
• Active test framework: xUnit
• Runner model: VSTest
• Analyzer severity lives in the repo-root .editorconfig.

• mcaf-dotnet
• mcaf-testing
• mcaf-dotnet-xunit
• mcaf-dotnet-quality-ci

• Stricter maintainability limits: none; inherit the root defaults.
• Required local docs: docs/Architecture.md, README.md, and the nearest feature or ADR docs when public behavior changes.
• Local exception policy: inherit the root exception_policy and document any project-specific exception in the nearest ADR, feature doc, or local AGENTS.md.

• Keep fake behavior aligned with the public provider contracts and external API shapes that tests rely on.
• Do not let test-only helpers leak into production projects or samples.
• Prefer small targeted fakes over broad behavior switches that make assertions ambiguous.
