Audits .NET test mock usage by tracing each mock setup through the production code's execution path to find dead, unreachable, redundant, or replaceable mocks. Use when the user asks to audit mock usage, find unused or unnecessary mock setups, check if mocks are needed, reduce mock duplication or over-mocking, simplify test setup, or review whether mock configurations like ILogger/IOptions should use real implementations instead. Supports Moq, NSubstitute, and FakeItEasy.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mock Usage Analysis Trace each mock setup through the production code's execution path to determine which setups are actually exercised at runtime and which are dead, unreachable, redundant, or replaceable with real implementations. ## When to Use - User asks to audit, review, or analyze mock usage in .NET tests - User wants to find unused, unnecessary, or redundant mock setups - User wants to simplify test setup or reduce over-mocking - User asks whether mocks of ILogger, IOptions, or similar types are needed ## When Not to Use - User wants to write new mocks or tests (general testing guidance) - User wants to detect non-mock test anti-patterns (use `test-anti-patterns`) - User wants to migrate between mock frameworks (out of scope) ## Inputs | Input | Required | Description | |-------|----------|-------------| | Test code | Yes | Test files to analyze | | Production code | Yes | Code under test — essential for tracing execution paths | ## Workflow ### Step 1: Read all provided code Read the test files and **always** read the production code. You cannot determine whether a mock setup is necessary without understanding the production method's control flow. …

How to install
mdr add dotnet/skills/exp-mock-usage-analysis@sha256:95f041cab6474516The line at the top of this page pins the label git:20260421.05aeb65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
