This tool queries the IDE code coverage data directly and is:\n\n- **Precise** — returns exact test locations without false positives\n- **Token-efficient** — no need for glob, grep, or directory listing guesses\n- **Fast** — a single call replaces multiple rounds of searching\n\n## `findTests`\n\nFind existing tests for a given production class and method.

Class only — no method name\nUser says: \"Find the tests for the `JsonSerializer` class\"\n\n```json\n{\"tool\":\"execute_tool\",\"arguments\":{\"command\":\"findTests --className JsonSerializer --classNamespace Newtonsoft.Json --filePath \u002Fprojects\u002FNewtonsoft.Json\u002FSrc\u002FNewtonsoft.Json\u002FJsonSerializer.cs\"}}\n```\n\n#### 2. With method name\nUser says: \"Find tests for the `Deserialize` method in `JsonSerializer`\"\n\n```json\n{\"tool\":\"execute_tool\",\"arguments\":{\"command\":\"findTests --className JsonSerializer --classNamespace Newtonsoft.Json --filePath \u002Fprojects\u002FNewtonsoft.Json\u002FSrc\u002FNewtonsoft.Json\u002FJsonSerializer.cs --methodName Deserialize\"}}\n```\n\n#### 3. With method name and arg names — specific overload\nUser says: \"Find tests for the `Deserialize(TextReader reader, Type objectType)` overload in `JsonSerializer`\"\n\n```json\n{\"tool\":\"execute_tool\",\"arguments\":{\"command\":\"findTests --className JsonSerializer --classNamespace Newtonsoft.Json --filePath \u002Fprojects\u002FNewtonsoft.Json\u002FSrc\u002FNewtonsoft.Json\u002FJsonSerializer.cs --methodName Deserialize --methodArguments 'TextReader reader, Type objectType'\"}}\n```\n\n#### 4. Generic class and method\nUser says: \"Find tests for the `ReadJson\u003CTResult>` method in `JsonConverter\u003CT>`\"\n\n```json\n{\"tool\":\"execute_tool\",\"arguments\":{\"command\":\"findTests --className 'JsonConverter\u003CT>' --classNamespace Newtonsoft.Json --filePath \u002Fprojects\u002FNewtonsoft.Json\u002FSrc\u002FNewtonsoft.Json\u002FJsonConverter.cs --methodName 'ReadJson\u003CTResult>'\"}}\n```\n\n#### 5. Paths with spaces\n```json\n{\"tool\":\"execute_tool\",\"arguments\":{\"command\":\"findTests --className DnsClient --classNamespace My.Network.Clients --filePath '\u002FUsers\u002Fdev\u002FMyProject\u002Fsrc\u002FNetwork Clients\u002FDnsClient.cs' --methodName ResolveAsync\"}}\n```\n\n### Pitfalls\n\n- Every `--param` MUST be followed by a value (no bare flags)\n- Values with spaces must be quoted: `--filePath '\u002FUsers\u002Fdev\u002FMyProject\u002Fmy folder\u002Ffile.cs'`\n- Omit optional parameters entirely rather than passing empty strings\n- All file paths must be absolute\n\n## Rules\n\n1. **C# only.** Before invoking `findTests`, verify the production file is `.cs`. If it is any other language, do not invoke this skill or its tool — skip silently and fall back to standard test discovery.\n2. **Prefer `findTests` over glob, grep, or directory listing** to find tests in C# code. These are wasteful and imprecise. If `execute_tool` is unavailable, fall back to grep\u002Fglob as a last resort and inform the user.\n3. If `findTests` reports no tests exist, trust that result — do not retry with alternative search tools.\n4. After finding tests, read them to understand the project's testing conventions before making any changes.\n\n## Troubleshooting\n\n### execute_tool not available\nIf `execute_tool` is not available, inform the user and fall back to grep\u002Fglob only as a last resort.\n\n### `findTests` via `execute_tool` timeout\nIf calling `findTests` via `execute_tool` times out, inform the user and fall back to your standard test discovery method.\nYou may stop trying `findTests` if it timeouts for three times in a row.\n\n### No tests found\nIf `findTests` returns empty results, trust the result. Do not retry with alternative search methods.\n",{"data":36,"body":38},{"name":4,"description":6,"allowed-tools":37},"execute_tool",{"type":39,"children":40},"root",[41,50,62,83,118,128,133,140,152,158,352,368,374,381,394,506,512,531,626,632,650,745,751,769,864,870,965,971,1008,1014,1084,1090,1096,1107,1125,1150,1156,1167],{"type":42,"tag":43,"props":44,"children":46},"element","h1",{"id":45},"finding-existing-tests",[47],{"type":48,"value":49},"text","Finding Existing Tests",{"type":42,"tag":51,"props":52,"children":53},"p",{},[54,60],{"type":42,"tag":55,"props":56,"children":57},"strong",{},[58],{"type":48,"value":59},"Applies to: C# code only.",{"type":48,"value":61},"\nIf the production code in question is not C# - do not use this skill.
