(e.g., dotnet.md for .NET, cpp.md for C++). Do not use directly — invoked

# Code Testing Extensions
This skill provides access to language-specific guidance files used by the code-testing pipeline. Call this skill to get the file paths, then read the relevant file for your target language.
## Available Extension Files
| File | Language | Contents |
|------|----------|----------|
| [extensions/dotnet.md](extensions/dotnet.md) | .NET (C#/F#/VB) | Build commands, test commands, project reference validation, common CS error codes, MSTest template |
| [extensions/python.md](extensions/python.md) | Python | Framework-adaptive test commands (pytest, custom runners), project layout detection, mocking guidelines, common errors |
| [extensions/typescript.md](extensions/typescript.md) | TypeScript/JavaScript | Build/test commands (Jest/Vitest/Mocha), framework detection, mocking, TS-specific considerations |
| [extensions/powershell.md](extensions/powershell.md) | PowerShell | Test commands (Pester v5), module import patterns, discovery/run pitfalls, mocking, common errors |
| [extensions/cpp.md](extensions/cpp.md) | C++ | Testing internals with friend declarations |

| [extensions/typescript-examples.md](extensions/typescript-examples.md) | TypeScript/JavaScript | Concrete pipeline examples (Vitest, applicable to Jest): research, plan, generated test file, fix cycles, final report |
| [extensions/go-examples.md](extensions/go-examples.md) | Go | Concrete pipeline examples (standard `testing`): research, plan, table-driven test file, fix cycles, final report |
| [extensions/java-examples.md](extensions/java-examples.md) | Java | Concrete pipeline examples (JUnit 5 + Mockito on Maven): research, plan, generated test file, fix cycles, final report |
## Usage
Read the appropriate base extension before writing test code. Load an
`<language>-examples.md` file only when the repository has no representative
tests and the base extension does not resolve the needed pattern. Do not load
end-to-end examples for a focused request with established local conventions.
