description	DDE subordinate extension. C++ test design/execution workflow (CMake/CTest/gtest) with strict DDE write gating.

DDE Extension: C++ Testing

Skill Version: v0.1

Authority Chain

• Commander: dde-bootstrap
• Write gate: dde-code-guard
• This skill cannot directly bypass [APPROVED] for code writes.

When to Use

• Add/fix C++ tests
• Investigate C++ test failures/flakiness
• Improve C++ regression coverage

Execution Scope

Allowed:

• Analyze C++ test gaps
• Propose/prepare test cases and CTest targets
• Run CMake/CTest/gtest commands
• Produce failure diagnosis

Write-sensitive actions:

• Creating/modifying *.cpp, *.h, CMakeLists.txt, test files
• Must go through handoff + dde-code-guard

Mandatory Flow

1. Identify target component and expected behavior.
2. Map existing tests and missing cases.
3. Run focused tests first, then suite.
4. If changes required, emit handoff:

DDE_EXTENSION_HANDOFF_REQUIRED

Fields:

• Reason
• Files to modify
• Proposed test cases
• Minimal impact statement

5. Wait for [APPROVED] via dde-code-guard before write.

Output Contract

• Test gap summary
• Command results summary
• Proposed test patch plan
• Handoff block when write is needed
