Validates test coverage and quality by checking behavior focus, identifying gaps, and ensuring >80% statement coverage. Use when task file is in testing/ directory and requires test validation before marking complete. Adds minimal tests for genuinely missing edge cases.
/plugin marketplace add dhruvbaldawa/ccconfigs/plugin install experimental@ccconfigsThis skill inherits all available tools. When active, it can use any tool Claude has access to.
Given task file path .plans/<project>/testing/NNN-task.md:
Use TodoWrite to track testing validation:
☐ Validate existing tests (behavior-focused?)
☐ Check coverage of Validation checklist items
☐ Identify gaps (empty/null, boundaries, errors)
☐ Add tests for genuine gaps
☐ Run coverage (>80% statements, >75% branches)
☐ Update task status
**Status:** [current status]**Status:** READY_FOR_REVIEW**testing:**
Validated [N] tests (behavior-focused)
Added [M] edge cases:
- [Test description]
- [Test description]
Test breakdown: Unit: X | Integration: Y | Total: Z
Coverage: Statements: XX% | Branches: XX% | Functions: XX% | Lines: XX%
Full suite: XXX/XXX passing
Working Result verified: ✓ [description]
Good: expect(response.status).toBe(401) (tests behavior)
Bad: expect(bcrypt.compare).toHaveBeenCalled() (tests implementation)
Granularity: Pure functions → Unit | DB/API → Integration | Critical workflows → E2E (rare)
If tests fail or coverage <80%:
**Status:** [current status] → Replace **Status:** NEEDS_FIX**testing:**
Found issues:
- [Specific issue]
- [Specific issue]
Requires code fixes. Moving back to implementation.
When testing is complete (status updated to READY_FOR_REVIEW or NEEDS_FIX):
✅ Testing complete. Status: [STATUS]This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
