metadata: version: "1.0.0" author: "Lerian Studio" category: development trigger: - After implementation and SRE complete (Gate 0/1/2) - Task has acceptance criteria requiring test coverage - Need to verify implementation meets requirements sequence: after: [ring:dev-implementation, ring:dev-devops, ring:dev-sre] before: [ring:requesting-code-review]

Dev Testing (Gate 3)

Overview

Ensure every acceptance criterion has at least one unit test proving it works. Follow TDD methodology: RED (failing test) -> GREEN (implementation) -> REFACTOR.

Core principle: Untested acceptance criteria are unverified claims. Each criterion MUST map to at least one executable unit test.

Coverage threshold: 85% minimum (Ring standard). PROJECT_RULES.md can raise this threshold, not lower it.

If PROJECT_RULES.md not found: Use Ring default (85%). Optionally offer to create from {OPENCODE_CONFIG}/templates/PROJECT_RULES.md.

Role Clarification

This skill ORCHESTRATES. QA Analyst Agent EXECUTES.

Required Input

• unit_id: Task/subtask being tested
• acceptance_criteria: List of ACs to test
• implementation_files: Files from Gate 0
• language: go / typescript / python

Dispatch QA Analyst Agent

  description: "Write unit tests for [unit_id]"
  prompt: |
    WRITE UNIT TESTS for All Acceptance Criteria

    ## Context
    - Unit ID: [unit_id]
    - Language: [language]
    - Coverage Threshold: [coverage_threshold]%

    ## Acceptance Criteria to Test
    [list with AC-1, AC-2, etc.]

    ## Implementation Files to Test
    [implementation_files]

    ## Requirements

    ### Test Coverage
    - Minimum: [coverage_threshold]% branch coverage
    - Every AC MUST have at least one test
    - Edge cases REQUIRED

    ### Test Naming
    - Go: Test{Unit}_{Method}_{Scenario}
    - TS: describe('{Unit}', () => { it('should {scenario}', ...) })

    ### Edge Cases Required per AC Type
    | AC Type | Required Edge Cases | Minimum |
    |---------|---------------------|---------|
    | Input validation | null, empty, boundary | 3+ |
    | CRUD operations | not found, duplicate | 3+ |
    | Business logic | zero, negative, overflow | 3+ |

    ## Required Output

    ### Coverage Report
    | Package/File | Coverage |
    |--------------|----------|
    | **TOTAL** | **[X%]** |

    ### Traceability Matrix
    | AC ID | Criterion | Test File | Test Function | Status |
    |-------|-----------|-----------|---------------|--------|

    ### Quality Checks
    | Check | Status |
    |-------|--------|
    | No skipped tests | ✅/❌ |
    | Edge cases per AC | ✅/❌ |

    ### VERDICT
    **Coverage:** [X%] vs Threshold [Y%]
    **VERDICT:** PASS / FAIL
