Dev Testing (Consolidated: Gates 3-7)

This skill consolidates the 5 testing gates from the Ring development cycle. In the official Ring, these are separate skills (dev-unit-testing, dev-fuzz-testing, dev-property-testing, dev-integration-testing, dev-chaos-testing). This consolidated version provides all testing gate content in a single file for OpenCode compatibility.

Gate 3: Unit Testing

Dev Unit 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, not lower.

CRITICAL: Role Clarification

This skill ORCHESTRATES. QA Analyst Agent EXECUTES.

Step 1: Validate Input

REQUIRED INPUT (from ring:dev-cycle orchestrator):
<verify_before_proceed>
- unit_id exists
- acceptance_criteria is not empty
- implementation_files is not empty
- language is valid (go|typescript|python)
</verify_before_proceed>

```text
- unit_id: [task/subtask being tested]
- acceptance_criteria: [list of ACs to test]
- implementation_files: [files from Gate 0]
- language: [go|typescript|python]

OPTIONAL INPUT:
- coverage_threshold: [default 85.0, cannot be lower]
- gate0_handoff: [full Gate 0 output]
- existing_tests: [existing test files]

if any REQUIRED input is missing:
  → STOP and report: "Missing required input: [field]"
  → Return to orchestrator with error

if coverage_threshold < 85:
  → STOP and report: "Coverage threshold cannot be below Ring minimum (85%)"
  → Use 85% as threshold

Step 2: Initialize Testing State

testing_state = {
  unit_id: [from input],
  coverage_threshold: max(85, [from input]),
  coverage_actual: null,
  verdict: null,
  iterations: 0,
  max_iterations: 3,
  traceability_matrix: [],
  tests_written: 0
}

Step 3: Dispatch QA Analyst Agent

Task:
  subagent_type: "ring:qa-analyst"
  description: "Write unit tests for [unit_id]"
  prompt: |
    ⛔ WRITE UNIT TESTS for All Acceptance Criteria

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

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

    ## Implementation Files to Test
    [list implementation_files]

    ## Standards Reference
    For Go: https://raw.githubusercontent.com/LerianStudio/ring/main/dev-team/docs/standards/golang.md
    For TS: https://raw.githubusercontent.com/LerianStudio/ring/main/dev-team/docs/standards/typescript.md

    Focus on: Testing Patterns section

    ## Requirements

    ### Test Coverage
    - Minimum: [coverage_threshold]% branch coverage
    - Every AC MUST have at least one test
    - Edge cases REQUIRED (null, empty, boundary, error conditions)

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

    ### Test Structure
    - One behavior per test
    - Arrange-Act-Assert pattern
    - Mock all external dependencies
    - no database/API calls (unit tests only)

    ### Edge Cases Required per AC Type

    <cannot_skip>
    - Minimum 3 edge cases per AC type
    - null, empty, boundary conditions required
    - Error conditions required
    </cannot_skip>

    | AC Type | Required Edge Cases | Minimum |
    |---------|---------------------|---------|
    | Input validation | null, empty, boundary, invalid format | 3+ |
    | CRUD operations | not found, duplicate, concurrent | 3+ |
    | Business logic | zero, negative, overflow, boundary | 3+ |
    | Error handling | timeout, connection failure, retry | 2+ |

    ## Required Output Format

    ### Test Files Created
    | File | Tests | Lines |
    |------|-------|-------|
    | [path] | [count] | +N |

    ### Coverage Report
    **Command:** [coverage command]
    **Result:**
    ```
    [paste actual coverage output]
    ```

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

    ### Traceability Matrix
    | AC ID | Criterion | Test File | Test Function | Status |
    |-------|-----------|-----------|---------------|--------|
    | AC-1 | [criterion text] | [file] | [function] | ✅/❌ |
    | AC-2 | [criterion text] | [file] | [function] | ✅/❌ |

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

    ### VERDICT
    **Coverage:** [X%] vs Threshold [Y%]
    **VERDICT:** PASS / FAIL
    
    If FAIL:
    - **Gap Analysis:** [what needs more tests]
    - **Files needing coverage:** [list with line numbers]

Step 4: Parse QA Analyst Output

Parse agent output:

1. Extract coverage percentage from Coverage Report
2. Extract traceability matrix
3. Extract verdict

testing_state.coverage_actual = [extracted coverage]
testing_state.traceability_matrix = [extracted matrix]
testing_state.tests_written = [count from Test Files Created]

if verdict == "PASS" and coverage_actual >= coverage_threshold:
  → testing_state.verdict = "PASS"
  → Proceed to Step 6

if verdict == "FAIL" or coverage_actual < coverage_threshold:
  → testing_state.verdict = "FAIL"
  → testing_state.iterations += 1
  → if iterations >= max_iterations: Go to Step 7 (Escalate)
  → Go to Step 5 (Dispatch Fix)

Step 5: Dispatch Fix to Implementation Agent

Coverage below threshold → Return to Gate 0 for more tests

Task:
  subagent_type: "[implementation_agent from Gate 0]"  # e.g., "ring:backend-engineer-golang"
  description: "Add tests to meet coverage threshold for [unit_id]"
  prompt: |
    ⛔ COVERAGE BELOW THRESHOLD - Add More Tests

    ## Current Status
    - **Coverage Actual:** [coverage_actual]%
    - **Coverage Threshold:** [coverage_threshold]%
    - **Gap:** [threshold - actual]%
    - **Iteration:** [iterations] of [max_iterations]

    ## Gap Analysis (from QA)
    [paste gap analysis from QA output]

    ## Files Needing Coverage
    [paste files list from QA output]

    ## Requirements
    1. Add tests to cover the identified gaps
    2. Focus on edge cases and error paths
    3. Run coverage after each addition
    4. Stop when coverage >= [threshold]%

    ## Required Output
    - Tests added: [list]
    - New coverage: [X%]
    - Coverage command output

After fix → Go back to Step 3 (Re-dispatch QA Analyst)

Step 6: Prepare Success Output

Generate skill output:

## Testing Summary
**Status:** PASS
**Unit ID:** [unit_id]
**Iterations:** [testing_state.iterations]

## Coverage Report
**Threshold:** [coverage_threshold]%

Gate 4: Fuzz Testing

Dev Fuzz Testing (Gate 4)

Overview

Ensure critical parsing and input handling code has fuzz tests to discover crashes and edge cases through random input generation.

Core principle: Fuzz tests find bugs you didn't think to test for. They're mandatory for all code that handles external input.

CRITICAL: Role Clarification

This skill ORCHESTRATES. QA Analyst Agent (fuzz mode) EXECUTES.

Standards Reference

MANDATORY: Load testing-fuzz.md standards via WebFetch.

Step 1: Validate Input

REQUIRED INPUT:
- unit_id: [task/subtask being tested]
- implementation_files: [files from Gate 0]
- language: [go only for native fuzz]

OPTIONAL INPUT:

Gate 5: Property-Based Testing

Dev Property Testing (Gate 5)

Overview

Ensure domain logic has property-based tests to verify invariants hold for all randomly generated inputs.

Core principle: Property tests verify universal truths about your domain. If "balance is never negative" is a rule, test it with thousands of random inputs.

CRITICAL: Role Clarification

Gate 6: Integration Testing

Dev Integration Testing (Gate 6)

Overview

Ensure every integration scenario has at least one integration test proving real external dependencies work correctly. Use testcontainers for all external services.

Core principle: Unit tests mock dependencies, integration tests verify real behavior. Both are required.

CRITICAL: Role Clarification

This skill ORCHESTRATES. QA Analyst Agent (integration mode) EXECUTES.

Step 0: Detect External Dependencies (Auto-Detection)

MANDATORY: When external_dependencies is empty or not provided, scan the codebase to detect them automatically before validation.

if external_dependencies is empty or not provided:

  detected_dependencies = []

  1. Scan docker-compose.yml / docker-compose.yaml for service images:
     - Grep tool: pattern "postgres" in docker-compose* files → add "postgres"
     - Grep tool: pattern "mongo" in docker-compose* files → add "mongodb"
     - Grep tool: pattern "valkey" in docker-compose* files → add "valkey"
     - Grep tool: pattern "redis" in docker-compose* files → add "redis"
     - Grep tool: pattern "rabbitmq" in docker-compose* files → add "rabbitmq"

  2. Scan dependency manifests:
     if language == "go":
       - Grep tool: pattern "github.com/lib/pq" in go.mod → add "postgres"
       - Grep tool: pattern "github.com/jackc/pgx" in go.mod → add "postgres"
       - Grep tool: pattern "go.mongodb.org/mongo-driver" in go.mod → add "mongodb"
       - Grep tool: pattern "github.com/redis/go-redis" in go.mod → add "redis"
       - Grep tool: pattern "github.com/valkey-io/valkey-go" in go.mod → add "valkey"
       - Grep tool: pattern "github.com/rabbitmq/amqp091-go" in go.mod → add "rabbitmq"

     if language == "typescript":
       - Grep tool: pattern "\"pg\"" in package.json → add "postgres"
       - Grep tool: pattern "@prisma/client" in package.json → add "postgres"
       - Grep tool: pattern "\"mongodb\"" in package.json → add "mongodb"
       - Grep tool: pattern "\"mongoose\"" in package.json → add "mongodb"
       - Grep tool: pattern "\"redis\"" in package.json → add "redis"
       - Grep tool: pattern "\"ioredis\"" in package.json → add "redis"
       - Grep tool: pattern "@valkey" in package.json → add "valkey"
       - Grep tool: pattern "\"amqplib\"" in package.json → add "rabbitmq"
       - Grep tool: pattern "amqp-connection-manager" in package.json → add "rabbitmq"

  3. Deduplicate detected_dependencies
  4. Set external_dependencies = detected_dependencies

  Log: "Auto-detected external dependencies: [detected_dependencies]"

Step 1: Validate Input

REQUIRED INPUT (from ring:dev-cycle orchestrator):
<verify_before_proceed>
- unit_id exists
- language is valid (go|typescript)
</verify_before_proceed>

OPTIONAL INPUT (determines if Gate 6 runs or skips):
- integration_scenarios: [list of scenarios] - if provided and non-empty, Gate 6 runs
- external_dependencies: [list of deps] (from input OR auto-detected in Step 0) - if non-empty, Gate 6 runs
- gate3_handoff: [full Gate 3 output]
- implementation_files: [files from Gate 0]

EXECUTION LOGIC:
1. if any REQUIRED input is missing:
   -> STOP and report: "Missing required input: [field]"
   -> Return to orchestrator with error

2. if integration_scenarios is empty AND external_dependencies is empty (AFTER auto-detection in Step 0):
   -> Gate 6 SKIP (document reason: "No integration scenarios or external dependencies found after codebase scan")
   -> Return skip result with status: "skipped"

3. Otherwise:
   -> Gate 6 REQUIRED - proceed to Step 2

Step 2: Check If Integration Tests Needed

Decision Tree:

1. Task has external_dependencies list (from input or auto-detected)?
   |
   +-- YES -> Gate 6 REQUIRED
   |
   +-- NO -> Continue to #2

2. Task has integration_scenarios?
   |
   +-- YES -> Gate 6 REQUIRED
   |
   +-- NO -> Continue to #3

3. Task acceptance criteria mention "integration", "database", "queue"?
   |
   +-- YES -> Gate 6 REQUIRED
   |
   +-- NO -> Gate 6 SKIP (with reason)

If SKIP:

Return:
  status: SKIP
  skip_reason: "No external dependencies (after codebase scan) or integration scenarios identified"
  ready_for_gate7: YES

Step 3: Initialize Testing State

integration_state = {
  unit_id: [from input],
  scenarios: [from integration_scenarios or derived from external_dependencies],
  dependencies: [from external_dependencies],
  verdict: null,
  iterations: 0,
  max_iterations: 3,
  tests_passed: 0,
  tests_failed: 0,
  flaky_detected: 0
}

Step 4: Dispatch QA Analyst Agent (Integration Mode)

Task:
  subagent_type: "ring:qa-analyst"
  description: "Integration testing for [unit_id]"
  prompt: |
    **test_mode: integration**

    ## Input Context
    - **Unit ID:** [unit_id]
    - **Language:** [language]

    ## Integration Scenarios to Test
    [list integration_scenarios with IS-1, IS-2, etc.]

    ## External Dependencies
    [list external_dependencies with container requirements]

    ## Standards Reference
    WebFetch: https://raw.githubusercontent.com/LerianStudio/ring/main/dev-team/docs/standards/golang/testing-integration.md

    Focus on: All sections, especially INT-5 (Build Tags), INT-6 (Testcontainers), INT-7 (No t.Parallel())

    ## Requirements

    ### File Naming
    - Pattern: `*_integration_test.go`
    - Build tag: `//go:build integration` (MANDATORY at top of file)

    ### Function Naming
    - Pattern: `TestIntegration_{Component}_{Scenario}`
    - Example: `TestIntegration_UserRepository_Create`

    ### Container Usage
    - Use testcontainers for ALL external dependencies
    - Versions MUST match infra/docker-compose
    - Use t.Cleanup() for container termination

    ### Quality Rules
    - No t.Parallel() - integration tests run sequentially
    - No hardcoded ports - use dynamic ports from containers
    - No production services - all deps containerized
    - Each scenario MUST have at least one test

    ## Required Output Format

    ### Test Files Created
    | File | Tests | Lines |
    |------|-------|-------|
    | [path] | [count] | +N |

    ### Scenario Coverage
    | IS ID | Scenario | Test File | Test Function | Status |
    |-------|----------|-----------|---------------|--------|
    | IS-1 | [scenario text] | [file] | [function] | PASS/FAIL |
    | IS-2 | [scenario text] | [file] | [function] | PASS/FAIL |

    ### Quality Gate Results
    | Check | Status | Evidence |
    |-------|--------|----------|
    | Build tags present | PASS/FAIL | [file count] |
    | No hardcoded ports | PASS/FAIL | [grep result] |
    | Testcontainers used | PASS/FAIL | [imports] |
    | No t.Parallel() | PASS/FAIL | [grep result] |
    | Cleanup present | PASS/FAIL | [t.Cleanup count] |

    ### VERDICT
    **Tests:** [X passed, Y failed]
    **Quality Gate:** PASS / FAIL
    **VERDICT:** PASS / FAIL

    If FAIL:
    - **Gap Analysis:** [what needs more tests or fixes]
    - **Files needing attention:** [list with issues]

Step 5: Parse QA Analyst Output

Parse agent output:

1. Extract scenario coverage from Scenario Coverage table
2. Extract quality gate results
3. Extract verdict

integration_state.tests_passed = [count from output]
integration_state.tests_failed = [count from output]

if verdict == "PASS" and quality_gate == "PASS":
  -> integration_state.verdict = "PASS"
  -> Proceed to Step 7 (Success)

if verdict == "FAIL" or quality_gate == "FAIL":
  -> integration_state.verdict = "FAIL"
  -> integration_state.iterations += 1
  -> if iterations >= max_iterations: Go to Step 8 (Escalate)
  -> Go to Step 6 (Dispatch Fix)

Step 6: Dispatch Fix to Implementation Agent

Quality gate failed or tests failing -> Return to implementation agent

Task:
  subagent_type: "[implementation_agent from Gate 0]"

    5. Replace hardcoded ports with dynamic ports

    ## Required Output
    - Issues fixed: [list]
    - Files modified: [list]

After fix -> Go back to Step 4 (Re-dispatch QA Analyst)

Step 7: Prepare Success Output

  1. Scan docker-compose.yml / docker-compose.yaml for service images:
     - Grep tool: pattern "postgres" in docker-compose* files → add "postgres"
     - Grep tool: pattern "mongo" in docker-compose* files → add "mongodb"
     - Grep tool: pattern "valkey" in docker-compose* files → add "valkey"
     - Grep tool: pattern "redis" in docker-compose* files → add "redis"
     - Grep tool: pattern "rabbitmq" in docker-compose* files → add "rabbitmq"

  2. Scan dependency manifests:
     if language == "go":
       - Grep tool: pattern "github.com/lib/pq" in go.mod → add "postgres"
       - Grep tool: pattern "github.com/jackc/pgx" in go.mod → add "postgres"
       - Grep tool: pattern "go.mongodb.org/mongo-driver" in go.mod → add "mongodb"
       - Grep tool: pattern "github.com/redis/go-redis" in go.mod → add "redis"
       - Grep tool: pattern "github.com/valkey-io/valkey-go" in go.mod → add "valkey"
       - Grep tool: pattern "github.com/rabbitmq/amqp091-go" in go.mod → add "rabbitmq"

     if language == "typescript":
       - Grep tool: pattern "\"pg\"" in package.json → add "postgres"
       - Grep tool: pattern "@prisma/client" in package.json → add "postgres"
       - Grep tool: pattern "\"mongodb\"" in package.json → add "mongodb"
       - Grep tool: pattern "\"mongoose\"" in package.json → add "mongodb"
       - Grep tool: pattern "\"redis\"" in package.json → add "redis"
       - Grep tool: pattern "\"ioredis\"" in package.json → add "redis"
       - Grep tool: pattern "@valkey" in package.json → add "valkey"
       - Grep tool: pattern "\"amqplib\"" in package.json → add "rabbitmq"
       - Grep tool: pattern "amqp-connection-manager" in package.json → add "rabbitmq"

  3. Deduplicate detected_dependencies
  4. Set external_dependencies = detected_dependencies

  Log: "Auto-detected external dependencies: [detected_dependencies]"

Step 1: Validate Input

REQUIRED INPUT:
- unit_id: [task/subtask being tested]
- external_dependencies: [postgres, mongodb, valkey, redis, rabbitmq, etc.] (from input OR auto-detected in Step 0)
- language: [go|typescript]

OPTIONAL INPUT:
- gate6_handoff: [full Gate 6 output]

if any REQUIRED input is missing:
  → STOP and report: "Missing required input: [field]"

if external_dependencies is empty (AFTER auto-detection in Step 0):
  → STOP and report: "No external dependencies found after codebase scan - chaos testing requires dependencies"

Step 2: Dispatch QA Analyst Agent (Chaos Mode)

Task tool:
  subagent_type: "ring:qa-analyst"
  model: "opus"
  prompt: |
    **MODE:** CHAOS TESTING (Gate 7)

    **Standards:** Load testing-chaos.md

    **Input:**
    - Unit ID: {unit_id}
    - External Dependencies: {external_dependencies}
    - Language: {language}

    **Requirements:**
    1. Setup Toxiproxy infrastructure in tests/utils/chaos/
    2. Create chaos tests (TestIntegration_Chaos_{Component}_{Scenario} naming)
    3. Use dual-gate pattern (CHAOS=1 env + testing.Short())
    4. Test failure scenarios: Connection Loss, High Latency, Network Partition
    5. Verify 5-phase structure: Normal → Inject → Verify → Restore → Recovery

    **Output Sections Required:**
    - ## Chaos Testing Summary
    - ## Failure Scenarios
    - ## Handoff to Next Gate

Step 3: Evaluate Results

Parse agent output:

if "Status: PASS" in output:
  → Gate 7 PASSED
  → Return success with metrics

if "Status: FAIL" in output:
  → Dispatch fix to implementation agent
  → Re-run chaos tests (max 3 iterations)
  → If still failing: ESCALATE to user

Step 4: Generate Output

## Chaos Testing Summary
**Status:** {PASS|FAIL}
**Dependencies Tested:** {count}
**Scenarios Tested:** {count}
**Recovery Verified:** {Yes|No}

## Failure Scenarios
| Component | Scenario | Status | Recovery |
|-----------|----------|--------|----------|
| {component} | {scenario} | {PASS|FAIL} | {Yes|No} |

## Handoff to Next Gate
- Ready for Gate 8 (Code Review): {YES|NO}
- Iterations: {count}
