AC Criteria Validator

Validate acceptance criteria and determine feature completion.

Purpose

Validates that implemented features meet their acceptance criteria, determining when passes can transition from false to true.

Quick Start

from scripts.criteria_validator import CriteriaValidator

validator = CriteriaValidator(project_dir)
result = await validator.validate_feature("auth-001")
print(result.passes)  # True/False
print(result.criteria_results)

Validation Result

{
  "feature_id": "auth-001",
  "passes": true,
  "criteria_results": [
    {
      "criterion": "Valid registration creates user",
      "passed": true,
      "evidence": "test_valid_registration passed",
      "method": "test_execution"
    },
    {
      "criterion": "Invalid email shows error",
      "passed": true,
      "evidence": "test_invalid_email passed",
      "method": "test_execution"
    }
  ],
  "test_summary": {
    "total": 5,
    "passed": 5,
    "failed": 0,
    "coverage": 87.5
  },
  "validated_at": "2024-01-15T10:30:00Z"
}

Validation Methods

Test Execution

  • Run associated test files
  • Check all tests pass
  • Verify coverage threshold
  • Capture test output

Code Analysis

  • Check implementation exists
  • Verify function signatures
  • Validate error handling
  • Check documentation

Manual Criteria

  • UI/UX requirements
  • Performance benchmarks
  • Security requirements
  • Accessibility standards

Validation Rules

validation:
  require_all_tests_pass: true
  minimum_coverage: 80
  require_no_lint_errors: true
  require_type_checks: true

  custom_rules:
    - name: "no_console_logs"
      pattern: "console\\.log"
      severity: "warning"

Workflow

  1. Load: Get feature and criteria
  2. Discover: Find related tests
  3. Execute: Run test suite
  4. Analyze: Check each criterion
  5. Report: Return validation result

State Transition

CRITICAL: passes can ONLY transition false → true

Before validation:
  {"passes": false, "status": "in_progress"}

After successful validation:
  {"passes": true, "status": "completed"}

NEVER:
  {"passes": true} → {"passes": false}

Integration

  • Input: Feature from ac-state-tracker
  • Uses: ac-test-generator test files
  • Output: Validation for state update

API Reference
