Application Validation Test Suite

Run the project's test suite and report results in structured JSON format.

Purpose

Proactively identify issues in the application before they impact users. This command executes the validation stack and reports results for automated processing.

Instructions

  1. Detect Project Type: Look for package.json, pyproject.toml, or other config files
  2. Identify Test Commands: Find the appropriate test runner and commands
  3. Execute Tests in Sequence:
    • Lint check
    • Type check (if applicable)
    • Unit/integration tests
    • Build verification
  4. Capture Results: Record pass/fail status and any error messages
  5. Return JSON: Output only the structured JSON array

Test Execution Sequence

Execute each validation command in order:

  1. Lint Check - Code style and syntax validation
  2. Type Check - Type safety verification (TypeScript, Python with mypy)
  3. Unit Tests - Core functionality tests
  4. Build - Production build verification

IMPORTANT: If a test fails, stop processing and return results thus far.

Output Format

Return ONLY a JSON array with test results:

[
  {
    "test_name": "lint_check",
    "passed": true,
    "execution_command": "npm run lint",
    "test_purpose": "Validates code style and syntax",
    "error": null
  },
  {
    "test_name": "type_check",
    "passed": true,
    "execution_command": "npx tsc --noEmit",
    "test_purpose": "Validates TypeScript types",
    "error": null
  },
  {
    "test_name": "unit_tests",
    "passed": false,
    "execution_command": "npm test",
    "test_purpose": "Validates core functionality",
    "error": "FAIL tests/auth.test.ts - Expected 200, received 401"
  }
]

Result Structure

Each test result includes:

FieldDescription
test_nameIdentifier for the test category
passedBoolean - true if test passed
execution_commandExact command to reproduce
test_purposeWhat this test validates
errorError message if failed, null if passed

Sorting

Sort the JSON array with failed tests (passed: false) at the top.

Integration with Closed Loop

This command is the REQUEST phase of a closed loop:

/test → [JSON results] → /resolve-failed-test {result}

The structured output enables automated resolution.
