/configure:api-tests

Check and configure API contract testing infrastructure for validating API contracts, schemas, and consumer-provider agreements.

When to Use This Skill

Use this skill when...	Use another approach when...
Setting up Pact consumer/provider contract tests	Writing individual unit tests (/configure:tests)
Configuring OpenAPI request/response validation	Validating a single API endpoint manually
Adding JSON Schema or Zod schema testing	Checking general test coverage (/configure:coverage)
Detecting breaking API changes in CI	Reviewing API design decisions (code-review agent)
Auditing API testing compliance across a project	Configuring general CI/CD workflows (/configure:workflows)

Context

• Project root: !pwd
• Package files: !find . -maxdepth 1 \( -name 'package.json' -o -name 'pyproject.toml' \)
• Pact deps: !find . -maxdepth 1 \( -name package.json -o -name pyproject.toml \) -exec grep -l 'pact' {} +
• OpenAPI spec: !find . -maxdepth 1 \( -name 'openapi.yaml' -o -name 'openapi.json' -o -name 'swagger.json' \)
• Pact dir: !find . -maxdepth 1 -type d -name 'pacts'
• Contract tests: !find tests -maxdepth 2 -type d -name 'contract'
• Project standards: !find . -maxdepth 1 -name '.project-standards.yaml'

Parameters

Parse from command arguments:

• --check-only: Report compliance status without modifications (CI/CD mode)
• --fix: Apply fixes automatically without prompting
• --type <pact|openapi|schema>: Focus on specific type

API Testing Types:

Type	Use Case
Pact	Microservices, multiple consumers, breaking change detection
OpenAPI	API-first development, documentation-driven testing
Schema	Simple validation, GraphQL APIs, single service

Execution

Execute this API testing compliance check:

Step 1: Detect existing API testing infrastructure

Check for these indicators:

Indicator	Component	Status
pact in dependencies	Pact contract testing	Installed
openapi.yaml or swagger.json	OpenAPI specification	Present
@apidevtools/swagger-parser	OpenAPI validation	Configured
ajv in dependencies	JSON Schema validation	Configured
pacts/ directory	Pact contracts	Present

Step 2: Analyze current state

For each detected component, check completeness:

Contract Testing (Pact):

• @pact-foundation/pact installed (JS) or pact-python (Python)
• Consumer tests defined
• Provider verification configured
• Pact Broker or PactFlow configured (optional)
• CI/CD pipeline integration

OpenAPI Validation:

• OpenAPI specification file exists
• Request validation middleware configured
• Response validation in tests
• Schema auto-generation configured
• Breaking change detection

Schema Testing:

• JSON Schema definitions exist
• ajv or similar validator installed
• Response validation helpers
• Schema versioning strategy

Step 3: Generate compliance report

Print a formatted compliance report:

API Testing Compliance Report
==============================
Project: [name]
API Type: [REST | GraphQL | gRPC]

Contract Testing (Pact):
  @pact-foundation/pact    package.json               [INSTALLED | MISSING]
  Consumer tests           tests/contract/consumer/   [FOUND | NONE]
  Provider tests           tests/contract/provider/   [FOUND | NONE]
  Pact Broker              CI configuration           [CONFIGURED | OPTIONAL]
  can-i-deploy             CI gate                    [CONFIGURED | OPTIONAL]

OpenAPI Validation:
  OpenAPI spec             openapi.yaml               [EXISTS | MISSING]
  Spec version             OpenAPI 3.1                [CURRENT | OUTDATED]
  Request validation       middleware                 [CONFIGURED | MISSING]
  Response validation      test helpers               [CONFIGURED | MISSING]
  Breaking change CI       oasdiff                    [CONFIGURED | OPTIONAL]

Schema Testing:
  JSON Schemas             schemas/                   [EXISTS | N/A]
  Schema validator         ajv/zod                    [INSTALLED | MISSING]
  Response validation      test helpers               [CONFIGURED | MISSING]

Overall: [X issues found]

Recommendations:
  - Add Pact consumer tests for service dependencies
  - Configure OpenAPI response validation in tests
  - Add breaking change detection to CI

If --check-only, stop here.

Step 4: Configure API testing (if --fix or user confirms)

Apply fixes based on detected project type. Use templates from REFERENCE.md for:

1. Pact Contract Testing - Install dependencies and create consumer/provider test files
2. OpenAPI Validation - Install validator and create test helpers
3. Schema Testing with Zod - Install Zod and create schema definitions
4. Breaking Change Detection - Install oasdiff and add CI check

For JavaScript/TypeScript projects, install with bun add --dev. For Python, install with uv add --group dev.

Step 5: Configure CI/CD integration

Create .github/workflows/api-tests.yml with jobs for:

• Consumer contract tests
• Provider verification (with service containers if needed)
• OpenAPI spec validation
• Breaking change detection on PRs

Add npm/bun scripts to package.json for local testing. Use workflow templates from REFERENCE.md.

Step 6: Update standards tracking

Update .project-standards.yaml:

standards_version: "2025.1"
last_configured: "[timestamp]"
components:
  api_tests: "2025.1"
  api_tests_contract: "[pact|none]"
  api_tests_openapi: true
  api_tests_schema: "[zod|ajv|none]"
  api_tests_breaking_change_ci: true

Step 7: Print final report

Print a summary of all changes applied, scripts added, and next steps for the user to verify the configuration.

For detailed templates and code examples, see REFERENCE.md.

Examples

# Check compliance and offer fixes
/configure:api-tests

# Check only, no modifications
/configure:api-tests --check-only

# Auto-fix all issues
/configure:api-tests --fix

# Configure Pact only
/configure:api-tests --fix --type pact

# Configure OpenAPI validation only
/configure:api-tests --fix --type openapi

Error Handling

• No OpenAPI spec found: Offer to create template
• Pact version mismatch: Suggest upgrade path
• Schema validation fails: Report specific errors
• Pact Broker not configured: Provide setup instructions
