/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:

  • Pact Contract Testing - Install dependencies and create consumer/provider test files

  • OpenAPI Validation - Install validator and create test helpers

  • Schema Testing with Zod - Install Zod and create schema definitions

  • 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.

Agentic Optimizations

Context Command

Quick compliance check /configure:api-tests --check-only

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

Pact contracts only /configure:api-tests --fix --type pact

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

Schema testing only /configure:api-tests --fix --type schema

Flags

Flag Description

--check-only

Report status without offering fixes

--fix

Apply all fixes automatically without prompting

--type <type>

Focus on specific type (pact, openapi, schema)

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
