Does this skill require extra packages for API testing?

No, Playwright includes native API testing capabilities built-in. However, this skill demonstrates how to optionally integrate Ajv for advanced JSON schema validation.

How does the skill handle authentication?

It includes implementation examples for both Bearer token authentication (via headers) and cookie-based authentication for stateful sessions.

Can I test GraphQL APIs with this skill?

Yes, the skill provides specific patterns for executing GraphQL queries and mutations, including how to handle variables and validate the data or errors objects in the response.

Can I use this to mock API responses for my frontend?

Absolutely. It covers using Playwright's page.route feature to intercept network requests, fulfill them with mock data, or simulate server errors and network delays.

安全与测试

Automates REST and GraphQL API validation using Playwright's native testing capabilities and implementation patterns.

关于

This skill empowers developers to build robust API testing suites for both RESTful and GraphQL endpoints using Playwright. It provides standardized patterns for common tasks like handling authentication (Bearer and Cookie-based), mocking API responses for E2E testing, and validating JSON schemas with Ajv. Whether you're performing standalone integration tests or simulating server failures for frontend stability, this skill offers the specific code snippets and configuration guidance needed to ensure backend reliability and contract compliance.
