SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill simplifies the setup and execution of API tests, ensuring your REST and GraphQL endpoints function correctly and efficiently.

Core Features & Use Cases

  • APIRequestContext: Easily make HTTP requests (GET, POST, PUT, DELETE, etc.) to your API endpoints.
  • Schema Validation: Validate API responses against predefined schemas using Zod or AJV for data integrity.
  • Authentication: Implement various authentication patterns like Bearer tokens, API keys, and OAuth2.
  • Error Handling: Test for expected error responses (4xx, 5xx) to ensure robust API behavior.
  • Use Case: You need to test a new user registration endpoint. Use this Skill to send a POST request with user data, validate the successful creation response, and then test error cases like missing required fields or duplicate email addresses.

Quick Start

Use the playwright-api-testing skill to set up Playwright API testing for the '/users' endpoint.

FAQPage Schema
How do I automate API testing for REST and GraphQL endpoints?▼

Automate API testing for REST and GraphQL endpoints using Playwright's APIRequestContext to execute HTTP requests. This approach streamlines sending GET, POST, PUT, and DELETE calls directly to your endpoints for comprehensive validation.

How do I validate API response schemas during testing?▼

Validate API response schemas during testing by applying Zod or AJV schema validation. This ensures your API responses match predefined data structures, maintaining data integrity and catching unexpected payload changes.

Can I test OAuth2 and Bearer token authentication patterns with Playwright?▼

Yes, you can test OAuth2 and Bearer token authentication patterns with Playwright. The framework supports implementing various authentication methods, including API keys, to verify secure access to your protected API endpoints.

What is the best way to test API error handling for 4xx and 5xx responses?▼

The best way to test API error handling for 4xx and 5xx responses is to automate requests that trigger expected error conditions. This verifies your API returns robust error behaviors for scenarios like missing fields or duplicate data.

Does Playwright support mocking API responses and performance testing?▼

Yes, Playwright supports mocking API responses and performance testing. You can simulate specific API behaviors and measure endpoint efficiency directly within your automated API testing workflows.
