API Testing and Automation using Playwright
Playwright is a powerful testing framework that extends beyond browser automation to provide comprehensive API testing capabilities. This course teaches developers and testers how to create robust automated API test suites using Playwright with TypeScript. The course covers REST API testing, GraphQL testing, authentication handling, and advanced testing patterns. Through hands-on labs, practical exercises, and real-world examples, participants will learn to build maintainable API test frameworks that ensure reliable backend services and microservices architectures.
Objectives

- Set up and configure Playwright projects for API testing with TypeScript
- Write effective and maintainable API test scripts
- Implement API testing patterns and best practices
- Handle authentication, authorization, and security testing
- Test REST APIs, GraphQL endpoints, and microservices
- Integrate API tests into CI/CD pipelines
- Debug and troubleshoot failing API tests effectively
- Implement data-driven testing and test reporting for APIs
Prerequisites
- Basic understanding of APIs, HTTP protocols, and REST principles
- Experience with backend development or API consumption
- Understanding of software testing concepts and methodologies
