-
End-to-end API testing coverage with Postman, curl, Swagger, Supertest, AI, and CI workflows
-
Full lifecycle context combining REST fundamentals, security, automation, GraphQL, and SOAP
-
Hands-on progression from building Express endpoints to reusable checks and continuous testing
Reliable APIs require testing across functionality, data, errors, security, and integration paths. A tester who understands the full lifecycle can investigate behavior manually, automate repeatable checks, and provide fast feedback as services evolve.
The course begins with REST routes, methods, status codes, headers, parameters, JSON, CRUD operations, and client-server data flow. Learners build a simple Express API, document and explore it with Swagger, and test it through Postman, browser tools, and curl. Coverage expands to variables, chained requests, negative paths, data-driven checks, authentication, authorization, validation, rate limiting, and common vulnerabilities. Supertest and JavaScript support reusable automation, while AI-assisted test design and GitHub Actions extend the workflow. GraphQL and SOAP introduce additional service styles.
Practical progression develops the ability to choose meaningful checks, structure suites, manage environments, and examine security-sensitive behavior. Learners connect manual findings to maintainable automation and continuous execution. By the end of this course, you can build, explore, secure, automate, and continuously run API tests across REST, GraphQL, and SOAP workflows.
Suitable for QA engineers, SDETs, API testers, developers, and technical professionals who want broad coverage of manual and automated service testing. It supports learners moving beyond basic Postman use into Express, Swagger, curl, Supertest, security checks, AI-assisted testing, and continuous integration.
