Postman API Testing: Beginner to Advanced Masterclass

Welcome to the Complete Postman API Testing Masterclass for total beginners, as well as working developers, testers, DevOps engineers, and even technical product managers. When every other aspect of our lives is driven by APIs, learning how to test APIs is a necessary skill for developers, testers, DevOps engineers, as well as technical product managers. This course will get you hands-on, job-finish skills in API testing with Postman — the million-strong industry-standard tool.
No matter if you plan to begin a career in testing, improve development workflows, or incorporate API testing in CI/CD pipelines, this course has a step-by-step learning process with hands-on drills and real-world scenarios.
Course Modules Overview:
Module 1: Introduction to APIs & Postman
Discover what APIs are, why they matter, and how Postman aids in testing. Install Postman and get familiar with the interface. Learn REST, SOAP, and GraphQL fundamentals.
Module 2: HTTP Methods & Requests
Make requests with GET, POST, PUT, DELETE, and PATCH. Understand headers, query/path params, and request bodies with form-data and JSON.
Module 3: API Responses & Status Codes
Learn about HTTP status codes, work with JSON responses, and get data out of real APIs to debug and validate.
Module 4: Collections & Workspaces
Group your APIs into collections, work with many projects, and collaborate with Postman's team workspaces.
Module 5: Variables & Environments
Utilize global, local, and environment variables to create dynamic and reusable requests. Flip between environments such as dev, staging, and prod with ease.
Module 6: Authentication Techniques
Master how to authenticate and test APIs with API keys, bearer tokens, basic auth, and OAuth 1.0/2.0. Securely handle sensitive information.
Module 7: Writing Tests in JavaScript
Script test cases through Postman's JavaScript-based scripting. Test status codes, response times, headers, and data structures.
Module 8: Request Chaining & Automation
Chain API calls together, execute pre-request scripts, and share data across requests for sophisticated simulation of workflow.
Module 9: Collection Runner & Data-Driven Testing
Execute batch tests with the Collection Runner. Import JSON/CSS files to use for data-driven testing and automated test case execution.
Module 10: Postman Monitors & Scheduling
Schedule automated tests using monitors and get notified of failures, uptime, and performance problems.
Module 11: Mock Servers & API Documentation
Want to create Mock APIs with mock servers and auto-generate documentation from a Postman collection to work with your team or stakeholders?
Module 12: CI/CD Integration using Newman
Use Newman, Postman's CLI for testing, to integrate testing into your CI/CD pipeline using Jenkins, GitHub Actions or GitLab.
Module 13: Testing SOAP & GraphQL APIs
Be more than REST — learn how to deal with SOAP services and GraphQL APIs, such as XML/WSDL manipulation and schema queries.
Module 14: Debugging & Troubleshooting
Utilize Postman Console and logs to debug issues, troubleshoot authentication errors, and identify performance issues within your APIs.
Module 15: Getting Started with Performance Testing
Execute simple performance tests, monitor response times, and assess server processing throughput under various loads.
Module 16: Final Capstone Project
Build an end-to-end API testing workflow from the ground up - with requests, scripting, automating, documenting, and CI/CD integration.
By the end of this course, you will be fully prepared to test, automate, and monitor API(s) like a boss - with practical skills that are going to be useful across a wide range of industries.
