Introduction to API Testing

Learn API testing fundamentals including testing types, test pyramid, API test automation benefits, and how API testing fits into modern CI/CD workflows for quality assurance.

Testing Types: Unit, Integration, and E2E

Understand the three testing levels for APIs: unit tests for isolated logic, integration tests for component interaction, and end-to-end tests for full system validation across services.

Postman Basics for API Testing

Get started with Postman for API testing including request building, environment variables, response inspection, collection creation, and the Postman interface overview for efficient testing.

Postman Collections — Complete Guide

Organize API requests into Postman collections with folders, descriptions, and reusable configurations. Learn collection-level variables, authorization, pre-request scripts, and test scripts.

Postman Pre-Request and Test Scripts

Automate API testing with Postman pre-request scripts for setup and test scripts for validation. Learn pm object API, dynamic data generation, chaining requests, and assertion patterns.

Newman CLI for Postman — Complete Guide

Run Postman collections from the command line using Newman. Learn CLI usage, reporters, data files, environment files, HTML reporting, and CI/CD integration for automated API testing.

Supertest for Node.js API Testing

Test Node.js HTTP APIs with Supertest. Learn request building, assertions, authentication, file uploads, cookie handling, and integration with Jest for comprehensive API test suites.

pytest for API Testing with httpx

Test Python APIs with pytest and httpx for async HTTP testing. Learn TestClient, fixtures, parameterization, async tests, and mocking external services for comprehensive API test automation.

API Testing with Python Requests

Test REST APIs using the Python requests library. Learn session management, authentication, file uploads, cookie handling, retry logic, and response validation for programmatic API testing.

REST Assured for Java API Testing

Test Java REST APIs with REST Assured for fluent HTTP testing. Learn given/when/then syntax, JSON/XML validation, authentication, specifications, and integration with JUnit and TestNG.

Contract Testing with Pact — Complete Guide

Implement consumer-driven contract testing with Pact to verify API compatibility between services. Learn Pact flows, provider verification, pact file publishing, and integration with CI/CD pipelines.

Mock Servers for API Testing

Create mock servers for API testing using WireMock (Java) and Pretender (JavaScript). Learn stub mapping, response templating, request matching, stateful mocks, and proxy patterns for isolated testing.

Load Testing APIs with k6

Load test APIs with k6 for performance validation. Learn virtual users, stages and ramping, custom metrics, threshold configuration, HTTP request patterns, and integration with CI/CD pipelines.

Security Testing for APIs — Complete Guide

Test API security including authentication bypass, authorization flaws, injection attacks, rate limiting, CORS misconfiguration, and API key exposure using automated security testing tools.

API Testing Project: Complete Test Suite

Build a comprehensive API test suite integrating unit, integration, contract, security, and load tests into a CI/CD pipeline with reporting, monitoring, and test data management.
