Master the essentials of API testing — REST vs GraphQL, status codes, authentication, error handling, and tools. The backbone of modern, reliable backend systems.
Beginner-friendly intro to Postman — the most popular tool for exploring, testing, and automating APIs. Essential for backend QA and modern development.
Master manual API testing — REST principles, HTTP methods, response validation, positive/negative/boundary cases, basic security, Postman workflows, and real-world error handling.
Test the backend first. Status, contracts, and failures that UI tests miss. You own the API checks a pipeline can fail on.
Master the backend automation pyramid: from high-speed API integration tests and consumer-driven contracts (Pact) to database verification (Testcontainers) and security gates. Learn to build reliability systems that prevent microservices outages and scale with cloud-native architectures.
Become the SDET who enables fearless, independent microservices deployments. Master consumer-driven contract testing with Pact, understand why contracts are essential in 2025 microservices era, automate provider verification, integrate with CI/CD gates (can-i-deploy), handle dynamic data with matchers, and build maintainable contract suites that catch incompatibilities early — the critical skill that prevents cascading outages in distributed systems, fintech, e-commerce, and cloud-native architectures.
Master the use of AI to revolutionize API testing in 2025. Learn how to generate realistic, diverse, edge-case-rich payloads with LLMs, validate complex responses against schemas & business rules using AI-assisted checks, create negative scenarios & security payloads, handle dynamic data & versioning, integrate AI generation/validation into CI/CD pipelines, and build maintainable AI-powered API test suites — the cutting-edge skill that dramatically improves coverage, reduces manual effort, and catches subtle bugs in REST, GraphQL, and gRPC APIs.
Master manual performance testing for backend systems — measure key metrics, simulate load, analyze logs, pinpoint bottlenecks, and validate graceful degradation under stress.
