Description
Most API automation frameworks start simple. but become difficult to maintain as projects grow.
Many engineers learn tools, syntax, and frameworks, but struggle when automation projects begin scaling across teams, environments, and business flows. In the AI era, generating code is becoming easier every day. What truly differentiates engineers now is architecture, orchestration, maintainability, and engineering thinking.
This course is designed to teach you how to build scalable API automation frameworks using Java, Rest Assured, and TestNG while focusing on real-world SDET engineering practices.
Instead of only learning how to send requests and validate responses, you will learn how to design reusable automation layers, reduce duplicated logic, centralize configuration, structure scalable frameworks, and build maintainable automation solutions that can evolve with growing projects.
Throughout the course, we will explore both bad and good automation architectures, understand common framework smells, and build a layered API automation framework step by step using practical engineering principles.
In this course, you will learn
• How scalable API automation frameworks are designed
• The difference between endpoint testing and E2E API testing
• How to structure reusable core, domain, and test layers
• How to build reusable API clients and validators
• RequestSpecification and centralized configuration handling
• Payload handling strategies using Maps, DTOs, and Builder patterns
• How to identify and solve architecture smells
• Real-world framework maintainability practices
• How AI can assist automation development while architecture remains the engineer's responsibility
This course is ideal for QA Engineers, SDETs, Automation Engineers, and developers who want to move beyond simple API scripts into professional automation framework engineering.
