Shift left testing (Paperback)

Paperback. Shift Left Testing: The AI-Driven Journey to Quality - 2026 Edition is a practical guide to building quality into software from the very beginning, combining modern Shift Left principles with automation, exploratory testing, DevOps and the rapidly evolving world of Agentic AI. Testing is changing. The old model of finding defects at the end of development is no longer enough. Written from the perspective of a working Software Test Engineer, this book focuses on one central idea: AI should amplify the tester - not replace the tester. Modern quality engineering requires testers to become involved earlier, collaborate more closely with developers and product teams, understand APIs and architecture, influence testability, automate intelligently and use AI agents to explore software at a scale that was previously impossible. Inside you'll discover how to: Move testing earlier into requirements, design and development. Build quality into the entire software delivery lifecycle. Apply risk-based testing instead of trying to test everything equally. Combine human-led exploratory testing with AI-driven investigation. Use Playwright, Appium, API testing and modern automation effectively. Design AI agents that systematically explore applications. Give AI persistent testing context and memory instead of isolated prompts. Use deterministic test oracles so AI findings can be trusted. Generate meaningful evidence for defects and investigations. Integrate testing into CI/CD pipelines and quality gates. Use Git changes and risk to intelligently target regression testing. Apply Shift Left thinking to security, accessibility, performance and resilience. Control AI context and token usage without sacrificing testing quality. Measure whether your testing strategy is actually improving delivery. Introduce an AI-driven Shift Left model using a practical 30-60-90 day roadmap. The book also explores important 2026 quality engineering practices and standards, including approaches influenced by ISO/IEC/IEEE 29119, ISO/IEC 25010, NIST SSDF, OWASP, WCAG and contemporary DevOps engineering practices. This is not a book about replacing testers with automation. It is about creating a new generation of tester: part investigator, part quality engineer, part automation specialist and increasingly the human test lead directing intelligent AI agents. Whether you are a Software Tester, QA Engineer, Test Automation Engineer, Developer, Engineering Lead or someone beginning the journey into modern quality engineering, this book provides a practical roadmap for moving from late testing, siloed teams and reactive firefighting to early collaboration, continuous testing, AI-assisted exploration and quality built in. Shift Left is no longer simply about testing earlier. In 2026, it is about engineering quality from the very first decision. This item is printed on demand.
