PayFlow AI-Assisted CI/CD Optimisation & Debugging

Business Scenario

Welcome back to the PayFlow Project.

In the previous lab, you learned how to monitor Jenkins pipelines, generate test reports, track failures, and analyse console logs. As a DevOps QA Engineer, your next responsibility is to use Artificial Intelligence (AI) to improve the efficiency of the CI/CD pipeline.

Pre-Lab Preparation

As your QA Manager, I want you to understand that modern DevOps teams use AI tools to reduce manual effort, identify pipeline issues faster, optimise workflows, and improve test execution. AI can assist in generating pipeline configurations, analysing build failures, suggesting fixes, and optimising automation strategies. In this lab, you will use AI tools to configure Jenkins pipelines, debug CI/CD failures, optimise pipeline workflows, and improve automation test efficiency. By the end of this lab, you will understand how AI enhances DevOps productivity and supports faster, more reliable software delivery.
