1. Overview: Why Agile Methodology Is Critical in Software Testing
Modern software delivery is no longer linear. Businesses demand faster releases, continuous feedback, and rapid adaptability, which is why Agile methodology has become the dominant approach. In Agile, testing is not a phase—it is an activity embedded throughout development.
When interviewers ask agile methodology in software testing interview questions and answers, they assess:
- How early and deeply testers are involved
- Collaboration with developers and business stakeholders
- Ability to test continuously under frequent changes
- Understanding of Agile ceremonies, metrics, and quality ownership
This guide is designed for freshers, mid-level testers, senior QA engineers, and leads preparing for Agile-focused interviews in service-based and product companies.
