- Checked for Compliance: Ensuring the product met pre-defined standards.
- Focused on Fault-Finding:
Primarily identifying bugs and errors. - Operated Separately:
Working in isolation from development and operations teams.
DevOps QA: The Collaborative Approach
DevOps introduces a paradigm shift in how QA is perceived and integrated. In this ecosystem, QA becomes a collaborative endeavor, characterized by:
- Shared Responsibility:
Quality is a collective responsibility of developers, QA teams, and operations. - Continuous Involvement: QA is involved throughout the development lifecycle, not just at the end.
- Proactive Problem-Solving: Emphasis on preventing issues rather than just finding them post-development.
Continuous Feedback Loops and Integrated Testing
A critical element of this shift is the establishment of continuous feedback loops and integrated testing:
- Early and Ongoing Testing: QA starts at the beginning of the development cycle and continues throughout.
- Real-Time Feedback:
Developers and QA teams work closely, sharing insights and feedback in real-time. - Automated Testing: Automation tools are used to speed up testing processes and ensure consistency.
The Importance of Early and Frequent Testing
In DevOps, early and frequent testing is crucial for several reasons:
