Testability: Building Confidence Through Design

This was initially posted in my newsletter BuildItSimple!, if you don’t have a medium membership, you can read it here.

Welcome to the ninth instalment in our series on crucial non-functional requirements (NFRs) in software architecture! After exploring scalability, reliability, availability, maintainability, extensibility, usability, security, and performance, we’re now turning our attention to testability — a critical factor that ensures the quality and reliability of your software system.

Our NFR Journey So Far

Before we dive into testability, let’s quickly recap where we’ve been:

1. Scalability — Servicing all interested parties
2. Reliability — Building Trust in the Digital World
3. Availability — Ensuring Your System is Always There When Users Need It
4. Maintainability — Designing for the Long Haul in Software Architecture
5. Extensibility — Designing for Future Growth in Software Architecture
6. Usability — Architecting for User Satisfaction
7. Security — Architecting the Silent Guardian of Your System
8. Performance — Architecting for Speed and Efficiency
9. Testability — Building…
