testabilityfocused
Testabilityfocused is a software engineering mindset in which testability is treated as a primary design constraint throughout the software development life cycle. It emphasizes building systems that are easy to observe, control, and verify, with the goal of enabling fast, reliable, automated testing from unit tests to end-to-end validation. The term describes both methodology and architectural preferences that prioritize verifiability alongside functionality.
Core principles include clear separation of concerns and modular design, explicit and stable interfaces, determinism, and
Common practices involve designing modules with single responsibility, using small, composable components, and avoiding hidden state.
Benefits include faster feedback, improved reliability, safer refactoring, and clearer documentation of expected behavior through tests.
Challenges include upfront cost and potential overemphasis on testability at the expense of other concerns, possible
Related concepts include test-driven development, behavior-driven development, test automation, and architecture patterns that support testability, such
