ROI-based test coverage targets are defined by identifying critical paths and applying risk prioritization across layers like business logic and API. This approach focuses testing on high-value areas rather than chasing 100% coverage, maximizing value per test.

Risk prioritization in pragmatic testing evaluates the balance of risk, cost, and value to guide what to test. It works by creating a priority matrix that ensures essential paths are covered while explicitly deprioritizing low-value tests to minimize wasted effort.

Calculating test ROI for layers like UI, database, API, and business logic involves assessing the value and cost of testing each specific area. This calculation feeds into a coverage matrix that sets layer-specific targets to ensure risk-aware decisions across the stack.

The best way to decide what not to test is by using an explicit "don't test this" guideline based on ROI calculations. This pragmatic testing approach deprioritizes low-risk, high-cost areas, ensuring your quality-assurance strategy minimizes wasted tests while balancing essential coverage.

Yes, a coverage matrix can be applied to prioritize testing across business logic, API endpoints, database, and UI layers. It establishes layer-specific targets that guide risk-aware decisions, ensuring essential paths receive coverage while optimizing overall test ROI.

Chasing 100% test coverage wastes resources on low-value tests. Pragmatic testing uses ROI calculations and risk prioritization to focus on high-value areas, providing explicit "don't test this" guidelines to balance risk, cost, and value rather than maximizing arbitrary metrics.
