Um gerente de teste analisa as métricas de defeitos dos últimos três releases. Os dados mostram que 70% de todos os defeitos reportados vêm do módulo de processamento de pagamento, que representa apenas 15% da base de código. O gerente de teste realoca o esforço de teste para focar mais naquele módulo. Qual princípio de teste melhor justifica essa realocação?

Noos Visual & Functional Recognition
The “Sphere Embrace”: how Noos embraces top contributors without a childish mascot.
In neurobiology, glial cells wrap axons in myelin sheaths to accelerate neural impulses. On Noos, as your explanations earn accelerations and enter the Wiki Synthesis, the Noos Sphere wraps your Identicon with Keplerian orbits and two quantum nodes on its shoulders.
Pure 5×5 geometric Identicon (no personal photo, zero tracking). 1px frame.
Single dashed orbit with 1 bright polar node at the apex. Highlights those who passed the exam.
Two coaxial ellipses (±35°) wrap the avatar with two lateral nodes.
The Sphere Embrace: The Noos Sphere hood wraps the top of the Identicon and rests two luminous nodes on its shoulders.
