Abstract

This article examines the role of test architecture restructuring as a condition for the transition to shared quality ownership between QA engineers and developers in an environment of accelerating release cycles and increasing requirements for software system reliability. The study’s relevance stems from the contradiction between the need for high delivery speed and the team’s reliance on monolithic E2E checks that introduce delays, regression fragility, and bottlenecks in the verification process. The aim of the study is to substantiate multi-level test decomposition as a mechanism for redistributing responsibility for quality and increasing engineering resilience. The article’s scientific novelty lies in integrating a technical model of layered test coverage decomposition with an organizational model of QA maturity. It is shown that shifting checks to the component, UI integration, and API levels transforms the structure of team participation in quality assurance. Empirical data indicate a reduction in regression time, decreased flakiness, and the release of labor resources. It is concluded that the architectural restructuring of tests creates a foundation for the Quality Engineering model and consolidates quality as a team-wide practice. The article will be useful for software engineering researchers, QA leads, test architects, developers, and product team managers.
