This enables developers and stakeholders to identify improvements that could enhance customer experience and functionality.
In addition to testing for functionality, shift left testing also checks that software meets customer requirements. In the process of shift-left testing, teams verify APIs, container configurations, and interactions between microservices, container configurations, and interactions between microservices. Shift left testing helps teams anticipate changes that arise during the development process that can affect performance or other delivery processes. Shift left is the practice of moving testing, quality, and performance evaluation early in the development process, often before any code is written. The concern in production is to maintain software that meets business goals and reliability criteria. When teams release software into production on the right side of the loop, they make the software available to users. The main concern in pre-production on the left side of the loop is building software that meets design criteria. On the left side of the loop, teams plan, develop, and test software in pre-production. To understand shift left and shift right, consider the software development cycle as a continuum, or infinity loop, from left to right.
In DevOps, what is shift left? And what is shift right?
PARADIGM SHIFT DEF VERIFICATION
As part of the continuous cycle of progressive delivery, DevOps teams are also adopting shift left and shift right principles to ensure software quality in these dynamic environments.Īll this shifting may sound abstract, but I’ll explain how this software verification approach benefits DevOps methods and outcomes-and makes software more reliable.
Shift left and shift right are core testing concepts of the agile DevOps methodology, which speeds up application development by releasing small builds frequently as code evolves.
