Abstract

Meta company has many engineering teams working on Meta’s applications codebase. Many teams work specifically on features development for an application, and others work on creating cross-application libraries and frameworks. Besides, specialized teams manage the applications’ release and quality control. This community of engineers creates a fast-changing codebase, which requires continuously checking the applications’ quality at scale. Meta consistently invests in developing a broad set of testing and verification technologies to prevent issues from reaching real users. Sapienz automated testing technology is a crucial component in the company’s testing ecosystem. It guards the applications quality at every stage of the development, from testing builds generated by code changes to testing the final released build. The Sapienz team created specialized testing algorithms for each development stage to maximize its usefulness. Sapienz testing algorithms focus on discovering as many issues as possible early in the development stage. As the stages progress, the focus shifts toward checking features integration and overall application health. Finally, during the application release stage, Sapienz focuses on blocking high-impact crashes before a single real user is affected.
