How Dropbox leverages testing to maintain high level of trust at scale

Dropbox employs various testing strategies to maintain high quality and trust in its Android app, even with a small team. The company transitioned from heavy end-to-end (E2E) testing to more unit tests due to reliability and speed issues. Recently, Dropbox has reinvested in E2E testing, improved test infrastructure, and adopted screenshot testing to prevent visual regressions. They continue to balance their testing pyramid and ensure quality before releasing updates.
