Diffblue Cover
AI Testing Agent that autonomously generates, verifies, and fixes enterprise Java unit tests at scale
www.diffblue.com →About
Diffblue Cover is an AI-powered testing agent designed for enterprise Java codebases that autonomously orchestrates the entire unit test generation process — from coverage analysis and test plan creation to parallelized generation, verification, and PR preparation. Unlike general-purpose AI coding assistants, it wraps around your existing enterprise-approved AI stack (such as GitHub Copilot or Claude Code) with a decade of test engineering expertise to guarantee production-ready tests. It supports Java 8 through 25, offers an on-premises/air-gapped deployment option, and uses outcome-based pricing where you only pay for tests that compile and pass. It is built for regulated industries such as financial services, insurance, and defense.
