Diffblue Cover

Diffblue Cover is an AI testing agent for generating, maintaining and scaling Java unit tests to support regression coverage and legacy modernization. Engineering teams should grant minimal repository access, exclude secrets, review assertions and mocks, run generated tests in CI, measure meaningful coverage and mutation resistance, inspect flaky behavior, and retain developer and release approval.

Begin with authorized, minimal, non-sensitive inputs. Configure access, privacy, retention, visibility, models, citations, quality, disclosure, integration, export, moderation, safety, and spending controls. Compare results with authoritative sources, correct errors and artifacts, test the complete workflow, and retain accountable human approval before publication, calling, customer action, marketing spend, software release, or deployment.

A free Community option or trial is available, while enterprise and team deployments use custom pricing. Repositories, developers, generated tests, CI integrations, deployment, support, security, and contract terms determine cost.

AI output can be inaccurate, speculative, biased, derivative, unsafe, technically flawed, or misleading. Review consent, copyright, likeness, commercial rights, training, retention, renewal, refunds, security, and platform rules. Voice, customer-service, software testing, advertising, jewelry, and business workflows require qualified human review.
