About

Diffblue Cover analyzes your existing Java program and writes unit regression tests that reflect the current behavior of the code. The CLI tool works 100% autonomously, configuring itself from your Maven or Gradle environment. By bringing automation to the test-writing process, the CLI tool provides a speed boost for organizations that are working towards achieving DevOps goals like CI/CD. Since it fits into a CI pipeline, the CLI tool protects the whole codebase from regressions by shifting testing left. Diffblue Cover's unit regression tests run fast and verify new code changes immediately, helping users detect undesirable changes in the code’s behavior as early as possible, when they're the quickest, easiest, and cheapest to fix. And tests are automatically maintained, saving teams even more time.

About

UI Verify is a visual regression testing service for web interfaces and coding-agent workflows. It captures states from existing Storybook stories, Playwright tests, Vitest browser-mode tests, or custom screenshots, then compares them with approved baselines. Its cloud-rendered reviews label changes as intended, regressions, or flakes and support pull-request checks and comments. Teams can use its CLI in CI and connect coding agents through an MCP server to inspect diffs and review changes. UI Verify can capture only the UI affected by a change. Its free plan includes 10,000 snapshots and 100 AI reviews per month; eligible open-source projects receive 50,000 snapshots per month at no charge.
