What are Regression Testing Tools for GitLab?
Regression testing tools are software tools used to detect and fix any functional or technical issues with a program. They are helpful in ensuring that changes to an existing system do not create any unexpected problems. Regression testing tools help find bugs, verify the functionality of a feature, and test for proper integration between components. The primary purpose of regression testing is to ensure that bug fixes work properly, that new features function correctly, and that no new bugs have been introduced with the modification. Regression testing tools can be used for unit tests, end-to-end tests, integration tests, exploratory tests and more.

Checksum.ai
Checksum.ai
Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence. -
