What to Look for in a Regression and CI/CD Testing Partner

• Pipeline-native automation — Tests should trigger automatically on every commit, not run as a separate manual phase.
• Maintainable suites — Ask how the partner keeps tests stable and low-flake as the product changes.
• Fast feedback — Regression results should return in minutes so they don't block delivery.
• Transparent reporting — Look for clear quality gates and trend dashboards that inform go/no-go decisions.
• Scalable team model — Dedicated embedded engineers usually beat one-off project work for continuous testing.

Frequently Asked Questions

What is the difference between regression testing and CI/CD testing?
Regression testing verifies that new changes haven't broken existing functionality. CI/CD testing is about running those tests automatically inside the delivery pipeline on every change. The best companies do both together.

Should regression testing be automated?
Yes. Regression suites grow large and are run repeatedly, so automation is the only way to keep them fast enough to run on every commit.

How do I choose a regression testing company?
Prioritise depth of automation, native CI/CD integration, flake management, and a team model that scales with your release cadence.
