Regression Testing: Business-Driven How-To Guide

Every software update comes with risks. A minor code change can break a core feature, and a bug fix can introduce new issues elsewhere. Without proper regression testing, small mistakes can become major problems, — costing time, money, and customer trust.

Manual regression testing can catch these issues, but it’s slow, expensive, and not scalable. That’s where you turn to automation. Then, you need to cover regression automation immediately.

Automated regression testing saves time, reduces costs, and ensures consistent product quality without damaging your development process.

But not all regression testing is the same.

• When should you automate regression testing?
• What testing methods work best?
• How do you select the right tools?

This guide breaks it all down — from key regression testing types to real-world automation strategies — so you can build a faster, more reliable, and cost-effective QA process.

Key takeaways

• Regression testing prevents costly failures. Fixing bugs in production can be up to 100x more expensive than catching them early.
• Automation speeds up testing cycles. Well-implemented automated regression testing…
