What are Software Regressions and How do We Avoid them?

Does your working software sometimes stop working when changes are introduced?

Are your developers unable to impact analyze changes so unwanted side effects get released?

What measures are you taking to reduce the number of software regression errors?

Now, even though it's expensive and doesn't prevent regressions, most companies use system level regression testing.

You could say this is a last resort and in some ways the least effective anti regression measure we can take.

Let's look more closely at what regressions are, why they occur, and which anti regression measures are available to us.

Overview

I want to talk about software regressions and why regressions occur. If software regressions are the enemy, we want to prevent them as well as find them. Now, there are several options and we should consider all of them depending on our circumstances.

This video explores the anti-regression measures at our disposal.
