Between 2010–2013, I spoke at a few international software testing conferences (and decided no more, see reasons here). Quite commonly, there were pre-attendance surveys on the attendants’ interested topics. From my memory, the top three (the order might vary) were the same.

• Test Automation (End-to-End)
• Regression Testing
• Web App Testing

However, topics on regression testing were rare at software testing conferences. Several attendants told me this at different events (after attending mine).

In this article, I will share my thoughts and experience in regression testing. This article is a bit long, with the following sections:

• What is Regression Testing?
• Status of Regression Testing in Software Projects (quite sad)
• Regression Testing must be automated, however, …
• Manual Regression Testing is Evil in Agile
