From February to April 2012 we conducted a survey on the state of testing in Scrum development teams.

The results will be published soon.

One of the questions we asked, and I already want to share with you, was what percentage of the respondents’ test cases / test scenario’s are covered by automated tests.

Only 28% of the respondents automate more than 50% of their cases.

Of course each project has their own peculiarities but in the Agile teams we work with we usually aim to automate more than 50% of the test cases in order for regression testing not to slow down development too much. Choosing the right 50% to automate is critical, and can make or break an automation project.

What percentage of your test cases are covered by automated tests?
