Time for a new take on enterprise testing

TDD and test automation tools such as JUnit, Selenium etc. have been around for such a long time, that you would expect every modern application platform to leverage from test automation by now. But still it amazes me how little proper testing is adopted in the enterprise today. Usually, the test frameworks are in place, but the development teams lacks the discipline to keep coverage up during an extended period of time. I have gotten the feeling that some companies have given up on automated testing, like “we tried TDD and unit tests, but it didn’t work out for us”. Maybe the tools weren’t mature enough, or the organization itself. Maybe getting a buggy software out to market fast, rather than securing its quality was more important for stakeholders at the time. Maybe it was an organizational concern where testing belonged to the test department and the test department only. It’s always easy to afterwards say that something should have been done differently. However, I think there are plenty of reasons to revisit the thought on proper automated enterprise testing. We are half way through 2012 and there are so many amazing test tools and frameworks available that every opportunity exist to make complete and automated test suites, from unit tests to integration tests and acceptance tests.

Unit tests are obviously the most fundamental part. I’ve been writing unit tests so much, that I now have difficulties writing code without tests! For instance, the other day I was reading a book on a for me new JVM language. The book started out with covering basic operations in the language, and I was encouraged to try out the example code in a REPL. One of my first thoughts though was, “alright, but how do I write an equivalent unit test”! Obviously, a REPL is perfect for trying out language features, but in an enterprise context, it is just as natural to try out new code through unit tests. For me, it’s natural that the first context which uses new code is a test context, and I believe it should be for every developer. Testing isn’t something that is separated from development, it’s part of the development process. There are so many reasons why you should have automated testing, that the excuse “we didn’t have time” just don’t cut it.

Hardly no-one disagrees with the fundementals of testing and why you should do it, so lets focus on how to take enterprise testing to the next level instead. I plan to share more of my thoughts on automated enterprise testing in future blog posts, what lies beyond unit tests, what you should test and how you can do it. So keep a close eye on this space!
