While I was away, test automation got a foothold. Looking at it in hindsight, I'm happy I wasn't there to mess it up: great testers favoring the thinking part of testing and speaking up a lot about it are one of the most relevant blockers useful automation has, stopping automation being born while it's still learning its place and form. Lesson learned: give room for things to grow you don't believe in, and they may grow into things you do believe in.
Now that I'm back, and I look at the test automation generated and feel joy on the accomplishment of introducing that there. I did not do it. Or maybe I did, by stepping away and leaving the battle of opinions unbalanced, for the automation side to win. But it is there, it is doing real testing and while it has many many problems, it is a cornerstone of the way we build and release products.
In the 10 years, I've changed. I've come to remember that I was 12 when I wrote my first program. I've come to appreciate internal code quality, and recognize when its lacking. I've stopped looking at testing testers do, and started to look at programming productivity to produce the right quality. I've trained with Llewellyn Falco, a legacy code expert, and re-learned programming legacy code first, test-driven development second and always driven by hands-on work over reading about it.
This week brought me new appreciation in the role of legacy code in what I do now for our test automation system. I'm helping us clean up the mess, without removing the value so that we can add more value. I draw from lessons on legacy code, lessons on (test) product ownership, and intertwine those so that the automation we have would better serve a product line.
I look at this as lifecycle. There's someone to select (or create) the framework. There's someone to use that framework, adding tests to the best abilities they have, doing real useful work. And still, there's the time when the code running the test automation is legacy, still living and breathing, and needing attention to not block us from our future enhancement aspirations.
We're inclined towards a rewrite, while refactor is a better option. When the existing structure emerges from the mess of duplicated details, changing pieces becomes timely. Mending the systems, not making them.
