I&#x27;m not a professional Python coder, so maybe I&#x27;m missing things, but I can&#x27;t tell if this is really subtle sarcasm or not:<p>&gt; What they did have was a frightening-looking hodge-podge of cucumber-esque feature tests. I say cucumber-esque because A) It wasn’t cucumber, and B) The feature files weren’t even Gherkin compliant. It was Lettuce. The scourge of Python software testers everywhere!<p>So they had tests, but they weren&#x27;t the tests you like?<p>&gt; What followed was probably the most stressful week of attacks and counter-defense I’ve ever encountered in my career for a few hundred line code change.<p>A &quot;few hundred line code change&quot;?  Could this refactor been split-up over more, smaller changes perhaps?  The last time I was forced to make a change of <i>hundreds</i> of lines, it took days to work-out the justification with all involved.  You&#x27;ll find the effort much more efficient if you are able to split up the code reviews.<p>I stopped there.  I just can&#x27;t tell if he&#x27;s actually serious or not.
