Long used by pilots to prepare an airplane for the every phase of a flight, it serves us in much the same way for code review.
The average suggested time to spend on a code review is between 30 to 60 minutes. So how do you find time to do anything else?
I mention static code analysis tools on a regular basis. It’s an integral part of a well-oiled code review process that ultimately brings value to the product. Let’s do a deep-dive to understand them better, their limitations, and what we can do to get around those limits.
You just finished putting the final touches on the feature you’ve been working on for the last day, and you’re ready to fire off a code review with your colleagues. The next question you may ask yourself is who to include on that list of reviewers. The first instinct is to go with people you’re familiar with, who may be less critical of your code. Unfortunately, that’s not in the code’s best interest, the organization that owns the code, or your own. A code review needs to find defects to bring value. You won’t do that if you don’t involve the best defect finders in your team.
About three months ago I was looking to expand my current playlist of software development podcasts. A quick search came up with a few lists of top development podcasts. There was one that caught my eye, on the Simple Programmer website, that was put together better than the others. I tried a few different podcasts from that list but the one that stuck was from the Simple Programmer himself, John Sonmez. I’d heard John’s name come up on a few other podcasts and had been meaning to check out his YouTube channel and podcast for a while.
An issue that I haven’t seen addressed in depth in is whether you should review every commit to your code base or only aim to cover critical parts of your application. As usual, there isn’t a single answer to the question, and there are advantages (and disadvantages) to both. The answer will often depend on your team’s context, so let’s dive right in to see if we can make some decisions on when to use a certain methodology over another.
There are two major schools of thought when it comes to how best to perform a code review. The first and simplest strategy is to sit down with a colleague, go through the code together, and discuss the finer points of programming. The other, less interactive way, is to use one of many tools available on the market to facilitate the discussion. But what is the best way to maximize value, improve the development skills of your team and promote collaboration? As with most things, the answer is usually somewhere in the middle.
