Mike Bland has a new presentation out on software quality:
We’ll discuss why internal software quality matters, why it’s often unappreciated and sacrificed, and what we can do to improve it. More to the point, we’ll discuss the importance of instilling a quality culture to promote the proper mindset first. Only on this foundation will seeking better processes, better tools, better metrics, or AI-generated test cases yield the outcomes we can live with.
Why It Matters
Bland spent the past few years at Apple helping them adopt a culture of testing. He has done the same at Google and the federal government. A robust test suite allowed me and a Google Summer of Code intern to upgrade Lumen Database from Rails 4 to 5 without any hiccups, and I have been a believer ever since.
Automated Testing is a Secret Sauce of Software Engineering
Automated testing serves two functions:
- Forces you to think about and look at your code through a different lens, making it more likely you will spot a bug.
- Prevents the introduction of new bugs by making sure existing functionality does not break with code changes.
It takes effort to learn this tool, but it is a powerful one.
