In many domains, critical information is deliberately written down twice in two different places. While this might appear redundant, the practice is a safeguard against errors, loss, and failure. The underlying principle is simple: no single point of failure should be able to compromise the system.

...of course this took longer than anticipated, but I have achieved this milestone, writing and executing a complete functional test in Drupal. It was not an easy, trivial test - and the path I took in implementing it highlights the gotchas and difficulty of writing such tests. As well, my process is likely not be unique, and the challenges I faced appear common. It there appears valuable for me to put down a quick writeup on quirks and tricks I saw along the way. In this article, I assume the reader is an intermediate Drupal developer.

Lost my laptop, possibly due to a virus, and now I have to rebuild it. Yeah, losing a laptop is hard. On the one hand, I have to be ready for such unfortunate events. And I actually am ready - I have a recent backup. I have non-recent backups, as well. Most important things are also duplicated in the cloud. Some heavy files like videos aren't backed up, but I'm actually not losing much there. And I managed to back up text files and important small files of the most recent days, via a tether. So I'm good, overall.
