Bugs lie in uncertain code

Today after having lunch, I went around articles queue in order to read one or some. As reading the Architecture-Breaking Bugs, a lot of articles I had read before came back to my mind.

The content of article was about flaws in the architecture which the engineers often overlooked, turned out disasters. There was a link to another article which told the story of Airline 5 and has it crashed because only 1 bug at 1 line of code. Going through the articles made me remind of “Clean code” of Uncle Bob, “Don’t Assume It, Prove It” of The Pragmactic Programmer.

Why? Because at the time I was reading the article, I had finished basically a feature in my current project, Migration Process. The process is for migrating old workflow cases into new Process Model Version to avoid too many versions running in parallel. My group was barely finished the process on Friday and had to show it to the Product Owner on next Monday. Honestly, the process was untested, and I was sitting there doing nothing. There were a lot of things to be tested, a lot of scenarios to tests, but I chose to test several of them under the assumption the process will work. HOPE!.

God damn it! I had to go back to do something about it.
