I want to automatically test if a piece of software reacts as expected if an essential SQLite DB file fails to be read (causing an I/O error). Exactly that happened some days ago at a client.

Sometimes, I use KDE, and one of the things that I like the most in KDE 4 is the activity concept. At work, it is very useful because I often work on several different projects during one day. Switching to another activity enables me to change the widgets, so that I can have access to folders related to the current project, for instance.
