Both are related to the fact that most of the testing (with the exception of unit testing) is done by hand.

FORBES: Machiel van der Bijl On Automated Software Testing

Critical parts are typed up by hand and, despite a wealth of testing tools that claim to catch bugs, the complexity of software makes security flaws and errors nearly unavoidable and increasingly common.

FORBES: Saving Software From Itself

Testing new cars behind closed doors by hooking up engines to computer models, on the other hand, ensures that nobody can take any embarrassing pictures.
