The 10 Immutable laws of testing

[Kent Sharkey]

Telerik[^]:

There are 10 laws that drive everything Peter knows about testing. It’s not always pretty (and it’s not always kind) but they are always true.

11. There is always 1 more bug.

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius

Reminds me of Dan Neely's post from earlier this year: [Dan Neely - Professional Profile](https://www.codeproject.com/Members/DanNeely?msg=5857105#xx5857105xx)

Laws are meant to be broken. :laugh:

True. But more of an excuse, rather than a law: There's some (as yet) undefined difference between the test environment and the production environment. This is why testers love containers: What we tested really is what we're running in production.

If only... But to break these we have to either stop adding functionality or stop doing it with code.
