Do you ever test your code after it has been deployed to production ? During my first few years programming, I thought this was a bad idea and was told repeatedly told not to test anything in Prod.

After being bitten time and again by environment related problems, I decided to make it a point to perform a smoke test in Prod before handing it to users. Even if it meant a transaction with real money was involved.

Let me take a few moments to recite some of the follies that befell me when I did not test in Prod.

• Code moves to production. We find out that the SSL certificates in QA are installed in a different configuration when compared to Prod. The isSecure() flag on the HttpServletRequest returned a different value because of this and the code bombed.
