Ploki is a word used for computer programming development testing. It has no meaning other than its significance as a word with no prior meaning. It therefore is easily found in a code search and thus finds its usefulness in spotting test code before it goes live for any developer who uses this word as their "testing word" while working. The word was picked for its prior meaninglessness, its unique order and combination of letters, and for the convenience of the approximity the letters have to one another on the standard English keyboard.
