Tester Day is a professional day for testers, celebrated on September 9th.

History
Behind the legend, on the 9th of September 1947 at Harvard University, that they were testing the Mark II Aiken Relay Calculator, they knew a lepidoptera that he was stuck between the contacts of an electromechanical relay, and Grace Hopper used the word "bug" (from English - "beetle"), what became a newer term that means a computer pardon. The coma was forked and pasted into the technical data sheet with the accompanying inscription: "First actual case of bug being found" ). This is a funny fact, having begun to change the word "bug" from the meaning of "forgiveness". The result of the process revealed that the causes of failure in the robotic computer were named debugging (debugging, “improvement”, literally: bugging). And the name of the profession itself was named after the English word test, to be tested.
