The software testing history probably starts with the invention of the word "BUG". Now this word means a discrepancy between the expected and actual behavior within the working software application. In the middle of the XX century one US team faced a problem with their computer (those were huge back then and partly mechanical). It did not work and they could not find a reason why. After some time of analyzing their workhorse they found a small bug that died between the mechanical parts of the computer and resulted those not to work correctly. The report about the incident was written down into the team diary and the body of the bug was attached there as well. That report they called "bug report". Since then the word BUG is used to describe all the glitches that happens with your programs.

Big O notation is used in Computer Science to describe the performance or complexity of an algorithm. Big O specifically describes the worst-case scenario, and can be used to describe the execution time required or the space used (e.g. in memory or on disk) by an algorithm. |
