Why doesn't 0.1+0.2-0.3 equal 0.0 ? This has to do with floating point accuracy and computer's abilities to represent numbers in memory.

Continuous Testing  is defined as a software  testing  type that involves a process of  testing  early,  testing  often,  test  everywhere, and automate. It is a strategy of evaluating quality at every step of the  Continuous  Delivery Process. The goal of  Continuous Testing  is  test  early and  test  often.  Shift Left and Shift Right Pro's and Cons  Pro's LOWER THE COST OF TESTING & DEVELOPMENT It’s well known that the sooner a bug is found, the cheaper it is to fix. One of the aims of Agile testing is detecting errors as soon as possible. With shift-left testing it’s possible to detect in real time, the exact moment in which an error was inserted into the system in order to resolve it in a timely manner. When testing is done with each build (especially during unit testing), the errors that are found are smaller, easier to detect and locate, and subsequently, less costly to ...
