In computer programming and engineering, debugging is a multi-step process that entails locating a problem, tracking down the source of the problem, and either fixing the problem directly or finding a workaround. Testing the fix or workaround to make sure it functions is the last stage in the debugging process.
When a developer is able to find and reproduce a code error in a computer programme, the debugging process in software development gets started. The software testing process, as well as the full software development lifecycle, includes debugging.
