The process of collecting errors in code is termed debugging. Debugging involves identifying and fixing bugs or errors in a program's code. It is a crucial part of software development and often entails using various tools and techniques to track down issues. During debugging, developers not only locate where the errors occur but also understand why they happen and what changes need to be made to eliminate those errors.

In contrast, error tracking typically refers to the ongoing process of monitoring and managing errors that occur in a system during its operation, rather than the initial identification and correction of those errors. Reviewing involves examining code but may not specifically focus on errors; it often pertains to assessing code quality or adherence to standards. Testing is the broader process of executing software to discover any bugs, but it does not necessarily imply that the user is engaged in the systematic process of finding and fixing those errors, which is the essence of debugging.
