Virheenhakuun, often translated as debugging, is the systematic process of finding and resolving defects or problems within computer programs or systems. This process is crucial for software development, as it ensures that applications function as intended and meet user expectations. Debugging involves identifying the root cause of an error, which can manifest in various ways, such as unexpected behavior, crashes, or incorrect output.

The debugging process typically begins with replicating the reported error. Developers then use various tools and techniques to examine the program's execution flow and data. Common debugging tools include debuggers, which allow developers to step through code line by line, inspect variable values, and set breakpoints. Logging, which records program events and states, is another essential technique for understanding program behavior and pinpointing errors.

When an error is identified, the developer must determine the cause. This might involve analyzing error messages, reviewing code logic, or testing different scenarios. Once the cause is understood, the developer implements a fix, which usually involves modifying the source code. After applying the fix, thorough testing is performed to confirm that the error has been resolved and that no new issues have been introduced. This iterative cycle of identifying, analyzing, fixing, and testing is fundamental to achieving robust and reliable software.
