Debugging Techniques

Elprocus.com defines “Debugging” as “The important technique to find and remove the number of errors, bugs or defects in a program. It is a multistep process in software development that involves identifying the bug, finding the source of the bug, and correcting the problem to make the program error-free.

In software development, the developer can locate the code error in the program and remove it using this process. Hence, it plays a vital role in the entire software development lifecycle.”

According to Wikipedia, the terms “bug” and “debugging” is popularly attributed to Admiral Grace Hopper in the 1940s. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were “debugging” the system. However, the term “bug”, in the sense of “technical error”, dates back at least, to 1878.”

Debugging plays an important role in the process of creating software, which is to allow developers to follow the implementation of a program step-by-step. Most developers spend more time debugging code than writing code especially working on legacy systems, trying to reproduce bugs, and even going to meetings! Debugging is the biggest time consumer developers have.

Visual Studio gives us a built-in debugger, thanks to which we can place breakpoints at places we have chosen. When it reaches a breakpoint, the program stops running and allows step-by-step running of the remaining lines. Debugging allows us to get into the details of the program and see where exactly the errors occur and what is the reason for this.

Common debugging methods are:

  1. Step debugging
  2. Profiling
  3.  Logs and traces
  4. Error Handling

According to BairesDev, clean code is the foundation of any app. Without it, you risk bugs interfering with the performance and quality of your product — and potentially deterring consumers from using it.

Software development teams put their products through rigorous quality assurance testing to minimize the occurrence of bugs and defects to ensure they’re releasing solid apps to the market.
