What is a bug?

A software bug is a term used to describe an error, mistake, or defect in a computer program that causes accidental results. Buggy systems are not only user-unfriendly but they can result in low customer satisfaction rates. Therefore, every SaaS company should strive to provide bug-free products.

Bugs can cause a wide variety of issues from small formatting changes in the displayed text, to big issues like the program freezing or crashing, loss of valuable data, and even damage to hardware.

There are many types of bugs that can cause different short-term, as well as ongoing issues. Among the most common issues development and testing teams should be familiar with are:

  • Functional errors
  • Syntax errors
  • Logic errors
  • Data type mismatch
  • Security errors
  • Usability errors
  • Performance errors
  • Unit level bugs
  • System-level integration bugs

Bugs in applications can be caused by a variety of factors like miscommunication, unclear requirements, deviation from standards, software complexity, and many more. It is a good practice to periodically generate and analyze bug reports to document issues and avoid them in the future.

Many say that debugging is twice as hard as writing the code itself. To help testing and development teams identify and eliminate bugs, there is a wide variety of debugging tools available. Debugging tools are a type of software that runs and monitors the target program under controlled conditions. This helps identify any changes or deviations that can indicate a malfunction.

It goes without saying that delivering a program that is full of bugs can greatly affect your company’s reputation, worsen customer relationships, and can even lead to customer churn. It’s important to avoid them as much as possible and in case they occur, resolve them in a timely manner within agreed-upon SLAs.

Video description

The video discusses the concept of bugs in computer technology and program code. It explains how bugs can cause malfunctions and mentions bug bounty programs that pay researchers and ethical hackers to find and submit bugs before they become critical. The most common types of bugs are arithmetic, interface, logic, syntax, and teamwork bugs. The video emphasizes the importance of preventing errors in the first place by following a sound development process and testing code early and often. If a bug is found, it needs to be debugged by isolating it, determining the root cause, and fixing the program. Crowdsourcing with bug bounty programs can be an effective method to comb through complex and dense code.
