Every program or code, even those crafted by the most skilled developer or team, has its own flaws. The software testing process is tied to locating and removing such numerous errors. For simple comprehension, certain errors can be grouped into different types.

Splitting bugs into categories and analyzing each one can be beneficial because it allows one to locate defects more rapidly and with less effort, possibly even assigning different teams for these tasks. Moreover, it might be able to prioritize bug repairs according to their seriousness.

In this article, you will find details about the usual kinds of software errors that professionals deal with and solve on a daily basis.

Severity of Software Bugs

Although software bugs are varied and new problems continue to emerge, quality assurance professionals believe that software testing companies encounter a few common classes every day. All software defects can be classified according to their nature and severity. The severity of the bugs determines the priority for fixing each issue. These defects can be discovered during static or dynamic testing of the software. Static testing allows you to prevent numerous errors; they are cheaper to find and fix at the earliest stage of development. However, dynamic testing allows you to solve more serious problems. 

Here are the levels of impact of bugs on your code, from least to most severe:

  • Low. Bugs of this kind have the smallest impact on your program. These are such trivial issues as grammar errors, wrong colors, slightly inaccurate sizes of objects, etc.
  • Minor. These bugs are not drastic but can interfere with user experience to some extent. UI issues usually fall into this group.
  • High. Certain parts of the program are malfunctioning because of the high impact from the bugs, but overall, it is still usable.
  • Critical. These bugs interfere with the security of your program, which is why experienced testers recommend solving such issues as soon as possible. Key features of the app or program can crash.
  • Block. It is the most severe bug type, as it shuts down the program completely and prevents further testing.

As you can see, there are quite a variety of bugs based on their severity. The most severe defects should be your main priority, although even the smallest bugs have to be fixed too. UI testing, for instance, plays a huge role as well since it facilitates a positive user experience.

Common Software Bugs

While software bugs are so varied and continue to appear every day, there are a few common classes that software testing companies encounter on a regular basis.

Bugs by Type:

  1. Syntax Errors: These bugs occur when the code violates the syntax rules of the programming language, preventing it from being compiled or interpreted correctly.
  2. Runtime Errors: These bugs occur during the execution of the program, causing it to crash or produce unexpected results.
  3. Concurrency Bugs: These bugs occur when multiple threads or processes access shared resources without proper synchronization, leading to race conditions or deadlocks.
  4. Security Bugs: These bugs can lead to vulnerabilities that can be exploited by attackers, such as buffer overflows, SQL injection, or cross-site scripting (XSS) vulnerabilities.
  5. Performance Bugs: These bugs can cause the program to consume excessive computational resources, such as memory, CPU or network bandwidth, leading to slow performance or system crashes.

Bugs Related to Logic:

  1. Incorrect Algorithm Implementation: These bugs occur when the algorithm or logic used to solve a problem is incorrect or inefficient, leading to incorrect results or poor performance.
  2. Off-by-one Errors: As mentioned earlier, these bugs occur when a loop iterates one too many or one too few times, causing incorrect results or unexpected behavior.
  3. Boundary Value Errors: Also mentioned previously, these bugs arise when a program fails to handle edge cases or boundary conditions correctly, leading to unexpected behavior or crashes.
  4. Incorrect Operator Precedence: These bugs occur when the order of operations is not correctly understood or implemented, leading to incorrect results.
  5. Incorrect Control Flow: These bugs occur when the program’s control flow (e.g., if-else statements, loops, function calls) is not implemented correctly, leading to unexpected behavior or incorrect results.

Final Thoughts

It’s worth noting that software bugs are an inevitable part of the development process, but understanding the different types and severity levels can help teams prioritize and deal with them more effectively. From minor cosmetic issues to critical glitches and security vulnerabilities, a wide range of software defects can occur.

By classifying errors based on their nature and impact, teams can allocate appropriate resources, implement targeted testing techniques, and fix the serious problems first to ensure system stability and security.

Ultimately, a systematic approach to identifying, classifying, and resolving various types of software errors is critical to delivering high-quality, reliable, and secure applications to end users.
