Types of software bugs

Every software product contains some bugs. A software bug is system behavior that does not meet the requirements and produces incorrect results. It is impossible to develop a system without errors.

Software product failures can be of various types. Here are some of them.

  • Functional errors: improper system behavior or enabled product features.

  • Communication problems: the user’s communication process with the product may be impossible due to these types of errors, for example, the guide is not available or notifications are not displayed.

  • Missing Commands – Some expected commands are skipped on the system.

  • Syntactic Errors – The grammatical errors or misspelled words and sentences that are used in the product GUI. These errors can be related to the localization procedure.

  • Inappropriate handling of errors: If something goes wrong, the user must receive proper and clear notification. Its text must be brief and must contain all the necessary information about the nature of the error and the ways of its possible elimination.

  • Calculation errors: incorrect logic for the calculation. The shining example of such a mistake is the missing Mars Climate Orbiter. Such a situation happened because English units were used in the metric system.

  • Control flow errors: violation of the sequence of actions.

The errors mentioned above can be detected during different types of software tests, for example functional, system, integration verification, etc. In addition to that, there are several unusual errors that can cause some difficulties during their discovery and correction.

What are unusual software bugs?

  • Heisenbug: errors of this type can modify its properties. These issues are quite difficult to detect as they will never be discovered in the debug mode version of the product.

  • Bohrbug appears under a unique set of conditions. It is sometimes called a ‘ghost’.

  • Mandelbug: the failure of chaotic nature. It is very difficult to define the true reasons for this error. It has very complex causes.

  • Schroedinbug appears due to unusual use of the product.

  • Moon phase error – Rather rare error but causing a lot of problems. It can appear because the system is vulnerable to some failures in a specific period of time and under particular conditions.

  • Statistical error: the typical problem of aggregates. Violates the random production of the particular output.

These bugs are quite serious and the development team should work hard to eliminate the problems. And testers also have to apply different techniques and methodologies to detect most of the serious errors. For example, they use the white box testing technique to better understand the logic of the system.
