Causes of Occurrence of a Bug in Software Testing

In my previous blog we tried to understand what can be termed as a Bug. Here we will (in continuation to that) try to find out the reasons of causes of generation or occurrence of a Bug.

A Bug shall occur in consequence to:

  • An effort to write a perfect code in terms of performance and/or function
    An effort to embed business requirements in the software
    A complex code structure in place of a simple code structure
    Complex customer requirements
    Repeated code change
    Unclear understanding of business requirements
    Unclear or incomplete customer specifications
    Unclear or incomplete documentation
    Multiple programmers working on the same set of coding over a period of time
    Incompetent programmers working on a code
    Improper coding tool selection
  • And sometimes a bug is passed as it is (uncaught or unhandled) in the final product released to the customer due to improper testing which can have very serious repercussions.

    I will address to this issue in one of my next blogs on how to ensure that the customer gets a total bug free product.
