Why Bugs Appear and Why No Software is Perfect? - rayparker56/softwaretesting GitHub Wiki

Time changes everything, especially technology. With time, bugs can appear in the software. For example, if Apple introduces a new version of the iOS, app developers will have to adjust their product according to the new version so that the application works as expected. These updates help eliminate bugs and ensure that users won’t leave your app.

Updated APIs

The software usually contains APIs for payment integration or social sharing that is updated regularly. These updates may cause bugs to appear that need to be removed to keep users satisfied with the capabilities of your app.

Complex Software

Software becomes more complex with time. The advent of AI, VR, and AR translates into complex solutions that are significantly enhancing customer experiences. A simple and predictable program can be bug-free, however, a constantly-updated software backed by a sophisticated logic is likely to contain bugs.

No Software is Perfect

Zero-bug theory in software testing is a myth that needs to be busted. To stay relevant and fresh, you need to keep your software updated. Dropbox, Gmail, Facebook, Twitter, and other companies constantly try to improve their software to meet evolving user expectations along with changing mobile and web technology.

Execution Environment

While testing, you can push your software to limits as much as you like, however, the execution environment can’t be controlled. End users almost always find the defects given all the various mobile and computer configurations. Therefore, it’s important to offer bug reporting options and customer support.

Physical Limitations

QA engineers can test the product but they can’t predict all possible user actions. Users exhibit different behaviors. By providing users with bug reporting and app rating options, you can always fix bugs and improve your application. Customer feedback is crucial. No applications get an overall 5-star rating on app stores and similarly, no application achieves the number 0 on the defect counter.

The Right Approach to Software Development

First of all, build a plan. Avoid critical issue that may arrive and keep your nerves steady by adopting the following approach:

Expectations and Goals

Aiming for software with no bug is unrealistic and a recipe for disaster. Instead of focusing on a bug-free code, focus on giving your early adopters a product with good functionality that can solve their plans.

Clear Functional Specification

Bugs are caused by a gap in what the software does and what the end-users expect it to do. This problem can be easily solved by creating detailed technical specifications and project requirements before developers start coding.

Quality Above Price

If you are looking for software, let’s say bug management tools, you must always put quality above price. Without a doubt, price is an important factor that can’t be ignored, but would you like to have a software that is cheap and works 50% of the time or software that is a bit expensive but works 90% of the time? I think I know what your answer is. To achieve a frictionless user experience and eliminate bugs, you need a skilled development team and bug management tools that provide necessary assistance to your team. Finding a good team of developers is as hard as finding the right tools. So, don’t rush because the quality of the team reflects on the quality of the application.
