Software development bugs: how to identify and prevent them

Powerful agile practices such as single tests, code reviews, and appropriate precautions for requirements can prevent or find bugs early on in the application life cycle.

 

No matter how talented the development team is, bugs are inevitable with all software coding work.

 

 

1.  What are the types of bugs that usually occur in each step of the application life cycle?

The life cycle of the application can be divided into five stages: requirements, design, development, testing, and deployment. Various types of bugs may occur in each stage. At the requirement stage, one of the requirements may be "forget" and the product may be incomplete, but bugs at the design stage may not be functioning as intended.

 

At the development stage, there are bugs continuing to be displayed, such as regression bugs accompanying the progress of the project. When implementing a new function and fixing another bug, it is becoming more and more difficult to "break" existing features.

 

 

2. The reason why a simple project is too complicated to manage


As the project grows, not only does the row of the code increase, but the software tends to change over time, so the project is more complicated. Requirements are added and changed, bugs are detected and modified, and customer feedback changes the product to one small function at a time.

 

Another important factor is the number of people working on the product. At the start of the product, only a few people are working, but as the project progresses, more and more developers, QA analysts, and product managers are adopted into the project. As the number of people involved in the same project increases, it is difficult to maintain the original design as it is. Some team members may change jobs with knowledge and expertise or move to another project.

 

As the chord base grows, it is difficult for all team members to comprehend all aspects of the working application, making it difficult to manage which leads to a very complicated project.

 

 

3. What can you do to prevent this?

Communication is an important factor in keeping the product simple. All development teams need to understand the main points of the product and share knowledge between the teams that are working on products.

 

In order to make the result code consistent, it is important to communicate the key points and functions of the main architecture to the entire team.

 

 

4. What can be used to prevent the most common bugs?

Management of requirements is one of the simplest methods of ROI. Write down all requirements, and track them as you go from design to development, testing, and deployment.

 

By minimizing the necessary functions and maintaining the product, you can reduce the amount of unused code and prevent the product from enlarging. Many agile practices work vertically to develop what they need by working vertically and providing value to customers after several weeks. By showing the function of the function to the customer, it is possible to confirm that the developed products meet business needs early on in the development process.

 

Creating a single test is another simple way, not only at the development stage but also has advantages. By creating a single test, you can test the code and prevent bugs in the regulation. But that's not all. In the single test, execute the code one by one at a time, and the developer in charge of the API uses it first to check the API to verify the requirements.

 

 

5. How do you prevent the occurrence of bugs in the first place?

If you are involved in software development that "there is no bug-free software," everyone may have this feeling in one corner of his heart. Most of them are impossible to prevent all bugs, but if necessary, you can reduce the number of bugs by applying single tests, code reviews, and pair programming.

 

Or, as long as the software development method does not change innovation, the practical software cannot contain any bugs. It should not be impossible to reduce bugs to a practical enough level. In fact, if the bugs do not appear at the end of the software, it is the same in practical use.
