Common Bugs that every developer should know

Introduction

Software bugs are an essential part of software development life cycle. You can not create a perfect code at once. You need to check, analyze, and resolve bugs, anomalies, and errors. Hence, if you want to create a strong software product it requires detailed testing and optimization.

Throughout the entire testing process, teams should remove specific bugs that obstruct the development and testing process. Yet, if you don’t fix the errors in the initial stage, they tend to disrupt the workflow in later stages. If fixed, they become more challenging and time-consuming.

Every developer makes the same mistakes, and they should know what their mistakes are. So that they can provide the best Software QA & Testing Services. In this blog you will learn some very common bugs.

What are software Common bugs?

Software common bugs are an error or flaw in the program that causes crashes in the productions by giving incorrect outputs. There are many reasons behind such mistakes as faulty reasoning, improper syntax, or human error. Moreover, human errors cause the bugs, requiring a significant attention span to spot and debug them.

What is debugging?

It is the process of identifying and removing software bugs that consists in the codes which can crash or later the output. You can say it, Prevent Software Bugs. In addition, debugging lets you learn more about programming in general.

In the entire process of debugging, there are a wide variety of software flaws and faults. Even an expert developer gets stuck in such common bugs or errors and ends up wasting their time. While, a software developer is familiar with types of bugs that encounters frequently and ways for resolving them.

Types Of Common Bugs In Software

Check out some types of Software common bugs and ways to manage them.

Functional Bugs

One of the most common bug Functional bugs means any functionality not working on software

Example:-

If Employee list page design is done with a search box but it’s not implemented from the backend side. so when any user types anything in the search box then nothing will change.

That’s why developers take care of this type of bug because this will affect software quality.

Logical Bugs:-

This type of bug occurs when by mistake somewhere is not given proper value. It’s possible to be in hurry sometimes developers miss to write some code like clearing variable values, assigning default values to variables, Actual parameters which are required, etc.

Example:-

When the user login into the system at that time user’s credentials are stored in the session variable now when the user logged out from the system at that time developer forgot to clear session values then it will become logical bugs.

Workflow Bugs:-

It means every module has some proper workflow and if any developer does not maintain that workflow properly while implementing the module at that time occur workflow bugs.

Example:-

When the user fills any registration form at that time user has two options

• Save
• Save and Exit

Now if the user clicks on “Save and Exit” that time if the system directly moves to the home page without saving the data then it becomes a workflow bug because here workflow is not maintained properly.

Cross Browser Incompatibility:-

Developers just need to take care of this thing that whichever they are developing should work perfectly with all browsers.

Sometimes developer-only tests only one browser like Chrome and due to some dependencies that functionality does not work in the firefox browser.

So that will become a bug when the tester test in another browser.

Syntax Errors:-

Syntax errors mostly come from source code.

While developers were in a hurry, they completed their tasks without following proper syntax when writing the code.

It’s not a big issue, it’s a common mistake, and also at compile time developers are able to see that syntax error so they can resolve it that time.

Example:- Sometimes developers forgot to put semicolons to terminate the statement which causes a syntax error.

Sometimes developer forgot to check datatype that time also give a syntax error.

Missing Static Code Analysis:-

Generally, developers work with local branches and when they finish the task after that they give their code to another team member for code review. if the reviewers forgot to check anywhere to apply static code or not then the Production environment gives some errors caused by static code.

Example:- Developer use localhost for API URL and while they push code for production on that time they forgot to change API URL from localhost to actual URL on that time API will not work.

Responsiveness:-

While we develop any design page at that time must need to take care of this design must be responsive to all devices like Mobile phones, tablets, Monitors, Laptops, etc.

Performance Bugs:-

While some pages give a response after a long time and just spinner spin for too much time it will become performance bugs. While this type of bug occurs developer must optimize the code and find out the reason for taking too much time to give a response.

Example:- When some SQL queries take too much time for execution.

Security Bugs:-

This type of bug occurs while the software does not have any security. This is the most important bug which needs to take care of while we develop any system.

Example:- If the developer forgot to maintain a session for logged-in users and any user pastes the URL directly without logging in to the system then they can use hold software without login.

This will too much affect software quality. This type of bug increases the chances of hacking the system.

Missing Logs:-

Sometimes developers do not maintain proper logs in the system That’s why if any bugs occur they it’s difficult to solve. If the developer maintains a log in the system then it’s easy to find out from which code bug is occurring.

Log means not only for bugs log means every event’s information needs to store as a log like a user registered, Items added in cart, User’s updated profile detail, etc

Conclusion

In the end, if all developers have knowledge about the above points then it helps to maintain software quality.

Also, clarity of above all bugs will help to avoid mistakes in the development process.
