9 Software Design Mistakes Developers Make


Everyone makes mistakes. We all know the feeling of having made a mistake, whether it’s with an assignment at school, an email, or something more important. You can’t avoid making mistakes because that’s how you learn! 

But what about software developers? Most developers are trying to reach perfection in their work. That being said, there are many ways for them to screw up their projects without even realizing it. 

This list covers nine mistakes that developers make which is compiled by Websitesetuper so you can be sure to avoid them when coding your next piece of software.

1. Testing Your Wrong Code

Imagine the following: you’ve finally finished testing your code and it’s time to ship it. You know for sure that it works, right? Wrong. Most software developers, at one point or another, have released software with missing features because they didn’t test enough of the features in their code. This is a big mistake! 

Your code should be tested from top-to-bottom to make sure you haven’t missed anything. If you’re not sure how to test your software, check out this article on black-box testing to learn more!

2. Writing Code That’s Too Complicated

You don’t always have to write super complex code that has twelve different loops to be considered a good programmer. Too much complexity in your code makes it harder to understand, the bug count goes up, and you’ll find yourself wasting hours trying to figure out what’s causing the problem. 

Make sure you don’t overcomplicate things by keeping your variables and functions as simple as possible. You can always break things up into simpler bits if you need to. Simple is better! 

3. Not Breaking Things Up Into Smaller Chunks

One big mistake that developers make is not breaking their project into smaller chunks. You should think of your code as a house: you wouldn’t build a house without first figuring out how to do it in small pieces. The same thing goes for creating and testing your software: don’t try to build and test the whole thing at once! Break it up into manageable-sized chunks and then compile them together. This will help you find bugs before they become embedded in your code.

4. Forgetting About Security

We live in a day and age where cyber attacks and data breaches are at an all-time high. It’s extremely important that you include security measures in your software so you don’t get hacked. Here are some things you can do to ensure your software is secure: 

Add password protection

Use HTTPS protocol for any online access of information (to avoid Man In The Middle Attacks)

Sanitize user input before using it in your code (a good idea is to escape characters and use RegEx whenever possible)…and always, ALWAYS test your website on a real browser to be sure there aren’t any vulnerabilities left unpatched.

5. Not Testing Your Software

Always test your software. When you write software, make sure you go through each possible outcome of it to make sure nothing goes wrong when you release it. Think about how users are going to use your software and account for that in the testing process. Remember, the best way to catch bugs is through thorough testing! 

6. Writing Code That Isn’t Customizable

While having code that’s easy to read is important, you also want code that’s easy to use in different situations. If your code is hard-coded with specific/unpredictable values, then no one can modify or use it without breaking it for everyone else. Make sure your code is as flexible and customizable as possible. This will help you and other developers use and modify it later down the road.

7. Writing Dirty Code

This should be a given, but I’m going to say it anyway: keep your code clean! If you don’t, then you’re going to find yourself wasting time trying to fix bugs that were created by messy code. Make sure you follow this article on how to write clean code so you can improve your programming skills.

8. Not Allowing Others To Use Your Code

What good is writing flexible code if no one can use it? Make sure those who can benefit from using your software are allowed to use it. If you’re worried about them breaking your code by modifying it, then write your code so it’s as stable as possible and only use the bits of it that are necessary.

9. Not Using Organized IDEs Or Editors Instead

Lately, the rise of “test-driven development” has taken over the world of software development. As a result, most new projects are now using some sort of automated testing on their code. But where do you do these tests? You can run them on your computer or on a specialized testing tool like Selenium. Whatever you decide on, make sure you use an IDE (or editor of some sort) to help keep track of everything that needs to be tested.

And if you’re using a programming language like Python, you can even integrate code testing into the language itself. This will ensure that any bugs in your code aren’t overlooked and that you don’t miss any important steps when developing your next project!
