As a developer, it’s easy to fall into the trap of thinking your code is perfect. You spend hours upon hours going over every line of code, and it’s only natural to want to believe that your hard work will pay off. However, you may not realize that bugs can still creep in – no matter how well you think you’ve written your code. DevOps is becoming more relevant, and people are still unaware of what is DevSecOps and its vital role in providing end-to-end security in the industry.
Assuming Code Is Bug-Free
One of the biggest traps developers fall into is assuming their code is bug-free. Just because you didn’t spot any errors while you were writing, it doesn’t mean they’re not there.
To avoid this trap, it’s important to always test your code thoroughly before deploying it. Use a combination of unit tests, integration tests, and manual testing to ensure that all aspects of your code are working as intended. If possible, try to get someone else to review your code as well – another set of eyes can often spot errors that you might have missed.

Additionally, don’t forget to test your code in different environments. Just because it works fine on your local machine doesn’t mean it will work the same way once it’s deployed. Test in as many different scenarios as possible to catch any potential issues.
Not Testing In Different Environments
As mentioned above, it’s important to always test your code in different environments before deploying it. This is especially true for web applications, as so many different browsers and operating systems need to be supported.
To avoid this trap, use a tool like BrowserStack or Sauce Labs to test your code in various browsers and operating systems. This will help ensure that your application works as intended for all users, no matter what browser or OS they’re using.
Don’t forget to test your code on both real devices and emulators/simulators. Real devices can often reveal issues that emulators will miss, so testing on both is essential. Emulators can be useful for quickly testing small changes, but they should never be used as a replacement for real-device testing.
Failing To Properly Document Code
Another trap that developers often fall into is failing to document their code correctly. This can be a problem for two reasons: first, it makes it harder for other developers to understand and work with your code; and second, it makes it more challenging to update and maintain your code over time.
To avoid this trap, always take the time to document your code properly. Write clear and concise comments that explain what each section of code does. If you’re using a version control system like Git, make sure to include detailed commit messages that explain the changes you’re making.
Additionally, consider using a tool like JSDoc or Sphinx to automatically generate documentation for your code. This can help save time in the long run, and it’s a great way to ensure that your documentation is always up-to-date.
Relying On Others’ Code Without Understanding It
One of the most common traps developers fall into is relying on others’ code without understanding it. This can be a problem for two reasons: first, you may not be aware of all the potential security vulnerabilities in the code; and second, you may not be able to fix those vulnerabilities if they’re exploited.
To avoid this trap, always take the time to understand the code you’re using. Read through the code and make sure you understand how it works. If there are any parts that you don’t understand, ask someone for help or look for documentation online.
Additionally, consider third-party auditing code before using it in your own projects. Many tools can help automate this process, such as OWASP Dependency Check or Sonatype Nexus IQ.
Neglecting Security During Development
One of the biggest traps developers fall into is neglecting security during development. This can be a problem because it’s often much harder to add security features to an existing codebase than it is to build them into the code from the start.
To avoid this trap, always keep security in mind when developing your code. Consider using a tool like Brakeman or HPFortify to scan your code for potential vulnerabilities. Additionally, make sure to follow best practices for secure coding, such as avoiding hard-coded passwords and using encryption properly. You can also use a tool like Sqreen to monitor your code for security issues in real-time.
