How do I reduce bugs in my code?

How do I reduce bugs in my code?

Here are our 10 best practices you can use to avoid pesky bugs when developing software.

1. Create Testable Code. Make sure you see your test fail at least once.
2. Keep It Simple.
3. Split up Your Code.
4. Don’t Use Comments as a Band-Aid.
5. Take Compiler Warnings Into Account.
6. Test Your Code …
7. Take Your Time.
8. Implement Coding Standards.

How do you find code bugs?

Using the git bisect command, you can perform a binary search through your code base until you find the commit where the bug was introduced. Looking at that diff should give you a fairly small amount of code to dig through. This is a fantastic technique when you are working in a new or unfamiliar code base.

Can you develop a 100 bug free software?

Many techniques exist that allow QA engineers to perform manual or automated testing. Developers can also use unit testing. In a nutshell, a good QA engineer knows how to identify software bugs. However, 100 percent test coverage is impossible as you can’t predict how end users will behave.

Why are there so many bugs per line of code?

Often it is slightly less readable (chaining injects, transformations, and reductions to a collection in one line), but it leaves such a small surface area for bugs to linger.

Why are large codebases are such a problem?

I think in part the reason large codebases are such a problem is that as the code grows, so does the number of existing bugs in the system. The ratio of bugs per lines of code is pretty constant for a project based on the methods the team has followed while adding features and code to the project.

How does refactoring reduce number of bugs per line of code?

A refactoring that doesn’t make the code easier to read (and likely not any more difficult) but delivers the same functionality while reducing the total LOC is a big win. A win in terms of maintainability, it reduces the far too frequent bugs where multiple files/functions need to be ‘kept in sync’ to ensure correct functionality.

Why are there so many bugs in web development?

Going further McConnell talks about the value of defect tracking. As well as the speed of writing quality software in relationship to the defect rate, and bugs related to a team’s software development process maturity. I think McConnell places too high of cost on bugs, at least for modern agile web development.
