Maintainability analysis
Clean code means happier developers
and higher team velocity
SonarQube helps you find your Code Smells and understand what’s wrong.
Then it shows you how to fix the problem.
By some estimates, maintenance accounts for more than 90% of project costs. That’s a lot of time reworking existing code. With clean code you spend less time figuring out how it works and more time having fun writing great code that solves problems!
With clean code you have happier developers and higher team velocity.
By raising new Code Smells early in the process, you're guided to committing only sweet-smelling code. That makes life easier for your colleagues and makes you look like a pro.
Even better, seeing what Code Smells exist in code you're about to tackle gives you advance warning of the pitfalls you'll face and help knowing whom to ask about them.
Add SonarLint to your IDE for the earliest possible feedback. With SonarLint to catch new issues as you code, no one will ever see your mistakes. Plus, it’s free and open source!
Developers own quality in New Code and Pull Request analysis makes it easy to maintain a high standard. Handle issues at the PR stage to clean up the easy stuff before peer review even starts, boosting team velocity and saving time to focus on what’s important: the logic.
Enshrine the team coding standards into your Quality Profile and you'll never argue again about naming conventions or where the curly brace goes. Personal preference gives way to team wisdom, and using SonarQube to enforce the standard short-circuits arguments.
Whether you're new to a language or just polishing your technique, even the most experienced developers don't know everything. That's why SonarQube makes every Issue a teachable moment.
From an issue, you have easy access to the reasoning behind the rule, information on why you should follow it, and what can go wrong if you don't. Plus, most rules have code samples that demonstrate the fix.
Don't change the code because SonarQube says you should. Change it because you've learned to do better.
SonarQube gives you more than just coding rules; a lot of work has gone into collecting and presenting the metrics you need in a way that's easy to understand. In fact, metrics are so important that we invented Cognitive Complexity to fill a gap in the industry standards.
SonarQube raises Cognitive Complexity issues on code that's structured in a way that is hard to understand. Studies show that complex code is more likely to be buggy, and confusing code could lead maintainers to add new Bugs. Use SonarQube as a guide to bring the Cognitive Complexity down and colleague comprehension up.
