What is Clean Code?

If you’ve followed us for a while, you most likely noticed that we changed the way we describe what we do: from “code quality” to “continuous code inspection,” then “code quality and code security”… to Clean Code.


But what is Clean Code, and what does it encompass?

Cognitive Complexity, Because Testability != Understandability

Cyclomatic Complexity works very well for measuring testability, but not for maintainability. That's why we're introducing Cognitive Complexity, which you'll begin seeing in upcoming versions of our language analyzers.

Roundcube 1.2.2: Command Execution via Email

In this post, we show how a malicious user can remotely execute arbitrary commands on the underlying operating system, simply by writing an email in Roundcube 1.2.2 (>= 1.0). This vulnerability is highly critical because all default installations are affected.

We Are Adjusting Rules Severities

With the release of SonarQube 5.6, we introduced the SonarQube Quality Model, which pulls Bugs and Vulnerabilities out into separate categories to give them the prominence they deserve. Now we're tackling the other half of the job: "sane-itizing" rule severities, because not every bug is Critical.

SonarAnalyzer for C#: The Rule Engine You Want to Use

If you’ve been following the releases of the Scanner for MsBuild and the C# plugin over the last two years, you must have noticed that we significantly improved our integration with the build tool and at the same time added a lot of new rules. Also, we introduced SonarLint for Visual Studio, a new tool to analyze code inside the IDE. With these steps completed we are deprecating the SonarQube ReSharper plugin to be able to provide a consistent, high-level experience among our tools.

Bugs and Vulnerabilities are 1st Class Citizens in SonarQube Quality Model along with Code Smells

In SonarQube 5.5 we adopted an evolved quality model, the SonarQube Quality Model, that takes the best from SQALE and adds what was missing. In doing so, we've highlighted project risks while retaining technical debt.

Why You Shouldn't Use Build Breaker

There have been some heated discussions recently about the Build Breaker plugin... SonarSource doesn't want to continue the feature. The community has come to see it as a must have... So I'd like to explain why at SonarSource we no longer think it should be used.

Analysis of Visual Studio Solutions with the SonarQube Scanner for MSBuild

At the end of April 2015 during the Build Conference, Microsoft and SonarSource Announced SonarQube integration with MSBuild and Team Build. Today, half a year later, we’re releasing the SonarQube Scanner for MSBuild 1.0.2. But what exactly is the SonarQube Scanner for MSBuild? Let’s find out!

Water Leak Changes the Game for Technical Debt Management

A few months ago, at the end of a customer presentation about “The Code Quality Paradigm Change”, I was approached by an attendee who said, “I have been following SonarQube & SonarSource for the last 4-5 years and I am wondering how I could have missed the stuff you just presented. Where do you publish this kind of information?”. I told him that it was all on our blog and wiki and that I would send him the links. Well...

Unit Test Execution in SonarQube

Starting with Java Ecosystem version 2.2 (compatible with SonarQube version 4.2+), we no longer drive the execution of unit tests during Maven analysis. Dropping this feature seemed like such a natural step to us that we were a little surprised when people asked us why we'd taken it.

Three options for pre-commit analysis

As a quality-first focus becomes increasingly important in modern software development, more and more developers are asking how to find new issues before they check their code in. For some of you, it's a point of pride. For others, it's a question of keeping management off your back, and for still others it's simply a matter of not embarrassing yourself publicly. Fortunately, the SonarQube developers (being developers themselves) understand the problem and have come up with three different ways of dealing with it: the Eclipse plugin, the IntelliJ plugin, and the Issues Report plugin.
