Sample text

If you decide to add any of these plugins, you’ll find that installation is pretty easy for a logged-in administrator from within SonarQube (see chapter 14 for details). Now we’ll talk about our first couple of plugins: Technical Debt, and Views. 1 Technical debt At the heart of SonarQube is the concept of technical debt: the cumulative cost of work that’s been put off or done poorly enough that it needs to be refactored. Because measuring technical debt is a core principle of SonarQube, it’s not surprising that its creators would come up with a set of technical debt metrics—in dollars and days.

Severities are attached to the rules being checked, not to the issues themselves. So you won’t see SonarQube report one issue of rule A as a Blocker and another issue of rule A as a Minor. There are exceptions. Two rule profiles might include the same rule at different severities, and it’s possible to change the severity of an individual issue. See chapters 10 and 13 for details. NOTE For the sake of discussion, it’s useful to break the issues SonarQube reports into six general categories. They’re listed here in approximate order of importance:  Bugs  Potential bugs  Indications of (potential) programmer error  Things that may lead to future programmer error  Inefficiencies  Style inconsistencies (future productivity obstacles) Very often, issues that represent bugs and potential bugs show up in SonarQube as Blocker or Critical issues.

When those thresholds are crossed in either direction, an Alert is raised (chapter 13 covers setting Alerts). For instance, you may choose to set an Alert when test coverage falls below 80%, or when the number of Blocker-level issues exceeds 0. These rule-based events are what the RSS feed gives you. 3 Seven Axes of Quality The remainder of the widgets on the default dashboard relate to what the creators of SonarQube call the Seven Axes of Quality (and sometimes the Seven Deadly Developer Sins).
