How does sonar Qube work?

SonarQube. SonarQube collects and analyzes source code, measuring quality and providing reports for your projects. The Sonar platform analyzes source code from different aspects and hence it drills down to your code layer by layer, moving from the module level down to the class level.

SonarQube is an open-source platform for continuous inspection of code quality. Using static code analysis, it tries to detect bugs, code smells and security vulnerabilities. Many plugins are available to use it as part of continuous integration pipelines, including for Maven, Jenkins and GitHub.

Additionally, why do we need SonarQube? SonarQube increases productivity by enabling development teams to detect and muzzle duplication and redundancy of code. SonarQube facilitates the team members to reduce the size of application, code complexity, maintenance time and cost and make code easy to read and understand.

Just so, how does SonarQube code coverage work?

SonarQube gets the covered lines from the coverage report given to the analyser. The metric we promote is the Code Coverage because it is the one that reflects the best the portion of source code being covered by unit tests. This is the metric you can see on the home page of a project.

Is SonarQube free to use?

What is SonarQube coverage?

In one sentence Sonar is an open source platform that allows you to track and improve the quality of your source code. One of the key aspects when talking about software quality is the test coverage or code coverage which is how much of your source code is tested by Unit tests.

What are the main components of SonarQube platform?

They are integrated with build tools like Ant, Maven, and Gradle, with CI tools like Jenkins, project management tools like Jira, and a host of other tools that make up the software development toolset.

What does Code Coverage mean?

Code coverage is a measurement of how many lines/blocks/arcs of your code are executed while the automated tests are running. Code coverage is collected by using a specialized tool to instrument the binaries to add tracing calls and run a full set of automated tests against the instrumented product.
