Analyzing Code Quality with SonarQube

Here's a guide on how to use SonarQube to analyze code quality:

  1. Configure a project:

    • To use SonarQube to analyze your code, you need to create a new project in SonarQube and configure its settings.
    • First, login to SonarQube and click on the "Create New Project" button. Give the project a unique name, and select the language of your project.
    • Next, configure the project's analysis properties. You can specify which code quality checks should be run, which directories to analyze, and more. For example, to analyze a Java project, you can create a file called "sonar-project.properties" in the root directory of your project, and specify the following properties:

bash
Copy code
sonar.projectKey=your-project-key
sonar.projectName=Your Project Name
sonar.projectVersion=1.0

sonar.sources=src
sonar.java.binaries=build

sonar.java.source=11
sonar.java.target=11
sonar.junit.reportPaths=build/test-results/test
  • Run the analysis:

    • Once you've configured your project, you can run the analysis by executing a command in your terminal or build script. For example, to analyze a Java project using the SonarScanner command-line tool, you can run:

    • Copy code
    sonar-scanner
  • This command will analyze your project and upload the results to the SonarQube server.
  • Interpret the results:

    • After the analysis is complete, you can view the results in the SonarQube web interface. The results are presented in various tabs such as "Overview", "Issues", "Coverage", "Duplication", etc.
    • The "Overview" tab provides an overall summary of the analysis, including the number of issues found, the code coverage, and the duplication ratio.
    • The "Issues" tab provides a list of all the issues found in your code, including their severity, location, and a description of the problem. You can use this tab to identify areas of your code that need improvement.
    • The "Coverage" tab provides information about code coverage, including the percentage of lines of code covered by unit tests.
    • The "Duplication" tab provides information about code duplication, including the percentage of code that is duplicated.

    • Here's an example of what an issue might look like in SonarQube:

    vbnet
    Copy code
    Rule: Avoid unused method parameters such as 'arg1'.
File: MyClass.java
Line: 20
Message: Remove the unused method parameter 'arg1'.

    In this example, SonarQube has identified an issue in the "MyClass.java" file on line 20. The issue is that the method parameter "arg1" is unused, and should be removed to improve code quality.
