When it comes to ensuring the quality of your code, SonarQube is a powerful tool that can help you identify and fix issues. But what about new code? How can you ensure that it's also covered by SonarQube?

SonarQube's coverage on new code is a feature that allows you to track the coverage of new code as it's added to your project. This can help you to identify areas where coverage is lacking and to ensure that your code is as complete as possible.

Coverage on new code is important because it can help you to identify and fix issues early on, before they become major problems. By tracking the coverage of your code, you can be sure that you're not missing any areas that could potentially cause issues down the road.

To enable coverage on new code in SonarQube, you need to add the following to your sonar-project.properties file:

sonar.coverage.newCodeOnly=true

Once you've added this property, SonarQube will start tracking the coverage of new code as it's added to your project. You can then view this coverage in the SonarQube dashboard.
