# Method Annotations

To suppress compiler warnings for test methods written by Diffblue Cover, go to `Diffblue > Change Settings > Method Annotations` and update the `Warnings to suppress` list, as needed. The warnings or warning types defined here will be added to all test methods written by Diffblue Cover (as detailed below) using the `@SuppressWarnings` code annotation. This is especially useful when using SonarQube - see [Using SonarQube with Cover Plugin](/features/cover-plugin/cover-plugin-admin/using-sonarqube-with-cover-plugin.md).
