When I try to generate test cases for constant file by using Diffblue cover. it shows "No methods found to test: Diffblue Cover was unable to find any methods that can be tested in your selection.". Is there any way to generate test cases for this file?

public class ApiValidationErrorConstants {
    public static final String ACCOUNT_MUST_NOT_BE_NULL = "Account cannot be null";
    public static final String ACCOUNT_CANNOT_BE_NEGATIVE = "Account cannot be negative";
    public static final String APP_MUST_NOT_BE_NULL = "App cannot be null";
    public static final String INTEGRATION_MUST_NOT_BE_NULL = "Integration cannot be null";
    public static final String INTEGRATION_CANNOT_BE_NEGATIVE = "Integration cannot be negative";
}
