Junit怎么对静态代码块进行测试

public class JdbcUtil {    private final static String databaseUrl = "jdbc:mysql://localhost:3306/";    private final static String databaseName = "jdbc";    private final static String databaseUser = "root";    private final static String databasePwd = "root";    private final static String driverName = "com.mysql.jdbc.Driver";    private final static String driverRegex = "/^[A-Za-z](/.)[A-Za-z](/.)[A-Za-z](/.)[A-Za-z]$/";        static {        try {            Pattern p = Pattern.compile(driverRegex);            Matcher m = p.matcher(driverName);            System.out.println("是否匹配" + m.matches());            Class.forName(driverName);        } catch (ClassNotFoundException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
