谁可以写一下这个工具类DateUtil的单元测试？求大神，要求单测报告不飘红，需要涵盖static方法、异常等

Question

public class DateUtil {
public static Date parseDate(String dateStr, String pattern) {
SimpleDateFormat sdf = new SimpleDateFormat(pattern);
try {
return sdf.parse(dateStr);
} catch (ParseException e) {
// TODO Auto-generated catch block
return null;
}
}

     public static Date getBeforOneDay() {
        SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd");
        Calendar c = Calendar.getInstance();
        try {
            c.add(Calendar.DATE, -1);
            return f.parse(f.format(c.getTime()));
        } catch (ParseException e) {
            e.printStackTrace();
            return null;
        }
    }

}
