junit4的mock测量带抛出较为service过程实例

serviceImpl方法：
（PS: 我没有写这个方法， 我只是测试）

 @Override
    public boolean returnBookCheck(String userId, String bookId) throws MyException {
        List user = userDao.findUserByIdInRental(userId);
        List book = bookDao.findBookByIdInRental(bookId);
        if (user.size() == 0) {
            throw new MyException("此用户尚未借书");
        }
        if (book.size() == 0) {
            throw new MyException("我还没有借这本书");
        }
        int i = bookDao.deleteBorrowLog(userId, bookId);
        if (i >= 1) {
            int j = bookDao.quantityAdd(bookId);
            return j >= 1;
        }
        return false;
    }
