给Python测试类使用自定义的装饰器

在Python自动化测试中,使用自定义的装饰器来给测试方法传递测试数据:
reader.py

import csv
import json

from openpyxl import load_workbook


from setting import DATA_DIR
from os import path

class Reader:
    @classmethod
    def read_excel(cls,xlname, min_row, max_row, min_col, max_col):
        xlname = path.join(DATA_DIR,xlname)
        data = []
        wb = load_workbook(xlname)
        ws = wb.active

        # 将选中区域转换为列表
        ls = list(ws.iter_rows(min_row=min_row, max_row=max_row, min_col=min_col, max_col=max_col))
        wb.save(xlname)

        for row in ls:
            data_row = []
            for col in row:
                data_row.append(col.value)
            data.append(data_row)

        wb.save(xlname)
        return data

    @classmethod
    def read_csv(cls, filename):
        file_name = path.join(DATA_DIR,filename)
        ls  = None
        with open(file=file_name,mode='r',encoding='utf-8') as f:
            ls = list(csv.reader(f))
        return ls

my_decorator.py

def my_decorator(sequeence):
    def outer(func):
        def inner(self):
            for item in sequeence:
                try:
                    func(self,*item)
                except Exception:
                    # print()仅供调试用,后期考虑将出错日志写入数据库
                    print('测试有问题')
                else:# print()仅供调试用,后期考虑将通过日志写入数据库
                    print('测试通过')
        return inner
    return outer
