Python unittest单元测试openpyxl实现过程解析

#首先需要引入单元测试框架
import unittest
#login模块校验规则

    # 正确的用户名和密码

import openpyxl
from openpyxl.worksheet.worksheet import Worksheet
#打开文件
workbook=openpyxl.load_workbook('cases.xlsx')
# print(workbook)

#获取表单名

1）#sheet : Worksheet 可以获取到 对应得表单名字
sheet : Worksheet=workbook['Sheet1']
# print(sheet)
2）#方法二，通过表单名或者排列顺序获得操作表单
sheet=workbook['Sheet1']
#根据位置获取操作表单名称
sheet=workbook.worksheets[0]

#获取数据
1）#根据表单行列获取表单对象,row:行 column：列

cell=sheet.cell(row=2,column=3)

print(cell)
#获取表单数据
print(cell.value)
运行结果：
excel表信息：

#获取表单的最大行数
row_max=sheet.max_row
#获取最大列数
cloumn_max=sheet.max_column

#使用嵌套循环的方式，精准的拿到每一个坐标的对象，然后转化为值
row_data=[]
for row in range(1,row_max+1):
  cloumn_data=[]
  for cloumn in range(1,cloumn_max+1):
    #print(sheet.cell(row,cloumn))
    cloumn_data.append(sheet.cell(row,cloumn).value)
  row_data.append(cloumn_data)
print(row_data)
#运行结果：

#获取第一行表单对象
sheet[1]
#可以与切片一起获取固定行的对象
sheet[1：]


row_data=[]
#获取第一行的所有值
header=[c.value for c in sheet[1]]
for row in range(2,row_max+1):
  cloumn_data=[]
  for cloumn in range(1,cloumn_max+1):
    #print(sheet.cell(row,cloumn))
    cloumn_data.append(sheet.cell(row,cloumn).value)
    #print(cloumn_data)
  #使用zip函数把header与一行一行数据进行 分组并返回 tuple对象，然后使用dict转化为字典
  dict_data=dict(zip(header,cloumn_data))
  row_data.append(dict_data)
print(row_data)
