【用ddt思想重构项目】Selenium使用xlrd模块读取excel文件、使用pytest参数化实现ddt

前言

一直想学习自动化测试，但是都没行动，业余时间学习零零碎碎并记录20210421。

8、用ddt思想重构项目

• Selenium读取CSV文件
• Selenium读取XML文件
• Selenium读取json文件
• Selenium 读取excel文件
• Selenium读取ini配置文件
• Selenium读取数据库数据
• Selenium参数化测试
• Selenium ddt
• 使用ddt思想重构项目

Selenium使用xlrd模块读取ecel文件

1、调用xlrd：import xlrd
2、使用xlrd模块调用excel表格
3、结合pytest参数化格式处理方式来实现DDT

实例

1、首先创建个excel表格：test.xlsx

2、安装xlrd模块(MAC)：pip3 install xlrd

或者pycharm里选中xlrd，再选择option+O然后选择安装，授权即可

3、openpyxl包的安装，也是用快捷键装

4、代码test_excel.py

import pytest
import xlrd
from openpyxl.workbook import Workbookdef get_data():filename = 'test.xlsx'wb = xlrd.open_workbook(filename)sheet = wb.sheet_by_index(0)rows = sheet.nrowscols = sheet.ncolslst = []for row in range(rows):for col in range(cols):cell_data = sheet.cell_value(row, col)lst.append(cell_data)print(lst)return lst@pytest.mark.parametrize('name', get_data())
def test1(name):print(name)if __name__ == '__main__':pytest.main(['-sv', 'test_excel.py'])

5、运行结果：

报错，需要再安装一个：pip3 install pyexcel-xls

~ % pip3 install pyexcel-xls

再运行看下，正常了
