pytest之公共类封装读取excel（openpyxl）

"""
    封装读取表单测试用例的方法

from openpyxl import load_workbook

        print('self.sheet:',self.sheet,'type(self.sheet)',type(self.sheet))
        #self.sheet:  type(self.sheet) 
        print('生成器self.sheet.values:',self.sheet.values)
        #生成器self.sheet.values: 
        data=list(self.sheet.values)#将生成器转换为列表
        print('将生成器转换为列表data:',data)
        #将生成器转换为列表data: [('姓名', '性别'), ('张三', '男'), ('李四', '女')]
        header=data[0]
        case_data=[]
        for row in data[1:]:
            row_dict=dict(zip(header,row))#将头部和用例打包
            case_data.append(row_dict)
        # print('case_data:',case_data)
        return case_data
#返回的是一个列表，列表中每一条数据都是一个用例

from common.excel_util import MyExcel#导入封装的读取excel

def test_readexcel():
    myexcel=MyExcel('D:\APP\pycharm\pythonProject\huacepyest\data\lest.xlsx','Sheet1')
    # MyExcel.read_data(r'D:\APP\pycharm\pythonProject\huacepyest\data')
    cases = myexcel.read_data()
    print(cases)#[{'姓名': '张三', '性别': '男'}, {'姓名': '李四', '性别': '女'}]

再改进下：

@pytest.mark.parametrize('cases',MyExcel(r'C:\Users\Administrator\PycharmProjects\pythonProject2\data\test.xlsx','Sheet1').read_data())
def test_readexcel(cases):
    # myexcel=MyExcel(r'C:\Users\Administrator\PycharmProjects\pythonProject2\data\test.xlsx','Sheet1').read_data()
    # cases = myexcel.read_data()
    print('姓名',cases['姓名'])
    print('性别',cases['性别'])

执行结果：
