7.读取excel文件

1.读取excel文件

安装xlrd模块，打开cmd，输入pip install xlrd在线安装

import xlrd
class ExcelUtil():
    def __init__(self, excelPath, sheetName):
        self.data = xlrd.open_workbook(excelPath)
        self.table = self.data.sheet_by_name(sheetName)
        # 获取第一行作为key值
        self.keys = self.table.row_values(0)
        # 获取总行数
        self.rowNum = self.table.nrows
        # 获取总列数
        self.colNum = self.table.ncols

    def dict_data(self):
        if self.rowNum <= 1:
            print("总行数小于1")
        else:
            r = []
            j=1
            for i in range(self.rowNum-1):
                s = {}
                # 从第二行取对应values值
                values = self.table.row_values(j)
                for x in range(self.colNum):
                    s[self.keys[x]] = values[x]
                r.append(s)
                j+=1
            return r

if __name__ == "__main__":
    filepath = "du.xlsx"
    sheetName = "Sheet1"
    data = ExcelUtil(filepath, sheetName)
    print (data.dict_data())

2.数据驱动原理

1.测试数据为多个字典的list类型

2.测试类前加修饰@ddt.ddt

3.case前加修饰@ddt.data()

4.运行后用例会自动加载成三个单独的用例

pip install ddt

import ddt
import unittest
testData = [{"username":"花花","psw":"123"},
            {"username": "flower", "psw": "456"},
            {"username": "shadan", "psw": "789"}]

@ddt.ddt
class Test(unittest.TestCase):
    def setUp(self):
        print("start")
    def tearDown(self):
        print("end")

    @ddt.data(*testData)
    def test_ddt(self,data):
        print(data)

if __name__=='__main__':
    unittest.main()
