首先，

引入xlrd模块：

ExcelDDT.py：

import unittest
from time import sleep

from ddt import ddt, data
from selenium import webdriver
from xlrd import open_workbook

def getExcelTestData():
    openExcelFile = open_workbook("./ExcelTestData.xlsx")
    # 打开Excel文件
    getSheet = openExcelFile.sheet_by_name("Sheet1")
    # 获取工作表
    rowNumber = getSheet.nrows
    # 获取行数
    dataList = []
    # 数据List
    for i in range(1, rowNumber):
        # 从第二行开始遍历每一行
        dataList.append(getSheet.row_values(i))
        # 把每个单元格的数值存放到dataList中
    return dataList

@ddt
# ddt驱动
class MyTestCase(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Firefox()
        self.base_url = "https://www.baidu.com/"
        self.driver.get(self.base_url)
        self.driver.maximize_window()
        sleep(2)

    @data(*getExcelTestData())
    # 传递数据
    def test_something(self, data):
        searchTerm, searchResult = tuple(data)
        driver = self.driver
        driver.find_element_by_xpath(".//*[@id='kw']").send_keys(searchTerm)
        driver.find_element_by_xpath(".//*[@id='su']").click()
        sleep(2)
        responseText = driver.find_element_by_xpath(".//*[@id='1']/h3/a").text
        self.assertEqual(responseText, searchResult)

    def tearDown(self):
        self.driver.close()
        self.driver.quit()

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