unittest---ddt+Excel完成参数化

　　前面介绍了几种参数化内容，有ddt，paramunittest，ddt+yaml等例子，今天安静在来介绍一种方法ddt+Excel的方法进行完成数据参数化

读取Excel

安静以前写了一篇通过python读取excel的文章，里面简单的介绍了如何读取excel和写入excel内容。文章地址：python读写Excel方法（xlwt和xlrd）

稳固而执行，可以为师也。一起温习一遍。

这里安静还是那接口来写了，先写个接口需要的参数内容

1、安装xlrd

2、完成表格实例化

3、循环读取表格内容（这里安静把表格的内容分别放到一个列表中）方便后续通过ddt进行读取

import xlrd
def get_data(file_name):
    aa = []
    book = xlrd.open_workbook(file_name)
    sheet = book.sheet_by_index(0)
    for i in range(1, sheet.nrows):
        aa.append(list(sheet.row_values(i, 0, sheet.ncols)))
    return aa
result = get_data('123.xlsx')
print(result)

打印结果：

[['上海', '331eab8f3481f37868378fcdc76cb7cd', '上海'], ['北京', '331eab8f3481f37868378fcdc76cb7cd', '北京'], ['广州', '331eab8f3481f37868378fcdc76cb7c', '错误的请求KEY']]

Ddt+Excel

上面的excel中的数据已经得到了，我们需要把数据和ddt结合在一起，这里安静拿前面的接口进行调试

1、封装接口内容

2、导入unittests模块

3、通过ddt读取excel结果

import ddt
import requests
import unittests

@ddt.ddt
class Test(unittest.TestCase):
    def select(self,city,key):
        url = 'http://apis.juhe.cn/simpleWeather/query'
        data = {
            "city":city,
            "key":key
        }
        r = requests.post(url,data=data)
        return r

    @ddt.data(*result)
    @ddt.unpack
    def test_01(self,city,key,cake):
        result = self.select(city,key)
        print(result.text)
        self.assertIn(cake,result.text)


if __name__ == '__main__':
    unittest.main(verbosity=2)

打印结果：

import xlrd
import unittest
import ddt
import requests

def get_data(file_name):
    aa = []
    book = xlrd.open_workbook(file_name)
    sheet = book.sheet_by_index(0)
    for i in range(1, sheet.nrows):
        aa.append(list(sheet.row_values(i, 0, sheet.ncols)))
    return aa

@ddt.ddt
class Test(unittest.TestCase):
    # 封装接口
    def select(self,city,key):

        data = {
            "city":city,
            "key":key
        }
        r = requests.post(url,data=data)
        return r

    @ddt.data(*result)
    @ddt.unpack
    # 进行参数化
    def test_01(self,city,key,cake):
        result = self.select(city,key)
        print(result.text)
        self.assertIn(cake,result.text)

if __name__ == '__main__':
    # 通过verbosity=2 查看详细内容
    unittest.main(verbosity=2)

本篇主要用到了python读取Excel内容以及ddt的使用方法，学习了这个我们也可以举一反三，通过读取数据库内容，然后在通过ddt的形式进行参数化。
