1103_ddt 数据处理

1、传入一个参数

 import unittest
 from ddt import ddt,data,unpack

 @ddt
 class MyTestCase1(unittest.TestCase):
     @data(1,2,3)
     def test_normal(self,value):
         print(value)
         self.assertEqual(value,2)
 if __name__=='__main__':

2、传入元组、字典、列表等复杂结构数据，@data 标签结合 @unpack使用

import unittest
from ddt import ddt,data,unpack

@ddt
class MyTestCase2(unittest.TestCase):
    @data((1,2),(2,3))
    @unpack
    def test_tuple(self,value1,value2):
        print(value1,value2)
        self.assertEqual(value2,value1+1)
    @data([1,2],[2,3])
    @unpack
    def test_list(self,value1,value2):
        print(value1,value2)
        self.assertEqual(value2,value1+1)
    @data({'value1':1,'value2':2},{'value1':1,'value2':2})
    @unpack
    def test_dict(self,value1,value2):
        print(value1,value2)
        self.assertEqual(value2,value1+1)

if __name__=='__main__':

3、以文件作为数据传递@file_data

传递json数据

import unittest
from ddt import ddt,data,unpack,file_data

@ddt
class MyTestCase3(unittest.TestCase):
    @file_data('E:\\a.json')
    def test_file(self,value):
        print(value)

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

以上只是简单的使用了ddt模块进行数据驱动，实际项目应用过程中应该还需要更多知识的结合使用。

这篇文章将ddt模块与xldr excel一起使用，进行数据驱动

自己的写的的

class_011.py

import unittest
from ddt import ddt,data
from API_AUTO.http_requests import HttpRequest
from class_1103.read_me import GetData
from class_1103.gyp1101 import datedd
test_data=datedd('xg.xlsx','python1').get_data()
@ddt
class TestLogin(unittest.TestCase):
    def setUp(self):
        pass
    #正常登录
    @data(*test_data)
    def test_api(self,item):
        res = HttpRequest().http_requests(item['http_method'],item['url'],eval(item['data']),getattr(GetData,'Cookie'))
        if res.cookies: #如果cookie有的话，那么就更新COOKIE
            setattr(GetData,'Cookie',res.cookies)
        try:
            self.assertIn(str(item['expected']),res.json()['code'])
        except AssertionError as e:
            print('登录出错了%s' %e)
            raise
        return res
    def tearDown(self):
        pass
if __name__ == '__main__':
    unittest.main()

class_022.py

import unittest
import HTMLTestRunner
from class_1103.class_011 import TestLogin #具体到类名
from class_1101.gyp1101 import datedd

#存储
suite = unittest.TestSuite()
#加载
loader = unittest.TestLoader()  #ddt不能用创建实力

suite.addTest(loader.loadTestsFromTestCase(TestLogin))
#输出
with open('test_report.html','wb') as file:
    runner = HTMLTestRunner.HTMLTestRunner(stream=file,verbosity=2,title='框架学习练习',tester='GYP测试')
    runner.run(suite)
