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)
