python中的unittest框架应用详解

本篇内容主要讲解"python中的unittest框架应用详解"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"python中的unittest框架应用详解"吧!

1、Unittest为Python内嵌的测试框架，不需要特殊配置

2、编写规范

需要导入 import unittest

测试类必须继承unittest.TestCase

测试方法以 test_开头

模块和类名没有要求

TestCase 理解为写测试用例

TestSuite 理解为测试用例的集合

TestLoader 理解为的测试用例加载

TestRunner 执行测试用例，并输出报告

import unittestfrom class_api_login_topup.demo import http_requestfrom class_api_login_topup.http_attr import Get_Attr  # 反射的值 获取 cookies# 这是文件http_attr中的Get_Attr类class Get_Attr:    cookies = Noneclass Login_Http(unittest.TestCase):    def __init__(self, methodName, url, data, method, expected):        super(Login_Http, self).__init__(methodName)  # 超继承        self.url = url        self.data = data        self.expected = expected        self.method = method    def test_api(self):  # 正常登录        res = http_request().request(self.url, self.data, self.method, getattr(Get_Attr, 'cookies'))        if res.cookies:            setattr(Get_Attr, 'cookies', res.cookies)        try:            self.assertEqual(self.expected, res.json()['code'])        except AssertionError as e:            print("test_api's, error is {0}", format(e))            raise e        print(res.json())if __name__ == '__main__':    unittest.main()

执行一：

import unittestfrom class_demo_login_topup.http_tools import Login_Httpsuite = unittest.TestSuite()loader = unittest.TestLoader()test_data = [{'url': 'http://test.lemonban.com/futureloan/mvc/api/member/login',              'data': {'mobilephone': 'xxxx', 'pwd': '123456'}, 'expected': '10001', 'method': 'get'},             {'url': 'http://test.lemonban.com/futureloan/mvc/api/member/login',              'data': {'mobilephone': 'xxxx', 'pwd': '12345678'}, 'expected': '20111', 'method': 'get'},             {'url': 'http://test.lemonban.com/futureloan/mvc/api/member/recharge',              'data': {'mobilephone': 'xxxx', 'amount': '1000'}, 'expected': '10001', 'method': 'post'},             {'url': 'http://test.lemonban.com/futureloan/mvc/api/member/recharge',              'data': {'mobilephone': 'xxxx', 'amount': '-100'}, 'expected': '20117', 'method': 'post'}]# 遍历数据，执行脚本 addTest 单个执行for item in test_data:    suite.addTest(Login_Http('test_api', item['url'], item['data'], item['method'], item['expected']))#  执行with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:    runner = unittest.TextTestRunner(stream=file, verbosity=2)    runner.run(suite)# 运行结果{'status': 1, 'code': '10001', 'data': None, 'msg': '登录成功'}{'status': 0, 'code': '20111', 'data': None, 'msg': '用户名或密码错误'}{'status': 1, 'code': '10001', 'data': {'id': 10011655, 'regname': '小蜜蜂', 'pwd': 'E10ADC3949BA59ABBE56E057F20F883E', 'mobilephone': 'xxxx', 'leaveamount': '150000.00', 'type': '1', 'regtime': '2021-07-14 14:54:08.0'}, 'msg': '充值成功'}{'status': 0, 'code': '20117', 'data': None, 'msg': '请输入范围在0到50万之间的正数金额'}

执行二：把test_data的数据放在EXCEL中运行。

import unittestfrom class_demo_login_topup.http_tools import Login_Httpsuite = unittest.TestSuite()loader = unittest.TestLoader()test_data = HttpExcel('test_api.xlsx', 'python').real_excel()for item in test_data:    suite.addTest(Login_Http('test_api', item['url'], eval(item['data']), item['method'], str(item['expected'])))with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:    runner = unittest.TextTestRunner(stream=file, verbosity=2)    runner.run(suite)

执行三、直接用装饰器ddt

import unittestfrom class_api_login_topup.demo import http_requestfrom class_api_login_topup.http_attr import Get_Attr  # 反射的值from ddt import ddt, data, unpackfrom class_demo_login_topup.http_excel import HttpExceltest_data = HttpExcel('test_api.xlsx', 'python').real_excel()@ddtclass Login_Http(unittest.TestCase):    @data(*test_data)    def test_api(self, item):  # 正常登录        res = http_request().request(item['url'], eval(item['data']), item['method'], getattr(Get_Attr, 'cookies'))        if res.cookies:            setattr(Get_Attr, 'cookies', res.cookies)        try:            self.assertEqual(str(item['expected']), res.json()['code'])        except AssertionError as e:            print("test_api's, error is {0}", format(e))            raise e        print(res.json())

执行ddt方式一

import unittestfrom class_demo_login_topup.http_tools import Login_Httpfrom class_demo_login_topup.http_excel import HttpExcelsuite = unittest.TestSuite()loader = unittest.TestLoader()from class_demo_login_topup import http_tools_1suite.addTest(loader.loadTestsFromModule(http_tools_1))  # 执行整个文件with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:    runner = unittest.TextTestRunner(stream=file, verbosity=2)    runner.run(suite)

执行ddt方式二

import unittestfrom class_demo_login_topup.http_tools import Login_Http  # 不用ddt的方法from class_demo_login_topup.http_excel import HttpExcelsuite = unittest.TestSuite()loader = unittest.TestLoader()from class_demo_login_topup.http_tools_1 import * # http_tools_1文件是用ddt的方法suite.addTest(loader.loadTestsFromTestCase(Login_Http))  # 执行http_tools_1 文件下的Login_Http类，按照类执行with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:    runner = unittest.TextTestRunner(stream=file, verbosity=2)    runner.run(suite)
