python中unittest框架應(yīng)用詳解
發(fā)布日期：2022-01-03 04:54 | 文章來源：CSDN
1、Unittest為Python內(nèi)嵌的測試框架，不需要特殊配置
2、編寫規(guī)范
需要導(dǎo)入 import unittest
測試類必須繼承unittest.TestCase
測試方法以 test_開頭
模塊和類名沒有要求
TestCase 理解為寫測試用例
TestSuite 理解為測試用例的集合
TestLoader 理解為的測試用例加載
TestRunner 執(zhí)行測試用例，并輸出報告
import unittest
from class_api_login_topup.demo import http_request
from class_api_login_topup.http_attr import Get_Attr # 反射的值 獲取 cookies
# 這是文件http_attr中的Get_Attr類
class Get_Attr:
cookies = None
class Login_Http(unittest.TestCase):
def __init__(self, methodName, url, data, method, expected):
super(Login_Http, self).__init__(methodName) # 超繼承
self.url = url
self.data = data
self.expected = expected
self.method = method
def test_api(self): # 正常登錄
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()
執(zhí)行一：
import unittest
from class_demo_login_topup.http_tools import Login_Http
suite = 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'}]
# 遍歷數(shù)據(jù)，執(zhí)行腳本 addTest 單個執(zhí)行
for item in test_data:
suite.addTest(Login_Http('test_api', item['url'], item['data'], item['method'], item['expected']))
# 執(zhí)行
with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:
runner = unittest.TextTestRunner(stream=file, verbosity=2)
runner.run(suite)
# 運行結(jié)果
{'status': 1, 'code': '10001', 'data': None, 'msg': '登錄成功'}
{'status': 0, 'code': '20111', 'data': None, 'msg': '用戶名或密碼錯誤'}
{'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': '請輸入范圍在0到50萬之間的正數(shù)金額'}
執(zhí)行二：把test_data的數(shù)據(jù)放在EXCEL中運行。
import unittest
from class_demo_login_topup.http_tools import Login_Http
suite = 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)
執(zhí)行三、直接用裝飾器ddt
import unittest
from class_api_login_topup.demo import http_request
from class_api_login_topup.http_attr import Get_Attr # 反射的值
from ddt import ddt, data, unpack
from class_demo_login_topup.http_excel import HttpExcel
test_data = HttpExcel('test_api.xlsx', 'python').real_excel()
@ddt
class Login_Http(unittest.TestCase):
@data(*test_data)
def test_api(self, item): # 正常登錄
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())
執(zhí)行ddt方式一
import unittest
from class_demo_login_topup.http_tools import Login_Http
from class_demo_login_topup.http_excel import HttpExcel
suite = unittest.TestSuite()
loader = unittest.TestLoader()
from class_demo_login_topup import http_tools_1
suite.addTest(loader.loadTestsFromModule(http_tools_1)) # 執(zhí)行整個文件
with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:
runner = unittest.TextTestRunner(stream=file, verbosity=2)
runner.run(suite)
執(zhí)行ddt方式二
import unittest
from class_demo_login_topup.http_tools import Login_Http # 不用ddt的方法
from class_demo_login_topup.http_excel import HttpExcel
suite = 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)) # 執(zhí)行http_tools_1 文件下的Login_Http類，按照類執(zhí)行
with open('http_TestCase.txt', 'w+', encoding='UTF-8') as file:
runner = unittest.TextTestRunner(stream=file, verbosity=2)
runner.run(suite)
