28. Python编写自动化测试用例

接口文档已经提供了，requests库、unittest单元测试框架也已经介绍过，笔者相信读者朋友已经能够独立编写接口自动化测试用例了。可是有一些细节，咱们须要聊一下。好比咱们写登陆接口测试用例，用户名为空、密码为空、用户名错误、密码错误、用户名密码都正确，假设咱们只编写这几条测试用例，咱们通常的作法以下代码所示：

# -*- coding: utf-8 -*-

import requests
import unittest
from nose_parameterized import parameterized


class BlogTest(unittest.TestCase):

    def setUp(self):
        self.url = "http://127.0.0.1:8000/login"
        self.username = 'admin'
        self.password = 'admin111111'

    def tearDown(self):
        pass

    def test_username_null(self):
        """用户名为空"""
        payload = {'username': '', 'password': self.password}
        self.result = requests.post(self.url, payload).json()
        # print(self.result)
        self.assertEqual(self.result['status'], 0)
        self.assertEqual(self.result['message'], 'username or password null')

    def test_password_null(self):
        """密码为空"""
        payload = {'username': self.username, 'password': ''}
        self.result = requests.post(self.url, payload).json()
        # print(self.result)
        self.assertEqual(self.result['status'], 0)
        self.assertEqual(self.result['message'], 'username or password null')

    def test_username_error(self):
        """用户名错误"""
        payload = {'username': 'admin1', 'password': self.password}
        self.result = requests.post(self.url, payload).json()
        # print(self.result)
        self.assertEqual(self.result['status'], 0)
        self.assertEqual(self.result['message'], 'username or password error')

    def test_password_error(self):
        """密码错误"""
        payload = {'username': self.username, 'password': 'admin1111111'}
        self.result = requests.post(self.url, payload).json()
        # print(self.result)
        self.assertEqual(self.result['status'], 0)
        self.assertEqual(self.result['message'], 'username or password error')

    def test_login_success(self):
        """用户名密码正确"""
        payload = {'username': self.username, 'password': self.password}
        self.result = requests.post(self.url, payload).json()
        # print(self.result)
        self.assertEqual(self.result['status'], 1)
        self.assertEqual(self.result['message'], 'login success')


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