Python + unittest模块实现多个接口测试

本文知识点

1. 利用unittest模块组织测试多个用例
2. 该方法适用于接口回归测试

代码如下：

import requests
import urllib
import unittest
import sys, io
# 解决console显示乱码的编码问题
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')


class Douban(object):
	"""A class containing interface test method of Douban object"""
	def __init__(self):
		self.host = 'movie.douban.com'
		self.headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0',
		'Referer':'https://movie.douban.com/',
		}

	def get_response(self, url, data):
		resp = requests.post(url=url, data=data, headers=self.headers).content.decode('utf-8')
		return resp

	def test_search_tags_movie(self):
		method = 'search_tags'
		url = 'https://%s/j/%s' % (self.host, method)
		post_data = {
			'type':'movie',
			'source':'index'
		}
		resp = self.get_response(url=url, data=post_data)
		print('executing testcase test_search_tags_movie...')
		return resp
	
	def test_search_tags_hot(self):
		method = 'search_tags'
		url = 'https://%s/j/%s' % (self.host, method)
		post_data = {
			'type': 'movie',
			'tag': urllib.parse.quote('热门')
		}
		resp = self.get_response(url=url, data=post_data)
		print('executing testcase test_search_tags_hot...')
		return resp

	def test_search_tags_tv(self):
		method = 'search_tags'
		url = 'https://%s/j/%s' % (self.host, method)
		post_data = {
			'type':'tv',
			'source':'index'
		}
		resp = self.get_response(url=url, data=post_data)
		print('executing testcase test_search_tags_tv...')
		return resp

class Douban_Testcase(unittest.TestCase):
	"""A class for setting up test and collecting test cases"""
	@classmethod
	def setUpClass(cls):
		cls.douban_obj = Douban()
		
	def setUp(self):
		print('...creating test...')

	def tearDown(self):
		print('...closing test...')

	def test_001(self):
		ret = self.douban_obj.test_search_tags_movie()
		self.assertTrue(ret)

	def test_002(self):
		ret = self.douban_obj.test_search_tags_hot()
		self.assertTrue(ret)

	def test_003(self):
		ret = self.douban_obj.test_search_tags_tv()
		self.assertTrue(ret)

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