在 OpenStack 中, 針對web應用, 有三種方法來寫單元測試
1) 使用webob生成模擬的request
- from __future__ import print_function
- import webob
- import testtools
-
-
- def hello_world(env, start_response):
- if env['PATH_INFO'] != '/':
- start_response('404 Not Found', [('Content-Type', 'text/plain')])
- return ['Not Found\r\n']
-
- start_response('200 OK', [('Content-Type', 'text/plain')])
- return ['hello world!']
-
- class WsgiAppTestCase(testtools.TestCase):
-
- def test_hello_world_with_webob(self):
- resp = webob.Request.blank('/').get_response(hello_world)
-
- print("resp=%s" % (resp))
-
- self.assertEqual(resp.status_code, 200)
- self.assertEqual(resp.body, "hello world!")
2) 使用webtest生成模擬的request
- from __future__ import print_function
- import httplib2
- import socket
- import webob
- import webtest
- import testtools
-
-
- def hello_world(env, start_response):
- if env['PATH_INFO'] != '/':
- start_response('404 Not Found', [('Content-Type', 'text/plain')])
- return ['Not Found\r\n']
-
- start_response('200 OK', [('Content-Type', 'text/plain')])
- return ['hello world!']
-
-
- class WsgiAppTestCase(testtools.TestCase):
-
- def test_hello_world_with_webtest(self):
- app = webtest.TestApp(hello_world)
- resp = app.get('/')
- print("resp=%s" % (resp))
-
- self.assertEqual(resp.status_code, 200)
- self.assertEqual(resp.body, "hello world!")
3) 啟動一個wsgi server, 並發送真實的 HTTP請求
這種辦法最復雜, 需要以下步驟
- 調用eventlet包, 開啟monkey_patch模式
- 使用eventlet包, 創建一個socket, 並在127.0.0.1:8080上做監聽
- 使用eventlet包, 創建一個wsgi server
- 使用httplib2包, 發送一個HTTP數據包給server
- from __future__ import print_function
- import httplib2
- import socket
- import testtools
-
-
- def hello_world(env, start_response):
- if env['PATH_INFO'] != '/':
- start_response('404 Not Found', [('Content-Type', 'text/plain')])
- return ['Not Found\r\n']
-
- start_response('200 OK', [('Content-Type', 'text/plain')])
- return ['hello world!']
-
-
- class WsgiAppTestCase(testtools.TestCase):
-
- def test_hello_world_with_eventlet(self):
- import eventlet
- eventlet.monkey_patch(os=False)
-
- bind_addr = ("127.0.0.1","8080")
- try:
- info = socket.getaddrinfo(bind_addr[0],
- bind_addr[1],
- socket.AF_UNSPEC,
- socket.SOCK_STREAM)[0]
- family = info[0]
- bind_addr = info[-1]
- except Exception:
- family = socket.AF_INET
-
- sock = eventlet.listen(bind_addr, family)
-
- wsgi_kwargs = {
- 'func': eventlet.wsgi.server,
- 'sock': sock,
- 'site': hello_world,
- 'protocol': eventlet.wsgi.HttpProtocol,
- 'debug': False
- }
-
- server = eventlet.spawn(**wsgi_kwargs)
-
- client = httplib2.Http()
- resp, body = client.request(
- "http://127.0.0.1:8080", "get", headers=None, body=None)
- print("resp=%s, body=%s" % (resp, body))
-
- self.assertEqual(resp.status, 200)
- self.assertEqual(body, "hello world!")
-
- server.kill()
