烧瓶单元测试“未能建立新的连接” [英] flask unit test "failed to establish a new connection"
问题描述
$ p
$ b
当通过pytest执行测试时,它会返回这个错误(注意:当基本上使用curl进行测试时,这个方法是有效的):
requests.exceptions.ConnectionError:HTTPConnectionPool(host ='127.0.0.1',
port = 5000):最大重试次数超过url:
/ ctrlm / H_INFOEXPLH:05u3v / output /
(由NewConnectionError引起('< urllib3.connection.HTTPConnection对象
在
0x0486D090>:无法建立新的连接:[WinError 10061]
以下是测试代码:
class RestTests(unittest.TestCase):
测试其余模块。
################# ###########
#### setup and teardown ####
#################### ########
def setUp(self):
在每次测试之前执行
app.config ['TESTING'] = True
app.config ['WTF_CSRF_ENABLED' ] = False
app.config ['DEBUG'] = False
app.config ['THREADED'] = True
self.client = app.test_client()
#事件ID:
self.incident =INC1863137
#ctrl-m作业ID:
self.jobid_noput =server:0ceit
self.jobid_no_job =server:0ceity#作业格式肯定会失败!
def tearDown(self):
在每个测试后的每个testexecuted后执行
pass
###### #########
#### tests ####
###############
def test_ctrl_output(self):
UAT 3:找到ctrl-M作业输出。
response = self.client.post('/ servnow / incident / {}'。 self.incident),
data = json.dumps({'data':这只是一个json测试}),
headers = {'Content-Type':'application / json'}
)
#print(DEBUGGGG !!!!!!!!!!!!!!!!!!! ===============> {}。format(response))
self.assertIsNotNone(response)
也许由setUp()启动的瓶子实例不能被线程化...
在应用程序代码上,这是产生问题的代码:
url =http:// 127。格式(
flask.url_for('joboutput',jobid = jobid))
resp = requests.get(url).json()
嗯,我只是想执行一个查询从一个网址从瓶...
可能,我这样做是错误的方式....
你能帮助我吗?
解决方案Unittest的Flask测试服务器是一种模拟。它不会创建监听套接字。
因此,请求自己是不可能的。
url =http://127.0.0.1:5000 {}.format(
flask.url_for 'joboutput',jobid = jobid))
resp = requests.get(url).json()
将以上述异常结束:
requests.exceptions.ConnectionError:HTTPConnectionPool(host ='127.0.0.1' ,
port = 5000)
无法建立新的连接
socket 127.0 .0.1:5000只是没有创建。
好吧,这也使我认为,如果我无法测试,我正在构建的解决方案是不正确的。
我重建了它。I am writting unit tests for a flask app. This app expose REST endpoints and uses the flask_restful lib.
Basically, one of my endpoints will do requests to other endpoints and do some processing.
While executing the tests through pytest, it returns this error (NOTE: this works when basically testing with curl) :
requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=5000): Max retries exceeded with url: /ctrlm/H_INFOEXPLH:05u3v/output/ (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x0486D090>: Failed to establish a new connection: [WinError 10061]
Here is the test code :
class RestTests(unittest.TestCase): """ Test the rest module. """ ############################ #### setup and teardown #### ############################ def setUp(self): """ Executed prior to each test """ app.config['TESTING'] = True app.config['WTF_CSRF_ENABLED'] = False app.config['DEBUG'] = False app.config['THREADED'] = True self.client = app.test_client() # incident id: self.incident = "INC1863137" # ctrl-m job id : self.jobid_no_output = "server:0ceit" self.jobid_no_job = "server:0ceity" # job format that will surely fail! def tearDown(self): """ executed after each testexecuted after each test """ pass ############### #### tests #### ############### def test_ctrl_output(self): """ UAT 3 : ctrl-M job output is found. """ response = self.client.post('/servnow/incident/{}'.format(self.incident), data=json.dumps({'data': "This is just a json test"}), headers={'Content-Type': 'application/json'} ) #print("DEBUGGGG!!!!!!!!!!!!!!!!!!! ===============> {}".format(response)) self.assertIsNotNone(response)
Well, maybe the flask instance initiated with setUp() is not able to be threaded...
On the app code, this is this code which create the issue :
url = "http://127.0.0.1:5000{}".format( flask.url_for('joboutput', jobid=jobid)) resp = requests.get(url).json()
Well, I just would like to execute a query to an url from flask... Probably, I'm doing it the wrong way....
Could you help me, please?
解决方案Unittest's Flask test server is a kind of a mock. It does not create listening socket.
So, making a request to itself is not possible.
Therefore :
url = "http://127.0.0.1:5000{}".format( flask.url_for('joboutput', jobid=jobid)) resp = requests.get(url).json()
will end in the aforementioned exception :
requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=5000) Failed to establish a new connection
socket 127.0.0.1:5000 is just not created.
Well, it also made me think that the solution i'm building is not right if I cannot test it. I have rebuilded it.
