I have an API server build using EVE framework. I am using py.test framework for testing. I came across a weird problem.
If I test my APIs using flask's test_client I get unpredictable results. i.e. If I run py.test command 3 times in a row, back to back (without any changes to tests) from the terminal, I get different results e.g.
3 passed, 5 failed
5 passed, 3 failed
8 passed, 0 failed
The tests that fail with 404 for the URL (resource endpoint)
If I use requests library instead of the test_client, everything works correctly, i.e. 8 passed every time I run the tests.
I have a code similar to the following :
client = app.test_client()
# POST_METHOD = client.post
# BASE_URL = '/'
# GET_METHOD = client.get
POST_METHOD = requests.post
BASE_URL = 'http://' + app.config.get('SERVER_NAME') + '/'
GET_METHOD = requests.get
...
...
...
url = BASE_URL + 'resource1'
...
...
r = POST_METHOD(url, data=json.dumps(somedata), headers=headers)
I can consistently reproduce this problem, by simply switching the commented and uncommented code from the top 3 lines, and using test_client instead of requests
I had initially thought that this is something to do with timing (test_client tests running faster than requests) But 404 is baffling.
Why would an endpoint vanish ?

this may be related, but the token is not part of my URL. It is part of the header.
