Testing file upload handlers

[Станислав Соколко]

Hello! I have a pulsar handler which uploads files and want to test it. I can successfully test simple handlers with the help of pulsar.apps.wsgi.test_wsgi_environ and pulsar.apps.wsgi.WsgiRequest. The tricky thing in testing file upload handlers is that I want to genetate a test body of the request to give it to test_wsgi_environ method as body param. The body needs to be a file-like stream containing data encoded using multipart/form-data notation. I'm now considering using some 3rd-party library like https://atlee.ca/software/poster/ 

Is there any recommended way to form the body? Or maybe some method in pulsar? I searched for similar code snippets in pulsar tests with no result

Hi,

The body needs to be a file-like stream containing data encoded using multipart/form-data notation.

You can use the encode_multipart_formdata function from pulsar utils:

from io import BytesIO
from pulsar.utils.httpurl import encode_multipart_formdata

files = {'testfile': b'svdhgscvhsgdvchsgcvhsavchvchsgdvcd'}
data, content_type = encode_multipart_formdata(files)
file_data = BytesIO(data)
 

file_data is what you are after I think, content_type is the value for the Content-Type header.
