Re: [cherrypy-users] How to create "Fake File object" for Unit Testing?

[Vincent Le Goff]

Hello,

I'm not sure of what you want to do, but you can create a file-like
object (with read and readlines method) using StringIO objects.
This class is defined in the StringIO module for Python 2.7 and io
module for Python 3.X. Here's an example using Python 3:

>>> stream = io.StringIO("that works")
>>> stream.read()
'that works'
>>>

Hope that helps,

Vincent

Hi Tyrone,

I had written a small recipe on the subject:

https://bitbucket.org/Lawouach/cherrypy-recipes/src/50aff88dc4e24206518ec32e1c32af043f2729da/testing/unit/serverless?at=default

following this SO question:

http://stackoverflow.com/questions/14260101/unittesting-cherrypy-webapp/14261070#14261070

That may help.

attachment.file.read()

Does anyone have any familiarity writing unit tests for file objects?

Thank you!
