How can I build a file-upload POST HTTP request with WebOb?

Question

I am using Ian Bicking's WebOb to very great effect in writing Python web application tests. I call webob.Request.blank('/path...'), and then use the resulting request object's get_response(app) method to invoke my web application. The response object that is returned lets me check the HTTP response's status code, content type, body, and so forth. Building a POST request is also quite easy:

Request.blank('/path/under/test/', POST={'query': 'some text'})

But now I have run across a bit of a puzzle: I need to test a view in my web application that expects a file upload, and I cannot quite figure out how WebOb represents that particular kind of POST. Does anyone know how to build a WebOb request with one or more file-upload fields inside?

Answer 1

You can use WebTest for that, see this TestApp.post arguments here.

Answer 2

As of a couple days ago you can do:

req = Request.blank('/path/under/test', 
                    POST={'query': 'some text', 'upload': ('filename', 'content')})

This was brought in in this commit, and has not yet been released.
