Does anybody know how to upload files in RoR Integration Tests?

I have seen lots on simulating uploads with Functional and Unit tests,  
but all efforts I have made so far do not encode the files as multipart  
form-data so they end up as a string.

I suspect I need to encode my post but don’t see how this can be done  
in the API.

Any pointers would be greatly appreciated!

that doesn’t help with integration testing, because the TestUploadedFile  
instance gets transformed into a string, yielding a

NoMethodError (undefined method `content\_type’ for  
“#ActionController::TestUploadedFile:0xa6ff4848”:String)

in the controller expecting an uploaded file.

Rails Cookbook also has a recipe for testing file upload, you may want  
to  
check it out. Only rough cut version is available now.
