fixture_file_upload Example

/ Published in: Ruby

fixture_file_upload is another nifty Rails testing feature. It allows you to create "MIME-encoded content that would normally be uploaded by a browser input field." (Part in quotes straight from Agile Web Development with Rails, v2). Put your files to test in test/fixtures/files. You have to create the 'files' directory; rails doesn't do it for you.
