Defined in:
lib/action_controller/test_process.rb

Overview

Essentially generates a modified Tempfile object similar to the object you’d get from the standard library CGI module in a multipart request. This means you can use an ActionController::TestUploadedFile object in the params of a test request in order to simulate a file upload.

Usage example, within a functional test:

post :change_avatar, :avatar => ActionController::TestUploadedFile.new(Test::Unit::TestCase.fixture_path + '/files/spongebob.png', 'image/png')
