Class ActionController::TestUploadedFile

Parent: Object

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.

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