fixture_file_upload(path, mime_type = nil, binary = false)
Shortcut for Rack::Test::UploadedFile.new(File.join(ActionDispatch::IntegrationTest.file_fixture_path, path), type):
post :change_avatar, params: { avatar: fixture_file_upload('spongebob.png', 'image/png') }
Default fixture files location is test/fixtures/files.
To upload binary files on Windows, pass :binary as the last parameter. This will not affect other platforms:
post :change_avatar, params: { avatar: fixture_file_upload('spongebob.png', 'image/png', :binary) }

Passing a path to `fixture_file_upload` relative to `fixture_path` is deprecated.
In Rails 7.0, the path needs to be relative to `file_fixture_path` which you
haven't set yet. Set `file_fixture_path` to discard this warning.
