fixture_file_upload has {file} does not exist error

Question

Below is my testing code for uploading file.

describe \"file process\" do
 before(:each) do
   # debugger
   @file = fixture_file_upload(\'test.csv\', \'text/csv         


        

Answer 1

Fixture_file_upload basically still works. You just need to make sure the fixtures path in your spec_helper.rb file is uncommented & correctly set to the spec/fixtures path & to include ActionDispath::TestProcess:

RSpec.configure do |config|
  config.include ActionDispatch::TestProcess

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  ...

And where you are specifying the file in your tests, be sure to precede your file name with '/' like the following example:

describe "POST /subscriber_imports" do
  let(:file) { { :file => fixture_file_upload('/files/data.csv', 'text/csv') } }
  subject { post :create, :subscriber_import => file }
  ...
end

The absolute path to the file is the base path specified in config.fixture_path plus the relative path specified in fixture_file_upload function call. So, in this example, file.csv must be placed in #{::Rails.root}/spec/fixtures/files/data.csv
