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

This is how I did it with Rails 6, RSpec and Rack::Test::UploadedFile

describe 'POST /create' do
  it 'responds with success' do
    post :create, params: {
      company: {
        logo: Rack::Test::UploadedFile.new("#{Rails.root}/spec/fixtures/test-pic.png"),
        name: 'test'
      }
    }

    expect(response).to be_successful
  end
end

DO NOT include ActionDispatch::TestProcess or any other code unless you're sure about what you're including.
