ruby-on-rails - fixture_file_upload具有{file}不存在错误

Question

以下是我上传文件的测试代码。

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

 it "should be able to upload file" do
  post :upload_csv, :upload => @file
  response.should be_success
 end
end

但是，当我运行rspec spec时，它产生了以下错误

Failure/Error: @file = fixture_file_upload('test.csv', 'text/csv')
 RuntimeError:
   test.csv file does not exist
 # ./spec/controllers/quotation_controller_spec.rb:29:in `block (3 levels) in <top (required)>'

我已经在很多地方搜索过，但是我仍然找不到背后的原因。任何想法？

Fixture_file_upload基本上仍然可以使用。您只需要确保spec_helper.rb文件中的装置路径未注释且正确设置为spec/fixtures路径并包含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"

  ...

并且在要在测试中指定文件的位置，请确保在文件名前加上“ /”，如以下示例所示：

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

文件的绝对路径是 config.fixture_path中指定的基本路径加上 fixture_file_upload函数调用中指定的相对路径。因此，在此示例中，必须将 file.csv放在 #{::Rails.root}/spec/fixtures/files/data.csv中
