Ruby on rails 从RSpec测试到资产文件夹的路径

我正在尝试使用RSpec/capybara/Factory girl for Rails测试一个carrierwave图像上传到一个模型。
此特定测试测试是否应显示图像

目前，我有以下代码：

it "should accept a spotlight record with spotlight info" do
  feature = create :feature, spotlight: true, spotlight_description: "description", spotlight_image: File.open(Rails.root.join "/app/assets/shopstar_logo_stamp.png")
  expect(feature).to be_valid
end

但不知怎的，图像没有被检测到，我得到了这个错误：

Failures:

  1) Feature validations should accept a spotlight record with spotlight info
     Failure/Error: feature = create :feature, spotlight: true, spotlight_description: "description", spotlight_image: File.open(Rails.root.join "/app/assets/shopstar_logo_stamp.png")
     Errno::ENOENT:
       No such file or directory - /app/assets/shopstar_logo_stamp.png
     # ./spec/models/feature_spec.rb:32:in `initialize'
     # ./spec/models/feature_spec.rb:32:in `open'
     # ./spec/models/feature_spec.rb:32:in `block (3 levels) in <top (required)>'

故障：
1） 功能验证应接受具有聚光灯信息的聚光灯记录
失败/错误：feature=create:feature，spotlight:true，spotlight\u description:“description”，spotlight\u image:File.open（Rails.root.join）/app/assets/shopstar\u logo\u stamp.png）
Errno:：enoint:
没有此类文件或目录-/app/assets/shopstar\u logo\u stamp.png
#./spec/models/feature_spec.rb:32:in'initialize'
#./spec/models/feature_spec.rb:32:in'open'
#./spec/models/feature_spec.rb:32:in'block（3层）in'

如何在资产中指定图像的路径并将其用于测试？

或者，测试carrierwave图像上传的更好方法是什么？

如果这是一个验收测试/集成测试，您实际上希望从用户角度使用水豚这样做：

feature 'user uploads image' do
 scenario '#Image' do
    count = ImageModel.count
    visit new_image_path

    attach_file('css_selector_here', File.join(Rails.root, '/spec/support/herst.jpg'))
    click_button('Submit')

    expect(page).to have_content('Image uploaded successfully!')
    expect(ImageModel.count).to eq(count + 1)
  end
end

如果您正在进行单元测试，请在

spec/factories/factory.rb

Factory.define :feature do |f|
  f.spotlight true
  f.spotlight_description "description"
  f.spotlight_image { Rack::Test::UploadedFile.new(File.join(Rails.root, 'spec', 'support', 'feature', 'images', 'shopstar_logo_stamp.jpg')) }
end

现在，在单元测试中，您可以运行测试：

it "should accept a spotlight record with spotlight info" do
  feature = create :feature
  expect(feature).to be_valid
end

这实际上是一个模型测试。对不起，如果我的问题不清楚的话。。我是测试新手嗨，马可-我的回答对你有帮助吗？如果是，请接受。
