Question

我正在尝试使用RSpec / capybara / Factory girl for Rails测试载波图像上传到模型。
此特定测试测试图像应存在的验证。

目前，我有这段代码：

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

但不知何故未检测到图像，我收到此错误：

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)>'

如何在资源中指定图像的路径并将其用于测试？

或者，测试载波图像上传的更好方法是什么？

如果这是验收测试/集成测试，你实际上想要从用户角度使用capybara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，请使用FactoryGirl

中的spec/factories/factory.rb执行相应操作

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

现在在您的单元测试中，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
