资产文件夹的路径，来自RSpec测试

Question

我想测试一个载波图像上传到模型，使用RSpec /水豚/工厂女孩的Rails。
这个特定的测试测试了图像应该存在的验证。

目前，我有这样的代码：

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，没有检测到图像，我得到这个错误：

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)>' 

我如何可以指定一个路径资产中的图像并将其用于测试？

或者，或者，测试载波图像上传的更好方法是什么？

如果这是你真正想要使用水豚这样从用户的角度做一个验收测试/集成测试：

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 

如果你是一个单元测试后，做这样的事情与FactoryGirl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 

现在在你的单元测试，你可以运行测试：

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