[ruby-on-rails] 使用rspec-rails測試文件上傳



Answers

我不確定您是否可以單獨使用RSpec測試文件上傳。 你嘗試過Capybara嗎?

從請求規範中使用attach_fileattach_file方法測試文件上傳很容易。

例如(這個代碼只是一個演示):

it "can upload a license" do
  visit upload_license_path
  attach_file "uploadLicense", /path/to/file/to/upload
  click_button "Upload License"
end

it "can download an uploaded license" do
  visit license_path
  click_link "Download Uploaded License"
  page.should have_content("Uploaded License")
end
Question

我想在rails中測試文件上傳,但不知道如何執行此操作。

這裡是控制器代碼:

def uploadLicense
    #Create the license object
    @license = License.create(params[:license]) 


    #Get Session ID
    sessid = session[:session_id]

    puts "\n\nSession_id:\n#{sessid}\n"

    #Generate a random string
    chars = ("a".."z").to_a + ("A".."Z").to_a + ("0".."9").to_a
    newpass = ""
    1.upto(5) { |i| newpass << chars[rand(chars.size-1)] }

    #Get the original file name
    upload=params[:upload]
    name =  upload['datafile'].original_filename 

    @license.format = File.extname(name)

    #calculate license ID and location
    @license.location = './public/licenses/' + sessid + newpass + name 

    #Save the license file
    #Fileupload.save(params[:upload], @license.location) 
    File.open(@license.location, "wb") { |f| f.write(upload['datafile'].read) }

     #Set license ID
    @license.license_id = sessid + newpass

    #Save the license
    @license.save

    redirect_to :action => 'show', :id => @license.id 
end

我試過這個規範,但它不起作用:

it "can upload a license and download a license" do
    file = File.new(Rails.root + 'app/controllers/lic.xml')
    license = HashWithIndifferentAccess.new
    license[:datafile] = file
    info = {:id => 4}
    post :uploadLicense, {:license => info, :upload => license}
end

如何使用rspec模擬文件上傳?




我沒有使用RSpec來完成這項工作,但我確實有一個Test :: Unit測試,它可以為上傳照片做類似的事情。 我將上傳的文件設置為ActionDispatch :: Http :: UploadedFile的一個實例,如下所示:

test "should create photo" do
  setup_file_upload
  assert_difference('Photo.count') do
    post :create, :photo => @photo.attributes
  end
  assert_redirected_to photo_path(assigns(:photo))
end


def setup_file_upload
  test_photo = ActionDispatch::Http::UploadedFile.new({
    :filename => 'test_photo_1.jpg',
    :type => 'image/jpeg',
    :tempfile => File.new("#{Rails.root}/test/fixtures/files/test_photo_1.jpg")
  })
  @photo = Photo.new(
    :title => 'Uploaded photo', 
    :description => 'Uploaded photo description', 
    :filename => test_photo, 
    :public => true)
end

類似的東西也可能適用於你。
