使用 rspec - rails 测试文件上传 [英] test a file upload using rspec - rails

问题描述

我想在 rails 中测试文件上传，但不知道如何执行此操作.

I want to test a file upload in rails, but am not sure how to do this.

这是控制器代码:

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


    #Get Session ID
    sessid = session[:session_id]

    puts "

Session_id:
#{sessid}
"

    #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

我已经尝试过这个规范，但它不起作用:

I have tried this spec, but it doesnt work:

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 模拟文件上传?

推荐答案

您可以使用 fixture_file_upload 方法进行测试文件上传:将您的测试文件放在 "{Rails.root}/spec/fixtures/files" 目录

You can use fixture_file_upload method to test file uploading: Put your test file in "{Rails.root}/spec/fixtures/files" directory

before :each do
  @file = fixture_file_upload('files/test_lic.xml', 'text/xml')
end

it "can upload a license" do
  post :uploadLicense, :upload => @file
  response.should be_success
end

如果您需要 params['upload']['datafile']

it "can upload a license" do
  file = Hash.new
  file['datafile'] = @file
  post :uploadLicense, :upload => file
  response.should be_success
end
