cucumber test file download

Question

Anybody have idea how to test file download using cucumber?

Answer 1

This worked for me based when using send_data like so send_data(data, :filename => "inventory_#{Date.today.to_s}.csv", :disposition => 'attachment')

Probably not best way to write the step, but it worked!

Then /^I should receive a file(?: "([^"]*)")?/ do |file|
  result = page.response_headers['Content-Type'].should == "application/octet-stream"
  if result
    result = page.response_headers['Content-Disposition'].should =~ /#{file}/
  end
  result
end

Answer 2

I found this to be a convenient way of testing for downloads, its a naiv way just testing for the headers put for most of the time its reasonable.

If you are using capbybara then put the following inside your step_definitions.rb

    Then /^I should get a download with the filename "([^\"]*)"$/ do |filename|
       page.response_headers['Content-Disposition'].should include("filename=\"#{filename}\"")
    end

Inside your feature you can now do:

    When I follow "Export as ZIP"
    Then I should get a download with the filename "contacts_20110203.zip"

Answer 3

I run selenium through chrome, when I'm testing that the csv has downloaded, I use the following in Ruby:

Then /^I should get a downloaded file for fleet: "(.*?)"$/ do |export|       
    puts Dir["C:/Users/**/Downloads/fleet_#{export}_export_all_*.csv"].last
end

It simply looks in the default download directory and confirms that the file is there and outputs the filename within cmd.
