Как проверить загрузку файла с помощью rspec 1.3.0/capybara 0.3.9/selenium?

Ответ 1

Я тестировал, что когда я нажимаю ссылку, я должен получить файл *.pdf.

click_on "link_to_pdf"
page.response_headers['Content-Type'].should eq "application/pdf"

Это не работает с селеном, поэтому лучше указать не драйвер javascript. Я уверен, что он работает с RackTest.

feature "Download pdf", :js => false do
end

Ответ 2

Я попытался реализовать что-то подобное и потратить много часов. Наконец, у меня есть какое-то решение, возможно, оно подходит и вам.
