rspec 1.3.0/capybara 0.3.9/seleniumでファイルのダウンロードをテストするには？

Question

こんにちは友人私はカピバラでファイルのダウンロードをテストしたいです。

私は

page.response_headers['Content-Type'] 

を試してみましたが、しかし、それはカピバラ:: NotSupportedByDriverError例外が発生します。

私はまた、任意のヘルプ感謝 'alertが発生していない' これはメッセージで失敗し

を

page.driver.browser.switch_to.alert.text 

を試してみました。

ありがとうございます。

Answer 1

リンクをクリックすると、* .pdfファイルを受け取ります。

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

セレンでは機能しません。したがって、javascriptドライバではなく、よりよく指定してください。私はそれがRackTestで動作すると確信しています。

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

Answer 2

私は同様のものを実装しようとし、何時間も費やしました。最後に私はいくつかの解決策を持っています、多分それはあなたのためにも適しています。
