rspec 1.3.0/capybara 0.3.9/सेलेनियम के साथ फ़ाइल डाउनलोड का परीक्षण कैसे करें?

Question

हाय दोस्तों मैं capybara में फ़ाइल डाउनलोड का परीक्षण करना चाहता हूँ।

मैं

page.response_headers['Content-Type'] 

की कोशिश की है लेकिन यह Capybara :: NotSupportedByDriverError अपवाद को जन्म देती है।

मैं भी कोशिश की है

page.driver.browser.switch_to.alert.text 

यह संदेश 'नहीं चेतावनी मौजूद है'

सराहना की किसी भी मदद के साथ विफल रहता है।

धन्यवाद।

Answer 1

मैंने परीक्षण किया कि जब मैं एक लिंक पर क्लिक करता हूं तो मुझे * .pdf फ़ाइल प्राप्त करनी चाहिए।

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

यह सेलेनियम के साथ काम नहीं करता है, इसलिए जावास्क्रिप्ट ड्राइवर निर्दिष्ट करने के लिए बेहतर नहीं है। मुझे यकीन है कि यह रैकटेस्ट के साथ काम करता है।

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

Answer 2

मैंने कुछ ऐसा करने और कई घंटों तक खर्च करने की कोशिश की है। अंत में मेरे पास कुछ समाधान है, शायद यह आपके लिए भी उपयुक्त है।
