我在嘗試使用Capybara的attach_file方法測試圖片上傳是否適用於回形針時遇到問題。在使用Capybara attach_file方法測試上傳文件時遇到問題
rspec的返回這些錯誤如下： 失敗：
1) Upload Background Image cannot upload a background image
Failure/Error: page.attach_file('#artist_background_image', Rails.root + 'spec/Fixtures/Snow.jpg')
Capybara::ElementNotFound:
Unable to find file field "#artist_background_image"
# ./spec/models/artist_spec.rb:65:in `block (2 levels) in <top (required)>'
我的測試如下所示。我假定選擇文件按鈕是attach_file的選擇器，所以我使用了選擇器'#artist_background_page'的id。
describe 'Upload Background Image', js: true do
before :each do
p '================='
pp Artist.all
@artist = Artist.first || Artist.create(artist_name:'Double Stuff Oreos', email:'[email protected]', password:'letmein')
visit "/artists/" + @artist.id.to_s
pp @artist.id
pp @artist.artist_name
p @artist.errors.full_messages
click_button 'Log in'
fill_in 'Email', with: '[email protected]'
fill_in 'Password', with: 'letmein'
page.find('#loginButtonModal').click
page.find('#addBackgroundImagePrompt').click
page.attach_file('#artist_background_image', Rails.root + 'spec/Fixtures/Snow.jpg')
p Rails.root + 'spec/Fixtures/Snow.jpg'
click_button 'upload'
end
it "cannot upload a background image", js: true do
backgroundURL = @artist.background_image.url.include?('Snow.jpg')
p @artist.background_image.url
expect(backgroundURL).to be_truthy
end
end
但是，當我將選擇器更改爲'artist_background_page'而沒有ID'＃'符號時。 rspec的給了我不同的錯誤：

在這種情況下，模型的創建，但錯誤說，它不能找到它出於某種原因... 有沒有我可以使用在水豚附加文件的任何其他方法並測試成功上傳？
可能性失敗：
- 錯誤路徑文件上傳
- 使用錯誤的方法或無效的使用方法
- 有毛病服務器
