我需要使用 Capybara 和 Selenium 测试文件上传页面。
我写了这个测试:
require 'rails_helper'
describe 'Images', type: :feature do
before(:each) do
@user = create(:user)
visit '/users/sign_in'
fill_in 'sing-in-email-input', with: @user.email
fill_in 'sign-in-password-input', with: @user.password
click_button 'btn-sign-in'
visit '/categories'
click_on 'btn-new-category'
expect(current_path) == new_category_path
fill_in 'category_name', with: 'Test'
click_button 'btn-create category'
visit '/categories'
first('.fa', :visible => false).click
expect(current_path) == category_path(id: Category.last.slug.to_s)
end
it 'should allow a registered user to create image and go to it page', js: true do
click_on 'btn-upload-images'
expect(current_path) == new_image_path(id: Category.last.slug.to_s)
attach_file('image[image]',
File.join(Rails.root, '/spec/fixtures/solnce-kosmos-merkuriy.jpg'), :visible => false)
click_on('btn-upload-img')
end
end
我无法继续编写此测试并检查此图片是否已成功上传，因为在这一行:
click_on('btn-upload-img')
我遇到了这个错误:

我检查过我确实有这个文件
/spec/fixtures/solnce-kosmos-merkuriy.jpg
在正确的地方。
这是我的/config/initializers/carrierwave.rb
if Rails.env.test? || Rails.env.cucumber?
CarrierWave.configure do |config|
config.storage = :file
config.enable_processing = false
end
# make sure our uploader is auto-loaded

我所有其他的 Capybara 和 RSpec 测试都工作正常。
请帮助我了解此问题的原因以及如何解决和预防。
如果可以帮助解决这个问题，我可以提供更多信息。
UPDATE 1
阅读 Thomas Walpole 的评论后，我决定更新我的代码并尝试一些其他功能。 我包括新 gem
gem 'database_cleaner'
我还添加了新代码来清除测试上传的代码。 这里更新了 rails_helper.rb
require 'support/factory_bot'
require 'spec_helper'

end
end

DatabaseCleaner.clean_with(:truncation)
end
config.around(:each) do |example|
DatabaseCleaner.cleaning do

end
end
config.after(:all) do

这是我更新的测试

正如 Thomas Walpole 告诉我的那样，我检查了测试日志并看到了下一个(关于当前测试):

据我了解，图片已成功上传。 但是我仍然得到这个错误
Failure/Error: raise ActionController::RoutingError, "No route matches [#{env['REQUEST_METHOD']}] #{env['PATH_INFO'].inspect}"
ActionController::RoutingError:
No route matches [GET] "/home/Anton-S/RubymineProjects/rails_projects/gallery/spec/support/uploads/image/image/12/solnce-kosmos-merkuriy.jpg"
UPDATE 2
不幸的是，我找到的唯一解决方案是设置 /config/environments/test.rb
config.action_dispatch.show_exceptions = true
但我仍然认为有更好的解决方案。
最佳答案
因此，从日志中，我们可以看到文件正在成功上传。
问题是当显示页面呈现时，图像被添加到 HTML 中，其 URL 类似于 '/home/Anton-S/RubymineProjects/rails_projects/gallery/spec/support/uploads/image/image/12/solnce-kosmos-merkuriy.jpg' 这将不起作用，因为 Rails 应用程序不会响应应用程序根目录中 public 目录之外的随机文件。这样做将是一个巨大的安全问题。最简单的解决方案是将图像存储到 public 目录中，以便 Rails 应用程序将它们作为静态 Assets 提供。类似的东西
def cache_dir
"public/test/uploads/tmp"
end
def store_dir
"public/test/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
注意:我还评论了您对 have_current_path 匹配器的使用。
关于ruby-on-rails - capybara 上传图片问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48499129/
