使用:Ruby 2.4.0p0Rails 5.2.3在运行测试用例时:有错误:
我的测试用例就像:
require 'test_helper'
class SubscriptionsControllerTest < ActionDispatch::IntegrationTest
test "Can reach to index " do
get subscriptions_url
assert_response :success
end
结束
错误:
SubscriptionsControllerTest#test_Can_reach_to_index_:
ActionView::Template::Error: Can't resolve image into URL: undefined method `[]' for nil:NilClass
app/views/subscriptions/index.html.erb:43:in `_app_views_subscriptions_index_html_erb__900758959545617488_70234463713200'
test/controllers/subscriptions_controller_test.rb:6:in `block in <class:SubscriptionsControllerTest>'
但是当手动打开ui时,图像会正确加载。你能建议出什么问题吗?视图中的image_tag位于第43行。
<%= image_tag 'tukacad_1.png', alt: '', class: "img-responsive" %>
