unit testing - Rails test: test image_tag on view -

i'm writing view tests , want test image:

<%= image_tag "icon.png", class: "img-responsive" %>

so made test, not working:

it 'app logo' render assert_select 'img.img-responsive[src=?]', asset_path('icon.png') end

it works if utilize following, think not right way of doing it:

it 'app logo' render assert_select 'img.img-responsive[src=?]', '/assets/icon.png' end

what problem? right why test rspec?

try using capybara:

page.should have_selector(:xpath, xpath_of_the_image_element)

ruby-on-rails unit-testing view rspec

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
