Hello,
I am doing my first steps with rspec and did the following
observation.
I wanted to write a spec for a standard scaffold index view.
Now, my view spec looks like:
describe “/a_details/index.html.erb” do
it “should list all the details of as in an unordered list” do
assign[:a_details] = [‘test’]
render '/a_details/index.html.erb'
response.should have_tag("ul") do
with_tag("li") do
with_tag("div", "Name")
with_tag("div", "Details")
end
end
end
end
Can someone show me a direction and/or has a solution to this ?
When I run this I get:
ActionView::TemplateError in ‘/a_details/index.html.erb should list
all the details of shoes in an unordered list’
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
