Rspec. assert_select deprecated?

In assert_select (ActionController::Assertions::SelectorAssertions) - APIdock I see that assert_select was deprecated.

Yes, when I run rails generate scaffold SqlStatement
title:text{120}
description:text
sql_stmt:text

``

I find the following code generated in ~/spec/views/sql_statements/index.html.erb_spec.rb require ‘rails_helper’

RSpec.describe “sql_statements/index”, type: :view do before(:each) do assign(:sql_statements, [ SqlStatement.create!( :title => “MyText”, :description => “MyText”, :sql_stmt => “MyText” ), SqlStatement.create!( :title => “MyText”, :description => “MyText”, :sql_stmt => “MyText” ) ]) end

it “renders a list of sql_statements” do render byebug assert_select “tr>td”, :text => “MyText”.to_s, :count => 2 assert_select “tr>td”, :text => “MyText”.to_s, :count => 2 assert_select “tr>td”, :text => “MyText”.to_s, :count => 2 end end

``

I find no mention of assert_select in File: README — Documentation by YARD 0.8.7.6

I find assert_select defined in ~/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/rails-dom-testing-2.0.3/lib/rails/dom/testing/assertions/selector_assertions.rb .

What am I not understanding?

So is it deprecated? What’s it replaced by? Where can I find documentation?

apidock things things are deprecated when they move - it doesn’t know it was extracted into the rails-dom-testing gem

I find no mention of assert_select in http://rspec.info/documentation/3.6/rspec-rails/

The rails specific assertions aren’t part of rspec-rails (you can still use them because rspec-rails wraps the rails testing facilities). ALthough rspec doesn’t really care what assertion library you use, I’ve more commonly seen people use the capybara rspec matches in such cases (expect(rendered).to have_css(‘tr>td’, count: 2, …)

So … where can I find current documentation on assert_select?

Is assert_select an Rspec facility or a wrapper around some other facility I need to learn?

If it isn’t apparent, Fred, thank you.

It was extracted from rails into the rails-dom-testing gem, so I would start with https://github.com/rails/rails-dom-testing/blob/master/README.md
