RSpec View Testing for Datagrid

[jonmchan]

I do a rails scaffold and it generates the standard rspec view tests:

    render
    assert_select "tr>td", :text => "Email".to_s, :count => 2
    assert_select "tr>td", :text => "First Name".to_s, :count => 2
    assert_select "tr>td", :text => "Last Name".to_s, :count => 2
...
    assert_select "tr>td", :text => "Company".to_s, :count => 2
  end

I was thinking about what the best way to do view specs with datagrid. Any best practices?

I generally don't test views. Especially with the default setup that is only one line of code. The test above makes sense for datagrid if you are really concerned.

Perhaps

RSpec.describe "contacts/index", type: :view do
  before(:each) do
    create_list(:contact, 11)
  end

  context "admin" do
    before(:each) do
      allow(view).to receive(:current_user).and_return(create(:admin))

      contact_grid = assign(:grid, ContactsGrid.new)
      assign(:pagy, pagy(contact_grid.assets)[0])
      assign(:records, pagy(contact_grid.assets)[1])
      render
    end

    it "renders a list of users with heading and paginations" do
      # do assert
    end
 end

And my index action

 def index
    @grid = ContactsGrid.new(params[:contacts_grid])
    @pagy, @records = pagy(@grid.assets)
    authorize @grid
  end
