Using .nil? to check the presence of an element

[NaviHan]

The shopping cart has two products, normal product and personalised product

Against each normal product there is a "move to wishlist" button and there is no "move to wishlist" button for personalised product.

The test needs to validate the absence of the "move to wishlilist" button for the personalised product.

The move to wishlist buttons are idetified by the collection

buttons(:add_to_wishlist , :class => 'wishlist-container')

and each button is identified by the attribute "data-variationgroup" which containes the product ID passed to the test as a table

The page source of 1st product which is a personalised one and hence no move to wishlist button.

<div class="row add-wishlist-remove-buttons">
<div class="medium-5 xlarge-6 xxlarge-2 small-offset-7 large-offset-5 xlarge-offset-0  column">
<button type="submit" class="pointer remove-container" name="dwfrm_cart_shipments_i0_items_i0_deleteProduct" value="9351785508221" data-item-position="0">
<span class="icon icon-cross-standard-small-black"></span>
<span class="underline align-text remove-button-text">Remove</span>
</button>
</div>

</div>

2nd product which is a normal product

<div class="row add-wishlist-remove-buttons">


<div class="small-7 large-7 xlarge-3 xxlarge-2 column wishlist-wrapper">
<button type="button" data-variationgroup="2002690-02" data-productname="Woven Allycia Cold Shoulder Frill Wrap Dress" class="pointer wishlist-container">
<span class="icon icon-wishlist-bag-heart"></span>
<span class="underline align-text">Move to wishlist</span>
</button>
</div>

<div class="medium-5 xlarge-6 xxlarge-2   column">
<button type="submit" class="pointer remove-container" name="dwfrm_cart_shipments_i0_items_i1_deleteProduct" value="9351533603802" data-item-position="1">
<span class="icon icon-cross-standard-small-black"></span>
<span class="underline align-text remove-button-text">Remove</span>
</button>
</div>

</div>

What would be the best way to check the absence of the "move to wishlist" button for the 1st product?

One of my team members is using a logic

  def check_move_to_wishlist_link_presence product
    add_to_wishlist_elements.find{|el| el.data_variationgroup == product}.nil?
  end

this is calling nil on nil which return true.

Is this a good way? I see an issue where this passes even when the product itself is not there

<div class="row add-wishlist-remove-buttons">

<div class="small-7 large-7 xlarge-3 xxlarge-2 column wishlist-wrapper">

<button type="button" data-variationgroup="2002690-02" data-productname="Woven Allycia Cold Shoulder Frill Wrap Dress" class="pointer wishlist-container">

<span class="icon icon-wishlist-bag-heart"></span>

<span class="underline align-text">Move to wishlist</span>

</button>

</div>

<div class="medium-5 xlarge-6 xxlarge-2   column">

<button type="submit" class="pointer remove-container" name="dwfrm_cart_shipments_i0_items_i1_deleteProduct" value="9351533603802" data-item-position="1">

<span class="icon icon-cross-standard-small-black"></span>

<span class="underline align-text remove-button-text">Remove</span>

</button>

</div>

</div>

In the above html, if I represent the button name="dwfrm_cart_shipments_i0_items_i1_deleteProduct" as  buttons(:remove_line_items, :name => /deleteProduct/) then can I reach the other button with data-variationgroup="2002690-02" using the preceding_sibling?

remove_line_items_elements.find{|el| el.value == "9351785508221"}.preceding_sibling.present?

Doesnt work though. If that the case I could have solved the original issue with this code..

I have attached the html of the two line items on cart

The issue:-

How do we check the presence of a button which can only be identified by a custom attribute when the button itself is not there.
