I want to click a GoogleMap pin in RSpec

Introduction

I wanted to write a test that clicks a pin on GoogleMap in RSpec, but I'm addicted to it, so it's a memorandum. Please note that the sources and error codes listed are the output ones, omitting unnecessary ones.

environment

• macOS 10.15.6
• Ruby 2.5.7
• Rails 5.2.3
• gem capybara
• gem selenium-webdriver

Target

I want to test if infowindow is displayed by clicking a pin in GoogleMap

problem

• Pin could not be clicked in capybara
• Clicking on the img tag Selenium :: WebDriver :: Error :: ElementClickInterceptedError:
• Click the map tag Selenium :: WebDriver :: Error :: ElementNotInteractableError:

Cause

• If the element you want to search is display: none, disabled, hidden, you cannot search with capybara.
• The height of the element you want to search is 0px, so it cannot be recognized by capybara.

solution

Can be clicked by finding the area tag with the visible: false option

googlemap.html

<div id="map"> //Whole map
  <img src="https://maps.gstatic.com/mapfiles/api-3/images/spotlight-poi2_hdpi.png " usemap="#gmimap0"> //Pin image
  <map name="gmimap0" id="gmimap0">
    <area> //Click this guy and it's ok
  </map>
</div>

googlemap_spec.rb

require 'rails_helper'

RSpec.describe "GoogleMap", type: :system do
  describe "The page where GoogleMap is displayed" do
    context "Checking the operation of GoogleMap", js: true do
      it "Click the pin to display infowindow" do
        pin = find("map#gmimap0 area", visible: false)
        pin.click
        expect(page).to have_css "div.infowindow" #Test for the presence of the infowindow class
      end
    end
  end
end

Bad pattern part 1

Find and click on the pin's img tag

• You cannot click the img tag in the first place
• Selenium::WebDriver::Error::ElementClickInterceptedError:
• A hint that the area tag is clickable is displayed

googlemap_spec.rb

#Find and click on the pin's img tag
  describe "The page where GoogleMap is displayed" do
    context "Checking the operation of GoogleMap", js: true do
      it "Click the pin to display infowindow" do
        pin = find("img[src$='spotlight-poi2_hdpi.png']") #Search for pin images
        pin.click
        expect(page).to have_css "div.infowindow"
      end
    end
  end

#I can't click the img tag Error
#You can click the area tag

Learn

• If you want to search for hidden elements with capybara, you can click with find with visible: false option
• Don't miss the hint hidden in the error code
