问题:

Is there a way to click a Google Maps overlay with capybara-webkit? What about Capybara using Selenium? I want to test the content of the info window once the marker is selected. I also want to test that there are n markers on the page.

回答1:

To test that there are n markers on the page:

expect(find('.gmap_container')['data-markers'].split('},{').count).to eq(n)

回答2:

This can be done, but requires a change to how you create your markers. You must instruct them to render as images rather than canvas elements:

new google.maps.Marker({
  position:  latLng,
  animation: google.maps.Animation.DROP,
  name:      business.get('name'),
  id:        business.get('id'),
  optimized: false, // <-- this is the stuff
  title:     business.get('name')
});

Then in your test, you can find('div[title="Business\ Title"]').click

If possible, you might want to consider doing this just for a test environment, but that's up to you and your needs.
