Does Capybara has_selector? wait like

Question

When I use Capybara's has_selector? does it wait and retry to try to find the dom node like the find() method does? I'm not finding any useful information in the docs below. I'm interested in the answer, but I'm really more interested in how I would deduce that information from the ruby docs (which always give me problems navigating).

Yes. If you look at the assert_selector source, it calls synchronize.

"Show source" is your friend, most rendered docs will have it. And then there is always the actual source code. Which, many times, will trump any rendered documentation.
