How to configure read_timeout and open_timeout for Selenium in Ruby?

Question

I'm getting this exception when calling goto() via Watir:

It seems that I can modify the timeouts, but I don't understand how.

They are used here, but how do I configure them?

Answer 1

You can refer to Documentation Ruby-Bindings : Internal timeouts

From Documentation : Internal timeouts Internally, WebDriver uses HTTP to communicate with a lot of the drivers (the JsonWireProtocol). By default, Net::HTTP from Ruby's standard library is used, which has a default timeout of 60 seconds. If you call e.g. Driver#get, Driver#click on a page that takes more than 60 seconds to load, you'll see a Timeout::Error raised from Net::HTTP. You can configure this timeout (before launching a browser) by doing:

  client = Selenium::WebDriver::Remote::Http::Default.new
  client.read_timeout = 120 # seconds
  driver = Selenium::WebDriver.for :remote, http_client: client

In Watir it may be something like

caps = Selenium::WebDriver::Remote::Capabilities.chrome          
client = Selenium::WebDriver::Remote::Http::Default.new
client.read_timeout = 600 
client.open_timeout = 600 
driver =  Watir::Browser.new :chrome, :desired_capabilities => caps, 
:http_client => client
