Net::ReadTimeout (Net::ReadTimeout) Selenium Ruby

I've seen a few posts related to timeout errors within Selenium. This is becoming more and more unbearable as it's rendering my test pack unusable. I'm testing a webpage currently in development.

I have a regression suite of around 300 test scenarios which has always worked until the latest update to firefox and selenium webdriver. Now for almost every other test i'm getting:

Net::ReadTimeout (Net::ReadTimeout) errors.

This can't be coincidence. Would anyone know of what could be causing the sudden timeout problems? I've tried going back to previous versions of webdriver and firefox.

It started to work again for me with FF32 and the selenium-webdriver-gem v2.43.0. Which versions do you use? - tessi
I'm using FF32.0.3 and webdriver 2.43.0. - Tom
Sorry, I'm out of 'luck' then. My FF 32.0.3 does work (on Ubuntu 14.04). - tessi
I'm finding that it's timing out at the same place everytime during automation, yet running manual tests do not encounter this problem. That's what is pointing me toward Selenium - Tom
I'm having the same issue, did you get to solve it? - mrcasals

Another option to use RSpec::Retry which adds a retry option for intermittently failing specs.

require 'rspec/retry'

RSpec.configure do |config|
  # show retry status in spec process
  config.verbose_retry = true
  # Try twice (retry once)
  config.default_retry_count = 2
  # Only retry when Selenium raises Net::ReadTimeout
  config.exceptions_to_retry = [Net::ReadTimeout]
end

The default timeout is 60 seconds. One thing to try is to adjust the internal timeout to see if that fixes it:

Capybara.register_driver :selenium do |app|
  profile = Selenium::WebDriver::Firefox::Profile.new
  client = Selenium::WebDriver::Remote::Http::Default.new
  client.timeout = 120 # instead of the default 60
  Capybara::Selenium::Driver.new(app, browser: :firefox, profile: profile, http_client: client)
end
