Hound chrome_driver timeout error

[praveenperera]

I'm trying to get a simple hound test working with my app, I figured out its an error with chrome_driver. I got it works perfectly fine with selenium + firefox and even with selenium + chrome.

However when using with chromedriver as the driver instead of selenium, it opens a new chrome window with data:, in the address bar and then timesout.

Here is my test:

defmodule AuthenticationIntegrationTest do
  use ExUnit.Case
  use Hound.Helpers

  hound_session

  test "the truth" do
    navigate_to("http://localhost:4000")
    assert current_url == "http://localhost:4000"
  end

end

I'm using Hound 0.7.5, thanks

Additional information:

• config file is as follows: config :hound, driver: "chrome_driver"
• text.exs has been changed to start the server on test
• chrome_driver was installed using Homebrew
• on OSX 10.11.1 El Capitan

@praveenperera Issue with HTTPoison actually. chromedriver has no problems. I've filed an issue https://github.com/edgurgel/httpoison/issues/86. Will wait for the author to take a look.

Header handling was fixed in hackney. In v0.7.6, I've updated the dependency to the latest httpoison. The new release should fix this issue. If you still have problems please do re-open this issue and let me know.

Hello, i would like write an script for automation browser using hound. In the practice, i have the following issue:

** (MatchError) no match of right hand side value: {:error, %HTTPoison.Error{id: nil, reason: :timeout}}

This is my code, it's very simple.

• In mix.exs defp deps do [{:hound, "~> 0.7.6"}] end
• In config/config.exs

  
  use Mix.Config
  config :hound, driver: "chrome_driver"
  

• In lib/scraper.ex

  
  defmodule Scraper do
  use Hound.Helpers
  def start do
      Application.ensure_all_started(:hound)
      spawn(fn() -> System.cmd("chromedriver", []) end)
      IO.puts "starting"
      Hound.start_session
      navigate_to "https://login.live.com/"
      find_element(:id, "i0116") |> fill_field('Elixir')
      Hound.end_session
  end
  end
  

  Sometimes the script only show the page, rarely it only reaches fill the field, almost always shows that error. Thank you in advance for your reply

I am getting this error when I try to run the test below. There error happens but the browser still launches. It seems like a timing error? I have selenium server running and I can see the sessions it creates on the hub. 13:32:12.294 [error] GenServer Hound.SessionServer terminating ** (MatchError) no match of right hand side value: {:error, :timeout} (hound) lib/hound/session_server.ex:78: Hound.SessionServer.handle_call/3 (stdlib) gen_server.erl:615: :gen_server.try_handle_call/4 (stdlib) gen_server.erl:647: :gen_server.handle_msg/5 (stdlib) proc_lib.erl:247: :proc_lib.init_p_do_apply/3 Last message: {:change_session, #PID<0.215.0>, :default, []} State: %{}

• In mix.exs [{:hound, "~> 1.0"}]
• In config.exs config :hound, browser: "firefox"
• In test/learn_hound_test.exs

defmodule LearnHoundTest do
  use ExUnit.Case
  use Hound.Helpers

  hound_session

  test "the truth"  do
    navigate_to("http://example.com/guestbook.html")

    element = find_element(:name, "message")
    fill_field(element, "Happy Birthday ~!")
    submit_element(element)

    assert page_title() == "Thank you"
  end
end

I am pretty new to Elixir so there could be a problem between the chair and keyboard but at the moment I am at a loss.

@blackoperat Hi, I suspect this is not an issue with Hound directly, but with the version of Selenium and Firefox. Firefox seems to be moving to the geckodriver to communicate with Selenium, so give a try to Selenium 3.0.0-beta2 with geckodriver (0.10.0 is the latest as writing this), it works perfectly for me.
