wires fails to handle ActionChain with Keys

[EricRahm]

Attempting to perform an ActionChain containing keys fails in wires 0.6.2 on OS X. It's possible this doesn't work on other platforms and revisions. I am testing against selenium 2.49.2.

Reduced test:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

firefox_capabilities = DesiredCapabilities.FIREFOX.copy()
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/Applications/FirefoxNightly.app/Contents/MacOS/firefox'
driver = webdriver.Firefox(capabilities=firefox_capabilities)

driver.get('data:text/html,<a href="https://mozilla.org">Click This!</a>')
tag = driver.find_element_by_tag_name("a")

# Simulate ctrl-shift clicking the anchor tag.
action = ActionChains(driver)
ctrl_key = Keys.COMMAND # mac
#ctrl_key = Keys.CONTROL # not mac
action.key_down(ctrl_key).key_down(Keys.SHIFT).click(tag).key_up(Keys.SHIFT).key_up(ctrl_key).perform()

Resulting error:

Traceback (most recent call last):

I get the same error without an action chain in wires 0.8 (which has actually been renamed to geckodriver) on Firefox 47, Linux x64. I'm just sending an ENTER key using PHP:

$webDriver->execute(DriverCommand::SEND_KEYS_TO_ACTIVE_ELEMENT, array(
  'value' => array(WebDriverKeys::ENTER),
));

Please note that geckodriver implements action pipelining as described in the WebDriver specification, not Selenium.

The part of the specification that talks about actions has not fully been fletched out yet. However, @jgraham is working on it. I have read some early and promising drafts.

For these reasons I’m going to close this ticket as it refers to Selenium-specific behaviour.

@andreastt
Okay - but as I pointed out, the same error occurs without action pipelining: I'm just trying to send a key to the active element. (Or is that selenium specific too...? Sorry, I'm not very familiar with the driver specs.)

I receive the error:
org.openqa.selenium.UnsupportedCommandException: POST /session/d1c21b22-b928-4de7-a482-62453da092a5/keys did not match a known command (WARNING: The server did not provide any stacktrace information) (s. above for the full stack trace)

[jgraham]

In the webdriver spec the endpoint is /session/{session id}/element/{element id}/sendKeys, so I think this needs to be fixed in Selenium.

[lentschi]

I see - sorry for complaining about it in the wrong place then!

[andreastt]

@lentschi Yes, @jgraham is correct. Please report back if the same still fails with Element Send Keys.

[jgraham]

I see - sorry for complaining about it in the wrong place then!

No problem, thanks for reporting the issue! It's hard to tell from the outside when bugs are in selenium or wires or gecko itself.
