1254486 - Invalid selectors should return error when finding multiple elements

Status: RESOLVED FIXED

(Remote Protocol :: Marionette, defect)

Description

[Andreas Tolfsen ❲:ato❳]

Currently the following assertion is true in Marionette:

    els = find_elements("anon", None)
    assert els == []

This passes in an invalid selector expression and returns an empty set, unlike the singular find element call, which returns an InvalidSelectorError instead:

    find_element("anon", None)

I would expect invalid selector expressions to always return an error, irregardless whether you use the singular or multiple find element command.

Appears to be fixed:

```
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

caps["marionette"] = True
caps["binary"] = "/Applications/Firefox48.app/Contents/MacOS/firefox-bin"

ff = webdriver.Firefox(capabilities=caps)
ff.get("https://google.com/")

ff_the_internet = ff.find_elements("anon", "")
```


WebDriverException: Message: Unknown locator strategy anon
