Win 10 Ie11 : Unable to set/get window size upgrading from IEDriver 3.4 to IEDriver 3.6

[andreabisello]

On
Windows 10 64 bit full stack updated
With
Selenium 3.6
IEDriver 3.6

this

from selenium import webdriver
browser = webdriver.Ie()
browser.set_window_size(1300, 1000)

will not change window size and this

print(browser.get_window_size())

returns

{'message': 'Command not found: GET /session/cca537b7-5bc0-49ee-972e-400d9cf1ddb5/window/size', 'value': None, 'error': 'unknown method'}

On Chrome set_window_size works and get_window_size returns the right dimension.

This is a regression , because with IEDriver 3.4, it works without error also on IE11.

Somewhat related to this, is there a reason Selenium doesn't raise an exception when a driver returns such an error? Browsing through the code it seems that an error should be raised by ErrorHandler.check_response() which ought to be called by WebDriver.execute() that WebDriver.get_window_size() ought to call. Based on the above description, it seems no error is raised and invalid data is simply returned to the user.

It looks like Python bindings implement incorrect commands for getting/setting window size:

            Command.W3C_GET_WINDOW_SIZE:
                ('GET', '/session/$sessionId/window/size'),
            Command.W3C_SET_WINDOW_SIZE:
                ('POST', '/session/$sessionId/window/size'),

No such commands are defined by specification, so bindings should instead fallback to rect commands. Just like Ruby bindings do.

@pekkaklarck Interesting, can you please raise a separate issue for that?

[pekkaklarck]

@p0deje Done. See #4948.

Fixed in ffce538, will be in the next release. I'll look at the other issue you added

[andreabisello]

with version 3.8 getter and setter works.
