WebDriver: pressed virtual keys not correctly handled in action sequences

• Component: WebDriver
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

We are assuming that only one virtual key can be pressed and that a key up always releases the pressed virtual key if any. We should keep a list of pressed keys and remove them from the list when key up happens for them.

Can this be tested?

Where does currentState.pressedVirtualKeys get emptied?

> Source/WebDriver/Session.h:206
> +        HashSet<String> pressedVirtualKeys;

Would this be better off as a Vector? Do you want the keys replayed in order?

I'm not sure how this is related.

It's already tested, this fixes imported/w3c/webdriver/tests/perform_actions/key_modifiers.py::test_shift_modifier_generates_capital_letters[\ue008] and imported/w3c/webdriver/tests/perform_actions/key_modifiers.py::test_shift_modifier_generates_capital_letters[\ue050]

The keys are removed when the keyup happens for them.

You can get keyDown(Shift), keyDown(Control), keyUp(Shift), keyUp(Control) for example.

There are actually two issues the tests, one is that the virtual key pressed is lost when any other keyup happens, and the other is that we don't translate the keyvals when modifiers are present. I need both changes to fix those tests. I can split the patch, but I think they are related enough.
