Winappdriver: Certain Element attributes are not obtained by get_attribute()

[bharathp666]

Certain Element attributes are not obtained by get_attribute(self, name). The value is null or None. The attributes are present in the source. I'm trying to fetch the 'ToggleState' of a Button but turns out I always get None. Is there a solution?

From Python Bindings: self.driver.find_element_by_accessibility_id("openOnStartup").get_attribute('ToggleState')

{
    "AcceleratorKey": null,
    "AccessKey": null,
    "AutomationId": "openOnStartup",
    "ClassName": "ToggleSwitch",
    "FrameworkId": "XAML",
    "HasKeyboardFocus": "true",
    "HelpText": null,
    "IsContentElement": "true",
    "IsControlElement": "true",
    "IsEnabled": "true",
    "IsKeyboardFocusable": "true",
    "IsOffscreen": "false",
    "IsPassword": "false",
    "IsRequiredForForm": "false",
    "ItemStatus": null,
    "ItemType": null,
    "LocalizedControlType": "toggle switch",
    "Name": null,
    "Orientation": "None",
    "ProcessId": "16624",
    "RuntimeId": "42.5310242.4.84",
    "x": null,
    "y": null,
    "width": null,
    "height": null,
    "ToggleState": null,
    "IsAvailable": null
}

From Source: driver.page_source

...
<Button 
    AcceleratorKey="" 
    AccessKey="" 
    AutomationId="openOnStartup" 
    ClassName="ToggleSwitch" 
    FrameworkId="XAML" 
    HasKeyboardFocus="False" 
    HelpText="" 
    IsContentElement="True" 
    IsControlElement="True" 
    IsEnabled="True" 
    IsKeyboardFocusable="True" 
    IsOffscreen="False" 
    IsPassword="False" 
    IsRequiredForForm="False" 
    ItemStatus="" ItemType="" 
    LocalizedControlType="toggle switch" 
    Name="" 
    Orientation="None" 
    ProcessId="6996" 
    RuntimeId="42.3019514.4.21"
    x="89" 
    y="114" 
    width="76" 
    height="32" 
    ToggleState="Off" 
    IsAvailable="True" 
/>

Hi @bharathp666,

Can you try getting the Toggle.ToggleState attribute instead of ToggleState? E.g.

self.driver.find_element_by_accessibility_id("openOnStartup").get_attribute('Toggle.ToggleState')

Alternatively, toggle button control state can be inspected using the Selected property as shown in the following sample test: https://github.com/Microsoft/WinAppDriver/blob/v1.1/Tests/UWPControls/ToggleButton.cs#L97

@timotiusmargo both worked! thanks

self.driver.find_element_by_accessibility_id("openOnStartup").get_attribute('Toggle.ToggleState')
self.driver.find_element_by_accessibility_id("openOnStartup").is_selected()

Thanks @bharathp666 driver.PageSource works really good to get all the element attributes.
