问题
I've downloaded and installed the windows 8 consumer preview, and I'd like to figure out how to use the UI Automation API's to get data from metro style applications.
Background: I have a lot of automated tests which use the Microsoft UI Automation API's to interact with applications. The scripts are written in IronRuby against .NET 4
Initially, I'd simply like to check if the start menu is visible (and if so, close it)
According to Microsoft, the normal UI Automation API's should be able to access and control metro style applications, but the problem is, I can't figure out how my code can actually access the UI of metro applications? Our normal way of viewing UI automation data is using UISpy, however when I run UI spy under windows 8 and bring up a metro app, there is no mention of it... it seems like metro apps (including the start screen) are walled off from the desktop.
If I can't find the metro apps in UISpy, how can I find what their automation ID's are, and how could I find them from my automated test scripts?
回答1:
A few resources on UI automation which works in Metro style apps:
Here is a sample demonstrating it.
Here is a blog post explaining it.
This is a forum thread on the subject.
There is nothing about the app that stops traditional UI automation from working correctly. You may have to get updated tools to view the Metro style apps. Some ship with the Consumer Preview. Look for inspect.exe.

UI Automation tools can automate Metro applications. Check RIATest for example.
Stating from version 6.0 a number of features in RIATest are specifically targeted at Metro style application automation, particularly:
Ability to stay on top of Metro UI to allow you to simultaneously see your Metro application and RIATest IDE and minimize switching from Desktop to Metro screens when automating a Metro application.
Recording of actions performed on native Windows GUI elements (including Metro GUI). The recorder analyses your script code and reuses your variable names to generate cleaner recorded scripts similar to how you would hand-code an automation script.
Seamless workaround for bugs like this in Windows UI Automation implementation in Metro UI.
Disclaimer: I work for Cogitek, the RIATest company.

WinRT (aka "Metro Style") applications run in an sandbox. You cannot pierce the walls between applications, including to Desktop applications. This includes network isolation (you cannot refer back to localhost for example except in a development environment). There are a couple of exceptions to this such as the Share and Search contacts which allow for very specific types of interactions between apps.
It is this sandbox that is preventing UISpy from seeing the executing WinRT application in the background. I'm not sure how UISpy could work around this issue without some kind of development environment exception to the sandbox (similar to the network isolation exception) that isn't available in the consumer preview.
I'm also unaware of any announcements regarding when/if the UI Automation API will be supported for WinRT applications at this time.
