Create a ActivePlatforms/IgnoredPlatforms Attribute for test methods/classes

[kazo0]

I'm submitting a

Feature Request

Current behavior

Currently we would need to something like the following for our test methods and classes.

if (AppInitializer.GetLocalPlatform() == Platform.Android
    || AppInitializer.GetLocalPlatform() == Platform.iOS))
 {
   // Do something
 }
else if  (AppInitializer.GetLocalPlatform() == Platform.Browser)
{
  // Do something else
}

Desired behavior

What would be nice and cleaner is some sort of ActivePlatforms attribute for test methods and classes.
So we can mark classes and methods by doing something like:

[ActivePlatforms(Platform.Android, Platform.iOS)]
public void MyTest() { }

Or maybe even an IgnoredPlatforms?

[IgnoredPlatforms(Platform.Browser)]
public void MyTest() { }

This feature is actually specific to the uno repository, let's move if there for now. Actually, you probably mean you want it for not-uno :)

My thinking was that this could be part of the Helpers within Uno.UITest. I see we do something similar for the UI Tests in Uno
