DataAttribute with disposable data

[rick-palmsens]

I am writing some integration tests where we have multiple hardware devices connected to the build server, and we run the test for each device separately. I did the whole SupportsDiscoveryEnumeration thingy to prevent access to the devices during discovery.

But now I'm dealing with the following issue: how do I dispose my data? At first I did basically this:

yield return device;
device.Dispose();

But then it turned out that GetData() is completely enumerated BEFORE running any tests, so my device ended up being disposed before the test.

So at this point I don't know where I can dispose of my connection. Especially with physical hardware it is important to properly close the connection. Is there any kind of extension point where I can release data generated by a DataAttribute?

The fact that your data items implement IDisposable is enough: we will automatically call Dispose() when we're done with the data item. There's no need for you to try to call Dispose() yourself.
