How can I ignore the VSTest err msgs in my Windows Store app?

Question

When I build my Windows Store App, it shows me output from Tests:

------ Discover test started ------
Failed to configure settings for runsettings plugin 'VSTest Run Configuration' as it threw following exception:
'An error occurred while parsing EntityName. Line 1, position 8.'
Please contact the plugin author.
========== Discover test finished: 0 found (0:00:00.1350029) ==========

• and at the bottom of the window I see, "Unexpected error detected. Check the Tests Output Pane for details"

I don't care about this or want to see it (for now, anyway). I haven't got any tests set up. How can I hush up the Test nazi?

UPDATE

I don't know if there's a direct connection, but after installing the SQLite package updates for Windows 8 and then Windows 8.1, those weird, rogue, non-compilation-blocking "exception" messages went away.

As Kip Dynamite would say, "Dang it!!!" I wrote too soon; that same err msg is now back again.

UPDATE 2

It seems that changing my package name on the Packaging tab of Package.appxmanifest from [some GUID] to [companyName.appName] solved it...butt Y?

UPDATE 3

One time only (it's baaaaack!)

Answer 1

I've just had this issue for the last day or so, preventing me from running the unit tests in my projects.

The error An error occurred while parsing EntityName. Line 1, position 8. is what you would get back from an XmlReader if there is an error parsing xml, for example unescaped characters.

In my case I had an & in a folder name at a higher level. Renaming the folder then Build > Clean solution seems to have fixed the issue.
