When attempting to run MSTEST from the mstest plugin the plugin does not correctly wrap files in quotation marks. The problem occurs if the file being run after the /testcontainer switch requires quotation marks because it contains spaces in its path.

The help for cmd.exe specifically has requirements for calling cmd.exe /c that cause issues when both the executable for mstest and the test container have spaces in their paths.

The work around is to use the functionality in Jenkins that allows batch files to run mstest instead of the plugin.
