Now, it's pretty easy to just generate a log. On your Run Profile under Set Log File Options, just select 'Create a log file and stop run. Do not export to data source (test only)' as shown below.
However, the output log file is in XML format. In my opinion, you can't present this to a customer but it's a great format for further processing using Powershell or similar. I chose to create a simple XSLT for formatting the output.
If you have similar needs, grab the XSLT file here (https://skydrive.live.com/redir.aspx?cid=75f650a487e85151&resid=75F650A487E85151!161&parid=75F650A487E85151!150)
This is not the HTML report to rule them all, but it's a start and you can edit and change the HTML as you like.
<?xml:stylesheet type="text/xsl" href="ExportLog.xslt" ?>
