I wanted to see if there was a way to publish the progress of ongoing manual test results, unfortunately, this is not supported in V1 however some advice from the dev team on what is possible:
"The closest approximation for this version is as follows:
Make sure all of the tests have been run and published at least once so that the TFS server knows about them.
Break up your manual tests into groups and run each group as a test run.
As each test run completes, publish it against a consistent build.
The test manager can now look a the number of tests published against the build and calculate how many are remaining. "
