Here's one way of doing it without writing a SQL query, In the Test Lab screen select Analysis and click on <Summary> Cross Test Sets. When the graph comes up Select "Plan: Test Name for both the X Axis and Grouped by drop-downs. Then click on Filter and select "Exec Date" and select Yesterday if that's what you want it for or Today if you are running it at the end of the day. Set the filter and select "Refresh". Then click on the "Data Grid tab" and go to the bottom right. The number in the last cell will be the total test run for yesterday. Save your Graph so that you can reuse it every time you need it.
