Add metric for number of profiled tests and create dashboard widget to display it

<Freddy Mallet> I mean creating a measure is a good way to access the resource through a drilldown and the measure could be ... "number of profiled unit tests". So this measure will be displayed in the project dashboard and if the user click on it, all unit test (resource) with profiling information will appear.
<Evgeny Mandrikov> Yes - it's very good idea. But I decided to call it "number of profiled tests", because we also need profiling for integration-tests.
