I'm currently evaluating TestManager. I don't see any way to input estimated testing time for each manual test. I would like to be able to run a report that would show how many test have not yet been run, and total the remaining testing time based on the estimates input for each test. In other words, when my manager asks how much longer testing will take, I'd like to be able to say "We've run x out of y tests, and it should take about z days to finish the remaining tests". I asked a support guy from Rational, and he suggested working with the custom fields, but I don't think that will do what I need.
