Currently In test panel, it shows test group and test name and duration for each test.

Proposed improvements:

For each test group display number of tests, number of passed tests, accumulated duration of all tests in the group

Project Name +----+ 14 tests total, 8 tests passed, 0.1 seconds

  object_test.dart +-----+ 14 tests total, 8 tests passed, 0.1 seconds

     group_test +-----+ 8 tests total, 8 test passed, 0.05 seconds

     individual_test +------+ 0.003 seconds

the goal is have a glimpse on total passed tests and total duration for the whole project, each test file and test group.
