Slow reporting when running thousands of test scenarios

[ben-manes]

When (ab)using parameterized tests to run thousands of times, the execution finishes in a reasonable amount of time. However, the UI report takes much longer to complete. Naively it seems like something that could be buffered by time/space to reduce the UI rendering lag. It is a bit annoying only because when stopping the test execution (e.g. a failure), the UI keeps going and going as it catches up.

yes, this is known issue, the solution could be, as you mentioned, buffered/batch ui updating.
i'm going to keep this ticket open if anybody would like to contribute the PR
