Get test count without running tests?

[bensashi]

Given a particular tag (e.g., "Functional:Regression Tests"), is there any Maven command that can be run (or brief code snippet) that would tell us the number of tests that should be run (i.e., the number we would expect to see in "Total" in the summary on the home page of the Serenity report if we were to actually execute using that tag)?

We are experiencing a problem where test scenarios occasionally get silently skipped (seemingly not executed, and fully absent from the report) when there is a failure in a Java class with multiple JUnit @test scenarios. That is the bigger issue, but it has proven difficult to diagnose.

In the meantime, it would be nice if we could run a command to see how many tests should be in the report so we can more easily flag the number of skipped tests in any given run.
