So, I just wanted to answer my own question, to close the loop on this
matter. If you have a class that uses pure JUnit 4 style, then you can
run individual test methods without getting the "Unrooted Test" problem.
In other words, don't extend TestCase (or a subclass of TestCase).
In my own case, even though I thought I was using annotations to mark my
@Test methods, Eclipse was using the JUnit 3 compatibility mode.
Eclipse's test runner insisted to run all methods whose names start with
"test".

No. Neither. It doesn't seem to be related to test suites.

We had the same issue. However, we created a new parent class that has
all the useful code the old parent did, but doesn't inherit from
TestCase. Now we're all switched over to doing things the new way,
which makes it easier to use Eclipse and JUnit together.

I think you're right about the Eclipse test runner not being quite
correct. But I'm not on any Eclipse forums, and I'm skeptical they
would fix the problem anyhow since it's been there for years without
(apparently) too many complaints. Plus, the workaround of refactoring
our tests to use pure JUnit 4 is working, and is good enough for me.
Cheers,
Todd.
