/*
This is used by Suite and test informers created as tests run, which therefore have
populated defined NameInfos. These informers are returned by info in FunSuite and Spec,
or passed to test methods that take an Informer in Suite, for example. If called by the
thread that constructed them, which is the thread that was executing the suite and the tests
inside the suite, then that NameInfo should be propagated. However, if a test starts other
threads for a multi-threaded test, and those threads apply the Informer, then the NameInfo
should *not* be propagated, because otherwise it could become very confusing to figure out
what came from where in the report. Threads started by the test could outlast the thread
that was running the test, for example. There will be a thread-name, so they can use that
to figure out who sent what. And threads that call these informers will share a Tracker with
the thread that was running the tests, so they should be ordered close together after
sorting by Ordinal. But that's it. NameInfo only goes out when the thread running a test
or suite applies the Informer.
This in turn means that a reporter may get hit by multiple threads sending InfoProvided
messages. If run with the Runner, that will be OK, because DispatchReporter will be in front
serializing events with its actor. If run() is invoked directly on a suite instance, such as
from the Scala interpreter, then it may not work. I think I may just say that when running
from the interpreter, say with run(), you may get interleaved output. This would only happen
when doing a multi-threaded test that starts threads that calls informer methods, likely a
rare case. Also, in that case I think it is reasonable to say you may get interleaved output
in the interpreter, so if you don't like that, use the Runner.
