You should be able to build whatever hierarchy you want.

You can in a sense. Automatic test units registered first though, thus you can't
recreate them, but should be able to access appropriate test unit.

Also automated test suites are "restartable" in C++ namespace sense.

This is not master test suite. Master test suite is managed by the framework. It
always exists. you create test units under it.

You can't add automatically registered test suite to the manual one for the
reasons explained above.

No. It's part of the foo_suite test suite. Use --log_level=suite to see all the 
test unit enter/leave messages.
