I would think on better name - no need to include "InProcess" in name.
MixinBasedBT, or maybe ConfigurableBT would go.

Done.

+  // to the testing process and do set ups needed for them in proper time.
+  // To do this you need to derive Mixin, implement
+  // all the methods you need there and (if needed) reload set ups and tear
+  // downs
+  // for things that you would usually do in those of the test, but which are
+  // connected
+  // to the mixin, not to the test itself.
+  // Finally, AddMixin() should be called in the test's constructor for each
+  // mixin.

Some comments for these methods (maybe copied from InProcessBT?)

Done.
