Chapter 7 / 8
Chapter 7 / 10 - a bit overdone ;-)

Nothing new in Chapter 7 / 9.
Chapter 7 / 11 - not working.
Chapter 7 / 11 - refactored

and working.
Chapter 7 / 11 - refactored

to rid the macro of stuff that should be explicit.
Chapter 7 / 12
Chapter 7 / 12 - attempt at PersistenceTest.cpp.
Chapter 7 / 12 - get rid of TEST_P

No parameterized test is used in any of these
tests, nor does it show how to use them, so get
rid of all of that template stuff.
Chapter 7 / 12 - ported remaining tests

which produces many failures due to memory leak.
Chapter 7 / 12 - PersistenceTest.spp changes from 11.
Chapter 7 / 12 - ignore memory leaks for now.
