Looks good.  I guess we will have to find out be experience how fragile or robust are these new tests.  Thank you for cross-linking from testing.md to building.md.  I remember when I first worked with gtest the information was split between the two files, but not cross-linked, and I found it confusing to put the pieces together myself.  This makes learning gtest on hotspot easier for the next person, as @DingliZhang says.
