Can someone explain the output from running Bitcoin Core unit tests on Mac OS please? When I build and run the unit tests on Mac OS using the make check command the output contains these two summaries (images uploaded below). Why does the testsuite summary initially summarize zero tests and then later only summarize a small number of the unit tests? I checked with another Bitcoin Core Mac OS user and they get similar outputs.

 and .
This is the output for all platforms at the moment, not just MacOS. To paraphrase from sipa on IRC:


The first summary is bitcoin's own summary: because of some hackery to run unit tests in parallel, it currently shows no tests (even though they are executed).
The second and third summary are the output from make check for the built-in dependencies, secp256k1 and univalue respectively.
