Some of the tests use trace-cmd, others use perf, most just do echo and
cat into the tracing directory itself.
I've added these over the years and need to clean them up and put them
someplace public. Right now they are very specific to my machines.
There's also tests in tools/testing/selftests/ftrace. But the rules
for what can go into selftests limit what I can place in there. I will
be adding more tests there soon though.
