It would make little sense to run the whole set of test cases on Travis,
but I have used Travis until recently in order to run a small set of test
scenario, for example, limiting the scope to
  buildman catch-all AArch64
  test/py sandbox
  test/py qemu-x86_64
by modifying .travis.yml.

Since going through the all test paths is a time-consuming task any way,
it always makes sense for me to run some critical tests first locally
(without revealing those activities in public).
