Let me just emphasise this with a short story. Before I release LTP I do
a lot of pre-release testruns to make sure that all tests works well on
a different distributions and kernel versions.

Before I wrote a script that automated this[1] i.e. runs all the tests in
qemu and filters out the interesting results it took me a few days of
manual labor to finish the task. Now I just schedulle the jobs and after
a day or two I get the results. Even if the tested kernel crashes, which
happens a lot, the machine is just restarted automatically and the
testrun carries on with a next test. All in all the work that has been
put into the solution wasn't that big to begin with it took me a week to
write a first prototype from a scratch.
