These changes should not be done, IMO. Most of our
tests are diff based, and therefore it is ok to write
a statement just to print it. It is not only simpler, but
also allows to print the actual value, if it didn't match
the expected value.

For example, if n_workers becomes not 0, we would see its
actual value in the diff. When we use assert(), we won't
see anything except an error message 'assertion failed'.

I propose to allow writing non-functional statements in
test/ dir.
