As Alan wrote already, there is one log file per test file. If a test run
(per test file) fails, the log file is shown. See definition of Makefile
variable WRITE_LOG:

--8<---------------cut here---------------start------------->8---
## Save logs, and show logs for failed tests.
WRITE_LOG = > $@ 2>&1 || { STAT=$$?; cat $@; exit $$STAT; }
--8<---------------cut here---------------end--------------->8---

However, since we ran into a job timeout, the job has stopped before we
could see the log file. This is fixed now for process-tests.el, because
every single test is wrapped now by a timeout of 60 seconds, which let
the tests fail in time.

The Makefile knows also special handling when running on hydra, showing
the test progress unconditionally in the Makefile output. Currently, it
has the value:

--8<---------------cut here---------------start------------->8---
ifdef EMACS_HYDRA_CI
## On Hydra, always show logs for certain problematic tests.
lisp/net/tramp-tests.log \
: WRITE_LOG = 2>&1 | tee $@
endif
--8<---------------cut here---------------end--------------->8---

That is, running Tramp tests will always show the progress in the
Makefile output. We could use the same feature for emba if we want.
