[thought] Stop on first test failure -> rerun everything verbosely on failure

[webknjaz]

Should I practice/recommend this?

$ python -Im pytest --help | grep fail
  -x, --exitfirst       Exit instantly on first error or failed test
  --maxfail=num         Exit after first num failures or errors
  --runxfail            Report the results of xfail tests as if they were not
  --lf, --last-failed   Rerun only the tests that failed at the last run (or all
                        if none failed)
  --ff, --failed-first  Run all tests, but run the last failures first. This may
  --lfnf, --last-failed-no-failures={all,none}
                        there are no previously (known) failures or when no
                        cached ``lastfailed`` data was found. ``all`` (the
                        emits a message about no known failures and exits
  --sw, --stepwise      Exit on test failure and continue from last failing test
                        Ignore the first failing test but stop on the next
                        failing test. Implicitly enables --stepwise.
                        (f)ailed, (E)rror, (s)kipped, (x)failed, (X)passed,
  --xfail-tb            Show tracebacks for xfail (as long as --tb != no)
                        failed tests. Default: all.
  --pastebin=mode       Send failed|all info to bpaste.net pastebin service
  --doctest-report={none,cdiff,ndiff,udiff,only_first_failure}
                        failure
  --doctest-continue-on-failure
                        failure
                        e.g. `-o strict_xfail=True -o cache_dir=cache`.
  --no-cov-on-fail      Do not report coverage if test run fails. Default: False
  --cov-fail-under=MIN  Fail if the total coverage is less than MIN.
                        strict_config, strict_markers, strict_xfail,
  strict_xfail (bool):  Default for the strict parameter of xfail markers when
                        xfail_strict)
                        (all/failed/none)
                        explanation when an assertion fails.
