For example: # # 1) serial, no coverage, temp install: # ./run-tests.py test-s* # 2) serial, no coverage, local hg: # ./run-tests.py --local test-s* # 3) serial, coverage, temp install: # ./run-tests.py -c test-s* # 4) serial, coverage, local hg: # ./run-tests.py -c --local test-s* # unsupported # 5) parallel, no coverage, temp install: # ./run-tests.py -j2 test-s* # 6) parallel, no coverage, local hg: # ./run-tests.py -j2 --local test-s* # 7) parallel, coverage, temp install: # ./run-tests.py -j2 -c test-s* # currently broken # 8) parallel, coverage, local install: # ./run-tests.py -j2 -c --local test-s* # unsupported (and broken) # 9) parallel, custom tmp dir: # ./run-tests.py -j2 --tmpdir /tmp/myhgtests # # (You could use any subset of the tests: test-s* happens to match # enough that it's worth doing parallel runs, few enough that it # completes fairly quickly, includes both shell and Python scripts, and #
