10 | 10 | # Modifying this script is tricky because it has many modes: |
|
11 | 11 | # - serial (default) vs parallel (-jN, N > 1) |
|
12 | 12 | # - no coverage (default) vs coverage (-c, -C, -s) |
|
13 | 13 | # - temp install (default) vs specific hg script (--with-hg, --local) |
|
14 | 14 | # - tests are a mix of shell scripts and Python scripts |
|
15 | 15 | # |
|
16 | 16 | # If you change this script, it is recommended that you ensure you |
|
17 | 17 | # haven't broken it by running it in various modes with a representative |
|
18 | 18 | # sample of test scripts. For example: |
|
19 | 19 | # |
|
20 | 20 | # 1) serial, no coverage, temp install: |
|
21 | 21 | # ./run-tests.py test-s* |
|
22 | 22 | # 2) serial, no coverage, local hg: |
|
23 | 23 | # ./run-tests.py --local test-s* |
|
24 | 24 | # 3) serial, coverage, temp install: |
|
25 | 25 | # ./run-tests.py -c test-s* |
|
26 | 26 | # 4) serial, coverage, local hg: |
|
27 | 27 | # ./run-tests.py -c --local test-s* # unsupported |
|
28 | 28 | # 5) parallel, no coverage, temp install: |
|
29 | 29 | # ./run-tests.py -j2 test-s* |
|
30 | 30 | # 6) parallel, no coverage, local hg: |
|
31 | 31 | # ./run-tests.py -j2 --local test-s* |
|
32 | 32 | # 7) parallel, coverage, temp install: |
|
33 | 33 | # ./run-tests.py -j2 -c test-s* # currently broken |
|
34 | 34 | # 8) parallel, coverage, local install: |
|
35 | 35 | # ./run-tests.py -j2 -c --local test-s* # unsupported (and broken) |
|
36 | 36 | # 9) parallel, custom tmp dir: |
|
37 | 37 | # ./run-tests.py -j2 --tmpdir /tmp/myhgtests |
|
38 | 38 | # |

39 | 39 | # (You could use any subset of the tests: test-s* happens to match |
|
40 | 40 | # enough that it's worth doing parallel runs, few enough that it |
|
41 | 41 | # completes fairly quickly, includes both shell and Python scripts, and |
