Hi Benji
Betreff: [Zope-dev] Test runner: layers, subprocesses, and tear down
[... ]
#2 will add some process start-up overhead, but it'll only be one more process than is already started (and any reasonably-sized test corpus already starts several processes for each test run). The one exception is for running with -D or with a pdb.set_trace() embedded in the code under test. For that case we need a switch to say "don't start any subprocesses at all", I suspect that will be spelled -j0.
That's a very important point. I often use pdb if I write tests.
For motivation, some speed comparisons: running a particular test suite with 3876 tests (mostly doctests, and mostly functional) without the patch takes 6 minutes, 42 seconds; my branch runs the same tests in 3 minutes and 22 seconds (give or take) on a dual-core box with 3 simultaneous subprocesses.
Yeah, great! Regards Roger Ineichen
