From: Zooko O'Whielacronx Date: Thu, 22 Jan 2009 22:38:18 +0000 (-0700) Subject: setup: change test_runner to invoke "bin/tahoe" in a subprocess instead of executing... X-Git-Tag: allmydata-tahoe-1.3.0~163 X-Git-Url: https://git.rkrishnan.org/%5B/%5D%20/uri/frontends/%22doc.html/?a=commitdiff_plain;h=210da5cd9a7e7c4627ccaff1078a1249fd6963c5;p=tahoe-lafs%2Ftahoe-lafs.git setup: change test_runner to invoke "bin/tahoe" in a subprocess instead of executing runner.runner() This is necessary because loading allmydata code now depends on PYTHONPATH manipulation which is done in the "bin/tahoe" script. Unfortunately it makes test_runner slower since it launches and waits for many subprocesses. --- diff --git a/src/allmydata/test/test_runner.py b/src/allmydata/test/test_runner.py index c4b86684..ec544ac5 100644 --- a/src/allmydata/test/test_runner.py +++ b/src/allmydata/test/test_runner.py @@ -3,12 +3,14 @@ from twisted.trial import unittest from cStringIO import StringIO from twisted.python import usage, runtime -from twisted.internet import defer +from twisted.internet import defer, utils import os.path, re from allmydata.scripts import runner from allmydata.util import fileutil, pollmixin -class CreateNode(unittest.TestCase): +from allmydata.test import common_util + +class CreateNode(unittest.TestCase, common_util.SignalMixin): def workdir(self, name): basedir = os.path.join("test_runner", "CreateNode", name) fileutil.make_dirs(basedir) @@ -17,83 +19,116 @@ class CreateNode(unittest.TestCase): def test_client(self): basedir = self.workdir("test_client") c1 = os.path.join(basedir, "c1") -
