From a8dcad9ac62bb1d2a4f7489960395bad6cac9382 Mon Sep 17 00:00:00 2001 From: Scott Moser Date: Wed, 5 Sep 2018 16:02:25 +0000 Subject: tests: Disallow use of util.subp except for where needed. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In many cases, cloud-init uses 'util.subp' to run a subprocess. This is not really desirable in our unit tests as it makes the tests dependent upon existance of those utilities. The change here is to modify the base test case class (CiTestCase) to raise exception any time subp is called. Then, fix all callers. For cases where subp is necessary or actually desired, we can use it via   a.) context hander CiTestCase.allow_subp(value)   b.) class level self.allowed_subp = value Both cases the value is a list of acceptable executable names that will be called (essentially argv[0]). Some cleanups in AltCloud were done as the code was being updated. --- tests/unittests/test_handler/test_handler_apt_source_v3.py | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) (limited to 'tests/unittests/test_handler/test_handler_apt_source_v3.py') diff --git a/tests/unittests/test_handler/test_handler_apt_source_v3.py b/tests/unittests/test_handler/test_handler_apt_source_v3.py index 7a64c230..a81c67c7 100644 --- a/tests/unittests/test_handler/test_handler_apt_source_v3.py +++ b/tests/unittests/test_handler/test_handler_apt_source_v3.py @@ -48,6 +48,10 @@ ADD_APT_REPO_MATCH = r"^[\w-]+:\w" TARGET = None +MOCK_LSB_RELEASE_DATA = { + 'id': 'Ubuntu', 'description': 'Ubuntu 18.04.1 LTS', + 'release': '18.04', 'codename': 'bionic'} + class TestAptSourceConfig(t_help.FilesystemMockingTestCase): """TestAptSourceConfig @@ -64,6 +68,9 @@ class TestAptSourceConfig(t_help.FilesystemMockingTestCase): self.aptlistfile3 = os.path.join(self.tmp, "single-deb3.list") self.join = os.path.join self.matcher = re.compile(ADD_APT_REPO_MATCH).search + self.add_patch( + 'cloudinit.config.cc_apt_configure.util.lsb_release', + 'm_lsb_release', return_value=MOCK_LSB_RELEASE_DATA.copy()) @staticmethod def _add_apt_sources(*args, **kwargs): @@ -76,7 +83,7 @@ class TestAptSourceConfig(t_help.FilesystemMockingTestCase): Get the most basic default mrror and release info to be used in tests """ params = {} - params['RELEASE'] = util.lsb_release()['codename'] + params['RELEASE'] = MOCK_LSB_RELEASE_DATA['release'] arch = 'amd64' params['MIRROR'] = cc_apt_configure.\ get_default_mirrors(arch)["PRIMARY"] @@ -464,7 +471,7 @@ class TestAptSourceConfig(t_help.FilesystemMockingTestCase): 'uri': 'http://testsec.ubuntu.com/%s/' % component}]} post = ("%s_dists_%s-updates_InRelease" % - (component, util.lsb_release()['codename'])) + (component, MOCK_LSB_RELEASE_DATA['codename'])) fromfn = ("%s/%s_%s" % (pre, archive, post)) tofn = ("%s/test.ubuntu.com_%s" % (pre, post)) -- cgit v1.2.3 From 37078046cb191234982d95ad4876af4ed8f862f4 Mon Sep 17 00:00:00 2001 From: Robert Schweikert Date: Mon, 17 Sep 2018 11:37:27 +0000 Subject: tests: Add mock for util.get_hostname.
