Tests should be run using subunitrun if possible, declared in tests.py via planpythontestsuite(), not planoldpythontestsuite() However, in general, unless already related to or derived from other tests, new tests should be added in Samba Tests are scattered around the code. The framework will assert that directory is empty when the test is done. (result, out, err) = nsubcmd("fsmo", "transfer",ĭescend from this class, so the self.tempdir attribute is available with a temporary directory. This example from source4/torture/drs/python/fsmo.py shows how to run an authenticated subcommand without forcing a new kinit:Ĭcache_name = self.get_creds_ccache_name()Ĭmd_line_auth = "-krb5-ccache=%s" % ccache_name The runcmd() and runsubcmd() methods allows testing of a samba-tool command in the same process, which also allows the use of To avoid a fork()/exec() of python from python, use Samba-tool is a special case, as it is written in python. Use self.check_run or self.check_output self.check_run("ndrdump samr samr_CreateUser in %s" % (self.data_path("samr-CreateUser-in.dat"))) PYTHONPATH=bin/python pydoc Ī pattern like this is typical for passing credentials to a subprocessĬmd_line_auth = "-U%s/%s%%%s" % (creds.get_domain(),Ĭreds.get_username(), creds.get_password()) You can explore the methods provided using pydoc: Samba's subclass, provides additional helper routines such as env_loadparm() This provides helpful routines such as assertTrue() etc, which provide a cosnsitent pattern in the tests. Python unittest.TestCase is the standard basis on which all of Samba's python based tests should be written. Writing Python Tests for Samba unittest.TestCase Likewise LDAP is easily accessed via LDB. If the protocol under test is DCERPC, then PIDL will have already auto-generated Python bindings. Python provides exceptions and early returns, ensuring that subsequent code doesn't run after prerequisite checks have failed, many helper functions as well as setUp() and tearDown() routines allowing unit tests to be easily built. Samba provides extensive Python bindings and test infrastructure, so if possible please write tests in Python as a first choice. 4.1 AttributeError: 'module' object has no attribute 'foo'.2.4.1 Obtaining credentials for a sub process. ![]()
