The [nosetests] section can contain any command line arguments that +nosetests supports. The differences between issuing an option on the command +line and adding it to setup.cfg are: + +* In setup.cfg, the -- prefix must be excluded +* In setup.cfg, command line flags that take no arguments must be given an + argument flag (1, T or TRUE for active, 0, F or FALSE for inactive) + +Here's an example [nosetests] setup.cfg section:: + + [nosetests] + verbosity=1 + detailed-errors=1 + with-coverage=1 + cover-package=nose + debug=nose.loader + pdb=1 + pdb-failures=1 + +If you commonly run nosetests with a large number of options, using +the nosetests setuptools command and configuring with setup.cfg can +make running your tests much less tedious. (Note that the same options +and format supported in setup.cfg are supported in all other config +files, and the nosetests script will also load config files.) + +Another reason to run tests with the command is that the command will +install packages listed in your `tests_require`, as well as doing a +complete build of your package before running tests. For packages with +dependencies or that build C extensions, using the setuptools command +can be more convenient than building by hand and running the nosetests +script. + +Bootstrapping +------------- + +If you are distributing your project and want users to be able to run tests +without having to install nose themselves, add nose to the setup_requires +section of your setup():: + + setup( + # ... + setup_requires=['nose>=1.0'] + ) + +This will direct setuptools to download and activate nose during the setup +process, making the ``nosetests`` command available. + +""" +try: + from setuptools import Command +except ImportError: + Command = nosetests = None +else: + from nose.config import Config, option_blacklist, user_config_files, \ + flag, _bool + from nose.core import TestProgram + from nose.plugins import DefaultPluginManager + + + def get_user_options(parser): + """convert a optparse option list into a distutils option tuple list""" + opt_list = [] + for opt in parser.option_list: + if opt._long_opts[0][2:] in option_blacklist: + continue + long_name = opt._long_opts[0][2:] + if opt.action not in ('store_true', 'store_false'): + long_name = long_name + "=" + short_name = None + if opt._short_opts: + short_name = opt._short_opts[0][1:] + opt_list.append((long_name, short_name, opt.help or "")) + return opt_list + + + class nosetests(Command): + description = "Run unit tests using nosetests" + __config = Config(files=user_config_files(), + plugins=DefaultPluginManager()) + __parser = __config.getParser() + user_options = get_user_options(__parser) + + def initialize_options(self): + """create the member variables, but change hyphens to + underscores + """ + + self.option_to_cmds = {} + for opt in self.__parser.option_list: + cmd_name = opt._long_opts[0][2:] + option_name = cmd_name.replace('-', '_') + self.option_to_cmds[option_name] = cmd_name + setattr(self, option_name, None) + self.attr = None + + def finalize_options(self): + """nothing to do here""" + pass + + def run(self): + """ensure tests are capable of being run, then + run nose.main with a reconstructed argument list""" + if getattr(self.distribution, 'use_2to3', False): + # If we run 2to3 we can not do this inplace: + + # Ensure metadata is up-to-date + build_py = self.get_finalized_command('build_py') + build_py.inplace = 0 + build_py.run() + bpy_cmd = self.get_finalized_command("build_py") + build_path = bpy_cmd.build_lib + + # Build extensions + egg_info = self.get_finalized_command('egg_info') + egg_info.egg_base = build_path + egg_info.run() + + build_ext = self.get_finalized_command('build_ext') + build_ext.inplace = 0 + build_ext.run() + else: + self.run_command('egg_info') + + # Build extensions in-place + build_ext = self.get_finalized_command('build_ext') + build_ext.inplace = 1 + build_ext.run() + + if self.distribution.install_requires: + self.distribution.fetch_build_eggs( + self.distribution.install_requires) + if self.distribution.tests_require: + self.distribution.fetch_build_eggs( + self.distribution.tests_require) + + ei_cmd = self.get_finalized_command("egg_info") + argv = ['nosetests', '--where', ei_cmd.egg_base] + for (option_name, cmd_name) in self.option_to_cmds.items(): + if option_name in option_blacklist: + continue + value = getattr(self, option_name) + if value is not None: + argv.extend( + self.cfgToArg(option_name.replace('_', '-'), value)) + TestProgram(argv=argv, config=self.__config) + + def cfgToArg(self, optname, value): + argv = [] + long_optname = '--' + optname + opt = self.__parser.get_option(long_optname) + if opt.action in ('store_true', 'store_false'): + if not flag(value): + raise ValueError("Invalid value '%s' for '%s'" % ( + value, optname)) + if _bool(value): + argv.append(long_optname) + else: + argv.extend([long_optname, value]) + return argv |
