Parameters (all optional): * config: provide a `nose.config.Config`_ or other config class instance; if not provided a `nose.config.Config`_ with default values is used. * importer: provide an importer instance that implements `importFromPath`. If not provided, a `nose.importer.Importer`_ is used. * workingDir: the directory to which file and module names are relative. If not provided, assumed to be the current working directory. * selector: a selector class or instance. If a class is provided, it will be instantiated with one argument, the current config. If not provided, a `nose.selector.Selector`_ is used.
