noseapp extension for linux daemon testing

Installation

pip install noseapp_daemon

Create Runner

from noseapp.ext.daemon import DaemonRunner

class MyPythonDaemon(DaemonRunner):

    CMD_PREFIX = 'python'
    DAEMON_BIN = '/path/to/daemon/daemon.py'


my_daemon = MyPythonDaemon('my_daemon')
my_daemon.add_cmd_option('-c', '/path/to/config')
my_daemon.start()

Create daemon plugin

from noseapp.ext.daemon import DaemonPlugin


class MyPythonDaemonPlugin(DaemonPlugin):

    def init(self, daemon):
        # do something

    def before_start(self, daemon):
        # do something

    def after_start(self, daemon):
        # do something

    def before_stop(self, daemon):
        # do something

    def after_stop(self, daemon):
        # do something


my_daemon = MyPythonDaemon('my_daemon', plugin=MyPythonDaemonPlugin())

Create Service

from noseapp.ext.daemon import DaemonService

class MyDaemonService(DaemonService):

  name = 'my_service'

  def setup(self):
      self.daemon = MyPythonDaemon('my_daemon')

  def start(self):
      self.daemon.start()

  def stop(self):
      self.daemon.stop()

  ...


service = MyDaemonService()
service.start()
service.restart()

Create Management

from noseapp.ext.daemon import DaemonManagement

management = DaemonManagement(app)
management.add_daemon(
    MyPythonDaemon('my_daemon', plugin=MyPythonDaemonPlugin()),
)
daemon = management.daemon('my_daemon')

def error_handler(daemon, e):
    # do something

with management.checkout_daemon('my_daemon', except_exc=Exception, error_handler=error_handler) as daemon:
    daemon.restart()

management.add_service(MyDaemonService())
service = management.service('my_service')

# to install as extension
management.install(app)

suite = Suite(__name__, require=['my_daemon'])

# management.stop_all()
# management.stop_daemons()
# management.stop_services()
# management.restart_all()
# etc ...
