noseapp 1.0.3

Framework for test development

Installation

pip install noseapp

About

This is framework for test development with complex logic based on nose library

background Initialization:

application -> extensions -> suites -> test cases

flexibility and control:

• application is only one service point

• require extensions for test case through suite initialization

• opportunity set default require on your base suite class

• support nose plugins (noseapp.AppPlugin)

• creation of application configuration

• before, after callbacks on base application class

implementation by steps for test case:

• memorized steps for exception info

• before, finalize callbacks on base test case class

• interactive debug mode

• parametrize step flow

asynchrony:

• multiprocessing

• threading

• gevent event loop

Quick start

app.py:

from random import randint

from noseapp import NoseApp

class ExampleExtesion(object):

  name = 'rand'

  def __init__(self, a, b):
    self._a = a
    self._b = b

  def get_random(self):
    return randint(self._a, self._b)

class MyTestApplication(NoseApp):

    def initialize(self):
      self.setup_example_ex()
      self.setup_case_settings()

    def setup_example_ex(self):
      self.shared_extension(
        cls=ExampleExtesion,
        args=(1, 1000),
      )

    def setup_case_settings():
      settings = {
        'interactiv_mode': True # may be False :)
      }

      self.shared_data('settings', settings)


def create_app(config=None, argv=None, plugins=None):
  return MyTestApplication(
    config=config, argv=argv, plugins=plugins,
  )

# create your app plagin
#
# from noseapp import AppPlugin
#
# class MyAppPlugin(AppPlugin):
#
#     name = 'my-app-plugin'
#
#     def ...(self):
#         self.app....
#
# app = create_app(plugins=[MyAppPlugin()], argv=['--with-my-app-plugin'])


# use config module for configuration in your application
#
# app = create_app(config='etc.base')
# or
# app = create_app(config='/home/user/projects/example/etc/base.py')
#
# use config property inside application class

example_suite.py:

from noseapp import Suite
from noseapp import TestCase
from noseapp.case import step
from noseapp import ScreenPlayCase


suite = Suite(__name__, require=['rand', 'settings'])


# create your suite class and use default require
#
# class MySuite(Suite):
#     DEFAULT_REQUIRE = ['settings']


@suite.register
class BasicExampleCase(TestCase):

  rand = None  # from MyTestApplication.setup_example_ex

  def test(self):
    rand_int = self.rend.get_random()
    self.assertGreater(rand_int, 0)


@suite.register
class StepByStepCase(ScreenPlayCase):

  settings = None  # from MyTestApplication.setup_case_settings

  def setUp(self):
    self.USE_PROMPT = self.settings['interactive_mode']

  @step(1, 'step description')
  def step_one(self):
    rand_int = self.rend.get_random()
    self.assertGreater(rand_int, 0)

  @step(2, 'description')
  def ...

runner.py:

from .app import create_app


if __name__ == '__main__':
  app = create_app()

  from .example_suite import suite
  app.register_suite(suite)
  # or
  # app.register_suites([suite])
  # or
  # app.load_suites(path_to_dir)

  app.run()

Usage noseapp runners

With multiprocessing:

• processes: runner.py –app-processes 2 (one suite === one process)

• processes and threads: runner.py –app-processes 4 –threads 2 (one suite == one process, one test == one thread)

• threads only: runner.py –threads 2 (one suite == one thread)

With gevent:

• runner.py –gevent 4 (one suite == one greenlet)

• runner.py –gevent 4 –greenlets 2 (one suite == one greenlet, one test == one greenlet)

Creating your own extensions

You will can create extensions for nose app as independent library. Usage redirect imports from noseapp.ext

Example:

# from your lib
from noseapp_my_ext import Extension
# With redirect import
from noseapp.ext.my_ext import Extension

Good luck and easy testing!
