Summary

The project is intended to emulate regular Sugar client behaviour to help, e.g., with testing Sugar Server Kit components and Sugar Server Kit based solutions.

Library

It is useful for python code that tests, e.g., the school server internals.

See sugar-server integration tests for examples.

System testing scenarios

In this mode, the sugar-unit application tries to behave as a regular host with sugar launched on it, including anti-thief features specific only for XO laptops.

Scenario files

Regular use involves writing scenarios—python scripts that need to be launched by the sugar-unit program, i.e., such files need to have headers (you need to have the path to the source sugar-unit file in the PATH environment variable): 

#!/bin/env sugar-unit

Scenario files should classes inherited from sugar_unit.tests.Case that are regular unittest.TestCase classes.

Actions

The building blocks of sugar-unit scenarios are actions. Actions are objects of classes inherited from sugar_unit.context.Action. Action classes represent one particular aspect of some sugar client behaviour, e.g., activation or backup.

A simple scenario looks like: 

import os
from sugar_unit import tests, actions

class Test(tests.Case):

   def test_XO_walkthrough(self):
       self.assertAction(actions.Activation)
       self.assertAction(actions.Registration, force=True)

       ds_path = self.bot.store('foo', 'bar')
       self.assertAction(actions.Backup)

       os.unlink(ds_path)
       self.assertAction(actions.Restore)
       assert exists(ds_path)
       assert file(ds_path).read() == 'bar'

       self.assertAction(actions.Presence)

Launch

Useful command-line arguments.

nick

While working, sugar-unit will behave on behalf of only one Sugar user. By default, user's nick is test, but it might be changed using the --nick command-line argument. The XO serial number and UUID will be calculated basing on nickname. Default nickname is also hardcoded in sugar-server sources, so, sugar-server will always have a lease for this nick. For non-default nicknames, the corresponding leases need to be registered in sugar-server, getting SN and UUID from sugar-unit id output.

profile-dir

sugar-unit will create a directory for Sugar profile, i.e., an analog of profile directories in ~/.sugar. By default, profile directory will be created in the current one using nickname as a directory name. It might be changed using the --profile-dir command-line argument.

lease-key

To verify leases gotten from the sugar-server, sugar-unit should know the lease public key, the default one (which sugar-server uses for default lease) comes with sugar-unit sources. For non-default leases, use the --lease-key command-line argument to specify the key path.

api-url

By default, sugar-unit will look for default, hardcoded in Sugar Shell sources, API url, http://schoolserver:8000. But, it is possible to specify any other, using the --api-url command-line argument.

Getting involved

  • Report on bugs.
  • Read the HACKING file to know how to contribute with code.
