class oioioi.problems.tests.utilities.AssertContainsOnlyMixin

assert_contains_only(response, allowed_values)

class oioioi.problems.tests.utilities.TestProblemController(problem)

Bases: oioioi.problems.controllers.ProblemController

Defines rules for handling specific problem.

Every method should:

• be called from contest controller

• or be specific for problems that this controller controls

Please note that a global problem instance exists for each problem. That problem instance has no contest (contest is None), so methods can’t be overridden by a contest controller which means they behave in a default way.

__test__ = False

abstract fill_evaluation_environ(environ, submission, **kwargs)

Fills a minimal environment with evaluation receipt and other values required by the evaluation machinery.

Passed environ should already contain entries for the actiual data to be judged (for example the source file to evaluate).

Details on which keys need to be present should be specified by particular subclasses.

As the result, environ will be filled at least with a suitable evaluation recipe.

exception oioioi.problems.tests.utilities.DummyPackageException

Bases: Exception

Common base class for all non-exit exceptions.

class oioioi.problems.tests.utilities.DummyPackageBackend

Bases: oioioi.problems.package.ProblemPackageBackend

A class which manages problem packages.

The main functionality is extracting archives with problem statements, data, model solutions etc. and building Problem instances.

description = Dummy Package

identify(path, original_filename=None)

Checks if the backend is suitable for processing the specified problem package.

Parameters

• path – a path to the processed problem package

• original_filename – the name of the package specified by the

uploading user.

Returns True if the backend can handle the specified problem package file.

get_short_name(path, original_filename=None)

Returns the problem’s short name.

Parameters

• path – a path to the processed problem package

• original_filename – the name of the package specified by the

uploading user.

unpack(env)

Processes a package, creating a new Problem or updating an existing one.

This function will be called either from unpackmgr_job() (Celery task) or from simple_unpack() (e.g. when a problem is added from a command line).

Used env keys:

package_id: an id of the ProblemPackage instance with the package file to unpack.

Produced env keys:

problem_id: an id of the Problem instance representing the created or modified problem.

pack(problem)

Creates a package from problem, returns a django.http.HttpResponse instance.

Should raise NotImplementedError if creating packages is not supported.

oioioi.problems.tests.utilities.dummy_handler(env)

class oioioi.problems.tests.utilities.DummySource

Bases: oioioi.problems.problem_sources.UploadedPackageSource

create_env(*args, **kwargs)

Creates an environment which will be later passed to unpackmgr_job().

class oioioi.problems.tests.utilities.DummyContestController(contest)

Bases: oioioi.programs.controllers.ProgrammingContestController

Contains the contest logic and rules.

This is the computerized implementation of the contest’s official rules.
