rbtools.testing.api.transport¶

API transports for unit tests.

New in version 3.1.

Classes

URLMapTransport(url[, username, password, ...])

API transport for defining and querying URL maps of responses.

class rbtools.testing.api.transport.URLMapTransport(url, username=None, password=None, cache_location=None, in_memory_cache=False, **kwargs)[source]¶

Bases: Transport

API transport for defining and querying URL maps of responses.

This transport allows unit tests to define the URLs they want to test against, mapping URLS and HTTP methods to groups of payloads and headers, and HTTP status codes.

By default, this provides a handful of pre-built URLs:

/api/
/api/info/
/api/repositories/
/api/review-requests/

Unit tests can define any additional resources they need through the following functions:

add_item_url()
add_list_url()

Any defined URLs can be modified by changing entries anywhere in the urls dictionary. These changes will not persist to other unit tests.

API capabilities can also be changed be modifying capabilities.

If unit tests need URLs that are not already defined on this transport, it may be worth contributing helper functions to this class, in order to ensure consistency (see the implementation of add_repository_url() for details).

New in version 3.1.

api_calls¶

A list of API calls that have been made. Each is a dictionary containing:

Keys:

method (unicode) – The HTTP method.
path (unicode) – The API path, relative to the root of the server.

Type:

list of dict

cache_location¶

The cache location configured when constructing the transport or when calling enable_cache().

Type:: unicode

cache_in_memory¶

The cache-in-memory flag configured when constructing the transport or when calling enable_cache().

Type:: bool

capabilities¶

The dictionary of capabilities to simulate being returned from the API. This can be modified as needed by unit tests.

Type:: dict

list_item_payloads¶

A mapping of relative list URLs to lists of item payloads that should be returned when accessing that list resource.

Note that list resources must be registered through add_list_url().

Type:: dict

logged_in¶

Whether the user is logged in.

This will be set to True if a username and password are provided during construction, or if login() is called.

Type:: bool

login_credentials¶

A dictionary of login credentials.

This will be set to a dictionary with username and password keys if a username and password are provided during construction, or if login() is called. Otherwise it will be None.

Type:: dict

payload_factory¶

The payload factory used to construct resource object and response payloads. This can be used when calling add_item_url() or add_list_url().

Type:: rbtools.testing.api.payloads.PayloadFactory

transport_kwargs¶

Additional keyword arguments passed during construction.

Type:: dict

urls¶

The mapping of URLs to response information. This is in the following form:

urls = {
    '/api/.../[?...]': {
        '<HTTP method>': {
            'headers': {
                'Content-Type': '...',
                ...,
            },
            'http_status': ...,
            'payload': {
                'stat': '...',
                ...,
            },
        },
        ...
    },
    ...
}

Anything in this tree can be freely modified by unit tests. Changes will not persist across tests.

Type:: dict
