            Well, the solution was rather pretty trivial and rather quite ignorant of me!

            Instead of using uuid module, one must use Faker's uuid4 provider.

            But I, still wonder why using uuid module(which is created for the sole purpose of generating uuid(s)) did not work.

            Fake data for django channels unit tests
            Asked 2021-Aug-29 at 11:13

            I previously asked a question regarding this topic but finally I gave up on that because there seemed to be no way ...

            But now I really really really need to write unit tests for my django channel consumers because the application is growing larger in size and manual testing isn't efficient anymore. So I decided to ask another question and this time I'm going to do my best to explain the situation.

            The main problem is "Generating Fake Data". I'm using factory_boy and faker together in order to generate fake data for my tests. When I generate fake data, it is accessible from inside the TestCase itself but is not accessible inside the consumer. Let me show you by an example, consider the code below:

            test_consumers.py ...

            Issue: You face this data missing issue because of asynchronous calls.

            Solution: In django.test there is a test class called TransactionTestCase. By using this we can overcome that asynchronous data missing issue.

            Make following changes and you are all set to go:

            test.py

            Replace TestCase with TransactionTestCase and you are all set to go.

            Deduced attributes of a LazyAttribute using Factory Boy
            Asked 2020-Nov-19 at 10:32

            Using Factory Boy and Faker in a Django project, i would like to create deduced attributes, meaning a method from Faker returns a set of values that are dependent on each other. These values will be utilized for other attributes of the Factory Class.

            Example: The location_on_land method from faker.providers.geo returns a tuple of latitude, longitude, place name, two-letter country code and timezone (e.g. ('38.70734', '-77.02303', 'Fort Washington', 'US', 'America/New_York'). All values depend on each other, since the coordinates define the place, country, timezone, etc. Therefor i cannot use separated functions for the (lazy) attributes like faker.providers.latitude, faker.providers.longitude.

            Is it possible to somehow access the return values from the lazy attribute to use them for other deduced attributes? Is there a better way to access the return values from location_on_land to use them on the other depending attributes My Factory-Class looks like this:

            When using factory.Params, the resulting attribute is available on the first parameter on factory.LazyAttribute: the passed-in instance is a stub used to build the parameters for the actual model call.

            In your case, I'd go with the following factory.

            Note that the geo_data field is declared as a parameter (i.e not passed to the models.Origin constructor); but it is still available to other declarations on the factory.

            Answered 2020-Oct-23 at 21:29

            I'd say all of these approaches are acceptable (however, you probably don't want to mock the object you are testing like you do in test_is_fully_locked_with_no_employee_locked_mock - rather create Observation object and mock admin_locked field).

            I'm not sure if you are supposed to avoid "touching" the database - Django test runner creates a test database for each run. It is a bit slower, but in some cases that's the only way to test your code. If you can get away with in-memory object (like test_is_fully_locked_with_no_employee_locked test), it can speed up your test.

            Mock library is usually used to mock functions that, for example, make a request to external server, run heavy database query, non-deterministic and so on - that are hard to reproduce in test environment.

            Factory Boy Build JSON String from Another Factory
            Asked 2020-Jul-28 at 22:21

            I am trying to use Factory Boy in order to generate test data for my test suite. My data consists of JSON objects with a body field that contains an escaped JSON String (example below). I also included example python dataclasses and Factory Boy factories for this example data.

            Note: For this example, I am skipping the setup of fake data using Faker or the built-in fuzzers to simplify the question. In a more realistic use case, fields like eventtime, deviceid, enqueuedTime would contain rondomized values (using a fixed seed for the randomness)

            Why this happens?

            When you import a Python module (your import factory), you can then access directly what is declared in that module (e.g factory.Factory): all symbols declared in the module are automatically exported.

            However, if a nested module is not imported in its parent, you have to import it directly.

            Here, factory.Factory is available, because factory/__init__.py contains:
