Breakdown
1
from django.test import SimpleTestCase
Imports SimpleTestCase for unit testing without database interaction.
2
from myapp.services import format_user_notification
Imports the async utility function to be tested.
3
class AsyncNotificationTest(SimpleTestCase):
Declares a test case class inheriting from SimpleTestCase.
4
async def test_async_message_formatting(self):
Defines an asynchronous test method that can await coroutines directly.
5
result = await format_user_notification("welcome")
Awaits the asynchronous function under test to retrieve its return value.
6
self.assertEqual(result, "Welcome to the platform!")
Asserts that the asynchronous function output matches the expected string.
