PERTAIN_TODomain

PERTAIN_TOProblem

Pytest async tests for a FastAPI app fail with RuntimeError: “Task got Future attached to a different loop” when interacting with the database via SQLAlchemy.

PERTAIN_TOSolution

I found a trick forking the jvm, below sbt config — for unit tests. Tension: must be the same idea for classic run (fork + javaOptions).

PERTAIN_TOSolution

@ExtendWith({ MockitoExtension.class, ApplicationExtension.class }) — To use TestFX to test a JavaFX application. Tension: how do you do both at the same time? Outcome: it works for this case.

PERTAIN_TOProblem

this configuration is only about the surefire plugin, used to run tests — I'm working on a user-related service that handles personal information. Tension: My senior mentioned that since this is a user service dealing with personal data, I need to make sure that the configuration above doesn't: Interfere with anything outside the test scope, or Pose any security risks to the service or user data. Outcome: it would have no impact on the production JVM instance your service uses.

PERTAIN_TOProblem

if the `userService` field is removed, the dependency is set to null, which causes a `NullPointerException` when the test runs — In my Spring Boot app, I have some tests that look like this. Tension: I don't need to mock or verify any `userService` methods, so IntelliJ marks this as an unused field.

You could achieve this with constructor injection. — In your service, make sure the dependencies are injected using the constructor. Tension: what I'd prefer is to not have to declare this field at all. Outcome: private InviteService inviteService = new InviteService(emailSendingService, userService);.

PERTAIN_TOProblem

IntelliJ suggests importing the one from `java.lang.reflect`. — Make sure you import `Executable` from the right source. Tension: the `FunctionalInterface` error comes from there. Outcome: This should now do the job.

PERTAIN_TOSolution

Make sure you import `Executable` from the right source. Tension: IntelliJ suggests importing the one from `java.lang.reflect`. Outcome: Assertions.assertAll(exec);.

PERTAIN_TOSolution

Run ORM writes in a sync function wrapped with asgiref.sync_to_async and explicitly close the Django database connection (e.g., connection.close()) after the bulk/create operation so teardown can complete.
