Hi everyone, I'm trying to write a unit test for a Prefect flow that uses a task decorated with

@task

from Prefect. Here's a summary of my setup and the issues I'm facing: Setup: • I have a Prefect flow (

prefect_example_flow

) that imports and uses a task (

get_flow1_target_task

) decorated with

@task

. • I want to mock

get_flow1_target_task

to test the flow without invoking the real logic. Attempts So Far: 1. Patching the Task Directly: I used

@patch('path.to.get_flow1_target_task')

to replace the task with a mock. However, the real method still gets called during the test. 2. Patching

run()

Method: Tried

@patch.object(get_flow1_target_task, 'run')

to mock the

run()

method of the task object, but encountered

AttributeError

, indicating that

Task

does not have the

run

attribute. 3. Side Effects and Return Values: Attempted using

side_effect

on the mock to simulate task behavior based on input parameters, but it didn't resolve the issue. 4. Path Verification: Double-checked that the import paths and

@patch

paths matched correctly where the task is used in the flow. Current Issue: Despite these efforts, the actual

get_flow1_target_task

method is still being executed in the unit test, and mocking does not seem to apply. Request for Help: Does anyone have experience successfully mocking Prefect

@task

decorated methods in unit tests or know of any special considerations when mocking Prefect tasks? Any guidance or alternative approaches would be greatly appreciated!

From a "risk-of-breaking" perspective, I don't think I'd even try put two "does a bunch of complicated stuff" type decorators on the same function. Can you try having one function with the

@task

decorator which calls a separate function that has the

@patch

decorator?
