Question

For our setup we re incorporating unittest in the build phase of our ci cd pipeline So that it won t deploy it to the cloud unless the test passes in Azure devops I d like to be able to run unittest on singular tasks and not start a flow run but when running ```import unittest from tasks import address matching as am from prefect import flow task class TestDatahandling unittest TestCase def test tilslutning forsyning self am address matching if name == main unittest main ``` I get following error message ```ERROR test tilslutning forsyning main TestDatahandling Traceback most recent call last File c Users nho Desktop git Prefect etl geoserver tilslutning forsyning test py line 9 in test tilslutning forsyning am address matching File C Users nho AppData Local Programs Python Python310 lib site packages prefect tasks py line 353 in call return enter task run engine File C Users nho AppData Local Programs Python Python310 lib site packages prefect engine py line 674 in enter task run engine raise RuntimeError RuntimeError Tasks cannot be run outside of a flow To call the underlying task function outside of a flow use `task fn ` ``` Two questions 1 What would the syntax for task fn in my example be I can t get it to run 2 Are there better ways or best practices of running tests on flows or does this setup seems okay

Khuyen Tran · Answer

Have you tried `am address matching fn `

Khuyen Tran · Answer

I assume `am` is a class right

Nic · Answer

am is the imported module from the task file

Khuyen Tran · Answer

and `am address matching` is a task

Nic · Answer

Yes that s right

Nic · Answer

< Khuyen Tran> am is the address matching py file so it refers to the address matching task in the file of the same name In my flow it s called like so ``` flow def tilslutning forsyning tilslutning matched forsyning matched = am address matching am write to database tilslutning matched connection obligation am write to database forsyning matched heating supply network ``` However i aim to test the tasks before deploy wanting to call singular tasks in the test file but without running a flow so i don t clock up the ui with test runs in

It works with your code plus disabling the logger ```import unittest from tasks import address matching as am from prefect import task from prefect logging import disable run logger class TestDatahandling unittest TestCase def test tilslutning forsyning self with disable run logger am address matching fn if name == main unittest main ```
