Hi me again. Just hit another issue (highly likely me not configuring things right) Have the following Shared/tests/helpers/somefile.py Shared/tests/common/folder/myfile_test.py-> from helpers.somefile import function Shared/common/folder/myfile.py When i run pants test it throws NoModule exception for ‘helpers’ have a configured something wrong here. The tests and folder all have init file and have run tailor to ensure it generates the build file. Thanks in advance

Source roots are key here: https://www.pantsbuild.org/docs/source-roots#what-are-source-roots What does

./pants roots

say?

./pants roots . lambdas/get_session shared

@abundant-analyst-12845 so you want `Shared/tests`to be a source root to be able to import

Shared/tests/helpers/somefile.py

as

helpers.somefile

-does that make sense?

my source root looks like this

[source]
root_patterns = [
    "/lambdas/*",
    "/shared",
    # for conftest
    "/",
]

so thought tests would be able to picked up as well

Please try explicitly adding

/shared/tests

and report back and we can work from there to make sure you understand why this is needed

@abundant-analyst-12845, what is the full path of the

shared/session.py

you expect to be found for import? Whatver the answer, the prefix must be a source root.

so here is the structure

@abundant-analyst-12845 instead of feeding you answers I'd rather get you to learn the concept. Can you use the algorithm I described to solve the issue or is the algorithm confusing or is it not working?

so I am not sure if I understood the concept but I was able to fix by mocking

correctly

i was mocking using

patch

using where the Class/Module was defined as opposed to where it was used.

Aha, ok so

shared.session

is not 1st party code; i.e.: you have no answer for what the full path of

shared/session.py

is because its code in some 3rdparty dependency? If so, then this makes sense, the algorithm I described is for 1st party code.

The full path of that from the root of the project is shared/shared/session/adaptor.py

Ok, and what does

./pants roots

say right now? Does it include

shared

still?

Sho am treating shared (first part) as namespace where as shared/shared as the project. And roots still shows shared as a root

Ok. Well without access to this repo its hard for me to say what's going on here.
