Hey, am seeing something weird and wanted to see if anyone had any ideas. We're trying to structure a python package like this:

mypackage/__init__.py
mypackage/hello.py
mypackage/tests/test_hello.py

However, when we try to run the test file using pants, it complains it cannot import module

mypackage.hello

. However,

pants dependencies --transitive mypackage/tests/test_hello.py

shows all `mypackage/hello.py`'s dependencies as well, only the module itself is missing. So it seems like pants is correctly inferring that

test_hello.py

depends on

hello.py

but then not adding

hello.py

in as a dependency?

How does the test import the package? As a normal import?

Yep,

from mypackage.hello import hello_world

Yeah, that sounds like the problem. if there’s a path

/foo/bar.py

and

/foo

is a source root, then

import bar

works to load that file, not

import foo.bar
