I also have a problem with including whole directory of files to test cases. Tests in

test_end_to_end.py

use files from

_input

directory I have it structured this way:

tests
|---_input
   |---file1.csv
   |---file2.csv
|--- test_end_to_end.py
|--- BUILD

And BUILD file looks like this

python_sources()

python_tests(
    name = "tests0",
)

files(
    name = "input",
    sources = [
        "_input/*",
    ],
)

And unfortunately this do not work. How should I modify my BUILD file?

Add a dependency on your input files from your python tests target:

python_tests(..., dependencies=[":input"])

Yep, Pants doesn't currently infer dependencies on resources/files , so you have to add them manually as @curved-television-6568 mentioned

There’s an example under the

files

section as well, covering your use case.
