[wvandeun]

Component

Python SDK

Infrahub SDK version

1.1.0

Current Behavior

You are unable to use the pytest plugin for user provided resources that use a relative import.

tests/test_resources.yml::infrahub_check__check_tag__smoke-test FAILED                                                 [100%]

========================================================== FAILURES ==========================================================

================================================== short test summary info ===================================================

===================================================== 1 failed in 0.03s ======================================================

Expected Behavior

The pytest plugin works for user provided resources that use relative imports

Steps to Reproduce

• spin up an instance of Infrahub
• create a local repository and initialize it as a repository
• create the file check_tag.py in the directory

from infrahub_sdk.checks import InfrahubCheck
from .utils import something

class MyCheck(InfrahubCheck):
    query = "check_tag"

    async def validate(self, data: dict) -> None:
        a = something()
        return

• create the file utils.py in the directory

def something() -> str:
    return "something"

• create the file check_tag.gql in the directory

query check_tag($name: String!) {
  BuiltinTag(name__value: $name) {
    edges {
      node {
	id
      }
    }
  }
}

• create the file .infrahub.yml in the directory

---
check_definitions:
  - name: check_tag
    class_name: MyCheck
    file_path: "check_tag.py"
    targets: tags
    parameters:
      name: "name__value"

• create a tests directory in the repository
• create a file tests/test_resources.yml

---
version: "1.0"
infrahub_tests:
  - resource: Check
    resource_name: check_tag
    tests:
      - name: smoke-test
        expect: PASS
        spec:
          kind: check-smoke

• in the root of the respository execute the following command

pytest -v

As part of this we should move away from the get_check_class_instance() / get_transform_class_instance() functions and instead use the general .load_class() methods as defined within the repository schema. This work should be done after #160 has been merged to avoid extra conflicts.

[~accountid:712020:ce1b5966-e028-4429-866c-40a86efdd75b] which issue to you mean by #160? Can’t find the right one, and this is a hot topic so want to see how to move it along
