Unable to run python tests - No module named beat.beat

I am unable to run python tests for packetbeat or any other beats.
Here's what I've done:

  1. in the packetbeat dir i ran make python-dev
  2. then navigated to the tests/system folder and ran nosetests -x -v. Getting the following error:
❯ nosetests -x -v
Failure: ImportError (No module named beat.beat) ... ERROR

======================================================================
ERROR: Failure: ImportError (No module named beat.beat)
----------------------------------------------------------------------
Traceback (most recent call last):

    return self.importFromDir(dir_path, fqname)

    from packetbeat import BaseTest
  File "/home//Projects/beats/packetbeat/tests/system/packetbeat.py", line 5, in <module>
    from beat.beat import TestCase
ImportError: No module named beat.beat

In addition to that python code navigation does not work in either intellij or vscode for same reason:

❯ /home//Projects/beats/packetbeat/build/python-env/bin/python3 /home//Projects/beats/packetbeat/tests/system/test_0005_mysql_integration.py
Traceback (most recent call last):

    from beat.beat import TestCase
ModuleNotFoundError: No module named 'beat'

Beats is not using nosetests anymore. We have adopted pytest instead.

This is how I usually run tests:

python3 -m pytest tests/system/test_base.py --verbose

Let me know if you still have issues.

Hi

Now getting a different error -

Ran go test -c and it created packetbeat.test. Would be nice to have all of this in the documentation :frowning:
