testing [[testing]]

nose is abandoned

pytest is the best apparently [[pytest]]

• uses the built in assert

  assert 1 == 1, 'This is my error message, which is optional'
  

• parameterized tests

• fixtures: These aren’t the setup/teardown fixtures (per-se), but more like dependency injection (and are incredibly useful). You can even inject a fixture into a fixture (say you need to log in a user, but you need an HTTP client for it to work, you probably use that client elsewhere so DRY it up):

• markers: Easy way to categorize tests (and coincidentally run only those groups)

  @pytest.mark.slow
  def test_slow_running_thing():
      time.sleep(500)
  

• parallel execution via xdist

logging

simple

import logging
logging.basicConfig(level=logging.INFO) # apparently callin basicconfig at least one is important
logging.exception('Caught an error' + str(e))

use logzero for nice colored logs

json [[json]]

json.dump(jobj, stdout, indent=4, sort_keys=True, ensure_ascii=False)

You don't need Pylint if you're using flake8

hmm
