5.1 Unit & integration tests

[K0nkere]

As soon as I am creating unit tests for the prediction service its need open a new VSCode window choosing /project/prediction_service/ as start folder and create tests folder in it.

Launching pipenv shell and its need to add pytest as a dev package pipenv install --dev pytest

which python > path to python > CTRL+SHIFT+P and Input new Interpreter > Select Interpreter There is a convention for naming test files so its need to create two files in the tests folder __init__.py - init file test_predict.py - file that contains unit tests !!! the name of folder that contain tests == tests is obligatory and important !!! scripts name in format test_***.py is important !!!

When we !!! clone the repo and install the pipenv from Pipfile !!! via pipenv install if we want to install all --dev dependences from it its need to run pipenv install --dev lib1 lib2 lib3 - for the development purposes like tests, linting, black and etc

Better to do it at start example pipenv install -r requirements.txt --dev deepdiff --python=3.9

How to

description of os.path functions

• take absolute path to file - can feed it to some read functions

  from pathlib import Path
  path = Path(__file__).resolve()

• take absolute path to parent folder of current script_file

  from pathlib import Path
  path = Path(__file__).parent

• take absolute path to pre-parent folder of script-file

  path_to_script = os.path.split(__file__)[0]
  pre_parent = os.path.split(path_to_script)[0]
