Test not found in github actions

I am trying to do an automated test.
There should be 21 tests, but github-actions can't find them for some reason.
https://github.com/duri0214/portfolio/actions/runs/4215160033/jobs/7316095166#step:3:6

manage.py is under mysite directory, so...
(Below is when I run it on my local PC)

(venv) PS D:\OneDrive\dev\portfolio\mysite> python manage.py test
  Found 21 test(s).
  Creating test database for alias 'default'...
  System check identified no issues (0 silenced).
   :
  self.client.post(reverse('vnm:likes', kwargs={'user_id': 1, 'article_id': 99}), follow=True)
  AssertionError: ObjectDoesNotExist not raised

  ======================================================================
  FAIL: test_post_click_good_button 
  (vietnam_research.tests.test_views.TestView)
  ----------------------------------------------------------------------

  OK

Anyone know a solution?
thanks

After looking at your repo (https://github.com/duri0214/portfolio) and testing it locally on my side, I found out that __init__.py was missing. Maybe, it was due to the fact that it was added in your .gitignore file which prevented its inclusion in your repo.

Here's the sample workflow that I tested it with:

name: python_test

on: workflow_dispatch

jobs:
  ci:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
      uses: actions/checkout@v3
      with:
        repository: duri0214/portfolio

    - name: Set up Python
      uses: actions/setup-python@v4
      with:
        python-version: 3.8
        cache: pip

    - name: Set up and run tests
      run: |
        python3 --version
        python3 -m venv venv
        . venv/bin/activate
        python -m pip install --upgrade pip
        python -m pip install -r requirements.txt
        cd mysite
        touch ./vietnam_research/__init__.py
        touch ./vietnam_research/tests/__init__.py
        python manage.py test        

You may observe the __init__.py being manually created in the last step.

So, you have to remove __init__.py from your .gitignore file and push those to your repo.

Apart from that, you need to cd mysite first before running the test command. Also, your tests seem to be using database and environment variables to be run successfully. So, you'll have to configure the database (if required) and set the env vars via GitHub secrets accordingly.
