can you revert this please.

I ran git ls-tree -l HEAD and verified the repository structure. It appears that the examples symlink was not intentionally modified. My recent changes were limited to updating b_mongodb.py, persisters.rst, pyproject.toml, and persisters.yml.

Sorry, I apologize for missing this earlier, but we use pytest and not unittest.
This shouldn't be a big change to get it to work. You'll just need to use a pytest fixture for the persister. Do you need more pointers here, or can you handle this yourself?

i dont know weather i did it as required. help me if it is not correct

Close - can you rename the file to test_b_mongodb.py please? that's the pytest convention. test_NAME_OF_MODULE.py.
Otherwise we will need to set up the test environment to install mongodb for the test to actually pass.
Why don't we try adjusting part of python-package.yml in .github/workflows to be something like this:
test:
runs-on: ubuntu-latest
strategy:
fail-fast: false
matrix:
python-version: ['3.9', '3.10', '3.11', '3.12']
steps:
- uses: actions/checkout@v3
- name: Set up Python ${{ matrix.python-version }}
uses: actions/setup-python@v3
with:
python-version: ${{ matrix.python-version }}
- name: Install dependencies
run: |
python -m pip install -e ".[tests,tracking-client]"
- name: Run tests
run: |
python -m pytest tests --ignore=tests/integrations/persisters
test-persister-dbs:
runs-on: ubuntu-latest
services:
mongodb:
image: mongo:7.0

- 27017:27017
postgres:
image: postgres:15
ports:
- 5432:5432
redis:
image: redis:7

strategy:

run: |
python -m pip install -e ".[tests,tracking-client]"
- name: Run tests
run: |
python -m pytest tests/integrations/persisters/
Can you add that please?

I did that, please let me know whether it was correct or not.

I'll merge this tomorrow my time -- thanks @NandaniThakur ! |
As this was my first open source, It was quite fun & exciting to do. thank you for your guidance and help in completing this. |
This PR adds a new MongoDB persister to the project, allowing state data to be saved and loaded from a MongoDB database. The implementation follows the existing structure of the Redis persister for consistency.
Fixes #208.
Changes
How I tested this
Created unit tests in test_mongodb_persister.py to verify the correct functionality of save, load, and list_app_ids methods.
Mocked MongoDB interactions to ensure tests do not depend on a live MongoDB instance.
Notes
Updated created_at to use timezone-aware datetime objects.
