How to use

By default primary key is 'uuid', but you can set another field as primary key and function to generate value, for example:

import uuid


db = Session(primary_key="uuid", primary_key_generate=lambda: str(uuid.uuid4()))

A simple example how to use it in flask:

import unittest
from app import flask_app
from sqlalchemy_mock import Session
from models import Model


class TestCase(unittest.TestCase):
    @classmethod
    def setUp(cls):
        cls.app = flask_app.test_client()
        cls.db = Session()

    def test(self):
        row = Model(field1="value1", field2="value2", field3="value3")
        self.db.add(row)
        self.db.commit()

        with self.db.mock_session():
            response = self.app.get(f"/get/model/object/{row.uuid}")
            self.assertEqual(response.json["field1"], row.field1)

Runinng unittests

To run unittests use command:

python -m unittest
