  2. Ensure that the database is in a known state before each test runs, and verify the state after the run using assertions logic.

Does unit test test data in database?

SQL unit testing is a testing method which allows us to test the smallest, atomic programmable part of a database object. SQL unit testing plays a key role in the modern database development cycle because it allows us to test individual parts of the database objects work as expected.

Which is better – pytest or unittest? Although both the frameworks are great for performing testing in python, pytest is easier to work with. The code in pytest is simple, compact, and efficient. For unittest, we will have to import modules, create a class and define the testing functions within that class.

Should you mock a database?

The purpose of unit testing is to verify the database-related code works and mocking the database would hinder the test. Mocking does indeed become useful when testing the business code. You can mock your database calls to return test data and verify the behavior of business logic in those circumstances.

Can you combine pytest and unittest?

pytest supports running Python unittest -based tests out of the box. It’s meant for leveraging existing unittest -based test suites to use pytest as a test runner and also allow to incrementally adapt the test suite to take full advantage of pytest’s features.
