Consider a scenario where a function interacts with a database. How would you mock the database interactions for unit testing this function?
- Create a separate test database for unit testing
- Directly connect to the production database for testing
- Manually insert test data into the production database
- Use a mocking framework to simulate database responses
By using a mocking framework, you can simulate the behavior of the database interactions without actually accessing the database. This allows for controlled testing without the need for a real database connection, making tests faster and more reliable.
