Unit Testing vs Integration Testing

• Unit Testing:
• This a type of software testing where small unit of code is tested.
• The small unit of code is generally an individual function or class or module.
• Unit Tests are performed by Developers
• Integration Testing:
• This is the process of testing the interface between two software units or components.
• This is focused on determining the correctness of the Interface.
• In our microservices, the integration with individual service is using REST API
• Lets make changes to copy the test db for every test invocation.
• Create a constants file with database names
• make changes in the app.py the include the database path while creating flask application
• Add the copy empty database to temp location in fixture and add the new db location while create test_client for flask app.
• Refer Here for the changes done
• Refer Here for the changes made to check the specific items
• Exercise: Now create a test for the catalog brand where you perform all the steps as done it test_catalogbrand, ensure you create reusable code.
