An example application to implement unit and integration tests using test database

Introduction

A simple application for fetching and inserting musicians using Rest API to demonstrate the examples of unit test and integration test.

Requirements

• Application is developed in Python 3.9
• You can install the packages using the requirements.txt file.

pip install -r requirements.txt

How to Use

The purpose of the application is to show how to develop tests. So, to run the application locally, you need to setup a database instance and implement an endpoint for the external musician client.

To run all tests

pytest test

To run only unit tests

pytest test/ -k 'test and not integration'

To run only integration tests

pytest test/ -k 'integration'

Technologies used

• FastAPI and uvicorn for Rest API
• unittest for assertions and mocks
• testcontainers to initialize local-database for integration tests
• Flask for MockServer
• pandas for all dataframe operations
• psycopg2 to create a connection
