This repository includes the following:

• Scripts

Setup

How to setup your environment

• Setup a virtual environment using the virtualenv tool to create an environment specific to this project

    virtualenv fib-env
  

• Recreate the enviroment using the requirements.txt file

    pip install -r requirements.txt
  

How to run the REST API application

The REST API is run by running the following file:

fibonacci/api/fibonacci_api.py

This will make the REST API available at the following endpoint:

http://127.0.0.1:5000/ 

The Fibonacci function provided on the REST API can be called using the following endpoint. The parameter specifies the number of items in the Fibonacci series to return

http://127.0.0.1:5000/fibonacci/5    

How to run the tests

To run the unit tests

pytest tests/test_fibonacci.py

To run the integration tests

Note: The integration tests require the REST API application to be running and serving requests in order for these tests to pass.

pytest tests/integration/test_fibonacci_functions.py

To run ALL the tests (unit tests + integration tests)

pytest

Future

Further improvements

• Use a cache to store values already calculated rather than re-calculating them. (NOW IMPLEMENTED)
• Use pytest parametrization in unit test to give more test coverage and test corner cases. (NOW IMPLEMENTED)
