Io FinNet code example

About

This repo contains a example code to facilitate in the interview process.

The code should be deployable locally.

We expect the candidate to follow the instructions carefully, write some good automated tests to cover the expected functionality and to highlight any issues found along the way. This is a white-box testing exercise and you have full access to the code for reference.

Built With

• typescript - Typed language for application-scale

JavaScript.

• serverless - SDK for building, deploying and managing

serverless cloud services.

• cucumber.js - Tool for running automated tests

written in plain language.

Getting Started

Prerequisites

1. Install Serverless

npm -g install [email protected]

2. Install Node Modules

npm i

2. Deploy locally

serverless offline

Running offline itnegration tests

1. Run local integration tests

npm run test:offline

Instructions for the candidate

We would like the candidate to complete the following exercise.

1. Clone the repo and deploy the lambda locally (Instructions above)

2. Then it would be wise to test this lambda is working correctly using a http client tool such as POSTMAN (Requirements below).

3. We would then like the candidate to write some working automation tests to test the lambda functionality.

-- At this point, we invite the candidate to use any libraries/technologies they wish to test the lambda function as per the requirements

-- We have a basic one step passing scenario running in spec/cucumber/example.steps.ts to help you get started.

4. We have defined the lambda functionality in the Requirements section but it must be noted that some functionality may deviate from the requirements. If this is the case then please let us know what you find!
5. Finally, please send your solution back to Io FinNet in the form of a branch/Packaged solution so that we can access your solution and run your tests.

Requirements (How should the lamda work)

1. The lambda function once deployed should have two functioning endpoints (the output of serverless offline will specify the url)

• http://localhost:3000/loginaction

• http://localhost:3000/sumaction

The 'loginaction' endpoint requires the user to authenticate with a username and password. Construct a POST request with the following two headers.

username: bob

password: P@55w0rd

On successful authentication, you will receive a 200 http response and you will also be returned a token which can be used later.

On unsuccessful authentication, you will receive a 401 http response.

The 'sumaction' endpoint will simply SUM the value of two numerical inputs in the form of a JSON Object in the body. The two JSON attributes are

first: <first_numerical_value>

second: <second_numerival_value>

To use this endpoint, you must add the value of the token into the request header that was returned from the 'loginaction' endpoint. The header value should look like this

token: <token_value_that_is_returned>

Upon successful authentication and execution of the 'sumaction' endpoint, you will be returned with a 200 http response and the summed value of the two provided numbers. Example 2+2. Result will = 4.

Non-numerical values will return null after being summed.
