node_bdd_api_tests VS chai

Git repo : https://github.com/Bharath-Kumar-S/node_bdd_api_tests/ I hope this was helpful. Please leave your feedback.

Let's configure tests with mocha, chai and sinon on Typescript in a few steps.

These options totally depend on your requirements. For example an empty hardhat option is a very basic project sample if you need more libraries, plugins or you use Typescript later, you have to add them manually. Like @nomiclabs/hardhat-waffle , [ethereum-waffle](https://www.npmjs.com/package/ethereum-waffle), chai , @nomiclabs/hardhat-ethers , ethers , [@openzeppelin/contracts](https://www.npmjs.com/package/@openzeppelin/contracts) Because, they'll allow us to interact with Ethereum and to test our contracts.

For those of you wondering what a "Chaijs" is like I was: https://github.com/chaijs/chai

> BDD / TDD assertion framework for node.js and the browser that can be paired with any testing framework.

ES6 test setup with Mocha and Chai.

It'd be hard for me to imagine what would it be like back then to write tests if it wasn't for Enzyme. Even with Enzyme, it was noticeably harder than it is today, and I still vividly remember installing and configuring in my project Mocha, Chai, Sinon, and JSDOM, to get pretty much the same tooling that today a single library - Jest - provides out of the box, while adding numerous features on top of that.

The library offers a BDD testing style and fully exploits javascript promises - the resulting tests are simple, clear and expressive. Chakram is built on node.js, mocha, chai and request.

For this example, I am using Mocha, plus Chai for its BDD expect syntax and the chai-as-promised plugin for asynchronous matchers.
