Steps to replicate :

1. Install ganache to use as test blockchain network.
2. Change ganache port to 8545 for Metamask to catch or create a new network on Metamask. (Optional)
3. Clone the repo and install packages

git clone https://github.com/shivammutrejarug/research_gnache.git
cd research_gnache
npm install . 

4. If you haven't made changes as suggested in step 2, change the port to 7545 i.e the default ganache port in truffle-config.js
5. Deploy the contract and run tests.

truffle migrate \\this will deploy the contract on the blockchain.
truffle test \\run test cases.
