Blockchain Testing Tutorial – Beginners Guide

While blockchain technology is most often associated with cryptocurrencies, it is fast evolving and has the potential to affect various industries. Developers are creating innovative solutions for healthcare, insurance, shipping, finance and governance. These solutions are more often than not created using decentralised applications that run snippets of code called smart contracts.

Decentralised apps run on blockchains like Ethereum, which is a global network of devices that form something akin to a giant supercomputer. We call each of these devices nodes, and they contain an updated copy of the entire Ethereum blockchain about 1TB of data. While there are many other blockchains capable of running smart contracts, Ethereum is the most popular one with programmers and developers. As we work on more complex decentralised apps and smart contracts, they require tools to provide various functionalities for different stages of blockchain development.

Solidity is a programming language used by blockchain developers. Solc is a command-line compiler used to convert Solidity scripts into a readable format for the Ethereum Virtual Machine. Solc can create various outputs, including running simple binaries or estimating gas fees required to run a smart contract on the Ethereum Virtual Machine. There are two types of Solidity compilers, Solc and Solc-js.

Solc-js is slower than Solc, however, it enables platforms like Remix and Pragma to function. Truffle is a development environment and testing framework for Ethereum-based decentralised applications.

With Truffle, we can inject smart contracts into web apps and develop front-end dApps as well. We cannot edit smart contracts once they go live on Ethereum. Hence, developers carefully test their apps using programmes like Ganache from the Truffle Suite of blockchain development tools. Ganache is a local memory blockchain used for development and testing. The Ethereum blockchain created using Ganache simulates all the features and adds accounts with test Ether tokens. Ganache allows us to take full control of the test blockchain we create with tools like the block explorer, advanced mining controls, and blockchain log.

Drizzle is another tool from the Truffle Suite. Where Truffle works for development and Ganache for testing, Drizzle offers a collection of front-end libraries for developers. At the core of Drizzle is an Ethereum data store based on the popular React framework, Redux, that synchronises on-chain contract and transactional data. Using Drizzle we can build user interfaces that behave predictably in highly asynchronous and non-deterministic environments.

As we mentioned earlier, Ethereum is a distributed network of computers, each called nodes. In order for us to access the Ethereum blockchain, we use applications called clients. Geth, or go-ethereum, is the most popular Ethereum client in use.

We use Geth for blockchain development, transferring tokens, creating ether, writing smart contracts and exporting block history. Although it comes with built-in access to testnet Rinkeby, it also allows users to network a local cluster of nodes to create their own Ethereum network. Metamask is an Ethereum wallet accessible through a browser extension and mobile application. However, developers can also use Metamask to work on dApps right within their browser. Metamask injects web3.

Before Metamask, developers could only work on Ethereum dApps by running a full Ethereum node. With it developers can get a degree view of the Ethereum ecosystem and collect data on dApps, protocols, and tokens. Information about how services provided by existing smart contracts and applications can help developers improve the functionality of their own projects before they go live.

It can be impractical for small companies and entrepreneurs to implement a full end-to-end blockchain solution. BaaS Blockchain-as-a-Service bears similarities to SaaS and lets users reduce the operational overheads and technical complexities that come with blockchain implementation.

BaaS lets you leverage cloud-based solutions to build, host, and use decentralised apps, smart contracts, and other blockchain-based functionality. The service providers handle and manage the tasks required to keep the Blockchain functioning and maintained. Just as testing is an important step in dApp development, so is checking the code. Ethlint was initially designed to follow the Solidity style guide. However, with time it is now a customisable tool focused on style and security of smart contracts.

Before deploying a dApp developers need to make sure that their code is free from security holes. Ethlint formats and checks Solidity code for vulnerabilities and code style issues that might render a dApp useless. Remix IDE is a browser-based solution that allows developers to write smart contracts in Solidity and Vyper.

Remix fosters faster development and implementation. Also of note when working with Remix IDE is that it debugs your code as you write it. Remix IDE runs on most modern browsers and can also run while offline. Infura is another API like web3. It also comes with an intuitive dashboard with analytics on bandwidth usage, top method calls, most active times, etc. Blockchain Testnets are crucial to the development of dApps.

Testnets are where developers run their dApps before we make them live on the blockchain. Each blockchain has a unique Testnet and developers use the respective Testnet for optimal results. As mentioned with Ganache. Laracle always works on projects using a variety of the latest blockchain development tools with a team of developers who can handle front-end, back-end and user experience design.

This degree approach lets us handle the entire development process, from conceptualisation to implementation, in-house. Get in touch with us via email, call our offices or visit us in Stratford-upon-Avon for more information on blockchain development and building your blockchain solution.

Hello all, today I am going to post about a topic that I am a huge enthusiast about: Blockchain! Nowadays data is one of the most valuable product that you can own, and as we are surrounded by fake data coming from thousands of different places, it is hard to know what is trustworthy or not. It is basically the second phase of the internet. The Internet democratized the exchange of information, blockchain promises to democratize the exchange of real value. It was created in by Satashi Nakamoto, which the identity is still unknown.

Blockchain / Smart Contracts

Although blockchain started as a vehicle to bring cryptocurrency into the mainstream, a fairly new approach to blockchain technology is starting to impact many aspects of business: the enterprise blockchain. Enterprise blockchain implementations are different from the more familiar public blockchains. Scaling up to an enterprise-level places separate demands on the technology, and these new applications require updated approaches to app development and testing to ensure they deliver on their long list of promises. Blockchain technology was originally proposed in a paper by an author or authors using the pseudonym Satoshi Nakamoto. Nakamoto proposed a revolutionary approach to implementing a cryptocurrency , Bitcoin, using a trustless distributed ledger. While this new technology was a giant leap forward in distributed and decentralized storage and processing technology, Bitcoin only scratched the surface of what blockchains could really do.

As per the definition, Blockchain is a shared ledger that is meant to record transactions and keep track of assets across a business network. However, in plain language, Blockchain is ultimately a software technology that is implemented to secure the payment process. Since Blockchain technology is one of the next-gen technologies that are going to dominate the future of the tech industry, it is vital that business giants should start leaning on blockchain app testing services to ensure a secure and bright future. Since the process involves extensive transactional verification, testing all the components of the payment gateway system along with other checks could help cut off any chances of loss, vulnerability, attacks, or system failure at any point in time. Let us quickly jump on understanding the key characteristics of testing Blockchain-based Applications while working on the testing aspects related to blockchain software testing practices, the tools, and most importantly, forming the right teams. When you start working on Blockchain testing, it needs you to understand that any transactions run through Blockchain change their current state. Thus, making any edits to the particulars requires the use of Miners that help to verify a particular transaction which could get extremely expensive.
