Some Common Types of Testing

Blockchain applications are gaining popularity, especially by some prominent industries due to the fact that they are decentralized and follow a secure structure. 

Various types of testing are performed to ensure complete test coverage and achieve excellence for blockchain apps.

• Functional testing is one type of testing that evaluates several functional parts of the Blockchain, such as smart contracts. 
• Application Programming Interface testing is also a part of Blockchain testing as it addresses the interaction between apps and ensures that API requests and replies are formatted and managed accurately. 
• To ensure smooth cooperation, node testing is also crucial. In this type of testing, all heterogeneous nodes on the Blockchain network must be validated and tested independently. 
• Performance testing and load testing are also crucial in order to check how Blockchain application performs in production and under specific workloads and network conditions and suggests the methods of fine-tuning the system.

Popular Tools for Testing Blockchain Apps 

Now let’s talk about some of the popular tools for testing Blockchain applications.

Truffle Suite

This framework is known to offer good testing features such as automated testing, especially for Ethereum developers, and extends its functionalities beyond testing as well. By utilizing this framework, developers can write simple and manageable tests in two different ways, including javascript and Solidity.

Ethereum Tester

Ethereum Tester is a tool suite for testing applications based on Ethereum. We can also say that it is an open-source testing library that is available as a Github repo. Moreover, this tester provides a strong guarantee that backends can be swapped out without affecting the data formats of both the input arguments and return values. 

Moreover, it is easy to set up with manageable API support for various Testing requirements with this tool.

 Embark

Embark is another tool for testing smart contracts, and its framework allows you to develop and deploy decentralized applications easily and quickly. This tool enables you to perform test-driven development with contracts, keep track of deployed contracts, manage different chains, manage complicated systems of interdependent contracts, and other crucial tasks.

Challenges in Blockchain Testing

Now, as we have learned about a few common types of Blockchain testing and looked at popular tools, let’s explore what the major challenges are.

Understanding Technology– The major challenge is that Blockchain is comparatively a new technology, and very few have in-depth knowledge related to this futuristic technology. In order to test an application, its domain knowledge is very important. 

Selecting the right tool: There are not many tools for testing Blockchain-based applications, and therefore, choosing the right tool is often difficult.

Defining Test Strategy– Defining a strategy for testing a Blockchain application is crucial, and it requires a thorough understanding of the technology.

Block Size and Chain Size– As a part of testing, testing for block size and chain size is also essential. This is important because apps may fail without proper validation of block and chain size.

Integration Testing– As the name suggests, integration testing is all about integrating all components involved in the Blockchain app and then testing in order to ensure that each component is integrated correctly to avoid any failures.

Securing Data– Another most important challenge associated with the testing phase is that of security. Securing the data is crucial as malicious attacks can impact the Blockchain apps.
