Why Blockchain Testing Is Important?

Unlike most data structures, once a smart contract is deployed to the blockchain, changes can not be made, so ensuring the efficacy of a contract is very important. It’s up to QA engineers to perform comprehensive and custom sets of tests to make sure that mistakes, which cannot be fixed, are identified and mitigated.

When a defect is discovered in production the smart contract can’t be updated or rolled back, and a new version of the smart contract must be created and deployed. These new versions have to be manually created by applying the previous data into the new contract - an endeavor costly in time and resources for business leaders.

Blockchain Testing Challenges

QA engineers face a unique set of challenges when testing blockchain applications and smart contacts due to them being relatively new and evolving at a rapid pace. A few of the most common challenges that teams encounter are:

  • Blockchain transactions are Irreversible: Implementing blockchain without the utmost care is risky to organizations and their users because of the transactions being irreversible. Not having controls in place to avoid redundancy and provide additional safety measures is one of the most common challenges teams encounter.
  • In-depth knowledge of technology: Blockchain is a new technology and needs to be tested by well-trained experts with domain knowledge.
  • Continuous Addition of Blocks: Blockchain technology is meant to be used to store and process large amounts of data, but in order to accomplish this, new blocks are added at a quick and consistent pace. These continuous additions can create a strain on QA engineers and can easily become a QA testing bottleneck.
  • Integration Testing: Integration testing must be carried out frequently to avoid any failures, since there are multiple components involved in designing a Blockchain application.
  • Handling crypto-graphical data: The primary goal of blockchain is the transmission of encrypted data. There is a high risk of failure if the transmission of the data is not tested properly during the development and QA processes.

Blockchain Software Testing Methodology

Our team ensures that each of our clients' blockchain applications receive the custom and comprehensive attention they deserve. Below are a few of the most common tests completed when working with blockchain applications.

Blockchain Software Testing Methodology

End-to-End Testing

This is done to reduce recurring errors, which reduces the overall amount of testing that needs to be done on the application.

User Interface Testing

UI testing includes functional testing the user interface controls to verify that the application is functioning correctly for the end users.

Unit Testing

This is done to isolate each part of the program and validate that individual parts of the system are working correctly.

API Testing

This ensures consistency when testing a blockchain application and enables the product to have continuous improvements.

Performance Testing

This test validates the performance of an application when inputting large data sets, or several contracts, that are meant to be executed simultaneously.

Cross Browser & Cross Device testing

Dapps (Decentralized applications) have a number of users running on a local Ethereum node, which makes them accessible over web browsers and mobile devices. This makes cross-browser/cross-device testing for Dapps crucial to ensure that users on all platforms and devices have a seamless experience.

Our Blockchain Testing Tools Include

Ethereum Tester
This platform is designed to test web3 integrations, smart contracts, APIs, and other blockchain technologies.

Populus
This is a framework known for its relatively easy integration due to it being developed around the py.test framework.

Truffle
Truffle is a combination of a development environment, testing frameworks, and asset pipelines. It leverages ethereum logic and is helpful when teams are releasing distributed applications.

Embark
The goal of Embark is to make testing smart contacts as easy as possible. This is done by allowing developers or testers to choose what features make most sense to you when building or testing decentralized apps.

Exonum Testkit
This tool allows testers to test transactions executed and APIs in the coincident environment.
