Using Agile and DevOps testing in Blockchain Apps

Keeping under consideration the challenges that testers face while testing blockchain apps along with quicker deployment and integrations in the actual environment, it is important for the QA team to understand the ways to evaluate and debug the blockchain app. The software testing companies conduct a few “specialized testing” methods like:

1. NODE OR PEER TESTING

A node is a device on the blockchain network that has the capacity to perform various tasks like a store, create, receive, and transfer data along dispersed network routes. When several nodes interact with each other, it is called peers. Nodes communicate with a network and achieve more details regarding the network via their peer. The main purpose of this type of testing is to secure the integrity of shared ledgers and networks.

2. SMART CONTRACT TESTING

Smart contracts must not be mixed with the legal contract of the law or court. It is a computer-generated program that surely executes transactions when some pre-coded and pre-defined circumstances and business rules and logic are satisfied. This code or computer program functions on top of a blockchain containing pre-defined rules established by the parties of this contract.

BLOCKCHAIN APP TESTING: DEVOPS AND AGILE TESTING TIPS

Agile is a method of project management used for software development. In this, solutions and requirements grow through a partnership between self-organizing cross-functional teams. This is considered an iterative procedure for software delivery. This helps to create software incrementally from the start of the project and the capacity to acclimatize to the changes as quick or quicker than changes can occur. Other similarities comprise Agile functions by cutting down projects into smaller portions of user-functionalities, also called user stories. It is then prioritized and continuously performed in short cycles known as repetitions. You can also correlate this with the blocks being produced and assessed in the blockchain. In fact, the agile manifesto can be associated with a blockchain working in terms of a decentralized, transparent protected, and efficient system, and smart contracts. The 4 elements of the agile manifesto incorporate:

• Individuals and interactions over methods and tools
• Working software over complete documentation
• Responding to change over following a plan
• Customer collaboration over agreement negotiation

On the contrary, the main purpose of DevOps is to promote the continuous deployment and constant delivery procedure by restructuring the connection between app development and testing and deployment team. This is something related to a node that performs various tasks along with dispersed network routes. Another important component is DevOps in continuous testing.  It is a method for executing automated tests as an essential part of the software delivery pipeline to achieve immediate feedback associated with business risks. These risks are often connected with a software release candidate. On similar lines, blockchain needs a real-time authentication because all members in the chain can see the associated details of a block directly.

Best practices from DevOps incorporate continuous integration testing. Whereas, best methods from Agile include testing and repetitions. This can have an important impact on the techniques via which blockchain apps are examined and deployed. One of the most popular strategies is the “Shift Left Testing” approach. Through this approach, you can change testing to the left of the lifecycle. As a consequence, earlier tests can be performed with the option of non-stop reuse. This entire technique helps to expose defects in the early stages of the lifecycle and avoid production surprises.
