The validation of both functional and non-functional requirements should be done for blockchains like in any other application. Functional testing should focus on unit, integration and system testing, while non-functional testing should be focused on security and performance testing. The continuous integration and continuous delivery approach should be adopted where testing is done several times in a day, and a version control system should be used to keep tabs on updates. Service virtualization should be used to access virtual forms of the required testing stages.

Though organizations have started adopting agile, DevOps, and automation in their test approaches, effective implementation of these processes and insights about the level of risks associated with the application are always a challenge...
