Bot, an artificial intelligence (AI) powered chat program, is changing the face of the technology-human interface. It is being declared as the new application of the future. Interestingly, non-profit organizations with substantial resources and technological support are trying to explore ways to use chatbot technology for the larger good. Can Agile test strategy with effective implementation of Service Virtualization (SV) bring relevance and add value for such path-breaking projects?
In an ideal scenario, software testing and operations teams are expected to work in tandem and deliver quality with speed, cost effectively. In real development environments, things change, as applications get complex with numerous interdependent factors that pose challenges in the production phase.
Service Virtualization emulates the performance of services in a virtual set-up to help address the challenges of Service-oriented Architecture (SOA) testing strategy. At the same time, if implemented effectively, SV can speed up the testing and development process.
With Service Virtualization, DevOps teams can leverage virtual services instead of pooling in resources from production. This can boost recurring and thorough testing even if any key components are not present within your system architecture. It helps emulate the behavior of essential elements that would eventually be present in the final production set-up.
Today, applications are multifaceted and need to be robustness in order to manage any real-time defects. Using Service Virtualization with your Agile Testing strategy can help establish a comprehensive development and testing mechanism. Additionally, it enables Integration Testing for complex applications way ahead in the development process by eliminating bottlenecks that could compromise time-to-market and delay the production for an Application under Test (AUT).
Service Virtualization is exceptionally relevant while developing complex Cloud-based, API-based, and SOA-based systems. It is critically important in a situation where the required hardware and software components are not easily available for testing.
Enterprises and development teams are increasingly implementing Service Virtualization with an Agile approach to enhance productivity, cut down testing costs, and deploy quality software within a shorter time span. It can further support parallel development practices, accelerate time-to-market, enhance quality, and encourage collaborative efforts between testing and development teams.
Service Virtualization has been enabling organizations to gain a competitive advantage over other organizations that are still going by the linear development strategy. It helps eliminate roadblocks that disrupt Agile and parallel development.
Key Benefits Service Virtualization Brings to Agile Testing Strategy
- Promptly creates patterns/situations that emulate the expected actions
- Swiftly upgrade the asset when requirements change
- Provide shared access to evolving assets
- Testing on the go
Agile development/testing takes a ‘Sprint’ approach, where various teams are working simultaneously to pursue shorter goals. So, there are numerous instances where hiccups are felt while working on interconnected components within a system. These deadlocks are experienced when teams are waiting to access dependent functionalities.
Service Virtualization helps minimize such deadlocks by virtually providing resources and assets. For instance, by using a graphical interface you can quickly create a virtual asset that presents the required behavior for development and testing tasks.
In a development scenario, and specifically in an Agile set-up, requirements constantly evolve. So, the virtual assets should be flexible and easy to alter in such situations. Service Virtualization helps do that easily and quickly. This is one of the key requirements in an Agile Testing approach.
In an Agile approach, diverse teams work on diverse systems where resources are required for testing and development. Various team members are in need of the virtual assets, for instance, developers, testers, business analysts, or any team member who could be located anywhere globally.
Service Virtualization facilitates a scenario where the assets are available for all at any given point of time, on-demand!
With the conventional and traditional approach, testing and development teams have to wait for the completed applications to deploy and check for proper functional, integration, and performance testing. Service Virtualization helps build a robust application by generating virtual assets that can be leveraged for testing the application’s performance and any other functionality almost in a near-LIVE scenario.
All-in-all, Service Virtualization helps to gauge the holistic performance/behavior of an application in a scenario that could be relevant once the application goes LIVE. It is useful for test-driven development (TDD) teams to speed up the production schedule by focusing on identifying the bug at the API layer.
Leveraging SV services is recommended to save costs in the development and testing cycle. The software development team can save costs and time when the development cycle requires repeated testing against dependent third-party components.
What to Expect From Service Virtualization in the Future
Saving time and money have been the key reasons for considering Service Virtualization, as popular SV software applications can run on commonly available and affordable hardware. Also, virtually available resources can be easily modified and recycled to fit the requirements.
Nevertheless, the decision to set up an SV solution totally depends on the organization’s cost-benefit analysis. With the changing dynamics and growing importance of testing/quality assurance, SV is a needed option and a feasible one. For instance, experts say that virtualizing the API itself is a highly cost-effective decision.
Today, performance and functionality of the application is a top priority. It is a business-critical decision and interface for determining viability and commercial success. Agile testing and workflow methodologies are becoming common, so implementing a resourceful Service Virtualization tool for parallel development tasks becomes essential.
The idea is to make assets available anytime anywhere!
Enterprises are becoming more inclined to use business-oriented architectures like Service Oriented Architecture (SOA) and Service Virtualization with the sheer objective to build robust applications and reach the market faster. An Agile approach further brings flexibility and collaboration to teams in order to deliver innovative enterprise level applications/critical technology experiments.
