How do you test new and emerging systems?

由人工智能和领英社区提供技术支持

Testing new and emerging systems is a crucial part of systems management, as it ensures that the systems are reliable, secure, and functional before they are deployed or integrated. However, testing new and emerging systems can also pose many challenges, such as dealing with complex and dynamic environments, unknown risks and dependencies, and evolving user expectations and requirements. In this article, we will discuss some of the best practices and strategies for testing new and emerging systems, and how to overcome some of the common pitfalls and problems.

1 Define the testing scope and objectives

The first step in testing new and emerging systems is to define the testing scope and objectives, which should be aligned with the system's purpose, goals, and expected outcomes. The testing scope and objectives should specify what aspects of the system need to be tested, how they will be tested, and what criteria will be used to evaluate the test results. The testing scope and objectives should also consider the system's context, such as its target users, stakeholders, regulations, and standards. Defining the testing scope and objectives will help to plan and prioritize the testing activities, and to communicate the testing expectations and requirements to the relevant parties.

Defining the testing scope for a new system involves specifying what will be tested and what won't. It includes objectives, system components, testing levels and types, environments, constraints, exclusions, acceptance criteria, test data, dependencies, risk assessment, schedule, reporting, and roles. This clarity ensures efficient and goal-aligned testing. These example best highlight the specific objectives and the elements included or excluded in the testing scope for different types of projects. Web Application Testing Scope: Objective: Ensure the functionality and usability of our e-commerce website. In Scope: Login, product search, checkout process. Out of Scope: Payment gateway (external service).

2 Choose the appropriate testing methods and tools

When testing new and emerging systems, it's important to select the right testing methods and tools that are suitable for the system's characteristics, complexity, and maturity. These methods and tools must be able to capture and measure the system's performance, functionality, usability, security, and quality, as well as identify and report any defects or issues. Furthermore, they should be flexible enough to adapt to changes or evolution during testing. Common testing methods and tools for new and emerging systems include simulation and emulation (creating virtual or artificial environments or scenarios), prototyping and experimentation (creating early versions of the system or components), user testing and feedback (involving real or potential users), and verification and validation (checking that the system meets requirements).

To choose the right testing methods and tools for a project, start by understanding project requirements and constraints. Identify the necessary testing types and research suitable tools with the required features and community support. Evaluate tools through trials, consider open source vs. commercial options, and involve your team. Plan for training and ongoing assessment while documenting your choices for future reference. Adapt your selections as needed to ensure effective testing aligned with project goals.

3 Apply the testing best practices and principles

The third step in testing new and emerging systems is to apply the testing best practices and principles, which should guide and improve the testing process and outcomes. It is important to test early and often, beginning as soon as possible and repeating frequently throughout the system's development and deployment lifecycle. Additionally, it is beneficial to test iteratively and incrementally, breaking down the system or its components into small chunks and building on the previous test results. Systematic and comprehensive testing is also critical, examining the system or its components from different perspectives such as functional, non-functional, structural, behavioral, and environmental. Lastly, testing realistically and critically ensures that the system is reliable and valid by testing it in realistic situations with relevant data.

One way I like to build my requirements and testing specification for novel products is to use existing state-of-the-art resources for related products. For example, if the product is a novel patient support with no IEC technical specification, I may use existing IEC standards for patient support beds and lifts as my basis, then modify their test protocols to work for the novel product. Often a substantial number of requirements are directly applicable to related products. Use your judgement though, and always consult your Notified Body or regulatory authority.

I believe the below would be apt testing practices and principles effectively: Understand project context, objectives, and constraints. Involve stakeholders for input and expectations. Define clear testing objectives and goals. Choose appropriate testing levels and types. Prioritize test cases based on criticality. Create comprehensive test plans. Design precise and traceable test cases. Consider test automation for efficiency. Start testing early in the development process. Use realistic and representative test data. Integrate testing into CI/CD pipelines. Promote collaboration and effective communication. Regularly review and update testing practices. Document and report results Implement risk-based testing for resources allocation

4 Manage the testing risks and challenges

The fourth step in testing new and emerging systems is to manage the testing risks and challenges, which should be anticipated and mitigated as much as possible. These risks and challenges may include uncertainty and ambiguity due to lack of knowledge or experience about the system or its environment, complexity and interdependency arising from the system's features, functions, components, or interactions, scalability and sustainability due to the system's ability to handle increasing demands or loads, or ethical and legal issues related to compliance with laws, regulations, or standards. Anticipating and mitigating these risks and challenges is essential for successful testing.

5 Document and report the testing results and outcomes

When testing new and emerging systems, the fifth step is to document and report the testing results and outcomes. This should be done clearly and effectively, including the scope and objectives of the testing, the methods and tools used, the best practices and principles applied, any risks and challenges encountered, and the findings and recommendations. The scope should summarize what was tested, how it was tested, and why it was tested; the methods should explain what was used to test the system or its components, and how they were used; best practices should guide and improve the testing process; risks should be identified and analyzed; findings should present and interpret the testing data; and recommendations should provide any suggestions or improvements for the system or its components.

6 Learn and improve from the testing experience

The sixth and final step in testing new and emerging systems is to learn and improve from the testing experience, which should be reflected upon and acted on. The testing experience should provide valuable insights and lessons for the system's development and deployment, as well as for the testing practice and profession. It should also foster a culture of continuous learning and improvement, prompting the testing team and the system team to review their process and outcomes. Celebrating achievements, sharing knowledge, updating methods, tools, techniques, and technologies, as well as planning for the next cycle or project are all important steps to take in order to recognize and reward the efforts of both teams. Setting goals and strategies for the future will ensure that the testing experience is a beneficial one.
