How do you apply business logic to test solution designs?

1 Identify the business logic sources

The first step in the solution design process is to identify the sources of business logic that are relevant to the solution. These sources can include business requirements documents, rules, models, policies, and stakeholders. To do this, you can employ various techniques such as interviews, workshops, surveys, observation, prototyping, and modeling. This will help you to better understand the functional and non-functional requirements, constraints, conditions, actions, structure, relationships, flows of business entities and activities, principles, guidelines and standards that shape the business decisions and actions, and the vision and expectations of stakeholders.

2 Define the test scenarios and cases

The second step is to define the test scenarios and cases that will verify and validate the solution design against the business logic. A test scenario is a high-level description of a situation or event that involves the solution and its users, while a test case is a detailed specification of the inputs, outputs, steps, and expected results for a test scenario. To ensure these scenarios and cases are effective, they should meet certain criteria such as coverage, completeness, consistency, clarity, and traceability. These criteria should be aligned with the business logic sources and avoid any contradictions or conflicts. Additionally, it is important that the scenarios and cases are clear and understandable to the testers and stakeholders. To document and manage them, you can use various tools such as spreadsheets, databases, diagrams, or software applications.
