Scenario
A scenario is a concrete description of a situation or conditions, often including actions and expected or possible outcomes, for analysis or evaluation.
BDD in Action, Second Edition
A scenario is a concrete description of system behavior under specified conditions, typically expressing an example that can be evaluated or automated.
- How it is used
- Uses concrete feature examples to align stakeholders, define acceptance criteria, and verify delivered behavior.
- How deep it goes
- Develops scenario syntax, refinement, organization, and writing practices; keeps low-level interaction details outside business-focused scenarios.
- Examples
- Uses frequent-flyer points, train departures, bank transfers, and hotel searches to expose rules and ambiguities.
- What you can do after
- Practice/perform writing focused, independent scenarios that stakeholders can discuss and BDD tools can execute.
The Art of Unit Testing 3e
A test scenario is a defined situation, set of inputs, or conditions under which software behavior is tested.
- How it is used
- Names the conditions under which a unit or feature is checked, guiding readable tests and test-recipe planning.
- How deep it goes
- Defines scenarios through test names and planning rules, then relates their placement to testing levels without detailing framework internals.
- Examples
- Uses password verification with a failing rule, and names null values, successful login, providers, and unsuccessful login results as scenarios.
- What you can do after
- Apply it by naming conditions clearly and distributing planned scenarios across test levels for confidence with fast feedback.
Architecture Modernization: Socio-technical alignment of software, strategy, and structure
A scenario is a concrete situation describing what can happen when a particular action is performed under specified conditions.
- How it is used
- Uses concrete situations to challenge designs, uncover coupling, and refine domain or architectural models.
- How deep it goes
- Develops scenarios through repeated walkthroughs, edge-case discovery, and optional code spikes rather than stopping at abstract models.
- Examples
- Uses order cancellation, warehouse status, refund requests, green scenario stickies, and resulting domain events.
- What you can do after
- Apply via EventStorming or Example Mapping to expose edge cases, clarify business rules, and guide model refinement.
