Scenariosfrom

Scenariosfrom is a generic term used in software development and related fields to describe a utility or pattern that generates a set of scenarios from a given source. The concept is language- and framework-agnostic, and its exact implementation varies by project. At a high level, scenariosfrom refers to creating concrete scenario objects by applying templates, seeds, or transformations to an input collection.

Typical purpose and usage

The primary goal of scenariosfrom is to automate scenario generation for testing, simulations, or narrative design. It commonly accepts inputs such as scenario templates, seed data, or a source dataset, and may apply optional filters or transformation functions. The output is typically a list or iterable of scenario objects, each containing fields like id, title, description, preconditions, steps, expected outcomes, and metadata. Scenariosfrom enables parameterization, combinatorial expansion, and data-driven generation, reducing manual authoring while increasing coverage and consistency.

Common patterns

In many languages, the function or method is named in a way that emphasizes construction from a source. Examples in pseudocode include: JavaScript: const scenarios = scenariosFrom(scenarioTemplates, seedData); Python: scenarios = scenarios_from(templates, data, transformer). Implementations may vary between returning immutable collections, streaming generators, or in-place materialization, depending on performance and memory considerations.

Relation to related concepts

Scenariosfrom overlaps with data-driven testing, parameterized testing, scenario templates, and scenario generators. It is often used in conjunction with validation, reporting, and analytics to trace how generated scenarios map to requirements or user stories.
