Part Factory Test Data

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
Build test data with @kensio/part-factory, keeping in the factory everything a test does not care about, passing dependencies at call time so factories stay independent, and choosing between StaticFactory, DynamicFactory, VariantFactory, MappedFactory and AsyncMappedFactory. Use when writing test fixtures or builders, when a test file is full of object literals, when a shared event, message or payload shape is being hand-written, when a required field is about to be made optional to ease test setup, and when tempted to wrap a factory in a helper function that applies overrides.

From the source SKILL.md

[Part Factory](https://partfactory.dev/) (@kensio/part-factory) builds typed objects for tests. A factory holds the defaults, and make(overrides) returns an object with the overrides applied down through the nested structure.

What this skill does

Part Factory Test Data is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/part-factory-test-data/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when writing test fixtures or builders, when a test file is full of object literals, when a shared event, message or payload shape is being hand-written, when a required field is about to be made optional to ease test setup, and when tempted to wrap a factory in a helper function that applies overrides.
