Testing

kubb/kit/testing is a separate subpath for the Vitest-backed helpers used to test plugins, generators, and adapters. It stays separate from kubb/kit so importing the authoring toolkit never pulls Vitest into a plugin's runtime dependencies.

plugin.test.ts

import { , ,  } from 'kubb/kit/testing'

createMockedPlugin and createMockedAdapter build a minimal plugin or adapter for a test without wiring a full config. createMockedPluginDriver builds a driver around a set of plugins so a generator can run through its real lifecycle in isolation. renderGeneratorSchema, renderGeneratorOperation, and renderGeneratorOperations call a generator's schema(), operation(), or operations() method directly against a node fixture and return the resulting files. matchFiles asserts a set of generated FileNodes matches expected paths and contents, the assertion most generator tests end on.
