Import path: personaforge/test-utils · Public symbols: 15 · Guide: /guide/eval

What it is

personaforge/test-utils is a public entry point of personaforge. Import it directly; you only pull in this feature's code (subpath exports are tree-shakeable and optional native deps load lazily).

Install

npm i personaforge
# or: bun add personaforge · pnpm add personaforge · yarn add personaforge

Import

import { createMockLLM, createMockAgent, runScenario } from 'personaforge/test-utils';

Public API surface

• Factories / functions — createMockLLM, createMockAgent, runScenario
• Classes — MockLLMProvider
• Interfaces — AgentRunResult, MockableAgent, MockLLMCall, MockLLMOptions, MockLLMHandle, MockAgentRun, MockAgentOptions, MockAgentHandle, ScenarioStep, ScenarioStepResult, ScenarioResult

Minimal use

import { createMockLLM, createMockAgent, runScenario } from 'personaforge/test-utils';

// `createMockLLM` is the primary entry for this feature.
// See the type signature for full options.
const result = createMockLLM(/* opts */);

Verify it works

• Type-check: npx tsc --noEmit resolves personaforge/test-utils with no missing-module error.
• Runtime: node -e "import('personaforge/test-utils').then(m => console.log(Object.keys(m)))" lists the exports above.
• Behavior: follow the runnable example in /guide/eval.

Common failures

• Cannot find module 'personaforge/test-utils' — package not installed or stale build; run npm i personaforge and rebuild.
• Cannot find module '<peer>' at call time — this feature lazy-loads an optional native/SDK dep; install the one named in the error.
• Type errors after upgrade — check CHANGELOG.md for the symbol you import; names above are the current contract.

Rollback

• Remove the import and the feature is gone from your bundle (subpaths are isolated; nothing else depends on importing it).
• Pin a known-good version: npm i personaforge@<version>.
