@modular-react/testing

Router-agnostic testing utilities for modular-react modules. Resolve module contributions (slots, lifecycle) without rendering.

Installation

npm install -D @modular-react/testing

What's included

• resolveModule: resolves module contributions (slots, lifecycle) without rendering
• createMockStore: creates a store pre-populated with test state (uses @modular-react/core's built-in store)
• Types: ResolveModuleOptions, ResolveModuleResult

Usage

import { resolveModule, createMockStore } from "@modular-react/testing";

const { slots, entry, onRegisterCalled } = resolveModule(myModule, {
  defaults: { commands: [], badges: [] },
  deps: { auth: { user: { isAdmin: true } } },
});

expect(slots.commands).toHaveLength(2);
expect(entry.id).toBe("my-module");

For rendering modules with a router, use the router-specific testing packages (@react-router-modules/testing or @tanstack-react-modules/testing).
