@lpsmods/minecraft-server-ui-mock

Emulates the @minecraft/server-ui package for testing.

What is this?

This package provides a mocked version of @minecraft/server-ui for testing. It helps you run unit tests without needing the real Minecraft Bedrock scripting environment.

Using with Vitest

Install the mock package as a dev dependency:

npm install -D @lpsmods/minecraft-server-mock @lpsmods/minecraft-server-ui-mock

Then alias @minecraft/server-ui in your vitest.config.ts:

import { defineConfig } from "vitest/config";

export default defineConfig({
  test: {
    globals: true,
    server: {
      deps: {
        inline: ["@minecraft/math"],
      },
    },
  },
  resolve: {
    alias: {
      "@minecraft/server": "@lpsmods/minecraft-server-mock",
      "@minecraft/server-ui": "@lpsmods/minecraft-server-ui-mock",
    },
  },
});

Now your source code can keep importing from @minecraft/server-ui, and when running tests, Vitest will automatically redirect those imports to this mock package.
