#Testing

Addfox has built-in support for Rstest and recommends running tests through addfox test.

#Check dependencies first

Before running tests, make sure required dependencies are installed:

pnpm add -D @rstest/core

For browser E2E tests, also install:

pnpm add -D @rstest/browser playwright

#Unified command

Use:

addfox test

This runs tests through the Addfox test workflow instead of manually wiring low-level commands.

#Unit Tests

Best for:

• utility functions
• message handlers
• storage/state logic

Common file naming:

• *.test.ts
• *.spec.ts

#E2E Tests

Best for:

• extension loading checks
• popup/content/background integration flows
• user-facing regression paths

Run E2E as part of CI or release validation.

#Minimal config example

// rstest.config.ts
import { defineConfig } from "@rstest/core";

export default defineConfig({
  test: {
    include: ["**/*.test.ts", "**/*.spec.ts"],
  },
});

#Suggested script

{
  "scripts": {
    "test": "addfox test"
  }
}
