Example showing how to mock $env in Playwright tests for SvelteKit.

The following is needed to mock the $env module.

1. Add the following to tsconfig.json

    // Everything below is required for Playwright tests to access path aliases
    "baseUrl": ".",
    "paths": {
      "$lib": ["src/lib"],
      "$lib/*": ["src/lib/*"],
      "$env/*": ["tests/e2e/mocks/env/*"]
    }
   

2. Set testDir in playwright.config.ts to 'tests/e2e'.

3. Mock $env/dynamic/private by adding the file tests/e2e/mocks/env/dynamic/private.ts and export a env const. E.g.

export const env = process.env
