Testing

Website Foundation uses Vitest with Astro's getViteConfig() integration. Tests live in tests/unit/ and tests/integration/.

Running Tests

bun run test          # Run all tests once (42 tests, 7 files)
bun run test:watch    # Run in watch mode

Configuration

vitest.config.ts uses Astro's Vite config wrapper:

import { getViteConfig } from "astro/config";

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

Test Helpers

tests/setup.ts exports two helpers:

• createMockEnv() — Returns a mock Cloudflare runtime env with all bindings (AI, SEND_EMAIL, secrets)
• createMockContext(request, env?) — Returns a mock API context with locals.runtime.env and request

Key Patterns

Mock Cloudflare modules before importing

vi.mock("cloudflare:email", () => ({
  EmailMessage: vi.fn().mockImplementation((from, to, raw) => ({ from, to, raw })),
}));

Test API routes

const request = new Request("http://localhost/api/contact", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "Test", email: "test@test.com", message: "Hello" }),
});
const context = createMockContext(request);
const response = await POST(context as any);
expect(response.status).toBe(200);

Validate schemas without Astro runtime

const result = blogSchema.safeParse({ title: "Test", ... });
expect(result.success).toBe(true);

See Vitest patterns and mock helpers for detailed examples.
