### **Phase 1: Stabilize Testing Infrastructure**

#### **Step 1.1: Debug Test Execution Issues**

**Objective:** Resolve issues preventing tests from executing successfully.

**Actions:**

1. **Check MSW Installation and Import Paths**
    ```bash
    # Ensure MSW is installed correctly
    npm install -D msw@latest
    ```

2. **Update Test Setup Files for MSW v2**
    ```typescript
    // vitest.setup.ts
    import { beforeAll, afterEach, afterAll } from 'vitest'
    import { server } from './tests/mocks/server'

    // Establish API mocking before all tests.
    beforeAll(() => server.listen())

    // Reset any request handlers that are declared as a part of our tests
    // (i.e. for testing one-time error scenarios)
    afterEach(() => server.resetHandlers())

    // Clean up after the tests are finished.
    afterAll(() => server.close())
    ```

3. **Create Mock Server for Vitest**
    ```typescript
    // tests/mocks/server.ts
    import { setupServer } from 'msw/node'
    import { handlers } from './handlers'

    // Setup requests interception using the given handlers.
    export const server = setupServer(...handlers)
    ```

4. **Verify Import in Test Files**
    ```typescript
    // __tests__/example.test.tsx
    import { render, screen, fireEvent } from '@testing-library/react'
    import AdvancedChatWindow from '@/components/chat/AdvancedChatWindow'
    import { server } from '../mocks/server'
    import { rest } from 'msw'

    // Establish API mocking before all tests.
    beforeAll(() => server.listen())

    // Reset any request handlers that are declared as a part of our tests
    afterEach(() => server.resetHandlers())

    // Clean up after the tests are finished.
    afterAll(() => server.close())

    test('renders AdvancedChatWindow and sends a message', async () => {
      const mockSendMessage = jest.fn().mockResolvedValue('AI response')
      render(<AdvancedChatWindow onSendMessage={mockSendMessage} />)

      const input = screen.getByPlaceholderText('Type your message...')
      fireEvent.change(input, { target: { value: 'Hello AI!' } })

      const sendButton = screen.getByRole('button', { name: /send/i })
      fireEvent.click(sendButton)

      expect(mockSendMessage).toHaveBeenCalledWith('Hello AI!', undefined)
    })
    ```

5. **Run Tests to Verify Fixes**
    ```bash
    # Run all tests
    npm run test

    # Run tests in watch mode
    npm run test:watch
    ```

**Outcome:** Successfully execute all tests without interruptions, ensuring MSW is correctly integrated with Vitest.

#### **Step 1.2: Finalize API Mocking Integration**

**Objective:** Ensure all API mocks are correctly set up for comprehensive testing.

**Actions:**

1. **Add Provider-Specific Handlers**
    ```typescript
    // tests/mocks/handlers.ts
    import { rest } from 'msw'

    export const handlers = [
      rest.post('/api/chat', async (req, res, ctx) => {
        const { message, config } = await req.json()

        if (config.provider === 'openai') {
          return res(
            ctx.status(200),
            ctx.json({
              response: `OpenAI response to: ${message}`,
              provider: 'openai'
            })
          )
        }

        if (config.provider === 'anthropic') {
          return res(
            ctx.status(200),
            ctx.json({
              response: `Anthropic response to: ${message}`,
              provider: 'anthropic'
            })
          )
        }

        if (config.provider === 'google') {
          return res(
            ctx.status(200),
            ctx.json({
              response: `Google AI response to: ${message}`,
              provider: 'google'
            })
          )
        }

        return res(
          ctx.status(400),
          ctx.json({
            error: 'Invalid AI provider specified'
          })
        )
      })
    ]
    ```

2. **Implement Streaming Response Mocks**
    ```typescript
    // tests/mocks/handlers.ts
    import { rest } from 'msw'

    export const handlers = [
      rest.post('/api/chat', async (req, res, ctx) => {
        const { message, config } = await req.json()

        // Simulate streaming with delay
        return res(
          ctx.status(200),
          ctx.body(
            JSON.stringify({
              response: `Streamed response to: ${message}`,
              provider: config.provider
            })
          ),
          ctx.delay(500)
        )
      })
    ]
    ```

3. **Add Test Cases for Provider-Specific Responses**
    ```typescript
    // __tests__/chat.test.tsx
    import { render, screen, fireEvent } from '@testing-library/react'
    import AdvancedChatWindow from '@/components/chat/AdvancedChatWindow'
    import { server } from '../mocks/server'
    import { rest } from 'msw'

    beforeAll(() => server.listen())
    afterEach(() => server.resetHandlers())
    afterAll(() => server.close())

    test('handles OpenAI provider response', async () => {
      render(<AdvancedChatWindow onSendMessage={jest.fn().mockResolvedValue('AI response')} />)

      const input = screen.getByPlaceholderText('Type your message...')
      fireEvent.change(input, { target: { value: 'Hello OpenAI!' } })

      const sendButton = screen.getByRole('button', { name: /send/i })
      fireEvent.click(sendButton)

      const response = await screen.findByText(/OpenAI response to: Hello OpenAI!/i)
      expect(response).toBeInTheDocument()
    })

    test('handles Anthropic provider response', async () => {
      render(<AdvancedChatWindow onSendMessage={jest.fn().mockResolvedValue('AI response')} />)

      const input = screen.getByPlaceholderText('Type your message...')
      fireEvent.change(input, { target: { value: 'Hello Anthropic!' } })

      const sendButton = screen.getByRole('button', { name: /send/i })
      fireEvent.click(sendButton)

      const response = await screen.findByText(/Anthropic response to: Hello Anthropic!/i)
      expect(response).toBeInTheDocument()
    })

    test('handles Google AI provider response', async () => {
      render(<AdvancedChatWindow onSendMessage={jest.fn().mockResolvedValue('AI response')} />)

      const input = screen.getByPlaceholderText('Type your message...')
      fireEvent.change(input, { target: { value: 'Hello Google AI!' } })

      const sendButton = screen.getByRole('button', { name: /send/i })
      fireEvent.click(sendButton)

      const response = await screen.findByText(/Google AI response to: Hello Google AI!/i)
      expect(response).toBeInTheDocument()
    })
    ```

4. **Run Tests to Verify API Mocks**
    ```bash
    # Run all tests to ensure provider-specific responses are handled
    npm run test
    ```

**Outcome:** All API mocks are correctly integrated, allowing thorough testing of multi-provider responses without relying on actual API calls.
