---

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

   # Ensure MSW is installed correctly
   npm install -D msw@latest
   

2. Update Test Setup Files for MSW v2

   // 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

   // 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

   // __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

   # 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

   // 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

   // 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

   // __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

   # 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.
