In the codebase at /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api, I need to understand how queryClientV5 is set up and whether it gets added to global.testQueryClients (which is used in afterEach to cancel queries).

Please look at: 1. packages/shared_context/src/react-query/queryClientV5.ts (or similar path - find the file that exports queryClientV5) 2. How __testQueryClients__ is populated - search for "testQueryClients" in the codebase 3. packages/@doctolib/dmp/src/hooks/tests/DmpSharingService.test.ts - look at the top of the file (first 100 lines) to see how queryClientV5 is imported and used in the test

Report the exact file paths and relevant code snippets.

Perfect! Now I have all the information needed. Let me create a comprehensive report with the exact file paths and code snippets:

Summary

I've found exactly how queryClientV5 is set up and how it gets added to __testQueryClients__. Here's the complete picture:

1. QueryClientV5 Setup

File: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/shared_context/src/react-query/queryClientV5.ts

import type { Query, QueryClientConfig } from '@tanstack/react-query-v5'
import { MutationCache, QueryCache, QueryClient } from '@tanstack/react-query-v5'
import { captureException } from '@doctolib/error_helpers/public'
// ... other imports ...

export const queryCacheOptionsV5 = {
  onError: (error: unknown, query: Query<unknown, unknown, unknown>) => {
    // Error handling logic...
  },
}

export const mutationCacheOptionsV5: typeof MutationCache.prototype.config = {
  onError: (error, _variables, _context, mutation) => {
    // Mutation error handling logic...
  },
}

const queryClientOptions: QueryClientConfig = {
  defaultOptions: queryClientDefaultOptions,
  queryCache: new QueryCache(queryCacheOptionsV5),
  mutationCache: new MutationCache(mutationCacheOptionsV5),
}

export const queryClientV5 = new QueryClient(queryClientOptions)

2. How __testQueryClients__ is Populated

File: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/app/assets/javascripts/packages/test-helpers/ReactQueryContext.tsx

export const getDefaultTestQueryClientV5 = () => {
  const client = new QueryClientV5({
    defaultOptions: queryClientDefaultOptions,
    queryCache: new QueryCacheV5(queryCacheOptionsV5),
    mutationCache: new MutationCacheV5(mutationCacheOptionsV5),
  })
  window.__testQueryClients__?.push(client)  // <-- ADDED TO GLOBAL ARRAY
  return client
}

3. Window Type Definition

File: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/app/assets/javascripts/types/commons/window.ts

declare global {
  interface Window {
    // ↓↓↓↓ ONLY FOR TEST PURPOSES ↓↓↓↓
    __testQueryClients__?: { cancelQueries: () => Promise<void>; clear: () => void }[]
    // ↑↑↑↑ ONLY FOR TEST PURPOSES ↑↑↑↑
  }
}

4. Test Setup & Cleanup (AfterEach)

File: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/jestUtils/testingLibraryConfig.js

global.beforeEach(() => {
  setupDayjs('en')
  if (!global.Date.isFake) mockToday()
  setupConsoleErrorSpy()
  global.__testQueryClients__ = []  // <-- INITIALIZED EMPTY
})

global.afterEach(async () => {
  // Cancel in-flight React Query requests to prevent HappyDOM teardown errors
  const clients = global.__testQueryClients__ || []
  await Promise.all(clients.map((client) => client.cancelQueries()))  // <-- CANCELS QUERIES
  clients.forEach((client) => client.clear())  // <-- CLEARS CACHE
  global.__testQueryClients__ = []  // <-- RESETS
  expectNoConsoleError()
})

5. How DmpSharingService.test.ts Uses It

File: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/dmp/src/hooks/tests/DmpSharingService.test.ts (first 100 lines)

import { queryClientV5 } from '@doctolib/shared_context'

describe('DmpSharingService class', () => {
  afterEach(() => {
    queryClientV5.clear()  // <-- MANUAL CLEANUP (in addition to global afterEach)
  })
  // ... rest of tests ...
})

Key Findings

1. queryClientV5 is exported from @doctolib/shared_context and is a singleton instance
2. When used in tests, the test helper getDefaultTestQueryClientV5() creates a new instance per test and automatically pushes it to window.__testQueryClients__
3. The global afterEach (in jestUtils/testingLibraryConfig.js) automatically: - Calls cancelQueries() on all clients in the array - Calls clear() on all clients to clear the cache - Resets the array to empty
4. The DmpSharingService.test.ts imports the singleton directly and calls queryClientV5.clear() in its afterEach hook as an additional safety measure
