User description

Description

This Pull Request introduces a comprehensive End-to-End (E2E) testing pipeline using Cypress to validate the application's primary resume enhancement user journey. Since the application handles critical user paths like Firebase authentication and automated document enhancements, this test suite ensures that regressions are caught early without executing real, metered API credits.

Key implementations:

  • Cypress Suite Architecture: Created a foundational structure including cypress.config.js and support files configured to process local configurations seamlessly.
  • Firebase Session Mocking: Configured a custom cy.mockFirebaseAuth() support token command utility to cleanly establish dummy local storage sessions, bypassing manual sign-in forms deterministically.
  • Deterministic Pipeline Interception: Utilized cy.intercept() to step-stub network requests directed to /api/upload (multipart parser response handling) and /api/enhance/:id engines. This asserts that frontend score tracking elements (like the progress/score rings) and dynamic text blocks render correctly upon asynchronous route resolution.

CodeAnt-AI Description

Add Cypress end-to-end coverage for the resume enhancement flow

What Changed

  • Added a Cypress test that signs in with a mocked Firebase session, uploads a resume, and checks the enhancement page
  • The test now waits for the upload and enhancement responses, then verifies the score ring and enhanced resume text are shown
  • Added Cypress support files and config so the test suite can run against the local app consistently

Impact

✅ Fewer breakages in the resume upload flow
✅ Catch login and enhancement regressions before release
✅ Faster checks for the main resume review journey

📝 Walkthrough

Walkthrough

Adds a complete Cypress E2E test infrastructure for the frontend: a cypress.config.js with base URL and viewport settings, a mockFirebaseAuth custom command that seeds localStorage with a mock Firebase user, a support entry file wiring commands, and a resume-flow.cy.js spec that stubs auth and backend API calls to test the full resume upload and enhancement user journey.

Changes

Cypress E2E Infrastructure and Resume Flow Test

Layer / File(s) Summary
Cypress config and support setup
frontend/cypress.config.js, frontend/cypress/support/e2e.js, frontend/cypress/support/commands.js
Defines Cypress E2E config (baseUrl http://localhost:5173, 1280×720 viewport, supportFile path), imports the commands module in the support entry point, and registers a mockFirebaseAuth command that writes a deterministic Firebase user object to window.localStorage.
Resume enhancement E2E spec
frontend/cypress/e2e/resume-flow.cy.js
Adds a beforeEach block intercepting Identity Toolkit auth, /api/upload, and /api/enhance/:id with stubbed responses and aliases; the test drives dashboard navigation, PDF dropzone interaction, aliased request waits, route assertion, and UI assertions for score-ring, confidence-meter, and enhanced summary text.

Multi-selector may produce ambiguous results.

The selector .confidence-meter, .score-ring, [data-testid="score-ring"] uses comma-separated selectors, which matches if ANY of these elements exist. This may not accurately test the intended UI components. Consider using a more specific selector or verifying each element individually.

Inline comments:
In `@frontend/cypress/e2e/resume-flow.cy.js`:
- Line 39: The selectFile method call in the resume-flow.cy.js test references a
fixture file at cypress/fixtures/test-resume.pdf that does not exist. Create the
missing cypress/fixtures/ directory structure under the frontend directory and
add a valid test-resume.pdf file to this directory. This file will be used by
the selectFile method with the drag-drop action when the test executes.
- Around line 14-24: The cy.intercept() call in the resume-flow.cy.js test is
intercepting an incorrect API route. The actual frontend API call uses POST
/api/enhance without any resume ID in the URL path, but the intercept is
configured to match POST /api/enhance/mock-resume-uuid-456. Update the
cy.intercept() call to change the intercepted endpoint from POST
/api/enhance/mock-resume-uuid-456 to POST /api/enhance so it correctly matches
the actual API route being called by the frontend with resumeText and
preferences in the request body.

In `@frontend/cypress/support/commands.js`:
- Around line 3-11: Update the localStorage key in the command to match
Firebase's documented format by including the API key and [DEFAULT] suffix.
Replace the static key 'firebase:authUser:' with a dynamic key that uses the
format 'firebase:authUser:{apiKey}:[DEFAULT]' where the apiKey is retrieved from
Cypress.env('VITE_FIREBASE_API_KEY') or a fallback test key. Additionally,
enhance the mock auth object in the JSON.stringify call to include the missing
Firebase fields: add a refreshToken property with a mock value, and add an
expiresIn property set to '3600' to make the mock auth object more complete and
aligned with Firebase's actual auth token structure.

The mocked enhance endpoint has an incorrect route that won't match the actual frontend API call.

The test intercepts POST /api/enhance/mock-resume-uuid-456, but the frontend's enhanceApi.enhance() calls POST /api/enhance with resumeText and preferences in the request body (no ID in the URL path). The resume ID from the upload response isn't used in the enhance endpoint call—it's only used for frontend routing.

Update the intercept to match the actual API route:

Proposed fix
-    cy.intercept('POST', '/api/enhance/mock-resume-uuid-456', {
+    cy.intercept('POST', '/api/enhance', {
       statusCode: 200,
       body: {

Create the missing test fixture file and fixtures directory.

The test references cypress/fixtures/test-resume.pdf but the fixtures directory does not exist in the repository, and the file is missing. This will cause the test to fail when executed. Create the frontend/cypress/fixtures/ directory and add the required test-resume.pdf file.

🌐 Web query:

Firebase Auth onAuthStateChanged localStorage key format persistence

💡 Result:

Firebase Authentication uses browser storage (localStorage by default in web environments) to persist user authentication state across page reloads [1][2]. Storage Key Format When using the default LOCAL persistence, the Firebase Authentication SDK stores the user's session data in localStorage using a specific key format [3][4]: firebase:authUser:{apiKey}:[DEFAULT] In this pattern: - {apiKey} is the Firebase project API key [5]. - [DEFAULT] refers to the Firebase app name (the default app instance is named "[DEFAULT]") [5][4]. Accessing Stored Data While you can manually retrieve this data using window.localStorage.getItem, it is considered an implementation detail of the Firebase SDK [4]. The Firebase team advises against relying on manual manipulation of these storage keys, as the internal structure or management of this data may change [4]. Instead, you should manage authentication state using the official Firebase Auth SDK methods, specifically onAuthStateChanged, which is designed to handle state retrieval, persistence, and updates automatically [2]. Persistence Options You can control how Firebase persists this state using the setPersistence method [1][6]: - browserLocalPersistence (default): Persists state even after the browser window is closed [1][6]. - browserSessionPersistence: Persists state only for the duration of the current session/tab [1][6]. - browserCookiePersistence: Available for hybrid rendering and middleware scenarios [6]. - none: Keeps authentication state only in memory, clearing it upon page refresh [1][7]. If you need to change the persistence type, you should call setPersistence before performing sign-in operations [1][2].

The localStorage key format is incorrect according to Firebase documentation. Update the key to include the API key.

Firebase Auth localStorage persistence uses the format 'firebase:authUser:{apiKey}:[DEFAULT]'. The current key 'firebase:authUser:' is missing the API key portion, which does not match Firebase's documented format.

Additionally, the mock auth object is incomplete. Real Firebase auth tokens include fields like refreshToken, expiresIn, stsTokenManager, and provider metadata that the simplified mock omits.

While the test may still function due to network mocking (cy.intercept for identitytoolkit/**), relying on direct localStorage manipulation is fragile. Update the command to use the correct key format:

Cypress.Commands.add('mockFirebaseAuth', () => {
  const apiKey = Cypress.env('VITE_FIREBASE_API_KEY') || 'AIzaSy_test_key';
  window.localStorage.setItem(
    `firebase:authUser:${apiKey}:[DEFAULT]`,
    JSON.stringify({
      uid: 'gssoc-test-user-123',
      email: 'testuser@gssoc.org',
      displayName: 'Test Contributor',
      token: 'mock-session-jwt-token',
      refreshToken: 'mock-refresh-token',
      expiresIn: '3600'
    })
  );
});

In `@frontend/cypress/support/commands.js` around lines 3 - 11, Update the
localStorage key in the command to match Firebase's documented format by
including the API key and [DEFAULT] suffix. Replace the static key
'firebase:authUser:' with a dynamic key that uses the format
'firebase:authUser:{apiKey}:[DEFAULT]' where the apiKey is retrieved from
Cypress.env('VITE_FIREBASE_API_KEY') or a fallback test key. Additionally,
enhance the mock auth object in the JSON.stringify call to include the missing
Firebase fields: add a refreshToken property with a mock value, and add an
expiresIn property set to '3600' to make the mock auth object more complete and
aligned with Firebase's actual auth token structure.

Suggestion: The /api/upload mock response shape is incompatible with the upload page logic, which reads response.data.extractedText; returning only { success, id } causes downstream extractedText access to break and abort navigation. Mock the same schema the UI consumes. [api mismatch]

Severity Level: Critical 🚨
- ❌ Upload-to-resume creation flow crashes in Cypress runs.
- ❌ Enhance page is never navigated to in the test.
- ⚠️ Backend `/api/resumes` and enhance logic remain untested.
Steps of Reproduction ✅
1. The upload page logic in `frontend/src/pages/Upload.jsx:26-52` handles file selection;
it calls `const response = await uploadApi.uploadPdf(selectedFile, ...)` and then reads
`const extractedText = response.data.extractedText`.

2. `uploadApi.uploadPdf` in `frontend/src/services/api.js:160-181` performs a
`fetch(`${API_BASE}/upload`, { method: 'POST', ... })` and passes the HTTP response into
`handleResponse`, which returns the parsed JSON body (no additional wrapping).

3. The real backend upload route `backend/src/routes/upload.js:12-35` responds with `{
success: true, data: { resumeId, extractedText, ... } }`, so in production `response.data`
is an object containing `extractedText`.

4. In the Cypress test setup at `resume-flow.cy.js:9-12`, `cy.intercept('POST',
'/api/upload', { statusCode: 200, body: { success: true, id: 'mock-resume-uuid-456' } })`
returns a JSON shape without a `data` field; when the app under test runs
`Upload.jsx:34-35`, `response.data` is `undefined`, so `response.data.extractedText`
throws a `TypeError`, the catch block at lines 55-63 triggers a toast error, and
navigation to `/enhance/...` (lines 50-53) never occurs, causing the E2E test to fail
before the enhance page is reached.

Suggestion: This test waits for /api/enhance/mock-resume-uuid-456, but the app's enhance page uses different endpoints (e.g. /api/enhance/ats-analysis, /api/enhance/comprehensive-analysis, /api/enhance/stream), so the alias is never triggered and cy.wait('@enhanceResume') will time out. Intercept the real enhance endpoints the page actually calls. [api mismatch]

Severity Level: Critical 🚨
- ❌ Enhance-stage wait always times out in Cypress.
- ⚠️ Score ring and text assertions are never reached.
Steps of Reproduction ✅
1. After upload and resume creation, `Upload.jsx:50-53` redirects the user to
`/enhance/${resumeResponse.data.id}`, so the app renders
`frontend/src/pages/Enhance.jsx:98-245` for the enhance dashboard.

2. The enhance page issues multiple enhance-related API calls through `enhanceApi` in
`frontend/src/services/api.js:234-107`, including `POST /api/enhance/ats-analysis`, `POST
/api/enhance/comprehensive-analysis`, `POST /api/enhance/resume-score`, and a streaming
`POST /api/enhance/stream` (see `Enhance.jsx:150-198` and `Enhance.jsx:236-275`).

3. None of the frontend code calls `POST /api/enhance/:id`; instead, endpoints are fixed
subpaths like `/ats-analysis`, `/comprehensive-analysis`, `/resume-score`,
`/before-after`, `/verb-lists`, etc.

4. In the Cypress test, the only enhance-related intercept is `cy.intercept('POST',
'/api/enhance/mock-resume-uuid-456', ...)` at `resume-flow.cy.js:14-24`, aliased as
`@enhanceResume`, and the test later runs `cy.wait('@enhanceResume')` at line 46; because
the app never issues a request matching `/api/enhance/mock-resume-uuid-456`, this alias is
never hit and `cy.wait('@enhanceResume')` will eventually time out, failing the test even
if the enhance page loads correctly.

Suggestion: The test targets a dropzone element by data-testid="dropzone", but the upload UI does not expose that attribute, so this selector will fail and stop the flow. Use a selector that exists in the rendered DropZone markup or add a stable test id in the component. [api mismatch]

Severity Level: Major ⚠️
- ❌ Resume E2E test fails before simulating file upload.
- ⚠️ Resume upload flow is never exercised in Cypress runs.
Steps of Reproduction ✅
1. Run the Cypress E2E suite so that `frontend/cypress/e2e/resume-flow.cy.js:1-51`
executes the `"End-to-End Resume Enhancement User Journey"` spec.

2. In `beforeEach` (lines 2-29), the test boots the app via `cy.visit('/')`, then in the
test body navigates to `/dashboard` with `cy.visit('/dashboard')` at line 33.

3. The tested upload UI is implemented by `DropZone` in
`frontend/src/components/DropZone.jsx:84-142`; this component's root `<div>` (lines 87-99)
is built from `getRootProps()` but has no `data-testid="dropzone"` attribute anywhere in
the file.

4. When `cy.get('[data-testid="dropzone"]')` at `resume-flow.cy.js:37` runs, Cypress
queries the DOM for an element that does not exist, causing the command (and thus the
test) to time out and fail before any file selection or network assertions execute.

Suggestion: The referenced fixture file path does not exist in the Cypress fixtures directory in this PR, so file selection will fail before upload assertions run. Add the fixture file (or use an existing one) and ensure the path is valid. [possible bug]

Severity Level: Major ⚠️
- ❌ File upload cannot be simulated in E2E tests.
- ⚠️ Upload UI and routing assertions never execute.
Steps of Reproduction ✅
1. Run the Cypress E2E suite so that `frontend/cypress/e2e/resume-flow.cy.js:31-50`
executes the resume flow test.

2. After locating the (non-existent) dropzone, the test attempts to select a fixture via
`.selectFile('cypress/fixtures/test-resume.pdf', { action: 'drag-drop' })` at line 39.

3. The frontend Cypress project structure under `frontend/cypress` contains only `e2e/`
and `support/` directories (see `frontend/cypress` listing); there is no
`frontend/cypress/fixtures` directory and no `test-resume.pdf` anywhere in the repo.

4. Once the selector issue at line 37 is fixed, Cypress will attempt to read
`cypress/fixtures/test-resume.pdf` and fail with a "file not found" error, preventing the
drag-drop simulation and aborting the test before `/api/upload` is hit.

Suggestion: This writes to window.localStorage from the spec context, not the app-under-test window, so the app often won't see the mocked session. Set storage through the AUT window (for example via a cy.visit(..., { onBeforeLoad }) or cy.window() flow) so authentication state is applied to the actual app context. [api mismatch]

Severity Level: Major ⚠️
- ⚠️ Firebase auth mocking may not affect the AUT window.
- ⚠️ Auth-dependent API calls can fail in non-DEV E2E runs.
Steps of Reproduction ✅
1. The custom command `mockFirebaseAuth` is defined in
`frontend/cypress/support/commands.js:1-12` and wired into Cypress via
`frontend/cypress/support/e2e.js:1` (which imports `./commands`).

2. Each E2E test in `frontend/cypress/e2e/resume-flow.cy.js:2-29` calls
`cy.mockFirebaseAuth()` before `cy.visit('/')`, relying on it to seed a logged-in Firebase
session.

3. Inside the command, `window.localStorage.setItem(...)` at line 3 writes into the
spec-runner window's storage, not the app-under-test (AUT) window that hosts
`http://localhost:5173` where `auth` from `frontend/src/config/firebase.js:20-41` is
initialized.

4. In environments where `isFirebaseConfigValid` is true and `import.meta.env.DEV` is
false (so `getAuthHeaders` in `frontend/src/services/api.js:8-27` requires a real
`auth.currentUser`), the AUT's Firebase auth instance will not see the spec window's
localStorage, leaving `auth.currentUser` null and causing `getAuthHeaders` and
`uploadApi.uploadPdf` to throw `Not authenticated` errors despite `cy.mockFirebaseAuth()`
having been called.

Suggestion: The mocked Firebase persistence key is incomplete (firebase:authUser:), while Firebase auth persistence uses a fully qualified key format tied to app config; this value will not be picked up as a valid logged-in session. Use the same storage key/shape that Firebase actually persists for this app. [api mismatch]

Severity Level: Major ⚠️
- ⚠️ Firebase auth session mock is never picked up by SDK.
- ⚠️ Auth-dependent routes may be inaccessible in E2E tests.
Steps of Reproduction ✅
1. The custom auth-mocking command in `frontend/cypress/support/commands.js:1-12` uses
`window.localStorage.setItem('firebase:authUser:', JSON.stringify({ uid, email, ... }))`
at line 4 to simulate a persisted Firebase session.

2. Firebase initialization in `frontend/src/config/firebase.js:20-41` creates a real
`auth` instance via `getAuth(app)` when a valid config is present, and the Firebase SDK
expects its persisted auth state under keys like `firebase:authUser:<apiKey>:[DEFAULT]`
rather than the bare `'firebase:authUser:'` prefix.

3. Because no code in the repo reads from `'firebase:authUser:'` (the only occurrence is
this mock command), and the Firebase SDK uses its own fully-qualified key format, writing
the mock user under `'firebase:authUser:'` never hydrates `auth.currentUser`.

4. In any Cypress run where `isFirebaseConfigValid` in `config/firebase.js` is true and
`import.meta.env.DEV` is false (so `getAuthHeaders` in `frontend/src/services/api.js:8-27`
and `uploadApi.uploadPdf` in lines 160-181 require an authenticated `auth.currentUser`),
the incorrect key prevents Firebase from restoring a logged-in user, leading to `Not
authenticated` errors even though `cy.mockFirebaseAuth()` has executed.
