+# JWT Test Fixtures Setup Guide
+
+This guide explains how to configure JWT test fixtures for local development and CI/CD environments.
+
+## Overview
+
+The JWT authentication tests use a test RSA **public** key in `cypress/fixtures/jwt-keys.json`. Token **signing** uses the matching private key supplied at runtime via `TEST_JWT_PRIVATE_KEY` (env or CI). The private key is **never** committed to the repository.
+
+## Test Key Files
+
+### `cypress/fixtures/jwt-keys.json`
+
+Contains **only** the test RSA **public** key (2048-bit), used for reference and by `loadJWTKeys()`:
+
+- `publicKey`: Used by the app (via `NEXT_PUBLIC_JWT_PUBLIC_KEY`) to verify JWT tokens in tests.
+
+**No `privateKey`** is stored in the fixture. Signing is done in Cypress Node tasks using `TEST_JWT_PRIVATE_KEY`.
+
+### Credential rotation
+
+**The key pair previously stored here was committed (including the private key) and must be treated as compromised.** Rotate credentials:
+
+1. Generate a new RSA key pair:
+2. Update `NEXT_PUBLIC_JWT_PUBLIC_KEY` and `TEST_JWT_PRIVATE_KEY` (and CI secrets) with the new pair.
+3. Update `jwt-keys.json` with the new **public** key only.
+4. **Never** commit the new private key.
+
+## Local Development Setup
+
+### 1. Configure Environment Variables
+
+Create or update your `.env` file:
+
+```bash
+# Public key — app uses this to verify tokens (must match private key used for signing)
+NEXT_PUBLIC_JWT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----
+MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAj760PNWDk5AWonv/G63Q
+08b1XAqUdCVttXLxr6AEXcJeYWXwDPRZAGKBpMTVcu0SIl7I958ebVx2A1I4dNAZ

+rufZNFqMGjlUzmH5KYr4CcnuzYFTN0RxUJrCs1UDh/KbI2wZx3ZXXt4zp4QQNAO0
+RQIDAQAB
+-----END PUBLIC KEY-----"
+
+# Private key — used only by Cypress Node tasks to sign test tokens (never commit)
+# Must match the public key above. Omit to skip JWT auth tests that need valid tokens.
+TEST_JWT_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----
+...
+-----END PRIVATE KEY-----"
+```
+
+You can use the public key from `jwt-keys.json`. The private key must be the matching pair; obtain it from your team or generate a new pair and rotate (see above).
+
+### 2. Run Tests Locally
+
+```bash
+# Run all tests
+yarn cy:run
+
+# Run JWT-specific tests
+yarn cy:run --spec "cypress/e2e/jwtAuth.test.ts"
+
+# Run component tests with JWT
+yarn cy:run --component --spec "src/components/Header/NavRight.test.tsx"
+
+# Open Cypress UI for interactive testing
+yarn cy:open
+```
+
+## CI/CD Setup (GitHub Actions)
+
+### 1. Configure GitHub Secrets
+
+Add these **optional** secrets to run JWT authentication tests:
+
+**`NEXT_PUBLIC_JWT_PUBLIC_KEY`**
+The test RSA public key (must match `TEST_JWT_PRIVATE_KEY`).
+
+**`TEST_JWT_PRIVATE_KEY`**
+The matching test RSA private key. Used only by Cypress Node tasks for signing; never logged or committed.
+
+### 2. Workflow Configuration
+
+The workflow in `.github/workflows/cypress_tests.yml`:
+
+- Accepts `NEXT_PUBLIC_JWT_PUBLIC_KEY` and `TEST_JWT_PRIVATE_KEY` as optional secrets
+- Passes them to the test environment
+- Maps `CYPRESS_USER_COOKIE` to `Cypress.env('userCookie')`
+
+Cypress config sets `config.env.jwtPublicKey` and `jwtPublicKeyConfigured` **only** when `NEXT_PUBLIC_JWT_PUBLIC_KEY` is set. Tests that require valid JWTs skip when it is not configured.
+
+### 3. Existing Secrets
+
+The CI already uses:
+
+- `CYPRESS_USER_COOKIE`: Real user session cookie for integration tests
+- `CYPRESS_RECORD_KEY`: Cypress Dashboard recording
+- Other API URLs and config
+
+## JWT Test Helpers
+
+Helpers live in `cypress/support/jwt-helper.ts`. Signing and verification run in **Cypress Node tasks** (not in the browser).
+
+### `generateTestJWT(payload, expiresIn)`
+
+Generates a valid JWT via `cy.task('signJWT')` (uses `TEST_JWT_PRIVATE_KEY`):
+
+```typescript
+generateTestJWT({ uid: 'test-123', name: 'Test User' }).then((token) => {
+ // Use token in tests
+})
+```
+
+### `setAuthenticatedSession(user, expiresIn)`
+
+Sets up an authenticated session with a valid JWT:
+
+```typescript
+setAuthenticatedSession({ uid: 'test-123', name: 'Test User' })
+cy.visit('/')
+// User is now authenticated
+```
+
+### `generateExpiredTestJWT(payload)`
+
+Generates an expired JWT for error handling:
+
+```typescript
+generateExpiredTestJWT({ uid: 'test-123', name: 'Test User' }).then((token) => {
+ // Use expired token
+})
+```
+
+### `verifyTestJWT(token)`
+
+Verifies a JWT via `cy.task('verifyJWT')` (uses `NEXT_PUBLIC_JWT_PUBLIC_KEY`). Returns decoded payload or `null`.
+
+### `loadJWTKeys()`
+
+Returns `cy.fixture('jwt-keys')` (public key only). Use when you need the public key in spec context.
+
+## Test Behavior
+
+### When JWT is configured
+
+- `NEXT_PUBLIC_JWT_PUBLIC_KEY` is set → `jwtPublicKeyConfigured` is true.
+- `TEST_JWT_PRIVATE_KEY` is set → tasks can sign tokens.
+- Authenticated-user tests run; helpers generate valid JWTs.
+
+### When JWT is NOT configured
+
+- Tests that require valid JWTs skip (check `Cypress.env('jwtPublicKeyConfigured')`).
+- Error-handling tests (invalid tokens, missing cookies, etc.) still run.
+- Unauthenticated-user tests still run.
+
+## Security Notes
+
+- **`jwt-keys.json`**: Contains **only** the public key. Safe to commit.
+- **Private key**: Supplied via `TEST_JWT_PRIVATE_KEY` only. Never commit, never add to fixtures.
+- **Rotation**: If the previous test key pair was committed, rotate both keys and update env/secrets (see above).
+
+## Generating New Test Keys
+
+```bash
+node -e "
+const crypto = require('crypto');
+const { publicKey, privateKey } = crypto.generateKeyPairSync('rsa', {
+ modulusLength: 2048,
+ publicKeyEncoding: { type: 'spki', format: 'pem' },
+ privateKeyEncoding: { type: 'pkcs8', format: 'pem' }
+});
+console.log('PUBLIC_KEY:', publicKey);
+console.log('PRIVATE_KEY:', privateKey);
+"
+```
+
+Then:
+
+1. Update `jwt-keys.json` with the **public** key only.
+2. Set `NEXT_PUBLIC_JWT_PUBLIC_KEY` (e.g. in `.env`) to that public key.
+3. Set `TEST_JWT_PRIVATE_KEY` to the private key (env or CI secret). **Never commit it.**
+4. In CI, update `NEXT_PUBLIC_JWT_PUBLIC_KEY` and `TEST_JWT_PRIVATE_KEY` secrets.
+
+## Troubleshooting
+
+### Tests are skipped
+
+**Cause**: `NEXT_PUBLIC_JWT_PUBLIC_KEY` is not set.
+**Solution**: Set it (and `TEST_JWT_PRIVATE_KEY` for signing) as above.
+
+### JWT verification fails / "TEST_JWT_PRIVATE_KEY is required"
+
+**Cause**: Missing or mismatched keys.
+**Solution**: Ensure `NEXT_PUBLIC_JWT_PUBLIC_KEY` and `TEST_JWT_PRIVATE_KEY` are a matching pair.
+
+### Component tests can't find jwt-helper
+
+**Cause**: Import path.
+**Solution**: Use `../../../cypress/support/jwt-helper` from component test files.

+# JWT Test Fixtures - Implementation Summary
+
+## Problem Statement
+Previously, JWT authentication tests were commented out with notes like:
+- "These tests are commented out because they require a valid JWT token"
+- "This would require setting NEXT_PUBLIC_JWT_PUBLIC_KEY"
+- "Requires proper authentication setup which should be configured in CI/CD"
+
+## Solution Implemented
+
+### 1. Test Key Infrastructure
+Created a complete test key infrastructure that is:
+- **Safe to commit** (test-only keys, not production)
+- **Self-contained** (fixtures + helpers)
+- **CI/CD ready** (automatic environment setup)
+
+### 2. Files Structure
+
+```
+cypress/
+├── fixtures/
+│ ├── jwt-keys.json # Test RSA public key only (no private key)
+│ └── JWT_TEST_SETUP.md # Setup guide (NEW)
+├── support/
+│ ├── jwt-helper.ts # JWT utilities (NEW)
+│ └── e2e.ts # Updated to import helper
+└── e2e/
+ └── jwtAuth.test.ts # Tests now ENABLED
+
+src/components/Header/
+└── NavRight.test.tsx # Valid JWT test ENABLED
+
+.github/workflows/
+└── cypress_tests.yml # Added JWT_PUBLIC_KEY support
+
+cypress.config.ts # Env var mapping
+README.md # Quick start added
+.env.jwt-testing # Developer example (NEW)
+docs/JWT_TESTING.md # Updated docs
+```
+
+### 3. Developer Experience
+
+**Before:**
+```typescript
+// it('should display user name when authenticated', () => {
+// // Tests commented out - no way to generate valid tokens
+// })
+```
+
+**After:**
+```typescript
+import { setAuthenticatedSession } from '../support/jwt-helper'
+
+it('should display user name when authenticated', () => {
+ // Generate valid JWT using test fixtures
+ setAuthenticatedSession({ uid: 'test-123', name: 'Test User' })
+ cy.visit('/')
+ cy.get('#sign-in').should('be.visible')
+})
+```
+
+### 4. CI/CD Setup
+
+**Required for JWT tests:**
+Add GitHub secrets `NEXT_PUBLIC_JWT_PUBLIC_KEY` and `TEST_JWT_PRIVATE_KEY` (must be a matching RSA key pair). See `cypress/fixtures/JWT_TEST_SETUP.md` for key generation instructions.
+
+**How it works:**
+1. Workflow passes secrets to test environment
+2. Cypress config sets `jwtPublicKey` / `jwtPublicKeyConfigured` only when `NEXT_PUBLIC_JWT_PUBLIC_KEY` is set
+3. Cypress Node tasks sign tokens using `TEST_JWT_PRIVATE_KEY`, verify using `NEXT_PUBLIC_JWT_PUBLIC_KEY`
+4. App verifies tokens using `NEXT_PUBLIC_JWT_PUBLIC_KEY`
+5. Full authentication flow tested end-to-end
+
+### 5. Key Features
+
+#### Graceful Degradation
+```typescript
+if (!Cypress.env('jwtPublicKeyConfigured')) {
+ cy.log('Skipping: NEXT_PUBLIC_JWT_PUBLIC_KEY not configured for tests')
+ return
+}
+// Test runs with valid JWT...
+```
+
+#### Helper Functions
+```typescript
+// Generate valid JWT
+generateTestJWT({ uid: 'test-123', name: 'Test User' })
+
+// Set up authenticated session
+setAuthenticatedSession({ uid: 'test-123', name: 'Test User' })
+
+// Generate expired JWT for error testing
+generateExpiredTestJWT({ uid: 'test-123', name: 'Test User' })
+
+// Verify JWT
+verifyTestJWT(token)
+```
+
+#### Environment Mapping
+```typescript
+// In cypress.config.ts
+if (process.env.CYPRESS_USER_COOKIE) {
+ config.env.userCookie = process.env.CYPRESS_USER_COOKIE
+}
+
+if (process.env.NEXT_PUBLIC_JWT_PUBLIC_KEY) {
+ config.env.jwtPublicKey = process.env.NEXT_PUBLIC_JWT_PUBLIC_KEY.replace(/\\n/g, '\n')
+ config.env.jwtPublicKeyConfigured = true
+}
+
+if (process.env.TEST_JWT_PRIVATE_KEY) {
+ config.env.testJwtPrivateKey = process.env.TEST_JWT_PRIVATE_KEY.replace(/\\n/g, '\n')
+ config.env.testJwtPrivateKeyConfigured = true
+}
+```
+
+The cy.task handler used for JWT **sign** operations (the task name that signs tokens) should read **`config.env.testJwtPrivateKey`** when performing sign operations.
+
+**Where to look:**
+- **Task implementation (where the private key is consumed):** In `cypress.config.ts`, inside `setupJWTConfigAndTasks` — the `on('task', { signJWT, signExpiredJWT, verifyJWT })` handlers. The **sign** tasks (`signJWT`, `signExpiredJWT`) consume the private key for signing.
+- **Where the JWT sign/verify tasks are called:** In `cypress/support/jwt-helper.ts` — `generateTestJWT` and `generateExpiredTestJWT` call `cy.task('signJWT', ...)` and `cy.task('signExpiredJWT', ...)`; `verifyTestJWT` calls `cy.task('verifyJWT', ...)`.
+
+### 6. Security Guarantees
+
+| Aspect | Implementation |
+|--------|----------------|
+| **Test public key** | In `jwt-keys.json`; safe to commit |
+| **Test private key** | Via `TEST_JWT_PRIVATE_KEY` only; never in repo or fixtures |
+| **Production Keys** | Remain in secure secrets, never committed |
+| **Rotation** | If a private key was EVER committed to git history, it is permanently compromised. Rotate keys immediately and treat all tokens/data previously signed with that key as public knowledge. Consider the security impact on any systems that accepted those tokens. |
+
+### 7. Test Coverage Now Includes
+
+✅ **Unauthenticated users** (always ran)
+✅ **Invalid/malformed tokens** (always ran)
+✅ **Valid JWT authentication** (NOW ENABLED)
+✅ **User menu display** (NOW ENABLED)
+✅ **Authentication state** (NOW ENABLED)
+✅ **Component rendering with JWT** (NOW ENABLED)
+
+### 8. Usage Examples
+
+**Local Testing:**
+```bash
+# 1. Setup
+cp .env.jwt-testing .env
+# Uncomment the JWT_PUBLIC_KEY in .env
+
+# 2. Run tests
+yarn cy:run
+
+# 3. Run specific JWT tests
+yarn cy:run --spec "cypress/e2e/jwtAuth.test.ts"
+```
+
+**In Test Code:**
+```typescript
+describe('Authenticated Flow', () => {
+ beforeEach(() => {
+ // Set up authenticated session with valid JWT
+ setAuthenticatedSession({
+ uid: 'martin-fenner',
+ name: 'Martin Fenner'
+ })
+ })
+
+ it('shows user menu', () => {
+ cy.visit('/')
+ cy.get('#sign-in').should('be.visible')
+ cy.get('#sign-in').click()
+ cy.get('[data-cy=settings]').should('be.visible')
+ })
+})
+```
+
+### 9. Documentation
+
+Comprehensive documentation added:
+- **JWT_TEST_SETUP.md** - Complete setup guide with troubleshooting
+- **JWT_TESTING.md** - Updated with fixture information
+- **README.md** - Quick start section added
+- **Inline comments** - In all test files
+
+### 10. What's Different from Before
+
+| Aspect | Before | After |
+|--------|--------|-------|
+| **Valid JWT tests** | Commented out | ✅ Enabled |
+| **Test fixtures** | None | ✅ Complete infrastructure |
+| **JWT generation** | Manual/impossible | ✅ Automated helpers |
+| **CI/CD support** | Unclear | ✅ Documented & implemented |
+| **Local testing** | Difficult | ✅ Simple .env setup |
+| **Documentation** | Minimal | ✅ Comprehensive |
+
+## Result
+
+✅ All commented-out JWT tests are now enabled and functional
+✅ Complete test fixture infrastructure in place
+✅ CI/CD ready with optional configuration
+✅ Developer-friendly with example files and docs
+✅ Security-conscious with clear separation of test/prod keys
+✅ Zero breaking changes to existing tests

+# JWT Authentication Testing Documentation
+
+## Overview
+
+This document describes the JWT (JSON Web Token) authentication testing implementation for the Akita project. The tests ensure that JWT authentication is properly validated and handled across the application.
+
+## JWT Implementation
+
+The JWT authentication is implemented in `src/utils/session.ts`. This utility:
+
+1. Retrieves the JWT token from the `_datacite` cookie
+2. Verifies the token using the RSA public key (`NEXT_PUBLIC_JWT_PUBLIC_KEY`)
+3. Uses RS256 algorithm for verification
+4. Returns user information if the token is valid, otherwise returns null
+
+### Components Using JWT
+
+The following components use the `session()` function for authentication:
+
+- `src/components/Header/NavRight.tsx` - Displays signed-in/signed-out content
+- `src/components/Header/Dropdown.tsx` - User dropdown menu
+- `src/components/Header/ClientButtons.tsx` - Client-specific buttons
+- `src/components/Claim/Claim.tsx` - Claiming works to ORCID
+- `src/components/DiscoverWorksAlert/DiscoverWorksAlert.tsx` - Work discovery alerts
+
+## Test Coverage
+
+### E2E Tests (`cypress/e2e/jwtAuth.test.ts`)
+
+End-to-end tests that validate JWT authentication flows in the browser:
+
+#### Unauthenticated User Tests
+- Verifies sign-in link is visible when not authenticated
+- Confirms user menu is not shown without authentication
+
+#### Authenticated User Tests
+- Tests for authenticated users with valid JWT tokens
+- Tokens are generated via Cypress Node tasks using `TEST_JWT_PRIVATE_KEY`; public key from `NEXT_PUBLIC_JWT_PUBLIC_KEY`
+- Tests conditionally skip if `NEXT_PUBLIC_JWT_PUBLIC_KEY` is not configured (`jwtPublicKeyConfigured`)
+- Validates user menu display and authentication state
+
+#### Invalid JWT Token Tests
+- **Invalid token format**: Ensures app handles malformed tokens gracefully
+- **Malformed cookie**: Tests behavior with corrupted cookie data
+- **Missing access_token**: Verifies handling when token is absent from cookie structure
+
+#### JWT Verification Error Handling Tests
+- **Expired token**: Ensures app doesn't crash with expired tokens
+- **Corrupted token**: Validates graceful handling of corrupted token data
+
+#### Session Persistence Tests
+- **Cross-page navigation**: Verifies session persists across page changes
+- **Missing NEXT_PUBLIC_JWT_PUBLIC_KEY**: Tests behavior when environment variable is not configured
+
+### Component Tests (`src/components/Header/NavRight.test.tsx`)
+
+Component-level tests for the NavRight component that uses JWT authentication:
+
+#### Authentication State Tests
+- **No JWT token**: Shows signed-out content when no token is present
+- **NEXT_PUBLIC_JWT_PUBLIC_KEY not configured**: Handles missing environment variable
+- **Missing access_token**: Handles incomplete cookie structure
+- **Invalid JWT token**: Shows signed-out content for invalid tokens
+- **Malformed cookie data**: Gracefully handles corrupted cookie data
+- **Valid JWT token**: Shows signed-in content when valid token is present (requires test key setup)
+
+## Running the Tests
+
+### Running All Tests
+```bash
+yarn cy:run
+```
+
+### Running Specific Test Files
+```bash
+# E2E JWT tests
+yarn cy:run --spec "cypress/e2e/jwtAuth.test.ts"
+
+# Component tests
+yarn cy:run --component --spec "src/components/Header/NavRight.test.tsx"
+```
+
+### Interactive Test Runner
+```bash
+yarn cy:open
+```
+
+## Test Environment Setup
+
+### For Local Testing
+
+1. Set the JWT public key in `.env`:
+```bash
+NEXT_PUBLIC_JWT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----"
+```
+
+2. For tests that generate valid tokens, also set `TEST_JWT_PRIVATE_KEY` (matching pair). See `cypress/fixtures/JWT_TEST_SETUP.md`. The fixture `jwt-keys.json` contains **only** the public key; the private key is never committed.
+
+3. The test suite provides helper functions that use Cypress Node tasks to generate and verify JWTs:
+```typescript
+import { setAuthenticatedSession } from '../support/jwt-helper'
+
+// Set up authenticated session in tests
+setAuthenticatedSession({ uid: 'test-123', name: 'Test User' })
+```
+
+### For CI/CD
+
+Configure the following in your CI/CD environment:
+- `NEXT_PUBLIC_JWT_PUBLIC_KEY`: Test RSA public key for JWT verification (optional)
+- `TEST_JWT_PRIVATE_KEY`: Matching test RSA private key for signing (optional). Used only in Cypress Node tasks; never commit.
+- `CYPRESS_USER_COOKIE`: A real user cookie for integration tests (already configured)
+
+**Important**: `jwt-keys.json` holds only the public key. The private key is supplied via `TEST_JWT_PRIVATE_KEY`. Rotate credentials if the previous key pair was ever committed.
+
+For complete setup instructions, see: `cypress/fixtures/JWT_TEST_SETUP.md`
+
+## Security Considerations
+
+The tests validate several security aspects:
+
+1. **Token Verification**: Ensures only properly signed tokens are accepted
+2. **Expired Token Handling**: Confirms expired tokens are rejected
+3. **Malformed Data**: Tests graceful degradation with corrupted data
+4. **Missing Configuration**: Validates safe behavior without NEXT_PUBLIC_JWT_PUBLIC_KEY
+
+## Future Improvements
+
+1. **Add more authenticated flow tests**: Expand coverage to other components using `session()`
+2. **Token refresh testing**: If token refresh is implemented, add tests for that flow
+3. **Performance tests**: Validate JWT verification doesn't impact page load times
+4. **Security scanning**: Automated security checks for JWT implementation
