# Admin User Management Integration Tests

This directory contains integration tests for admin user management functionality that use **real AWS Cognito and Permit.io APIs** (no mocks).

## Overview

These tests validate the complete user management workflow including:
- User creation in AWS Cognito and Permit.io
- User retrieval and attribute updates
- User enable/disable operations
- User deletion from both systems
- Role assignment and unassignment in Permit.io
- User listing with pagination
- Idempotent operations

## Why Integration Tests Are Separate

The admin user management code is **excluded from standard CI/CD coverage requirements** because:
1. Free tier LocalStack doesn't support AWS Cognito
2. Integration tests require real AWS credentials
3. Integration tests require real Permit.io API access
4. Tests create and modify real user accounts
5. Tests should not run automatically in CI/CD pipelines

These tests are designed for **manual execution** during development and pre-production validation.

## Prerequisites

### AWS Requirements
use `task aws:login` then 
`eval $(aws configure export-credentials --profile aarete --format env)`
to set fresh credentials for the test to use. 


1. **AWS Account** with access to Cognito User Pool
2. **IAM User or Role** with the following permissions:
   ```json
   {
     "Version": "2012-10-17",
     "Statement": [
       {
         "Effect": "Allow",
         "Action": [
           "cognito-idp:AdminCreateUser",
           "cognito-idp:AdminDeleteUser",
           "cognito-idp:AdminGetUser",
           "cognito-idp:AdminUpdateUserAttributes",
           "cognito-idp:AdminDisableUser",
           "cognito-idp:AdminEnableUser",
           "cognito-idp:ListUsers"
         ],
         "Resource": "arn:aws:cognito-idp:REGION:ACCOUNT_ID:userpool/POOL_ID"
       }
     ]
   }
   ```

3. **Cognito User Pool ID** - Get this from AWS Console or CLI

### Permit.io Requirements

1. **Permit.io Account** with API access
2. **API Key** with permissions to:
   - Create users
   - Delete users
   - Assign/unassign roles
   - Read user roles
3. **Project ID** and **Environment ID** from Permit.io dashboard
4. **Roles configured** in Permit.io matching your `permit_policies.yaml`:
   - `super_admin`
   - `user_admin`
   - `auditor`
   - `client_user`

## Setup Instructions

### Step 1: Create Environment File

```bash
cd test/integration
cp .env.example .env
```

### Step 2: Configure Credentials

Edit `test/integration/.env` and fill in your actual credentials:

```bash
# AWS Configuration
AWS_REGION=us-east-1
AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
COGNITO_USER_POOL_ID=us-east-1_AbCdEfGhI

# Suppress welcome emails to avoid AWS Cognito's 50 emails/day limit
COGNITO_SUPPRESS_EMAILS=true

# Skip Permit.io cleanup (set to true to inspect users after tests)
SKIP_PERMITIO_CLEANUP=false

# Permit.io Configuration
PERMIT_IO_API_KEY=permit_key_1234567890abcdef
PERMIT_IO_PROJECT_ID=my-project-123
PERMIT_IO_ENV_ID=dev
PERMIT_IO_TENANT=default

# Test Configuration
TEST_USER_EMAIL_PREFIX=int-test-
TEST_USER_DOMAIN=example.com
```

**IMPORTANT:** Never commit the `.env` file to git! It contains sensitive credentials.

### Step 3: Verify Permit.io Roles

**Note:** The test suite automatically loads environment variables from `test/integration/.env` when you run the tests. You do NOT need to manually source the file.

Ensure the following roles exist in your Permit.io environment (as defined in `cmd/auth_related/permit.setup/permit_policies.yaml`):
- `super_admin`
- `user_admin`
- `auditor`
- `client_user`

You can create roles through the Permit.io dashboard, API, or use the setup tool at `cmd/auth_related/permit.setup/`.

## Running the Tests

### Run All Integration Tests (13 total)

```bash
go test -tags=integration -v ./test/integration/...
```

This runs:
- **8 integrated tests** (Cognito + Permit.io)
- **5 Permit.io-only tests** (no Cognito calls)

### Run Only Integrated Tests (Cognito + Permit.io)

```bash
go test -tags=integration -v -run 'TestSuite/Test[^P]' ./test/integration/...
```

This excludes tests starting with `TestPermitIO_`.

### Run Only Permit.io Tests (No Cognito)

```bash
go test -tags=integration -v -run 'TestSuite/TestPermitIO' ./test/integration/...
```

Useful when you've hit AWS Cognito's email limit or want to test Permit.io in isolation.

### Run a Specific Test

```bash
go test -tags=integration -v -run TestSuite/TestCreateUser ./test/integration/...
```

### Run via Task Command

Add this task to your Taskfile.yml:

```yaml
integration:admin:
  desc: "Run admin user management integration tests (requires real AWS/Permit.io credentials)"
  dir: test/integration
  cmds:
    - |
      if [ ! -f .env ]; then
        echo "❌ Error: test/integration/.env not found"
        echo "Copy .env.example to .env and configure your credentials"
        exit 1
      fi
    - go test -tags=integration -v ./...
```

Then run:

```bash
task integration:admin
```

## Test Coverage

The test suite includes **13 integration tests** organized into two categories:

### Integrated Tests (8 tests - Cognito + Permit.io)

These tests validate the complete user management workflow across both systems:

| Test | Description |
|------|-------------|
| `TestCreateUser` | Creates a new user in both Cognito and Permit.io |
| `TestCreateUserIdempotent` | Verifies idempotent user creation behavior |
| `TestGetUser` | Retrieves an existing user's details from Cognito |
| `TestUpdateUserAttributes` | Updates user's first name and last name in Cognito |
| `TestDisableEnableUser` | Disables and re-enables a user account in Cognito |
| `TestDeleteUser` | Deletes user from both Cognito and Permit.io |
| `TestListUsers` | Lists users with pagination support from Cognito |
| `TestRoleAssignment` | Assigns and unassigns roles in Permit.io for Cognito user |

**Note:** These tests require AWS credentials and will send emails unless `COGNITO_SUPPRESS_EMAILS=true`.

### Permit.io-Only Tests (5 tests - No Cognito)

These tests validate Permit.io functionality in isolation using generated UUIDs:

| Test | Description |
|------|-------------|
| `TestPermitIO_CreateAndGetUser` | Creates user in Permit.io and verifies it exists |
| `TestPermitIO_AssignMultipleRoles` | Assigns/unassigns multiple roles (auditor, client_user) |
| `TestPermitIO_DeleteUser` | Deletes user and verifies with 404 response |
| `TestPermitIO_UserLifecycle` | Complete 9-step user lifecycle (create → roles → delete) |
| `TestPermitIO_IdempotentOperations` | Tests duplicate user/role operations are idempotent |

**Note:** These tests do NOT call AWS Cognito and can run unlimited times per day.

## Test User Management

### Automatic Cleanup

The test suite implements automatic cleanup in the `TearDownSuite` method:
- All test users are tracked during creation
- After all tests complete, users are automatically deleted from both Cognito and Permit.io
- If cleanup fails, warnings are logged but tests still pass
- **Optional:** Set `SKIP_PERMITIO_CLEANUP=true` to preserve Permit.io users for manual inspection (see "Manual Inspection of Test Users" section)

### Manual Cleanup

If tests are interrupted and cleanup doesn't run:

```bash
# List users in Cognito
aws cognito-idp list-users --user-pool-id YOUR_POOL_ID

# Delete a user from Cognito
aws cognito-idp admin-delete-user \
  --user-pool-id YOUR_POOL_ID \
  --username user@example.com

# Delete from Permit.io (requires API call)
curl -X DELETE \
  "https://api.permit.io/v2/facts/PROJECT_ID/ENV_ID/users/SUBJECT_ID" \
  -H "Authorization: Bearer YOUR_API_KEY"
```

### Test Email Format

Test users are created with emails in this format:
```
{PREFIX}{TEST_NAME}-{TIMESTAMP}@{DOMAIN}
```

Examples:
- Integrated test: `int-test-create-1697123456@example.com`
- Permit.io test: `int-test-permitio-create-1697123456@example.com`

This makes it easy to identify and clean up test users. You can customize the prefix and domain using environment variables:
- `TEST_USER_EMAIL_PREFIX` (default: `int-test-`)
- `TEST_USER_DOMAIN` (default: `example.com`)

## AWS Cognito Email Limits

AWS Cognito has a **daily limit of 50 emails** when using the default email service. This limit:
- Applies to welcome emails sent during user creation
- Resets daily at **09:00 UTC**
- Is shared across **all user pools** in your AWS account
- Cannot be increased without configuring Amazon SES

### Email Suppression for Testing

To avoid hitting this limit during integration testing, the test suite uses the `COGNITO_SUPPRESS_EMAILS=true` environment variable. When set:

- ✅ No welcome emails are sent to test users
- ✅ Users are still created successfully with `email_verified: true`
- ✅ Tests can run unlimited times per day
- ✅ All user management operations work normally

**This is the recommended approach for integration tests.**

### If You Need to Test Email Delivery

For production environments or when you need to test actual email delivery:

1. **Configure Amazon SES** with your Cognito User Pool
2. **Move SES out of sandbox mode** (requires AWS support ticket, 24hr response)
3. **Email limits increase to 50,000/day** in SES production mode

See [AWS Cognito Email Settings Documentation](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-email.html) for setup instructions.

## Manual Inspection of Test Users

To inspect users created during tests in the Permit.io dashboard:

1. **Set the skip cleanup flag** in `test/integration/.env`:
   ```bash
   SKIP_PERMITIO_CLEANUP=true
   ```

2. **Run the Permit.io-only tests:**
   ```bash
   go test -tags=integration -v -run 'TestSuite/TestPermitIO' ./test/integration/...
   ```

3. **Check test output** for user details:
   ```
   🔵 Permit.io-only user (SubjectID: cbfc1ba6-81a1-40e1-8e4d-14950737c08f)
   ✅ User found in Permit.io:
      - Roles: [auditor]
   ⏭️  Skipping Permit.io cleanup - user left for manual inspection
   ```

4. **Log into Permit.io dashboard** and inspect the users with the SubjectIDs from the test output

5. **Clean up manually** when done:
   - In Permit.io UI: Delete the test users
   - Or re-run tests with `SKIP_PERMITIO_CLEANUP=false`

**Note:** Cognito users (if any) are still cleaned up automatically to avoid AWS resource charges. Only Permit.io users are preserved when this flag is set.

## Troubleshooting

### Error: Required environment variable not set

**Solution:** Ensure all required variables are set in `test/integration/.env`

### Error: User pool not found

**Solution:** Verify `COGNITO_USER_POOL_ID` is correct and your AWS credentials have access

### Error: Permit.io API authentication failed

**Solution:**
- Verify `PERMIT_IO_API_KEY` is correct
- Check that the API key has not expired
- Ensure the API key has correct permissions

### Error: Role not found in Permit.io

**Solution:** Create the required roles in your Permit.io environment or update test to use existing roles

### Error: LimitExceededException - Exceeded daily email limit

```
api error LimitExceededException: Exceeded daily email limit for the operation or the account.
```

**Solution:**
- Ensure `COGNITO_SUPPRESS_EMAILS=true` is set in `test/integration/.env`
- The email limit resets at 09:00 UTC each day
- For production use, configure Amazon SES with your user pool (see AWS Cognito Email Limits section above)

### Tests hang or timeout

**Solution:**
- Check network connectivity to AWS and Permit.io
- Verify AWS credentials are not expired (especially for SSO/temporary credentials)
- Increase timeout if needed (edit `httpClient.Timeout` in test suite)

### Cleanup warnings

**Solution:** Warnings during cleanup are usually okay (e.g., user already deleted). However, if you see many failures:
- Check AWS credentials are still valid
- Verify Permit.io API key permissions
- Manually clean up orphaned test users

## CI/CD Exclusion

The admin handler code is **intentionally excluded** from CI/CD coverage checks:

**Excluded files in `scripts/tests.yml`:**
- `api/queryAPI/adminHandlers.go`
- `internal/usermanagement/audit.go`
- `internal/usermanagement/cognito.go`
- `internal/usermanagement/permitio.go`
- `internal/usermanagement/types.go`

This allows the main test suite to pass without requiring cloud credentials.

## Security Considerations

1. **Never commit credentials** - The `.env` file is gitignored
2. **Use test environments** - Don't run against production Cognito/Permit.io
3. **Limit IAM permissions** - Use least privilege for test credentials
4. **Rotate credentials** - Regularly rotate API keys and access keys
5. **Monitor test accounts** - Review test user creation in CloudWatch/Permit.io logs
6. **Clean up regularly** - Ensure test users are deleted after runs

## Future Enhancements

Potential improvements for the integration test suite:

- [ ] Add tests for concurrent user operations
- [ ] Test bulk user creation/deletion
- [ ] Add tests for edge cases (special characters in names, etc.)
- [ ] Test Cognito password reset flow
- [ ] Test MFA enrollment/verification
- [ ] Add performance benchmarks
- [ ] Test rate limiting behavior
- [ ] Add tests for invalid/malformed requests
- [ ] Test permission boundary scenarios in Permit.io
- [ ] Add chaos testing (network failures, timeouts, etc.)
