# Firestore Client Integration Tests

These tests perform real GCP Firestore operations to comprehensively test all Firestore functionality.
Tests follow the AGENTS.md guidelines with complete e2e lifecycle testing.

## Test Structure

1. **test_framework_setup_firestore** - Quick connectivity test (30 seconds)
2. **test_firestore_comprehensive_lifecycle** - Complete end-to-end lifecycle testing:
   - Database management (create, get, list, patch)
   - Field configuration and TTL setup
   - Document operations (CRUD, batch, field masks, preconditions)
   - Advanced features (transactions, queries, indexes)
   - Error scenarios (non-existent resources, invalid credentials, conflicts)

This consolidated approach reduces database creation from 10+ to 1, saving 45-60 minutes of test time
while providing comprehensive coverage of all Firestore functionality.

## Prerequisites

### 1. GCP Credentials
Set up `.env.test` in the workspace root with:
```
GOOGLE_MANAGEMENT_SERVICE_ACCOUNT_KEY={"type":"service_account",...}
```

### 2. Required Permissions
Your service account needs these permissions:
- `datastore.databases.create`
- `datastore.databases.delete`
- `datastore.databases.get`
- `datastore.databases.list`
- `datastore.entities.*`
- `datastore.operations.get`
- `datastore.fields.get`
- `datastore.fields.list`
- `datastore.fields.update`

## Running Tests
```bash
# Run all Firestore tests
cargo test --package alien-gcp-clients --test gcp_firestore_client_tests -- --nocapture

# Run specific test
cargo test --package alien-gcp-clients --test gcp_firestore_client_tests test_firestore_comprehensive_lifecycle -- --nocapture
```

All tests work with real GCP resources and will fail if operations don't succeed.
