# AgMission Test Runner Guide

## Overview

The AgMission test suite consists of **standalone integration test scripts** organized into feature-based categories. These are **not** traditional unit tests - they are full integration tests that connect to real services (MongoDB, Stripe, RabbitMQ, Partner APIs).

## Test Organization

Tests are organized in feature-based directories:

```
tests/
├── dlq/              - Dead Letter Queue tests (3 files)
├── integration/      - Cross-feature integration (2 files)
├── job/              - Job processing tests (9 files)
├── parsing/          - Log parsing tests (7 files)
├── payment/          - Payment & billing (4 files)
├── promo/            - Promotion & coupon (13 files)
├── satloc/           - Partner integration (13 files)
├── utils/            - Utility tests (9 files)
└── run_all_tests.js  - Test runner script
```

## Running Tests

### Run All Tests
```bash
npm run test:all
```

### Run Tests by Category
```bash
npm run test:promo      # Promotion/coupon tests
npm run test:satloc     # SatLoc partner tests
npm run test:job        # Job processing tests
npm run test:payment    # Payment & billing tests
npm run test:dlq        # DLQ management tests
npm run test:parsing    # Log parsing tests
npm run test:integration # Integration tests
npm run test:utils      # Utility tests
```

### Run Single Test File
```bash
npm run test:single tests/promo/test_promo_details.js
```

Or directly with node:
```bash
node tests/promo/test_promo_details.js
```

### Run Tests with Options
```bash
# Verbose output (show all test output)
npm run test:verbose

# Stop on first failure
npm run test:bail

# Run specific pattern
npm run test:file 'promo/test_promo_*.js'

# Run with custom pattern
node tests/run_all_tests.js --pattern 'job/test_*.js'

# Run single category with verbose output
node tests/run_all_tests.js --pattern 'dlq/test_*.js' --verbose
```

## Test Runner Features

The custom test runner (`tests/run_all_tests.js`) provides:

### ✅ Separate Process Execution
- Each test runs in its own Node.js process
- Handles `process.exit()` calls gracefully
- Isolated test environments prevent interference

### 📊 Pass/Fail Reporting
- Reports ✅ PASSED or ❌ FAILED for each test
- Exit code 0 = test passed
- Exit code non-zero = test failed
- Summary shows passed/failed counts

### ⏱️ Duration Tracking
- Individual test duration in milliseconds
- Total test suite duration in seconds

### 🛑 Stop on Failure
- Use `--bail` flag to stop after first failure
- Useful for quick failure detection

### 📢 Verbose Mode
- Use `--verbose` flag to see all test output
- Default: only shows output for failed tests

## Understanding Test Results

### Exit Codes
- **0**: Test completed successfully (PASSED)
- **1**: Test failed or encountered errors (FAILED)
- **Other**: Process crashed or was terminated

### Test Failures
When a test fails:
1. Check the exit code (usually 1 for logical failures)
2. Review the output preview (last 5 lines shown by default)
3. Re-run with `--verbose` to see full output
4. Check test file directly for assertions and logic

### Common Failure Reasons
- ❌ Service connectivity (MongoDB, Redis, RabbitMQ not running)
- ❌ API authentication (Stripe key invalid, partner credentials wrong)
- ❌ Environment variables missing or incorrect
- ❌ Test data conflicts (duplicate records, outdated IDs)
- ❌ Network timeouts or rate limits

## Environment Configuration

Tests use `environment.env` by default:

```bash
# Use custom environment file
node tests/run_all_tests.js --env ./environment_prod.env

# Test runner auto-loads environment variables
```

**Important**: Tests are **integration tests** that connect to real services. Ensure:
- MongoDB is running and accessible
- Redis is running (if tests use caching)
- RabbitMQ is running (for queue tests)
- Stripe API keys are valid (for payment tests)
- Partner API credentials are configured (for partner tests)

## Test Types

### Integration Tests
Files in `tests/` are **integration tests** that:
- Connect to real databases (MongoDB)
- Call external APIs (Stripe, partner APIs)
- Use message queues (RabbitMQ)
- Test end-to-end workflows

**Note**: These are NOT mocked unit tests. They require services to be running.

### Mocha Tests (Optional)
For traditional Mocha/Chai unit tests, create files with `.spec.js` extension:
```bash
tests/promo/promo_validation.spec.js
```

Run Mocha tests:
```bash
npm test              # Run all *.spec.js files
npm run test:mocha    # Same as above
```

## Best Practices

### Writing New Tests
1. **Use unique identifiers**: Add timestamps to avoid conflicts
   ```javascript
   const testId = Date.now();
   const promoName = `TestPromo_${testId}`;
   ```

2. **Track created resources**: Clean up only what you create
   ```javascript
   const createdIds = [];
   // ... create resources, track IDs
   // Cleanup at end
   for (const id of createdIds) {
     await deleteResource(id);
   }
   ```

3. **Handle rate limits**: Add delays between API calls
   ```javascript
   await sleep(100); // 100ms delay between calls
   ```

4. **Return proper exit codes**:
   ```javascript
   if (allTestsPassed) {
     process.exit(0);
   } else {
     console.error('Tests failed');
     process.exit(1);
   }
   ```

5. **Load environment properly** (at top of file):
   ```javascript
   const path = require('path');
   const envPath = path.resolve(process.cwd(), './environment.env');
   require('dotenv').config({ path: envPath });
   ```

### Naming Conventions
- Test files: `test_*.js` (e.g., `test_promo_details.js`)
- Manual scripts: `manual_*.js` (excluded from test runs)
- Mocha tests: `*.spec.js` (run separately via npm test)

### Debugging Failing Tests
1. Run with verbose output:
   ```bash
   node tests/run_all_tests.js --pattern 'dlq/test_*.js' --verbose
   ```

2. Run single test directly:
   ```bash
   node tests/dlq/test_dlq_routes.js
   ```

3. Check services are running:
   ```bash
   # MongoDB
   systemctl status mongod
   
   # RabbitMQ
   systemctl status rabbitmq-server
   
   # Redis
   systemctl status redis
   ```

4. Verify environment variables:
   ```bash
   cat environment.env | grep STRIPE
   cat environment.env | grep MONGO
   ```

## Migration Notes

Tests were migrated from flat directory structure to feature-based organization:
- See `TESTS_ORGANIZED.md` for migration details
- All relative imports were updated automatically
- Tests maintain original functionality

## Summary

**Key Points**:
- ✅ Tests organized by feature in subdirectories
- ✅ Custom test runner executes and reports results
- ✅ Each test runs in isolated process
- ✅ Pass/fail tracking with duration metrics
- ✅ Integration tests require real services
- ✅ Use npm scripts for organized test execution
- ✅ Support for verbose output and stop-on-failure

**Quick Start**:
```bash
# Run all tests
npm run test:all

# Run category
npm run test:promo

# Run single test
npm run test:single tests/promo/test_promo_details.js

# Verbose output
npm run test:verbose

# Stop on first failure
npm run test:bail
```
