🐳 Docker Infrastructure

Simple MongoDB (Port 27017)

Image: mongo:7
User: admin
Password: testpass123
Database: testdb

MongoDB ReplicaSet (Ports 27018, 27019, 27020)

Image: mongo:7
3 nodes: mongo-rs1, mongo-rs2, mongo-rs3
ReplicaSet: rs0
User: admin
Password: testpass123

🚀 How to Run the Tests

Option 1: Automated script (RECOMMENDED)

# Navigate to directory
cd tests/mongodb-tests

# Run script that does everything automatically
./run-tests.sh

This will:

Start Docker Compose (Simple MongoDB + ReplicaSet)
Wait 15 seconds for ReplicaSet initialization
Run all tests

Option 2: Step by step

1. Install dependencies

npm install

2. Start MongoDB with Docker

npm run docker:init

3. Wait for ReplicaSet to be ready (~15 seconds)

# View logs
npm run docker:logs

Wait to see: ✅ Replica Set configured correctly

4. Run tests

npm test

🛠️ Useful Commands

View Docker logs

npm run docker:logs

Stop and clean containers

npm run docker:down

Restart from scratch

npm run docker:down
npm run docker:up
# Wait ~15 seconds
npm test

Connect to MongoDB with mongosh

mongosh "mongodb://admin:testpass123@localhost:27018,localhost:27019,localhost:27020/testdb?authSource=admin&replicaSet=rs0"

🔧 Troubleshooting

Error: "Cannot connect to MongoDB"

Solution: Make sure Docker is running and containers are up

docker ps
npm run docker:logs

Error: "ReplicaSet not initialized"

Solution: Wait longer (ReplicaSet takes ~10-15 seconds)

docker logs icorm-mongo-rs-init

Error: "Port already in use"

Solution: Stop other MongoDB services or change ports in docker-compose.yml

lsof -i :27017
npm run docker:down

Tests fail intermittently

Solution: May be timing related. Increase timeout or run again

# Clean and restart
npm run docker:down
npm run test:all

✅ Verified Fixes

The tests certify the following fixes applied in mongo.js:

1. ObjectID → ObjectId (Line 11)

global.ObjectID = MongoDB.ObjectId || MongoDB.ObjectID;

✅ Verified in: All tests

2. Race Condition BUCKETNAME Eliminated (Lines 808-877)

// Now created locally in each function
var bucketName = (conn.table !== 'default') ? conn.table : 'db';

✅ Verified in: Concurrency tests

3. reconnectAttempts Thread-Safe (Lines 15-16, 60-107)

const reconnectAttemptsMap = new Map();

✅ Verified in: Connection tests

4. Array Verification in Scalar (Lines 411-444)

var result = (response && response.length > 0 && response[0]) ? response[0].average : null;

✅ Verified in: Group 4 - Scalar Operations

5. Try-Catch in listDatabases (Lines 320-326)

try {
  var result = await client.db(client.$database).admin().listDatabases();
  builder.$callback(null, result);
} catch (err) {
  // Proper handling
}

✅ Verified in: General tests

6. Await insert() in insertexists() (Line 596)

await insert(client, cmd);

  options: opt.options,
  maxPoolSize: opt.maxPoolSize || 10
};

✅ Verified in: Pooling tests

8. Math Operators Fixed (Lines 657-677)

case '-':
  increment[key] = val ? -Math.abs(val) : 0;  // ✅ Negative
case '*':
  multiply[key] = val ? val : 1;  // ✅ $mul
case '/':
  multiply[key] = val ? (1 / val) : 1;  // ✅ Inverse

✅ Verified in: Group 3 - Math Operators

9. Optimized countDocuments (Lines 380-383)

var hasFilter = filter.where && Object.keys(filter.where).length > 0;
var countFunction = hasFilter 
  ? function(callback) { db.countDocuments(filter.where, callback); }
  : function(callback) { db.estimatedDocumentCount(callback); };

✅ Verified in: Group 5 - High Concurrency
