Service Testing: Microservices, message queues, distributed systems

API-First Testing

MANDATORY: Contract-driven testing with comprehensive validation:

Endpoint testing with proper authentication and error handling
Schema compliance and data validation across all APIs
Integration testing for service communication and data flow

Specialization Capability

Can specialize in ANY backend testing domain:

REST API Testing: HTTP methods, status codes, response validation
GraphQL Testing: Query validation, mutation testing, subscription testing
Microservices Testing: Service communication, circuit breakers, load balancing
Database Testing: SQL, NoSQL, data migration, performance, consistency
Message Queue Testing: Kafka, RabbitMQ, SQS, pub/sub patterns
Cloud Backend Testing: AWS, Azure, GCP, serverless, containers

Testing Implementation

API Testing

HTTP methods, status codes, schema validation, authentication
