Backend Test Automation: Testing Microservices, Kafka, and gRPC

Modern backend architectures rely on complex microservices, making manual verification slow and error-prone. To ensure system reliability, you must know how to automate tests for asynchronous workflows, databases, and message queues. This course guides you from backend testing fundamentals to writing clean, deterministic automated tests for HTTP APIs, gRPC services, and Kafka streams. You will understand how to manage test environments and run tests inside modern continuous integration pipelines. What you'll learn: - Understand core backend testing concepts, HTTP protocols, and microservice architecture patterns. - Write automated tests for gRPC services and asynchronous Kafka message queues. - Mock external dependencies and manage test databases like PostgreSQL effectively. - Configure isolated test environments using Docker and containerized workflows. - Integrate backend automated tests into automated CI/CD pipelines. - Apply modern practices for writing stable, deterministic tests that avoid flakiness. You will start with essential terminology, basic network protocols, and foundational database concepts before moving on to hands-on testing scenarios. Through clear written explanations and structured code analysis, you will learn to build robust test suites for real-world backend architectures. This course is designed for beginners to test automation and developers looking to expand their quality assurance skills. No prior backend testing experience is required.
