What you'll learn:
- Understand performance testing fundamentals including load testing, stress testing, and scalability testing using Locust.
- Write and execute Locust load testing scripts using Python to simulate real-world user behavior for web applications and REST APIs.
- Perform load, stress, and distributed testing with Locust to simulate thousands of concurrent users and high-traffic scenarios.
- Test web applications and REST APIs effectively by handling authentication, validating responses, and creating realistic user flows.
- Analyze Locust test results and performance metrics such as response time, throughput, error rate, and bottlenecks.
- Design real-world, production-ready load testing strategies that can be applied in projects, interviews, and professional performance testing roles.
Master Performance Testing and API Load Testing with Locust (Beginner to Advanced)
This course provides a complete and structured introduction to performance testing and API load testing using Locust. It starts with foundational concepts and gradually progresses to advanced, real-world load testing scenarios.
The course focuses on understanding performance testing concepts, system behavior under load, and practical implementation using Python and Locust.
Course Overview
This course is designed to build a strong foundation in performance testing concepts along with hands-on automation skills.
Learners will begin with basic principles, understand different types of performance testing, learn Python fundamentals, automate APIs, and design and execute load tests commonly used in real projects.
By the end of the course, learners will be able to approach performance testing problems with clarity and structured thinking.
