Learn the fundamentals of K6 performance testing through this beginner tutorial that breaks down a basic K6 script line by line. Discover how to understand each component of a simple K6 script including HTTP requests, sleep functions, and the default export function. Master the concept of virtual users (VUs) and how they simulate browser behavior by opening connections, visiting websites, and repeating actions in loops. Explore command-line execution with parameters for virtual users and test duration using the k6 run command. Understand how K6 operates at the HTTP level rather than browser UI automation, and grasp the continuous looping nature of test functions until the specified duration ends. Avoid common beginner mistakes such as removing sleep functions which creates unrealistic load, misunderstanding script execution frequency, and confusing K6 with browser automation tools. Follow a structured approach to building performance testing skills step by step, treating each concept as a level-up in your K6 learning journey.
