Writing Basic k6 Scripts

Welcome to writing k6 scripts! k6 uses JavaScript to define your load tests, making it familiar for many developers.

A k6 script describes what your virtual users will do and how the load should be simulated.

• Define user actions like visiting pages or logging in.
• Specify the number of virtual users (VUs) and test duration.
• Validate server responses to ensure correctness.

Every k6 script typically has two main parts:

• The options object: Here you configure test-wide settings like virtual users (VUs) and test duration.
• The default function: This is where your virtual users' actions are defined. It's executed repeatedly by each VU.

Think of the default function as the "main loop" for each virtual user.
