JMeter Functions and Variables

Welcome! In performance testing, it's rare for all users to do the exact same thing or use the exact same data.

To simulate real-world scenarios, your test scripts need to be flexible and dynamic. This lesson explores how to achieve this using JMeter's built-in functions and user-defined variables.

• They make your test scripts more readable.
• They allow you to reuse values throughout your test plan.
• Changing a value once updates it everywhere it's used.

This is crucial for maintainability and flexibility.
