How do you configure random parameters in JMeter?

Random parameters can be set in JMeter by following these steps:

1. Add a “User Variables” configuration component to the test plan.
2. Add the variable name and initial value that needs to be set as a random parameter in the “User Variables” configuration component.
3. variable name

For example, if we need to create a random username and use it in the request.

1. Right-click in the test plan, select “Add” -> “Config Element” -> “User Variables”.
2. In the “User Variables” configuration component, click the “Add” button.
3. Input the value “username” in the field labeled “Variable Name” and enter an initial username in the “Initial Value” field.
4. The user with the username ${username}

In this way, JMeter will use a different random username to send requests each time the test is run.

Note: If you need to generate random numbers, you can use the functions provided by JMeter, such as ${__Random(1,100)} which can generate random numbers between 1 and 100.
