Configuration Elements - JMeter Test Plan

Configuration elements in JMeter are used to set up default values that can be applied to all Samplers in a specific Thread Group. This provides a way to avoid redundancy and simplifies the creation of a test plan. In this tutorial, we will discuss the basics of Configuration Elements in JMeter and how to use them.

Syntax

Configuration elements are defined by adding them to the Thread Group.

Thread Group
- HTTP Request Defaults
- User Defined Variables
...
- Sampler

Example

A common use case for Configuration Elements is to set up default values for the HTTP Request Sampler. Here is an example of setting the default server for all HTTP Requests:

1. Right-click on the Thread Group and select Add → Config Element → HTTP Request Defaults
2. In the HTTP Request Defaults configuration window, enter the server name in the Server Name or IP field
3. Save your changes

Now, every HTTP Request added to the Thread Group will use this default server name unless overridden.

Output

The output of the example above will result in all HTTP Requests using the default server name unless overridden.

Explanation

Configuration elements are used to simplify the creation of test plans in JMeter. Rather than setting up default values for each Sampler individually, Configuration Elements allow you to set up default values for all Samplers in a Thread Group.

Use

Configuration Elements are typically used to set up default values for Samplers, such as server names, timeouts, and other parameters. This simplifies the creation of tests and reduces redundancy.

Important Points

• Configuration elements in JMeter allow you to set up default values for Samplers in a Thread Group
• They save time and reduce redundancy by avoiding the need to set up default values for each Sampler individually
• Common use cases for Configuration Elements include setting up default server names, timeouts, and other parameters

Summary

In this tutorial, we discussed Configuration Elements in JMeter and how to use them to set up default values for Samplers in a Thread Group. We provided an example of setting up a default server name and explained how Configuration Elements save time and reduce redundancy when creating JMeter test plans.
