Start the JMeter client.
Create a thread group.

Right-click Test Plan in the upper left corner of the JMeter client and choose Add > Threads (Users) > Thread Group from the shortcut menu to create a thread group for the JMeter test plan. A thread group is the basic execution unit of a JMeter project.
Figure 1 Creating a thread group
Add a request.

Right-click Thread Group, choose Add > Sampler > HTTP Request, and add an HTTP request to the thread group.
Figure 2 Adding an HTTP request
Configure the HTTP request.
The configuration on the Basic tab page of the HTTP request is as follows:
- Protocol: The value can be HTTP or HTTPS.
- Server Name or IP: Enter a domain name or an IP address.
- Port Number: Enter the service port number. For HTTP, the default port number is 80. For HTTPS, the default port number is 443. You can also manually enter other ports.
- HTTP Request: Specify the method, such as GET, POST, PUT, and DELETE. If you select POST, add body parameters.
- Path: Enter the service request path.
Figure 3 Configurations on the Basic tab

On the Advanced tab page of the HTTP request, set the timeout period in Timeouts.
- Connect: timeout period for connecting the client to the tested service. The default value is 20 seconds. You can set it to 10 seconds.
- Response: response time of the tested service after the connection. By default, there is no limit.
Figure 4 Configurations on the Advanced tab
Configure HTTP headers.

JMeter manages HTTP headers by thread group. Each thread group can be configured with an HTTP header manager. Right-click Thread Group and choose Add > Config Element > HTTP Header Manager to add an HTTP header manager. In the right pane of the HTTP Header Manager, click Add to add an HTTP Header.

(Optional) Import file variables, if any.

CSV files are supported. In a CSV file, variable names are in the first row, and data is in other rows.

The following figure shows the variables in text format.

Figure 8 Variables in text format

Right-click Thread Group and choose Add > Config Element > CSV Data Set Config from the shortcut menu. Click Browse to select the target CSV file, and click Open to add the file.

Figure 9 Adding a variable file

To test the effect of referencing variables, you can introduce variables to the HTTP header. A file in ${variable name} format tells JMeter that the variables are read from external systems.

Figure 10 Introducing variables to the header
Save the test plan file and debug the script.

Click on the top of the page, specify the save path and file name, save the test task as a JMX file, and store the project file (JMX) and variable file (CSV) in the same directory. The name of a JMX file contains only letters, digits, hyphens (-), underscores (_), and periods (.). A JMX file with an invalid name cannot be imported to CodeArts PerfTest.

Click the green triangle button on the top to execute the task. You can view the execution result in View Results Tree, including Request Body, Request Header, Response Body, and Response Header.
