How to invoke a local file in JMeter?

To call local files in JMeter, you can follow these steps:

1. By default, JMeter is only capable of sending HTTP requests. To use local files, you need to add an HTTP request.
2. Select the “Body Data” tab in the HTTP request.
3. Select the “Raw” option in the “Body Data” tab.
4. In the “Raw” option, you can enter the file path of the file you want to send. For example, if you want to send the file “test.txt,” you can enter the absolute path of the file, such as: /path/to/test.txt.
5. In other options of an HTTP request, you can specify the request method, header information, and so on.
6. Running the test plan, JMeter will send HTTP requests and send the file content as the body data of the request to the server.

Please note that JMeter simply sends the contents of a file as the body data of a request to the server and does not parse the file content. If you need to manipulate the file content, you can use the pre-processors or post-processors provided by JMeter to handle the file.
