I have a requirement to download zip file from server through JMeter to test the peroformance but for me the downloaded files are shown in x-filler, i need to have the zip file downladed.
Please help me here
Thanks in Advance
Simulating file download event using JMeter is as simple as sending HTTP GET request using HTTP Request sampler.
If you need to save the response somewhere for later reuse or analysis add Save Response to a file listener as a child of the request which performs the download. Check out Performance Testing: Upload and Download Scenarios with Apache JMeter article for comprehensive explanation.
Be aware that storing responses will cause huge disk IO overhead during the load test so I would recommend ticking Save response as MD5 hash box under "Advanced" tab of the HTTP Request sampler and use MD5Hex Assertion to compare the MD5 checksum of the response with some reference value.
To download any file, you need to extract it using Regular Expression Extractor.
Add the Regular Express Extractor to the request where you want to download and configure the fields as shown below. Use (?s)(^.*) as the expression to extract everything.
Add the Save Responses to a File sampler and configure the fields as shown below.
Execute the test plan. In the JMETER_HOME\bin\, you can see the zip file. Extract the zip file and validate.
The easiest way is to use your own code to download the file. The options are BeanShell Postprocessor or JSR223 Postprocesor.
I extracted file name from response header Content-Disposition, save it to varible, and the use variable for filename. Additional variable was defined on Test level, holding folder name where to save files.

How to copy a pdf file content into a variable and then upload it as a multipart/related API request using JMeter??
In order to read the file inline or save it into a JMeter Variable people normally use __FileToString() function however it might not work for PDF files because they're binary so you might want to additionally convert it into Base64, the __base64Encode() can be found in Custom JMeter Functions bundle which in its turn can be installed using JMeter Plugins Manager
In general I would suggest recording your file upload request using JMeter's HTTP(S) Test Script Recorder, just remember to copy the PDF file you will be uploading to "bin" folder of your JMeter installation otherwise JMeter will fail to capture the request properly.
I have two HTTP requests (Export and Import).
The result of the "Export" request is a zip file and i want to use that downloaded file in the body of the "Import" request.
Does anyone have an idea ?
Thanks in advance.
Normally you should be storing the file to your drive via Save Responses to a file listener added as a child of the Export request and then specifying the path to the stored file in the "Files Upload" section of the HTTP Request sampler for the Import request

However if your scenario is different and you need to do this in memory, you can read the zip file contents into a JMeter Variable using Regular Expression Extractor and the following regular expression:
(?s)(^.*)
once done you will be able to use the associated JMeter Variable where required.
I'm not able to save response in PDF file generated from the APIs. I am using Jmeter for load testing and by the help of Jmeter I am calling the APIs.
In a Jmeter script I have 150 APIs. It's hard to go through all APIs to check the output. Is there any way to save the data generated by the APIs?
To save response from API you have to add Save Response to a file listener:
Right click on your API request.
Add -> Listener -> Save Response to a file.
Setup Variable Name containing saved file name.
At this step you may enable "Add Timestamp" setting, then date will be included in file suffix following format yyyyMMdd-HHmm_

I try to save response of a HTTP Request with custom file extension. ContentType is application/octet-stream and saved file ends with _1.octet-stream by default. I use Save Responses to a file listener to save file.
Add Save responses to a file listener as a child of the request which output you would like to save
Configure it like:
Replace myfile.txt with your desired filename/extension
That's it, assuming the above configuration JMeter will store the file under the given name

My scenario is load test a functionality which will generate a text file at last, i need to verify the content of that file.
Please guide me step by step to achieve this functionality in jmeter from very beginning to last.
Given you already have your file downloaded to your local hard drive:
Add HTTP Request Sampler to your Test Plan
Configure it as follows:
Protocol: file
Path: /path/to/your/text/file.txt
Add Response Assertion as a child of the HTTP Request
Configure it to test whether the file contains expected data.
See How to Extract Data From Files With JMeter for detailed instructions.
If the file lives in the web, take the same approach, but use http or https protocols to retrieve the file. To save it locally you can use Save Responses to a File listener
