Bit of Background, I am using Jmeter to search for a download url from a rest API with an Oauth authorisation token set from the rest API. Once I have this URL I am doing a HTTP request, GET with redirect automatically, keepAlive and browser-compatible headers all checked.
Hanging of this I have then attached a "Save response to a file" with the file name prefix set to "blob" (this will be a filename set by a parameter later) and Add timestamp to the file name checked.
The url in question points to a zip file that needs OAuth header token (which is set successfully) the whole test plan succeeds.
This is great and you can see looking at the results
You can see that there are 67821343 bytes downloaded by the HTTP Request this is what we are expecting to see as this is the size of the file around 67Mb
This is were it starts to go wrong however as the save file only has 10,240 KB is an OCTET-Stream File and renaming this file to a zip just does not work as it is not a complete zip file.
This is my issue the Save file is not saving all the information and only save 10,240KB, every single time.
What am i doing wrong?
Is there a better way to get this zip file?
Please help it is driving me mad.
As once I have downloaded it I then need to assess the contents of the zip file to prove that the download URL that we are being directed to contains the correct ZIP.
here's the RUB if i do it manually through a browser i get the file downloaded successfully and it is exactly the same size (67821343 Bytes) but it just doesn't save in Jmeter.
Add the following property to user.properties file:
httpsampler.max_bytes_to_store_per_request=73400320
This will allow JMeter to save files up to 70MB
You can also set this property to 0 - in this case JMeter will not truncate data (make sure you amend JVM heap so responses could fit in memory)

I am developing JMeter script for an application in which I need to upload file. Let me mention the steps below:
As the application relies on Windows based authentication so I could not use JMeter for recording the steps. Instead I used Blazemeter Chrome extension.
On using the Blazemeter Chrome extension I observed that the details including the uploaded file were recorded in the Parameters section.
I checked the Use multipart/form-data checkbox and then ran the test. But it failed.
Then I used the network tab of chrome to capture the network traffic. Issue with this is that the details sent including the uploaded file were not even displayed in the Parameters section of network tab.
Then I deleted all details from the Parameters section and then entered details in the File Upload tab (note that multipart/form-data checkbox was selected). I ran the test again but it failed.
Then I downloaded Fiddler everywhere to capture network traffic. In this case the details were recorded in the Body -> Form-Data section. Here the issue is for the keys which correspond to file upload the value has weird values which I am not able to comprehend. Something similar to "%PDF-1.3......" and so on. What is this supposed to contain, the file path ?
Now I want to know where should I have the details in JMeter ? In the Parameters section or Body Data section or the File Upload section ? And should I select the checkbox corresponding to Use multipart/form-data.
Thanks in advance.

You could add HTTP Authorization Manager and supply your credentials, domain and so on there, see Windows Authentication with Apache JMeter for more details.
Make sure to copy the file you're uploading to JMeter's "bin" folder
If you need to pass the file in the body data put relative or full path to the file you're uploading in the "Files Upload" tab and make sure that "Use multipart/form-data" is NOT checked.
I am sending a HTTP request to upload a file. And the request is setup like this:
uploadFile
And, the Directory Listing plugin pointing to a directory with all files and the request picks one file at a time. It works fine when run with one thread but, when i run in multiple threads, i see that already uploaded file is picked again to upload which leads to error.
I have added regular expression extrator to get the filename from the request body like this:
extract-filename-from-requestbody
And then, I am trying to use a post processor beanshell script to either delete the file from the folder or move to a different folder. But, not been successful. Need some help on this.
The first issue is i am not sure if i am extracting the value the right way. The value is to be got from request body and not request header. But, i dont see that option in the extractor.
Second, i am unable to use/retrieve the value from the extractor. Tried vars.get, vars.getObject and simply "${fileName}". Nothing works.
I don't think that deleting the file will help because Directory Listing Config reads the folder at the beginning of the test (see Execution Order chapter) so no matter whether the file is physically present or not JMeter will try to upload it
If you want to get unique files without repetitions just untick "Rewind on end of list" box:
This way each virtual user will read the next value so there will be no duplicates. When the last file will be used - the test will stop.

Also going forward consider using JSR223 Test Elements and Groovy language instead of Beanshell, it's the recommended option since JMeter 3.1
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_
Check JMeter Capturing Full Output to get more information.
I am experienced in HP Loadrunner but new in Jmeter.
I recently recorded a script in Jmeter 3.0 where one of the step is to upload a .pdf file. it is a 2 step process:
Step 1> on the upload window click Browse to locate the pdf file from local drive. Once this is done the server puts the file in a temporary directory in the backend and creates a metadata (dynamic value) for it
FYI: I placed the PDF file in the local folder: "Documents\apache-jmeter-3.0\bin\"
Step 2> Once the local file path has been specified (above step) and the button "Upload File" is clicked the file actually gets uploaded to the server and it gets stored permanently.
At this step I need to provide that dynamic value (metadata) to successfully submit the request.
The problem I am having is Jmeter is not returning the metadata (or dynamic value) on the Step-1 of the upload process-
Screenshot: Request/Response details from Jmeter (Step-1)
I recorded the same steps in Vugen 12.53 and it is returning the dynamic value fine for the Step-1-

Can anyone please help?
Thanks!
I can see LoadRunner and JMeter configuration mismatch when it comes to file upload block, I believe you should amend Files Upload section configuration like:
File Path: full path to your PDF file. If you placed in into JMeter's "bin" folder it may be just PerfTest_file_1.pdf
Parameter Name: this guy is the MOST important and this is where you seem to be having clash. Looking into LoadRunner screenshot you name
"Name=file", "Value=blob\\PerfTest_file_1.pdf", "File=Yes", ENDITEM,
and in JMeter for some reason you set this "Name" bit to "blob". I guess correct setting would be "file":
Other settings seem to be fine.
Going forward in order to avoid such situations you can just record your test scenarios. You need to have files you will be uploading in JMeter's "bin" folder so it could locate it while capturing file upload requests.

Just in case, this is how the request header looks like in JMeter-
Screenshot: JMeter Request Header
SOLUTION:
Simply selecting "Implementation" to either "Java" or "HttpClient3.1" solved the problem.
*Points to be noted:
In the "File Path" field either you need to provide the full path of the file location in local drive ("C:/user/Documents/...PerfTest_file_1.pdf") or place the PDF file in the "bin" folder of the Jmeter application folder and just provide the file name (PerfTest_file_1.pdf) as the path
Parameter value for "File" (in my case "blob") should be same as the "Parameter Name" for the file to be attached*
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
