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

Suppose a total of 50 users and one HTTP request/sampler were created so in that case we provide one input file when run Api then all 50 users use the same input files (same input file location )and some requests failed.
We want to make ideas or scripts for users to use different file locations so not chance to fail request or file not found exception.
You can parameterize the file name/location just like any other request parameter, username, etc.
The configuration element which is most frequently user for parameterization is CSV Data Set Config.
However if you don't want to manually manage the file content and protect yourself from "file not founds" it makes sense to consider going for Directory Listing Config plugin which reads the files in the given folder and stores them into a JMeter Variable so each thread/iteration will pick the next file from the pool.
You can install Directory Listing Config plugin using JMeter Plugins Manager
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 have the following request:
this will return the following error:
but, if i remove the second file, leaving only one file, the request performs ok
please advice.
My expectation that this is due to missing Parameter Name value as it correlates with Name is blank error.
Can you try the following:
Copy files you want to upload to the "bin" folder of your JMeter installation
Record your file upload event using HTTP(S) Test Script Recorder
Compare recorded script with the one you are currently have.
Another assumption is that your endpoint doesn't support multiple file uploads so you will have to either to it sequentially or use multiple threads and Synchronizing Timer to do it at the same moment but using different threads (virtual users)
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*
I am testing my share point site by uploading/downloading/deleting files using webtest in Visual Studio Ulitmate.
The upload and download file test cases are working as expected.
But the delete file test cases are not working and getting test case failed error.
Even I tried upload and delete file in same test cases also, but this test case also failed.
Kindly assist how to perform delete file test case in VS Load test.
Regards,
David.
Load testing is all about replaying the same scenario multiple times. Note the difference between file upload, download and delete test cases. You can upload a file and download the same file multiple times. However you cannot just delete the same file multiple times.
The problem with the delete test case is likely caused by your script trying to delete the same file multiple times which is causing a SharePoint error.
If this is the case, to fix your script you need to correlate the identifier of the file you're trying to delete.
Currently the request that triggers file delete transaction, contains a constant identifier of the file that you deleted during recording. You need to replace it with an extractor of the file identifier which you will delete during the test execution. For example, if you record a test scenario where you delete the top file on the webpage list, you need to create an extractor from this webpage's response that retrieves the top file identifier. Then use it in the subsequent request that deletes the file.
It looks like Visual Studio did not auto-correlate this test case, so you have to do it manually.
Keep in mind that the "identifier" here can be more than just a single id. It depends on your SharePoint version and some configuration settings.
If you cannot figure out how to find a file identifier in the response, or how to extract it, here's a hint: our load testing tool StresStimulus auto correlates SharePoint. Download it, record the delete file test case and examine the parameter used in file-delete request and what extractor it uses.
After that recreate them in VS.
