We have usecase where we need to call an API that uploads its respective category of unique file.
For every API call we need to use a unique FileName. I mean File once used in an API call should not be used again.
For Example
CarAPI will be called by uploading a file-name from list of files (CarAP_1.xml to CarAP_1000.xml files)
File CarAP_1.xml once used in an API call should not be used again in next call
BikeAPI will be called by uploading a file-name from list of files (BikeAP_1.xml to BikeAP_1000.xml files)
File once used in an API call should not be used again.
Any thoughts or inputs on how we can achieve this using JMeter.
You can put these filenames
either to a CSV file and use HTTP Simple Table Server, its READ endpoint has KEEP=false mode so once the data is used it will be removed from memory hence you can avoid duplicate requests
or to Redis and use Redis Data Set Config which also provides possibility to remove the data from the list once it has been utilized
Both plugins can be installed using JMeter Plugins Manager

I'm the company's file server
Get the file as byte[] through the image path and authentication key.
(This server is not accessible to me.)
What I want to do is, when the user downloads the selected files, I want to compress these files and provide them as a compressed file.
Since the company's file server does not have a download API for multiple files, I think I need to request as many APIs as the number of file lists with a for statement in my service API.
In other words, it seems that we need to take a List<Byte[]> and compress this list.
Is there something wrong with my method?
And can I pass the result as json after compression? (I confirmed that the image file is passed as json.)
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
I have a scenario where one of the test REST API returns a transaction_Id, this transaction Id I need to pass in my next request(API Request), also upload the file as well. This upload file has name format like ${transaction_Id}_1_1_bkg.raw,without correct format backend server may not be able to analyze the data.
Since I have to run a load test, these transaction Ids will generate at run time and the same I have to change the file name and upload it as well.
Did any one had face this challenge before in Jmeter to change the file name at run time and upload it, if yes, what was the solution.
Thanks,
Akshat
You could copy the file to a new one with the desired name using JSR223 PreProcessor like
org.apache.commons.io.FileUtils.copyFile(new File('template_bkg.raw'), new File(vars.get('transaction_Id') + '_1_1_bkg.raw'))
where vars stands for JMeterVariables class instance, see the JavaDoc for more information on all existing functions and Top 8 JMeter Java Classes You Should Be Using with Groovy article to learn more about JMeter API shorthands available for the JSR223 Test Elements.
Once upload is finished you can delete the file using JSR223 PostProcessor
I am sending a HTTP request to upload a file. And the request is setup like this:
uploadFile
And, the Directory Listing plugin pointing to a directory with all files and the request picks one file at a time. It works fine when run with one thread but, when i run in multiple threads, i see that already uploaded file is picked again to upload which leads to error.
I have added regular expression extrator to get the filename from the request body like this:
extract-filename-from-requestbody
And then, I am trying to use a post processor beanshell script to either delete the file from the folder or move to a different folder. But, not been successful. Need some help on this.
The first issue is i am not sure if i am extracting the value the right way. The value is to be got from request body and not request header. But, i dont see that option in the extractor.
Second, i am unable to use/retrieve the value from the extractor. Tried vars.get, vars.getObject and simply "${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
Can I have Paw for mac (http rest client) read Dynamic Values from a csv or json file? I need to run 10000 APIs by using different Dynamic Values in my collections.
You could create a dynamic value extension, and use readFile() to read your json file.
I have created a dynamic value extension for passwords, and other such stuff that I don't want to share, when I share my Paw documents.
Please note that because of sandboxing, your json file must live inside you extension folder.
