I stuck on one point and needed your help as I could not get much help on internet.
1. I am using Blazemeter to record my actions on my application.
2. In my application I have to select some criteria on UI (to download only few records) then it is downloading output report on my local as XLSX format.
Note: With this criteria report shows 10-12 records.
3. Then I am using this recorded action in JMETER to check the performance with single user.
4. This request is executing fine and getting response 200 in result tree.
5. Now I change the input criteria (changing in recorded "http request" parameter in JMeter directly) to get huge records in download file (appr. 6500 records).
6. In this case when I start running (by Click Start button), this request is showing response code "500 - Internal Server Error" in result tree.
Q1: Please tell me how to handle this case when we are downloading huge data in XLSX format on the basis of given criteria on UI?
Q2: Or is there any other way to do this kind of work i.e. instead-of recording actions by Blazemeter then play in JMeter?
Need help...

Hello, thanks for your videos, I have to ask.. do you know any other kind of assertion to verify that the type of the document downloaded was correct for example like .xlsx?

[sangeethaanbu]

Hi Raghav, your video is very useful. I have one doubt in File Download . How can i check download file format(i need to check my file format is pdf or not). could you help me in this

[ralfi]

I have a question. If I download a file (100MByte) 100 times (to test the load), the working-memory of my JMETER PC grows extremely linearly.
Does anybody have a solution ? It looks as if JMETER first packs the file into the RAM and then swaps it out into the file.

Hi, Raghav! Your videos are very good! Congratulations!

Please, could you help me in the situation below?

For instance:

Page 1 (Username and Password) > Page 2 > Page 3 > Page 4 (Select an option and, after that, click the box "Download").

These actions were recorded by Badboy software.

The script was used in JMeter. As "Listener", the option "Save Responses to a file" was chosen. The result was wrong, because a file has a content similar to that of Page 1.

In a manual mode, the file must be a spreadsheet with other information.

[shubhamkumar]

hi sir, in my case file is only downloaded in Text/HTML format not in .pdf format, so how to resolve this problem sir ?

[TheLunarah]

This HTTP download request can be fit in many differrent servers, including FTP ones, right? FPT download request only fits for FPT server.
Is that the difference? Thank you.

Hi Sir, in place of filename prefix, can we include variables ? ${file_save_path} ? i tried but not resolving.
