I want to extract this data in hex form.
I have tried with Regular Expression Extractor and Save Responses to a file but these two methods extract only the plaintext which is a string of non printable characters.
The context is to simulate a VNC authentication using DES.
Any help ?
Binary data in which form? You can add JSR223 PostProcessor as a child of the request and use the following code:
def data = prev.getResponseData()
As a result you will have a byte array holding the response data.
I have no idea about the format, you can find the specification in the RFC 6143
You might need a 3rd-party library like Vernacular VNC or LGPL VNCj in order to properly parse the response and get "interesting" values from there.
See How to Extract Data From Files With JMeter article to learn more about the concept

I trying to extract data from xml response using RegEx. But problem is different xml response but same tag. How do i extract both of them.
This is first xml
This is second xml
As u see there are same tag named "AcctId" but contain different data.
In the first case the value you're looking for is under CAAcctId tag
In the second case the value you're looking for is under AcctId tag
just amend your regex to check the previous line and it should start working as you expect.
Also given you're getting XML it might make more sense to go for XPath Extractor which allows executing arbitrary XPath queries to fetch data from XML/XHTML responses, it will be more readable, robust and reliable than trying to parse XML with regular expressions which are sensitive to markup change
while executing the API's using jmeter tool in the response i get some value as '1K\/vyEh'.
while storing this value in the variable it is observed that the backslash does not get stored in the variable resulting in saving the value as '1K/vyEh'
I need guidance of how to save the value as is in the variable
There are too many "unknowns" in your question so unfortunately it is not possible to provide a comprehensive answer without seeing:
at least partial (better full) response
and the way you're storing the value into a JMeter Variable
Here is a quick demo that in theory it is possible:
The demo assumes:
Dummy Sampler
JSR223 PostProcessor
Groovy language and regular expressions
Currently I am working on moving some API DDT (data from CSV) tests from RobotFramework to Jmeter and what troubles me is the lack of proper JSONs assertion which is able to ignore some keys during comparison. I am totally new to jmeter so I am not sure if there's no such option available.
I am pretty sure we are using the wrong tool for this job, especially because functional testers would take the job of writing new tests. However, my approach (to make it as easy as possible for functionals) is to create jmeter plugin which takes response and compare it to baseline (excluding ignored keys defined in its GUI). What do you think? Is there any builtin I can use instead? Or do you know anything about some existing plugin?
Thanks in advance
The "proper" assertion is JSON Assertion available since JMeter 4.0
You can use arbitrary JSON Path queries to filter response according to your expected result
Example:
If it is not enough - you can always go for JSR223 Assertion, Groovy language has built-in JSON support so it will be way more flexible than any existing or future plugin.
Please find below the approach that I can think of:-
Take the response/HTML/json source code dump for the base line using "save response to a file".
Take the response dump for the AUT that needs to be compare or simply 2nd run dump.
Use 2 FTP sampler's to make calls for the locally saved response dump's.
Use compare assertion to compare the 2 FTP call response's. In the compare assertion, you can use RegEx String and Substitution to mask the timestamps or userID to something common for both so that it will be ignored in comparison.
Below I have shown just an image for my thought's for help.
You need to take care on how to save and fetch the response's.
Hope this help.
I am testing Tibco Soap requests. From the image shown below, I am able to see that I am sending the correct XML in encoded form:
,
But on the receiving server, when the received data is logged, there seems to be extra XML tags whose source I cannot account for, as seen in this image:
.
Note the duplicate XML, in both encoded and un-encoded formats. What could be the cause of this?
Usually that depends where the text is displayed. string variables containing (serialized) xml data will show xml tags as single chars in the content view (once you click in the field). In source view you will see the xml-encoded version (< instead of <) in order to allow a full source view to contain xml data between xml tags.
They are both the same. Usually BW does not auto-convert strings on plain mappings (except frequent translations or literal CR and LFs).
I am using JMeter for a real estate application when I am selecting a plot it is generating a dynamic value like this 1305003402565. It is incrementing like this 1305003280751 per request to request I need to capture this value and I am not able to find it in the source code.
You may be able to force your application to show the dynamic value in the source code by requesting the page as a GET (instead of POST). Then, using Tree View, copy the source into your favorite regular expression extractor to write your regex to extract the value.
