I am building out a test suite in jmeter and want to set the assertions to the initial responses that I get from the api calls. Is there any way to do this besides copy pasta?
For clarity each individual call has its own assertion, which for the moment is the response it is receiving.
I want the assertions to be populated by the responses.
If I understood currectly - you are coming up with some JMeter-Baseline script - you also assume that the response you get now is correct - that is what you expect to get it in future as well , so you want to put the response data in the assertion.
If yes, JMeter will not remember the initial responses. So you need to create your script accordingly.
You can have a beanshell postprocessor to write the the responsedata in a CSV file. Later you modify the script to look for the assertion string from CSV file to compare. This is the statement to get the Response Data.
prev.getResponseDataAsString()
As per How to Use JMeter Assertions in 3 Easy Steps guide, JMeter Assertions have their scope.
If you put an assertion at the same level as all requests it'll apply to all of them. See image below for explanation:
I would use a CSV file with the URL and the assertion string you want to match.

Is there a way to send the XML request dynamically and validate the XML response?
My scenario is:
I will have a CSV dataset config and inside the csv file I will have two column, the first one is for the inputXMLFilePath and the second column is the expectedXMLResposneFilePath.
So I need to have a JSR233 PreProcessor under HTTP request sampler, read the input file path convert it to the post body, and also has another JSR233 sampler for load the expected response from the expectedXMLResponseFilePath and compare it with the previous XML response. I have a snippet for JSON which is working fine. but for XML how can I do it?
You can use __FileToString() function for both use cases:
To send the XML request body, like ${__FileToString(${inputXMLFilePath},,)} (where ${inputXMLFilePath} is the variable from the CSV Data Set Config)
To validate the response using Response Assertion configured like:
Field to Test: Text Response
Pattern Matching Rules: Equals
Patterns to test: ${__FileToString(${expectedXMLResponseFilePath},,)}
You can use JMeter Functions literally at the any place of your Test Plan so their flexibility is higher than for other test elements. Also JMeter Functions are being compiled into native Java code therefore their execution speed will be higher and footprint will be less comparing to Groovy scripting.

I have a looping process that will extract some values from a web service (working) and loop through to pull all the information for each value (working).
I need to capture the whole return into a variable so I can modify it and post it back up later.
Screenshot:
When the "Baseline for ..." get kicks in, I get the proper response
But the "Get response" BeanShell PreProcessor is picking up old responses
Screenshot:
Given where my "Get response" object is, I would assume the:
vars.put("ResponceData", prev.getResponseDataAsString());
...would grab the response from "Baseline for ${ID} of site ${callSite}". Please help!
You are using wrong test element. Beanshell PreProcessor is being executed before request therefore it acts properly and returns response from the previous request instead of current one. You need to change it to the Beanshell PostProcessor and your code will start working as you expect.
It is recommended to avoid scripting where possible, if you need to save response data into a JMeter Variable you can do it using i.e. Regular Expression Extractor. According How to Extract Data From Files With JMeter article the relevant configuration will be something like:
Reference Name: ResponceData
Regular Expression: (?s)(^.*)
Template: $1$
If you face a JMeter limitation which cannot be worked around without using scripting make sure you are using the most performing scripting language, since JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language
How can I format json response in jmeter?
I don't want to tell which part of json answer
should be showed. I want to see my response not as
very long one line but as many lines formatted with new lines and
tabs/spaces.
I saw:
http://eclipsesource.com/blogs/2014/06/12/parsing-json-responses-with-jmeter/
Jmeter extracting fields/parsing JSON response
Thanks in advance!
I believe JSON Formatter PostProcessor is what you're looking for
If it is not suitable for you - take a look at JSR223 PostProcessor, it provides prev pre-defined variable (basically SampleResult instance) which gives read/write access to the parent sampler(s) response data so you will be able to do anything you want with the response using Groovy language
I'm a newbie in using Jmeter and searching for a solution solving the following problem: I have a suite that contains a set of atomic HTTP requests and the goal is to save response bodies into an xml file. Currently, I'm handling that with using "Save Responses to a file listener", but need to be able to save separately error and OK responses in different XML, based on response HTTP code and body string.
to illustrate the case with dummy code
if (HTTP response code == 200 OK && body does not contain "ERROR") then
save response to file (%path%\responsename_OK.xml
else
save response to file (%path%\responsename_ERROR.xml
My bad, Nikolay, I forgot you wanted it in xml format...
Well, the easiest way is to add 2 Simple Data Writers (SDW) to each HTTP Request where 1 SDW logs only errors and the other logs only successes.
The Pro's are
it's easy and once you set it up for 1 HTTP Request, you can simply copy it to every other HTTP Request
Each success or failure with be appended to the corresponding .xml file
You can define as much or as little detail as you want
The Con is you add 2 elements to each Request, thus increasing your test size twice as much as you would with a BeanShell Assertion. (if that's a concern for you.)
If you want a more detailed way, you could try a BeanShell Assertion scripted with XML Parsers and XPath Assertions like outlined here.
Use Response Assertion (in fact you will need 2: one for Response Code and another one for Response Body checking) in order to fail the request basing on these criteria
Use If Controller for setting a condition:
${JMeterThread.last_sample_ok} will be triggered if previous sampler is successful
!${JMeterThread.last_sample_ok} - will fire if previous sampler fails
N.B. you should have any Sampler under the If Controller so it could work.
I would like to profile a REST API using JMeter. I would like to write the test plan such that each user thread performs the following actions:
creates a new resource using HTTP POST
If HTTP 201 Created is received, then extract the new resource URL from the Location header of the HTTP response.
Subsequently update the resource using HTTP PUT
Loop in 3 and measure the response time
It's unclear to me how to use JMeter's conditional logic to break up the tests into these discrete parts. I would appreciate any insight anyone can provide on how to implement this.
You need to use If Controller to express this logic.
You can use Regular Expression Extractor to extract Response code (In field to check, check it and extract response code in a Variable)
Use the previously extracted variable in the If Controller condition
