I have a scenario where I have sample request in SOAP UI and I want to run those webservice in JMeter.
The issue I have encountered is as follows:
In SOAP UI, we have property "Strip Whitespaces". When set to true, I get the expected output.
However in JMeter, there is no such property hence my request via JMeter are not successful.
Is there anyway to strip whitespaces from whole request not just from variables in JMeter.
Can BeanShell Preprocessor help me?
The sample request which doesnot work in JMETER is something like this:
<Envelope>
<Header>ABC</Header>
<Body>
<Param1></Param1>
<Param2></Param2>
</Body>
</Envelope>
The sample request which works and give expected output in JMeter is:
<Envelope><Header>ABC</Header><Body><Param1></Param1><Param2></Param2></Body>/Envelope>
Add a Beanshell Pre Processor as a child of the request which data you want to change
Place the following code into "Script" section
String data = sampler.getXmlData();
data = data.replaceAll(" ","");
data = data.replaceAll(System.getProperty("line.separator"),"");
sampler.setXmlData(data);
Add View Results Tree Listener and inspect what's being sent.
See How to use BeanShell: JMeter's favorite built-in component guide for more details on how the power of scripting can be used to enhance your JMeter tests.

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 am trying to let JMeter crowl my website to ensure a realistic stress test. I was able to extract the URLs from the home page and iterate on them. So I have a regular expression feeding a ForEach loop.
Now I am not able to let an HTTP Request take the output of the loop (Defined as a variable with a name) as its path.
Is there a general approach to setting the path of such a request. JMeter is taking something like:
${MyVar}
set in the path of the request as a string and is not replacing it with the actual value.
Given your Regular Expression Extractor and ForEach Controller configurations are correct everything should work fine. If you need any assistance with this provide the following screenshots:
Regular Expression Extractor configuration
Debug PostProcessor or Debug Sampler output in the View Results Tree listener showing several generated JMeter Variables
ForEach Controller configuration
HTTP Request sampler configuration (i.e. where do you put the variable)
Be aware that you can mimic crawling the site more easily using HTML Link Parser the relevant configuration would be as simple as

I am trying to use beanshell post processor so I have started with simple http request where I am hitting the google home page. "${url}"=="https://www.google.co.in". After http request page I am adding the BeanShellPostProcessor where in Script area I am using ctx variable and some other code which is like :
int threadNum = ctx.getThreadNum();
String code = prev.getResponseCode();
String message = prev.getResponseMessage();
log.info(threadNum);
log.info("This line has been written by Beanshell Post Processor");
so I have two concerns -
i.The way I am using beanshell is this right ?
ii.Where is the console for beanshell processor in jmeter?
like sample request result can be viewed in listener. I tried with BeanShellListner, but it doesn't show any data.
Also I have kept the "log viewer" on.
You are using it almost right, the only error is that you cannot write an integer to the log file, you need to cast it to String first like:
log.info(String.valueOf(threadNum));
You won't be able to see the result of pre and post processors anywhere apart from jmeter.log file. In case of PostProcessor you can modify parent sampler response data via prev.setResponseData() method where prev is a shorthand to SampleResult class instance
I would also recommend considering switching to JSR223 Elements and Groovy language as this way you will get better performance, out of box support of XML, JSON, etc., and other Groovy's "syntax sugar". See Groovy Is the New Black article for more detailed explanation.
I saved the whole XML in a DB table and am fetching the XML in JDBC sampler and using it in HTTP sampler. I want to parameterize a value inside a particular tag value inside this fetched xml at runtime. Could someone tell me how to do that. Thanks in advance
In http sampler ==> post body
xmldoc = ${xmlfromdb}
Here am able to fetch the whole XML and I can submit it successfully. How to parameterize a tag value inside this fetched xml at runtime.
You can do it via scripting like:
Add Beanshell PreProcessor as a child of the HTTP Request sampler
Put the following code into the PreProcessor's "Script" area
String body = sampler.getArguments().getArgument(0).getValue();
body = body.replace("Original Tag Value", "New Tag Value");
sampler.getArguments().removeArgument(0);
sampler.addNonEncodedArgument("", body, "");
sampler is a pre-defined variable available for Beanshell (and some other Test Elements) which stands for parent Sampler instance and in case of HTTP Request it's HTTPSamplerProxy. See JavaDoc for more information on available methods and fields and How to Use BeanShell: JMeter's Favorite Built-in Component article for more information on using JMeter and Java API from Beanshell test elements inside JMeter script.
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.
