I'm making an HTTP Request where a component of the path is dynamic, resulting in unique Sample Results.
For example:
example.com/UNIQUE_ID
The UNIQUE_ID will change upon every request and create a unique request label like in the picture below:
Is there a way to consolidate them under a single entry?
You can use a JSR223 PostProcessor with following code:
String oldLabel = prev.getSampleLabel();
if(oldLabel.startsWith("example.com/")) {
prev.setSampleLabel("MyUniqueSample");
}
And scope it this way:
Just put your request(s) under a Transaction Controller and tick Generate parent sample box - dynamic names will be stored by the Transaction Controller's name.
If you're using JMeter 5.0 you will also need to add the next line to user.properties file:
jmeter.save.saveservice.subresults=false

I have a SOAP request. I need to use jmeter to test multiple requests for same method, each time passing one missing element.
How can I achieve this ?
I tried writing the tags into csv using CSV data config , but I am unable to enter empty values in the csv, each time for a different tag in each csv row.
Any help would be appreciated. Thank you.
The CSV Data Set Config will read the value from next line only on the next iteration of the thread (virtual user), you cannot read more than one line within the bounds of a single iteration. You might want to take a look at __CSVRead() function where it's you who decides when to proceed to the next line.
If the __CSVRead() function isn't applicable for your use case be aware that you can build a request body, i.e. XML from CSV file using JSR223 PreProcessor and Groovy language.
See Creating XML chapter of Groovy documentation for more details.
In my case i have created one HTTP Request with all the possible parameter as below -
My .csv file is looking as below -
For some test case i need to send details in one or two parameter only, not for all. Now how can i do that in the same HTTP request without creating a new one?
Theoretically you can just send empty parameter values, just make sure that you have a blank value in the CSV file, i.e.:
param1,param2
foo,bar
baz,
,qux
Alternatively if you want to completely remove the parameters with empty values from the request you can add a JSR223 PreProcessor as a child of the HTTP Request sampler and put the following code into "Script" area:
def newData = new org.apache.jmeter.config.Arguments()
0.upto(sampler.getArguments().size() - 1, { idx ->
def arg = sampler.getArguments().getArgument(idx)
if (!arg.getValue().equals('')) {
newData.addArgument(arg)
}
})
sampler.setArguments(newData)
This way JMeter will remove the parameters which don't have their respective values from the request:
In the above example sampler stands for HTTPSamplerProxy, see the JavaDoc for all available functions decriptions

i am new to jmeter. i would like to run multiple urls at one shot and display the results on one screen. finding hard to config urls through csv file and in jmeter.
my sample url:
http://10.56.34.67:7065/services/sample/2070
http://10.56.34.67:7065/services/sample1/2070
http://10.56.34.67:7065/services/sample2/2070
like this i have more thn 100 url to test it.
could you please tell me the format to store urls in csv file and how to config the csv file in jmeter?
It has simple as
Click Ctrl+0,Ctrl+1 which adds Thread Group and HTTP Request in side
In HTTP Request add ${path} to Path field
In Thread Group choose Loop Count Forever
Add CSV Data Set Config by right click on Thread Group -> Add -> Config Element
CSV Data Set Config parameters :
a. Put the fileanme in Fileanme field
b. Enter in Variable Names path
c. Choose Recycle as False
d. Choose Stop Thread as True
Click Ctrl+R (run)
It will go through all URLs and submit them sequentially
To view results you can add View Results Tree (Click Ctrl+9) and you will see all your requests/responses.
It seems your data here is your URLs.
So instead of using multiple samplers for each URL, you can go for CSV Data config and store all your URLs there and name the column as URL.
you can refer to this in your single http sampler as ${URL}.
Your CSV should look like this
In Server name put ${URL} and in the Thread Group check the forever check box
You don't need CSV for this use case, the easiest way would be going for __StringFromFile() function.
In the HTTP Request sampler put the __StringFromFile() function into "Path" input field like:
The textual function representation is ${__StringFromFile(urls.txt)}, you will need to replace urls.txt with full or relative path to the file where your URLs are listed
That's it, each time the request is called JMeter will read the next line from the file and substitute request path with the string from file:

on a JMeter test plan, I have too many HTTP requests. One of these creates a new session every time when clicking the create button.
How do I store that session_id in a CSV file for further operation?
Given you have already extracted this session_id using the relevant JMeter PostProcessor you can save its value into a file using JSR223 PostProcessor and the code like:
new File('/path/to/your/file.csv') << vars.get('session_id') << System.getProperty('line.separator')
Make sure you select groovy in the "Language" dropdown and tick Cache compiled script if available box.
If ${session_id} variable exists - JMeter will store its value(s) in the file provided.
There are a few ways to do it. The most useful is RegExp post processor.
It could be found here as it is shown in the following image.
Place it under Request that returns needed data in response.
The RegExp catches groups and stores them under different variable names, based on Name of Create Variable. The values could be searched in different areas of Response, as it is demonstrated in the image, we can search in headers, redirected pages, main bodies and so on. The Stored variable could be re-used in other HTTP Requests or processors (Post and Pre) through ${VariableName} (e.g. ${JSESSION_ID})
Reference name
RegExp itself
Capturing group
Match number
A default value to set if RegExp didn't work
DEBUG:
If a value is not found, the DEBUG in cooperation with Tree Results Viewer can help. Here they are :
The general script structure might look like :
Add BeanShell PostProcessor. Copy, paste the below code (with your modifications for path and var).
var = vars.get("your_variable_name");
FileWriter fstream = new FileWriter("/your/desired/path/results.csv", true);
BufferedWriter out = new BufferedWriter(fstream);
out.write(var);
out.write(System.getProperty("line.separator"));
out.close();
fstream.close();
I have to give dynamic values to url which takes number of users and their age , which can be selected though web page. but I want to give it in Jmeter using BeanShell PostProcessor.
Help me in this,since I'm new to Jmeter.
This is the path:
/destinations/packages?airports%5B%5D=LGW&units%5B%5D=000577%3ADESTINATION&when=29-05-2016&until=&flexibility=true&flexibleDays=3&noOfAdults=2&noOfSeniors=0&noOfChildren=1&childrenAge=3&duration=7114&first=0&searchType=search&searchRequestType=ins&sp=true&multiSelect=true
from what I've got looks like you can use CSV Data Set Config.
Create .txt file with the data you want to feed your test with;
Place the above .txt file to the folder where your .jmx file lies;
In your Test plan: Under your request sampler - place CSV Data set Config;
Then if you need to use your dynamic values within one threadgroup => refer these data as ${quanity}, ${age} in you url.
If you need to pass these values across the threadgroups => add BeanShell Assertion
Then (in the other Tread group) refer those as ${__property(_quantity)},${__property(_age)}.
Hope, it helps.
First of all you need Beanshell PreProcessor, not Beanshell PostProcessor.
All this parameters are basically name/value pairs which can be defined via HTTPSamplerBase class. HTTPSamplerBase class instance is available to Beanshell PreProcessor as sampler pre-defined variable so if you add the following code into the Beanshell PreProcessor "Script" area
sampler.addEncodedArgument("airports[]","LGW");
sampler.addEncodedArgument("units[]","000577:DESTINATION");
sampler.addEncodedArgument("when","29-05-2016");
sampler.addEncodedArgument("until","");
sampler.addEncodedArgument("flexibility", "true");
sampler.addEncodedArgument("flexibleDays","3");
sampler.addEncodedArgument("noOfAdults","2");
//etc
Your HTTP request will be populated with the values, you set via Beanshell.
JMeter Variables can be accessed via vars shorthand which stands for JMeterVariables class instance.
String airport = vars.get("airport");
sampler.addEncodedArgument("airports[]", airport);
//etc
See How to Use BeanShell: JMeter's Favorite Built-in Component article for comprehensive information on how to use Beanshell Test Elements in Jmeter.
Remember that it is recommended to avoid scripting where possible so if there is another way of implementing your task - go for it.
