Passing parameters to JMeter - jmeter

I can successfully pass parameters through Jmeter as long as I embed them in the path like so:
But when I try to add them using the GUI, it doesn't work:
I have tried combinations of encode/unecode, as well as adding "?" to the path, but the result is the same - the server replies that the required parameter is missing. Any ideas?

This is a post request so pass this name value into Body data (click on body data tab) in json format
{
"Taskid": "9000"
}
or
{
"Taskid": 9000
}
if the type of 9000 is string then choose 1st option other wise 2nd, better to try with both options to check which one is working
Other approach:
try to change the method to get with same parameters as passed in snapshot2 (attached by you) but it might be possible this request does not supports get method then in that situation you have to post it only by passing in the Path field (as shown by you in snapshot 1) or in body data tab

Dynamic Refid is appended to the URL but i can't find refid in the response

When i perform the action on UI a dynamic refid is appended to the URL using query string parameter. I can't find that refid in the response but its part of the request. In the code i only found the variable.
Here is the URL on UI.
https://XXXXXX.XXXXXXXXXXXX.com/Recruiter/#!/candidate/new/157072048
I captured the Get request for the same action using the developer tool on Chrome and it looks like this.
Request URL: https://XXXXXX.XXXXXXXXXXXX.com/Pages/candidate/new.aspx?refid=157072048&mode=quick
This Get request has 2 query string parameter.
refid: 157072048
mode: quick
Now i need to captured that refid and pass it the step 2 to be able to create that record. I need help to figure this out.
I found comment in the html that may be help full.
// referenceid - only used with the "Web" app, gets mapped to "&refid=123" in the query string, and ends up as Page.ReferenceID in WebForms.
If this is not a part of a response data then it might be the case it's generated on the client by JavaScript code. You need to figure out how the value is being generated and replicate the same code using JSR223 Test Elements and Groovy language.
Another possibility is that the value comes from an Ajax request which JMeter doesn't execute because it cannot execute client-side JavaScript. In this case you need to simulate the same request and extract the value from there.
And last but not the least, the number you're looking for may reside in one of the sub-samples which may appear as the result of Redirection and you're trying to find it in main sampler response:

Automate sending a request and saving the response

There is a URL which I want to hit and save the response. The URL id needs to be incremented each time and save the response. For example -
First Get Request - http://google.com/getdata/?Id=1
First Response - one
Second Request - http://google.com/getdata/?Id=2
Second Response - two
and so on...
I want to hit the request with increment the id each time and save the response
I have tried using fiddler but unable to figure how to increment the id and save the response.
P.S. - I have to make around 6,00,000 hits
Since the 'Postman' tag is mentioned, I can help you regarding how to implement this in Postman.
Postman has a nice feature of using 'variables'.
You can use environment variables or globals.
Read more about these on their docs:
https://www.getpostman.com/docs/v6/postman/environments_and_globals/variables
You can use a global variable such as 'counter' and set it to 1 / whatever starting point you want.
Then you can modify your request like so :
http://google.com/getdata/?Id={{iteration}}
Now, in the Tests script of the request you can write the following script
let i = parseInt(pm.globals.get('iteration')) + 1;
pm.globals.set('iteration', i);
Also, to access the response you can use the following command in Test script:
console.log(pm.response); // Use pm.response as per your needs
Save the request in a collection.
Now load the Postman's Runner and select the collection.
Now you can put an iteration count of 6,00,000 and hit run!
Remember, heavy iterations will cause performance degradation.
In JMeter you need to click , Ctrl+0 and Ctrl+1 to create , Thread Group and HTTP Request
In Thread Group put the number of hits you need in Number of Threads (users)
In HTTP Request Put in Server Name or IP www.google.com and in Path /getdata/?Id=${__threadNum}
__threadNum will create increasing number from thread 1 to number of hits.
For small number of hits or debugging you can add View Results Tree to view request/response by clicking Ctrl+9 in Test Plan/Thread Group level.
To save the response use Post Processor, especially by adding Regular Expression Extractor below HTTP Request by clicking Ctrl+2.
Allows the user to extract values from a server response using a Perl-type regular expression. As a post-processor, this element will execute after each Sample request in its scope, applying the regular expression, extracting the requested values, generate the template string, and store the result into the given variable name.
Import to notice that for load testing you need to work with non GUI mode, which means call jmeter using command line as jmeter -n -t myTest.jmx
you will use Command-line mode (called Non-GUI mode) to run it for the Load Test.
Don't run load test using GUI mode !
For saving all responses to a one file see save response data or if you want to save file per thread/user you can add Save Responses to a file
Fiddler:
Open script editor (Control + r ) then add the following code inside OnBeforeResponse
static function OnBeforeResponse(oSession: Session) {
if(oSession.oRequest["X-SAVE-ME"] != "")
{
oSession.SaveResponseBody("C:\\tempfiddler\\" + oSession.SuggestedFilename);
}
}
Go to the "Composer" tab and include the header X-SAVE-ME with any value, in the URL, replace your ID with # (just like this: http://google.com/getdata/?Id=#) fiddler will now ask for the starting and ending value of ID before executing;
Please find the snapshot below for your scenario.
Scenario_Testplan
First, go to user properties and put "sample_variables = ID, Response_File_Name" or whatever the name you choose for the variables. Restart jmeter.
Create the below plan:-
CSV data set config to have incremental values and response file name
HTTP request will use ${ID}
Save response to a file will use ${Response_File_Name}
Hope this will help.
I would do this by command line, using a while loop with a curl to the URL, storing the body result on the standard output to a file. It would look something like this:
for i in {1..600000}; do curl "http://google.com/getdata/?id=$i" > body-result-id-$i; done
I couldn't test the line above because I don't have any access to a console right now, but I think it should work.
In Burp you can do this using the Intruder tool. First, capture a sample request in Burp. If you're unsure how to do this, please consult the getting started documentation.
Then right-click the request and selected "Send to Intruder".
In the Positions tab within Intruder, first click "Clear" then select the section you want to vary, and click "Add"
In the Payloads tab select the Payload type as "Numbers" and configure the range.
Click "Start attack"
For more information, consult the documentation.
One Another solution is that you can use Counter in jmeter. That you can find from below path
Thread Group > configElement > Counter.
Configure the Counter as per your need.
Give the Reference Name i for counter.
Use the variable in your request

Where to insert parameters in Postman

I'm new to Postman Client and have created a GET Request where URL is as following:
https://www.foo.bar/api/script.php/1/1
The PHP File identifies the two parameters and the response is okay. As you can see, there are two parameters for identifier "1" and type "1" that I set manually above.
Now I wanted to "automatize" it. In Postman Client, there is a button to the right of the URL: "Params". I suppose, that here, I have to insert the two parameter values, but I don't the syntax how to do this for "key", "value".
Is there a guideline or step-by-step documentation how to use Parameters?
either you use that button to create two parameters with their value (let's say param1 and param2) and your url will update as follows:
https://www.foo.bar/api/script.php/get?param1=1&param2=1
or create global variables (click on the eye at the top right corner) and use them in your url as follows:
https://www.foo.bar/api/script.php/{{param1}}/{{param2}}
one of those should work ...

Passing whole body as a variable to a POST request

I'm trying to create a simple stress test using JMeter. I have mostly GET requests and a couple POST requests. My main goal is to make this test as reusable as possible. I want to implement it in a way that the user would have to provide a CSV file with the following headers:
method;path;postBody
The values would look something like:
GET;/path/to/resource;''
POST;/path/to/resource;'{"key":"value","key":"value","key":"value"}'
Now POST (PUT, PATCH etc ..) bodies differ from one request to another. Providing ${postBody} to Body Data tab does not work "${postBody}" as well.
Is there a way to achieve this? Command line solutions are more than welcome as well.
EDIT: To clarify, I'm using the UI interface. When I input ${postBody} in the Body Data tab the UI complains. When switching from the Body Data tab to another one I get the following prompt:
Remove "'" around the request and it should work.
Regarding the warning you get, it is not an error, it is just that in JMeter those 2 tabs are exclusive:
Parameters tabs is for input of parameters in the form as name=value
Body data is for your kind of requirement
So can you test my hypothesis which is to remove the quote around the request in CSV file ?
If it still fails, please show the logs.
You can remain in Body Data tab,
Add after pathPost your optional query parameters for GET request:
${pathPost}?${getPramaters}
Don't worry about the ? it's just seperate path from parameters
Also consider changing variable name to path, more suitable because it can be POST.
In JSON , seperate between values while in CSV default is also ,
I suggest you can your CSV delimiter, In CSV Data Set Config Choose different Delimiter as ; and add your data in CSV accordingly (remove extra ' characters):
POST;/path/to/resource;{"key":"value","key":"value","key":"value"}
Notice: Allow quoted data keep default value False

How can I log the value of a variable sent in an HTTP Request sent from JMeter, if the value was first read in from a csv file

I would like to read the exact value of a variable I use to pass through an HTTP Request. I first read in many values of variables using the CSV Data Set Config. For the username, it is in the form of an email address. So, I have a variable called "email" in the Data Set Config. In the actual HTTP Request, for "name", I call it "username". For the "Value" field for this same "username", I added a time() function to it like this so I would end up creating unique users in my tests:
${email}${__time()
When I view the "Request" in a View Results Tree, I can see my parameter is listed correctly:
username=email1%40email.com1390854377360
I do not care if this is correct in real world terms. I already know that is not a valid email. That is ok for now.
What I want to know is how can I log that email that I just created on the fly? I would like to not have to pull in the whole request every time also and then use some type of Regular Expression extractor. It just seems like there should be an easy way to do this.
I think there are 2 ways,
Beanshell Pre/Post processors : you can write custom code in which you can log all your variables in some custom log file
Simple data writer : you can configure it and check save url,save field names,save response data field checkboxes that will give you complete data but in that later postprocessing on result file is required to get all usernames (email in your case).
first approach is easier and allows you create your own logging format(easy to retrieve and use somewhere else).
second approach is somewhat tedious and requires post processing.
