How to read random data for each request in JMeter - jmeter

I have 4 input parameters which I need to pass in my http request sampler. Everything is OK but the problem is how to first data i have to pass from the previous thread http response and rest 3 from the csv file. Please help.

It seems that you want to update a specific value of the CSV during execution. It would be wise to say that this can be achieved using if controller and User Parameters element. You can go through the below screenshots to resolve this problem.
CSV Data set config for reading csv values
CSV File
Here, I have added text "REPLACE_WITH_RESPONSE" so that we can match it in IF controller.
IF CONTROLLER
This will check if you want to replace this value or not.
Users Parameters
This element would be used to update the csv value with previous request response. In the below example, Date is the CSV value which is replaced with previous Response.
Hope the above solution will help you in resolving this problem.

In jmeter want to add 2 parameter into body(Json).Record and replay is working,but want to pass 2 parameter in Json,so can pass values from CSV file

I am working on one of the JMeter script and I have one question regarding an item. If I want add both the parameters into body data(Json format) then how can I do? When I record and play it is working fine but I want to modify the script by passing both parameters in Json format, so that I can pass the values from CSV file
Please see screenshot:
One of the value is Json format and other one is button. I know how to pass the multiple values but here one of the parameter is button.
I have passed both the parameters into body data and tried replaying the script but not able to do it with the button parameter. please help here
Your screenshot is not visible.
JMeter doesn't know anything about HTML buttons, it acts on HTTP protocol level
If you want to have the possibility to parameterize any data which is being sent by JMeter just put this data into the CSV file and replace the recorded hard-coded values with the variables defined in the CSV Data Set Config.
Use Debug Sampler and View Results Tree listener combination to see what are the JMeter Variables values and how does request look like. You will also have the possibility to compare the recorded and parameterized requests.

Jmeter - Need to check empty tags in SOAP request

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.

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.

Jmeter Parametrization

I'm very new to Jmeter. I need help with the input data file for jmeter.
Here is my situation.
My test data file structure is like this:
Test Case Name = XXXXXX11
RequestData = AAAAAAAAAA11
Expected Result = BBBBBBBBB11
Test Case Name = XXXXXX22
RequestData = AAAAAAAAAA22
Expected Result = BBBBBBBBB22
and so on ....
Now, I have to send the http request and verify the expected using Jmeter (Maven & Continuous Integration).
How can I parse the given file and verify the expected result?
I have tried the following:
__StringFromFile - but i don't know how to look for the line which has Request data or Expected result;
userParameter - but not sure how to pass values on runtime.
Could any of you please help me?
Do you have single test-case per file (i.e. single appearance of "Test Case Name",...,etc. in file)?
If so then you can possibly try to use custom Variables From CSV File plugin from Jmeter Plugins project.
My suggestion would be to convert your file to csv (with any delimiter you like). The first row becomes your heading, and each additional row becomes your data you want to pass in or validate. For example:
Test Case Name|Request Data|Expected Result
XXXXXX11|AAAAAAAAAA11|BBBBBBBBB11
XXXXXX22|AAAAAAAAAA22|BBBBBBBBB22
You can load this data in to your test plan using the CSV Data Set Config. Once you do, you'll be able to loop through each row of data if you set your Thread Group to Loop Forever. Then all you need to do in the test case is refer to your variables from the csv file like so:
${Test Case Name}.
Thank you so much guys!
I just wrote a bean shell script to parse the CSV file and stored all the request & response in the array and then created a for each loop around my http sampler. That met my requirement.
Thread Group
Beanshell preprocessr (To parse my CSV and to store it in an array)
For each loop (loops thru the array)
