I've multiple http samples in Test Plan but i want to run only one request for multiple times based on csv data set config and remaining http requests will run once particular sample is complete all the iteration based on csv data set config.
In above image i've 5 http samples and i've csv data set for first request,once first request is run for entire csv data set test data then another samples should run,please provide solution how to perform this type of operation in jmeter.
you can use Loop Control and provide the number of hits you needed.
To go to Loop Control:
Right click on the Thread/ThreadGroup
Click on Add
select the Logic controller
Select the Loop Controller
According to the problem, there is a need to execute a particular request to execute in a loop. The loop could be organized in the following way.
-> Thread Group
-> Loop Controller
-->Particular Request
-> Other Request
The CSV Dataset could be found in Config Element and should contain a path to a particular file with data (e.g. accounts.csv).
Both elements could be located in
Loop controller: Add ->Logic Controller -> Loop Controller
CSV Data Set : Add -> Config Elements -> CSV Data Set Config.
The loop can run for the exact amount of records in a file if
Loop Count is equal to a number of strings in the accounts.csv
Forever, it could be stopped by Test Duration automatically or by Stop button.
The CSV Data Set config should have a path to a file with data.
If a file contains headers, then Variables will be assigned based on column names from first string, otherwise, it is necessary to provide variables names in configuration.
ANSWER: If you use 9 variables and all of them are set as header names in a file, then don't provide them in CSV Data Set Config. They will be created automatically, so you can use all 9 variables through names in your file.
If headers are not provided, set 9 all in a Variable Names field, using comma as separator.
Configure your CSV Data Set Config like:
Reference name: foo
Recycle on EOF: false
Stop thread on EOF: false
Put the CSV Data Set Config under the While Controller and put ${__javaScript("${foo}" != "<EOF>",)} into "Condition" input
Add If Controller under the While Controller and put "${foo}" != "<EOF>" into the "Condition" input
Put your first request as a child of the If Controller
Replace foo with your actual JMeter Variable reference name everywhere in the script.
This way JMeter will loop until there are entries in the CSV file and will proceed with the remaining requests when the end of CSV file will be reached.
See Reading all Values from the CSV and Continue chapter of the Using the While Controller in JMeter article for more detailed information on configuring JMeter for your scenario.
You can verify with only one variable and Rest variable you don't required in If and while controller.

I have the following API URL someexample/Create?Name=${Name} where through POST method in jmeter I send the value of Name from the CSV file.
In the response body the value of Name is [1,2,3,4] instead of User1.
Does anyone have an idea why the correct value defined in the CSV file is not being passed?
Thanks in advance.
It's impossible to tell what's wrong without seeing:
First 2 lines of your CSV file
Your CSV Data Set Config setup
If you have i.e. test.csv file which looks like:
User1
User2
User3
etc.
You can configure CSV Data Set Config as follows:
And refer the variable as ${Name} where required.
On each iteration each thread (virtual user) will pick up the next line from the file and the JMeter Variable placeholder will be substituted with data from the CSV in the runtime.
Also you can observe all JMeter Variables with their respective values using Debug Sampler and View Results Tree listener combination

I have ~10,000 records in a csv file that I need to run through postman and check the output it gives.
I was wondering (because I've been doing this manually) if there's a way to import the csv file into postman, and use the rows like variables and just 'scroll' through each result it gives out.
Cheers,
Daniel
This feature exists in Postman runner.
You have to make sure your CSV column's name(s) match the name(s) of your variable(s) in your collection.
You select your CSV file in the "data" part, just above the "start run", and when you run your collection, it will parse your file and replace the variable(s) with the value in the corresponding column and execute the request.
Then it will loop and get the next value and execute, and so on.
It just depends on the content of your CSV file and how you use it in your Postman request.
You shall have a look at those links :
https://www.getpostman.com/docs/postman/collection_runs/working_with_data_files
http://blog.getpostman.com/2014/10/28/using-csv-and-json-files-in-the-postman-collection-runner/
They will give you complete explanation about how it works.

I have recorded a series of 5 HTTP requests in a thread group (say TG). The response value of a request has to be sent as a parameter in next request, and so on till the last request is made.
To send the parameter in first request, I have created a csv file with unique values (say 1,2,3,4,5).
Now I want this TG to run for all the values read from the csv file (In above case, TG should start running for value 1, then value 2, till 5).
How do I do this?
Given your CSV file looks like:
1
2
3
4
5
In the Thread Group set Loop Count to "Forever"
Add CSV Data Set Config element under the Thread Group and configure it as follows:
Filename: if file is in JMeter's bin folder - file name only. If in the other location - full path to CSV file
Variable Names: anything meaningful, i.e. parameter
Recycle on EOF - false
Stop thread on OEF - true
Sharing mode - according to your scenario
You'll get something like:
See Using CSV DATA SET CONFIG guide for more detailed explanation.
Another option is using __CSVRead() function
This method of creating individual request for each record will not be scalable for multiple records. There is another scalable solution here - Jmeter multiple executions for each record from CSV
I have a complex task that I need to complete. It worked well before since there was only one file but this is now changing. Each file has one long row that is first bulk inserted into a staging table. From here I'm supposed to save the file name into another table and then insert the the broken up parts of the staging table data. This is not the problem. We might have just one file or even multiple files to load at once. What needs to happen is this:
The first SSIS task is a script task that does some checks. The second task prepares the file list.
The staging table is truncated.
The third task is currently a Foreach loop container task that uses the files from the file list and processes it:
File is loaded into table using Bulk Insert task.
The file name needs to be passed as a variable to the next process. This was done with a C# task before but it is now a bit more complex since there could be more than one file and each file name needs to be saved separately.
The last task is a SQL task that executes a stored procedure with the file name as input variable.
My problem is that before it was only one file. This was easy enough. What would the best way be to go about it now?
In Data Flow Task which imports your file create a derrived column. Populate it with system variable value of filename. Load filename into the same table.
Use a Execute SQL task to retrieve distinc list of filenames into a recordset (Object type variable).
Use For Each Loop container to loop through the recordset. Place your code inside the container. Code will recieve filename from the loop as a value of a variable and process the file.
Use Execute SQL task in For Each Loop container to call SP. Pass filename as a parameter like:
Exec sp_MyCode param1, param2, ?
Where ? will pass filename INPUT as a string
EDIT
To make Flat File Connection to pick up the file specified by a variable - use Connection String property of the Flat File Connection
Select FF Connection, right click and select Properties
Click on empty field for Expressions and then click ellipsis that appears. With Expressions you can define every property of the object listed there using variables. Many objects in SSIS can have Expressions specified.
Add an Expression, select Connection String Property and define an expression with absolute path to the file (just to be on a safe side, it can be a UNC path too).
All the above can be accomplished using C# code in the script task itself. You can loop through all the files one by one and for each file :
1. Bulk Copy the data to the staging
2. Insert the filename to the other table
You can modify the logic as per your requirement and desired execution flow.
Add a colunm to your staging table - FileName
Capture the filename in a SSIS Variable (using expressions) then run something like this each loop:
UPDATE StagingTable SET FileName=? WHERE FileName IS NULL
Why are you messing about with C#? From your description it's totally unnecessary.
I will be creating flatfiles and based on the data in the batch, it might be necessary to split the data into an undetermined number of files.
I can make the connection string dynamic with an expression, but that is only evaluated when the package starts. I'd like to change that expression to include a '-a' or '-b' in the filename.
Alternately, if I have to create new connection manager objects at run time on demand, how do I go about that?
First determine your naming scheme for the output files and come up with an expression formula in your head
Put the Data Flow Task in a loop.
Within this Data Flow Task, define the source and destination. Destination being the Flat File Destination. Read the source and add some derived column that sets a value to another variable that you'll later use in the Filename expression.
Connect the Flat File Destination to a Connection Manager. First define some path but then add an Expression to define a Connection String based on your File Name scheme (Path + Filename + extension). Now this Filename is tricky. You'll have to put IIF statements based on the values you've got from Source
1) create grobal variable(a variable is created within the scope of a package) and assign it to the file name property.
2) change the variable during the looping.
EDITED
see for more details...
You can access the data set in a script (in the script component) and write out to a set of files based on your criteria.
