I have dynamically created parameters using regular expression extractor and beanshell script (given below). I am creating parameters with Name = "pass_" + i.
Now I need to populate the value of these parameter field from a CSV file. I have loaded a CSV file and the login variable contains the value of the first row. The below code populates only the first value in the CSV file. I need the code to iterate through the CSV file and populate the parameter fields with next values present in the first column.
int count = Integer.parseInt(vars.get("pass_matchNr"));
for(int i=1;i<=count;i++) { //regex counts are 1 based
sampler.addArgument(vars.get("pass_" + i),vars.get("login"));}
Try using a CSV data config object. You point to the path of your CSV and can then reference each CSV column in a Jmeter variable with ease. With each iteration, your Jmeter variable will hold the value of the next row in your CSV. From here you can use vars.get("yourVar"); to feed this Jmeter variable into your BeanShell script.
Alternatively, if you need the population from CSV to be done in one pass, an option could be to use the CSV data config object and set up your first column and row to be a concatenation of all the values found in the CSV for example 'ValueA,ValueB,ValueC'. You can then feed this variable into your Jmeter script and parse it in BeanShell by doing a split on (','). That'll leave you with all the values found in your CSV.
If these 2 options are unsuitable, a final option would be to create your own Java custom method which you can then feed into your BeanShell script. For example, you could create a class which reads your CSV file and returns a string in the format you desire. For a detailed step by step guide on setting up custom functions in Jmeter, refer to this article.

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

In JMeter, if there’s any function to pass particular values from the CSV datasheet.
In the CSV datasheet first column gives the mobile number and I call the values using parameterization.
${mobile number}
In my CSV datasheet first column gives the mobile number and I pass the values on my request using the parameterization. if there are any functions available to trim the value.
Ex: in CSV datasheet first column value is +911234567890
When I pass the values in the request without a country code.
${mobile number} == 1234567890
If all your entries in the CSV use India country code of +91 you can use __groovy() function like:
${__groovy(vars.get('your-variable-from-csv').substring(3),)}
Replace the your-variable-from-csv with the real JMeter Variable name from the CSV Data Set Config
I want to read a csv file line by line and store that value in variable so that i can pass that in for each activity in Azure data factory.
So I want to read records line by line and store each record in a variable so that we can pass in for each activity one by one and generate new data based on these records.
How can we achive this ?
You can follow these steps:
Lookup active to get the data of the csv data.
Foreach the csv rows.
In Foreach active, set the row value to the variable.
Build your active after the variable, for example:
If you have any other concerns, please feel free to let me know.
HTH.
I'm using Data Factory v2. I have a copy activity that has an Azure SQL dataset as input and a Azure Storage Blob as output. I want to write each row in my SQL dataset as a separate blob, but I don't see how I can do this.
I see a copyBehavior in the copy activity, but that only works from a file based source.
Another possible setting is the filePattern in my dataset:
Indicate the pattern of data stored in each JSON file. Allowed values
are: setOfObjects and arrayOfObjects.
setOfObjects - Each file contains single object, or line-delimited/concatenated multiple objects. When this option is chosen in an output dataset, copy activity produces a single JSON file with each object per line (line-delimited).
arrayOfObjects - Each file contains an array of objects.
The description talks about "each file" so initially I thought it would be possible, but now I've tested them it seems that setOfObjects creates a line separated file, where each row is written to a new line. The setOfObjects setting creates a file with a json array and adds each line as a new element of the array.
I'm wondering if I'm missing a configuration somewhere, or is it just not possible?
What I did for now is to load the rows in to a SQL table and run a foreach for each record in the table. The I use a Lookup activity to have an array to loop in a Foreach activity. The foreach activity writes each row to a blob store.
For Olga's documentDb question, it would look like this:
In the lookup, you get a list of the documentid's you want to copy:
You use that set in your foreach activity
Then you copy the files using a copy activity within the foreach activity. You query a single document in your source:
And you can use the id to dynamically name your file in the sink. (you'll have to define the param in your dataset too):
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.
