I have setup an SMTP sampler in JMeter that gets the body data from a csv file. It reads the first element and then stops. Any suggestions on what could be wrong?
The CSV file looks like this:
"This is
a multiline
record
"`"This is
a seond
multi line
record
"`"And this is a third record"
Result
Configuration
As per CSV Data Set Config documentation
JMeter supports CSV files with quoted data that includes new-lines.
By default, the file is only opened once, and each thread will use a different line from the file.
So the "line" with newline characters needs to start from the new line (hopefully it makes sense), you need to organize your CSV file a little bit differently to wit:
"This is
a multiline
record
"`
"This is
a seond
multi line
record
"`
"And this is a third record"
If you don't have possibility to amend your CSV file you will have to go for other options of reading the data, i.e. using JSR223 Test Elements and Groovy scripts or storing the data into the database and using JDBC Test Elements for retrieving it

i'm trying to create tab-delimited csv data from json/xml data. While I can do this using payload factory mediator in an iterate loop; the data gets appended to the same line in the file every iteration, creating a long line of data. I want to be append to the next line, but i've been unable to find a way. Any suggestions? Thanks.
(I do not want a solution which uses a csv connector or module)
Edit: I solved it, you just need to use an xslt and "
" line break character.
I'm using v5.1.1 of JMeter and attempting to use the "CSV Data Set Config". The file is read correctly as I can tell from the Debug Sampler/Results Tree, but the file is not being read line by line. In other words, it reads the first line and never proceeds to the next line for processing.
I would like to use the data inside the CSV to iterate over a series of HTTP Requests to an external API. I currently have a single thread with only the "CSV Data Set Config" and "HTTP Request".
Do I need to wrap this with a ForEach controller or another looping construct? Perhaps I'm missing it but I do not see in the documentation that would indicate it's necessary.
Thanks
You dont need to wrap this in a ForEach loop. First line in the CSV file is a var name:
Let's say your csv file looks like
foo, bar
1, John
2, George
3, Laura
And you use an http request sampler
then ${foo} and ${bar} will get iterated sequentially. However please make sure you are mindful about the CSV Data Set Config options. The following options works ok for me:
By default CSV Data Set Config doesn't trigged any "looping", it reads next line from the CSV file for each thread (virtual user) for each iteration.
So if you want to see more values from the CSV file - either add more users or loops or both.
Given
This CSV file:
line1
line2
line3
Following CSV Data Set Config setup:
And the following Thread Group setup:
You will get the following values (assuming __threadNum() function to visualize current virtual user number and ${__jm__Thread Group__idx} pre-defined variable to show current Thread Group iteration) :

I need to create test data preparation script and capture JSON response data to CSV file.
In the actual test, I need to read parameters from CSV file.
Is there any possibilities of saving entire JSON data as filed in CSV file (or) need to extract each filed and save it to CSV file?
The main issue JSON have comma, You can overcome it by saving JSON to file and use different delimiter instead of comma separated, for example #
Then read file using CSV Data Set Config using # Delimiter
Delimiter to be used to split the records in the file. If there are fewer values on the line than there are variables the remaining variables are not updated - so they will retain their previous value (if any).
Also you can save JSON in every row and then get data using different delimiter as #
You can save entire JSON response into a JMeter Variable by adding a Regular Expression Extractor as a child of the HTTP Request sampler which returns JSON and configuring it like:
Name of created variables: anything meaningful, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
Then you need to declare this response as a Sample Variable by adding the next line to user.properties file:
sample_variables=response
And finally you can use Flexible File Writer plugin to store the response variable into a file, if you don't have any other Sample Variables you should use variable#0
I've a csv like this:
NAME;F1;F2;
test1;field1;field2
test2;field1;field2
test3;field1;field2
I would test only test1, so I would change the csv in
ID;F1;F2;
test1;field1;field2
#test2;field1;field2
#test3;field1;field2
how can I skip rows of test2 and test3 in jmeter?
There is always a way to do to something..
maybe my way is not the best and "pretty" but it worth!
Thread Group
Loop Controller
csv Data Set Config
if Controller
Http Request
Inside If Controller I added this code:
${__groovy(vars.get('ID').take(1)!='#')}
In this way when you put an # at the start of the row it will be skipped.
I hope it could be helpfull for someone.
You cannot, the only option I can think of is creating a new CSV file out of the existing one with just first 2 lines like:
Add setUp Thread Group to your Test Plan
Add JSR223 Sampler to the setUp Thread Group
Put the following code into "Script" area
new File('original.csv').readLines().take(2).each {line ->
new File('new.csv') << line << System.getProperty('line.separator')
}
Replace original.csv with path to the current CSV file and set up CSV Data Set Config to use new.csv
The above code will write first 2 lines from the original.csv into the new.csv so you will be able to access limited external data instead of the full CSV file.

I want to implement hadoop mapreduce, and I use the csv file for it's input. So, I want to ask, is there any method that hadoop provide for use to get the value of csv file, or we just do it with Java Split String function?
Thanks all.....
By default Hadoop uses a Text Input reader that feeds the mapper line by line from the input file. The key in the mapper is the number of lines read. Be careful with CSV files though, as single columns/fields can contain a line break. You might want to look for a CSV input reader like this one:
https://github.com/mvallebr/CSVInputFormat/blob/master/src/main/java/org/apache/hadoop/mapreduce/lib/input/CSVNLineInputFormat.java
But, you have to split your line in your code.
