When I try to add input param in a non-GUI mode in JMeter, it adding an extra space at the end of the variable. There is no space when I enter the params but it is added to the API value when run.
JMeter doesn't "add" or "remove" anything, if there is a "space" - then it's you who added it.
JMeter GUI doesn't show whitespaces so you can open the test plan with any text/XML editor of your choice (JMeter's JMX scripts are basically XML documents) and see if there is a blank space there.
If the variable comes from an external source (Post-Processor, CSV File or Database) you might want to check it at its source.

I am trying to parameterize my request using CSV Data Set Config. My input includes double quotes("), colon(:) and brackets([])
Eg: fiscal_year ":["2021",2019]"
Had tried with it, but in the actual results its passing as "fiscal_year "":[""2021""
Please share your inputs on what am i missing on the input paramter.
I don't think it's due to double quotes("), colon(:) and brackets([]), CSV stands for comma-separated values so JMeter treats it as a delimiter and reads everything including to the first comma.
So you might want to change the "Delimiter" to something else:
It's hard to come up with a comprehensive solution without seeing at least couple of lines from your CSV file and the way you're parameterizing the HTTP Request with JMeter Variables
In case you have one entry per line in the CSV file it might be easier to go for __StringFromFile() function which reads next line from the file each time it's being called. See Apache JMeter Functions - An Introduction for more information.
http request default. http request config. csv data config used. csv data file used .I wanted to add data from csv file, but if i pass single parameter also its adding "&" character before parameter.
ex: https://www.linkedin.com/start/join?&name=A0A1A0
Just remove this ? sign from the /api/dealer/searchByPostalCode
JMeter automatically detects query string beginning in the URL path and tries to merge parameters with the ones you specify in the path to avoid syntax errors.
Given you don't provide any parameters in the "Path" section you should remove ? from there.
Another possible reason is that your CSV data contains this & character, double check it using Debug Sampler and View Results Tree listener combination.
As per the official documentation:
As a special case, the string "\t" (without quotes) in the delimiter
field is treated as a Tab.
When the end of file (EOF) is reached, and the recycle option is true,
reading starts again with the first line of the file.
Source: http://jmeter.apache.org/usermanual/component_reference.html#CSV_Data_Set_Config
So I'd request you to remove \n in delimiter field from the CSV Data set config and then try.
I need to capture some values from Response data and add them to the same CSV file which is used to generate HTML reports (not to a separate CSV file). The reason I want to do this is to filter the Response times by any value I capture, in this case LOBs or GroupIDs (last 2 columns). In the picture, column A thru P are from JMeter generated results, but I want to add column Q and R also with captured values.
Results
Add a suitable Post-Processor to extract LOBs and GroupIDs, make sure to use exactly the same variable reference name:
Add the next line to user.properties file:
sample_variables=LOBs,GroupIDs
That's it, next time you start JMeter you will see 2 extra columns added to the .jtl results file containing variable values for each Sample Result.
If you don't want to make the change permanent instead of adding the above line to the user.properties file you can pass it via -J command-line argument like:
jmeter -Jsample_variables=LOBs,GroupIDs -n -t test.jmx -l result.jtl

Using JMeter to support functional API testing and have run across a problem with reading data from a CSV file. The data from the file is used in building a POST data body which contains something like this:
"wibbles" : ${wibble-var},
${wibble-var} is read from a CSV file and has the format :
["wibble1","wibble2","wibble3"]
... there are over 1000 wibble values in the list.
If "wibbles" : ["wibble1","wibble2","wibble3"]... is hard-coded into the POST body, then JMeter is happy, builds the POST request and does the business, but it's proved impossible to create a CSV file with even the 3 value example above, that JMeter will parse. JMeter skips the thread containing the 'CSV read' without building the POST request or sending it, so there's no response to examine, and a Debug Sampler is similarly skipped. I've heard rumours that doubling up the quotes can work but haven't been able to find the right syntax. Can anyone throw any light on this issue? Thanks
Double quotes will work if you can get "wibble1,wibble2,wibble3" & if you set Allow quoted data to true in CSV data set config
You can get this value and then use beanshell preprocessor to convert to the format "wibble1","wibble2","wibble3".
If you want to get in this format "wibble1","wibble2","wibble3" directly, you can use \t as the delimiter & modify the data in the CSV file accordingly.
Trial and error led to the following solution.
The format of the single data variable I needed to parse is ["value1","value2","value3"] (i.e a JSON array.) and this is exactly what the CSV file contained (with a header name of course on the first row), including the [ and ] brackets.
I modified the parameterised POST body to:
"wibbles": [${wibble-var}],
-- that is, I moved the square brackets out of the CSV file so that the CSV file now just contained the quoted elements of the array:
"value1","value2","value3" etc
I then set the delimiter in the CSV Data Set Config to |
And Allow Quoted Data to FALSE. <--- This was a bit counter intuitive but without it JMeter would not read the whole comma separated list of 2000 quoted strings as a single variable.
With these changes in place the script executed correctly.
Thanks again for the responses, I will definitely look at the __String functions mentioned.
I would go for the following options:
If your "wibbles" are a single string which you need to pass a a JSON Array it might be a lot easier to access them via __StringFromFile() or __FileToString() functions like:
"wibbles" : ${_StringFromFile(/path/to/file/containing/wibbles,,,)},
If you need to access individual "wibbles" and your CSV file is basically a JSON file:
Add HTTP Request Sampler to your test plan (before one which sends these "wibbles") and configure it as follows:
Protocol: file
Path: c:/testdata/yourfile.csv
Add JSON Path PostProcessor and use a JSON Path query to store the "wibbles" into a JMeter Variable(s)
I have a Jmeter script which will fire some HTTP requests. From the requests i am getting the required values to my output.
In the jmeter.properties file i have mentioned as follow:
# For use with Comma-separated value (CSV) files or other formats
# where the fields' values are separated by specified delimiters
# Default:
#jmeter.save.saveservice.default_delimiter=|
# For TAB, since JMeter 2.3 one can use:
#jmeter.save.save-service.default_delimiter=\t
But it is not reflecting in my output.
How to resolve this issue?
I have the same problem. I've added to the jmeter.properties file the following lines:
jmeter.save.saveservice.output_format=csv
jmeter.save.saveservice.default_delimiter=;
csvread.delimiter=;
Now Simple Data Writer saves results using ; to separate fields' values. But when I save data in the Aggregate Report element (by clicking the 'Save Table Data' button) the values in result aggregate.csv file are separated by ,
If you really did what you are describing in the code excerpt, then you forgot to uncomment fields by removing # before the concerned line.
Furthermore you are making a mistake in the property names, they should be:
jmeter.save.saveservice.default_delimiter=|
jmeter.save.saveservice.default_delimiter=\t
For full reference, see jmeter.properties.
But I am not sure to answer your question , as it is not clear though, can you clarify it.
