Suppose that I have a request:
http://ip:port/search
with multiple optional query parameters:
key1
key2
key3
I wanna test these parameters one by one, aka each parameter for one request, in ONE sampler instead of multiple samplers.
How could I do it? Thanks.
The most commonly used test element for parameterization is CSV Data Set Config, if you store your query parameters to keys.csv file you can set up your test plan as follows:
and once done you can reference the value as ${key} JMeter Variable where required
This way JMeter will read next value from the file on each iteration of each thread (virtual user) and you will be able to use only one HTTP Request sampler for checking multiple values from the CSV file:

In JMeter I have two Api , one api generate filename and id then these parameters pass to another api here I used plugin path extractor and also use csv data set config to extract , save and pass parameters and its value to another api but problem is when multiple user it generate multiple filename and id but how to pass those file name and id to every httprequest to another api.
You don't need any CSV Data Set Config, it will be sufficient to
Add a suitable Post-Processor to extract the generated file name
The Post-Processor will store the generated name into a JMeter Variable
You should be able to use the variable in the "2nd API"
As per JMeter Documentation Variables are local to a thread so each thread (virtual user) you define in the Thread Group will have its own value.

I am using graphql in jmeter for API testing. Where in graphal we have the query and variable section.
My query would require a client ID which is int. Where as in Variable if I try to pass "{clientid : ${clientid}}"(here I am passing the CSV config variable, for testing the app for multiple users). But it is throwing an error like $ is unauthorised and expecting a (json,null,true or false).
Please help me out how I can pass the clientid which is a csv config variable.
Thanks in advance.
It looks like your CSV Data Set Config setup is not very correct so the JMeter Variable placeholder isn't getting substituted with its respective value from the CSV file.
We cannot help without seeing first couple of lines of the CSV file and your CSV Data Set Config setup so far I can only suggest re-visit the configuration and cross-check it with JMeter Documentation
You can observe JMeter Properties and Variables with their values using Debug Sampler and View Results Tree listener combination, if you don't see clientid line there - the variable is not set and JMeter sends it as it is, to wit "{clientid : ${clientid}}" and doesn't substitute ${clientid} with the value from CSV
My registration form is accepting body in JSON format, and I need to run the test with 5 different user names.
How do I pass JSON as request body? Also I was unable to pass parameter from CSV file. How can I solve this issue?
Add CSV Data Set Config to your Test Plan
Configure it like:
Filename: full path to the file with your emails
Variable Names: anything meaningful, i.e. EmailId
In your HTTP Request sampler copy the recorded value to Body Data" tab and replace hard-coded email with JMeter Variable like:
{"EmailId" : "${EmailId}"}
In Thread Group set "Number of Threads" to 5
Next time you run your test JMeter will read next line from the file.csv and substitute the ${EmailId} variable with the value from the CSV file.
See Using CSV DATA SET CONFIG article for more information on parameterising your JMeter tests via CSV files.
I want to pass test data from one csv file to multiple http requests like first row should take by 1st http sample and second row should take by 2nd http sample.Please help how to use this in jmeter.
You can follow these:
Add your CSV Dataset config in test plan level
Define Thread group (enough thread, ramp-up, duration)
Under thread group, add your requests or samples.
Put your CSV file in the JMeter bin directory.
Use those variables (defined in CSV Dataset) in your requests.
Hint:
CSV Data set Config:
Http Request sampler:
If you need to read a specific (arbitrary) line from a file with each Sampler you can use i.e. __groovy() function for this like:
${__groovy(new File('/path/to/your/file').readLines().get(0),)} - read 1st string
${__groovy(new File('/path/to/your/file').readLines().get(1),)} - read 2nd string
${__groovy(new File('/path/to/your/file').readLines().get(2),)} - read 3rd string
etc.
Demo:
File.readLines() method is a Groovy JDK enhancement to provide some "syntactic sugar" on top of "normal" Java to make developers lives easier.
See Groovy is the New Black article to get started with using Groovy scripting in JMeter tests.
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)
http sample
response assertion
