I am trying to do some test with jMeter.
I have CSV file with the urls and want to iterate over all of them and make HTTP Request. I have achieved that by typing exact number of urls in the ThreadGroup in Loop Count field.
Is there any possibility to set jMeter in that way it will loop over the urls without the need to type count of the urls in ThreadGroup? Any controller can do this?
You can define the urls in the csv data format and have Jmeter loop through it.
The csv file can be defined and loaded with the CSV data config.
The variable names stand for each of the columns in the csv file, and can be referred in the loop controllers.
Example:
Define an while controller with the Condition as ${url}
Define an child CSV Data Set Config, with the file path and the variable name url which stands for the column listing the urls.
Use the ${url} with the http request handler to fire the request.
To stop execution after the end of the CSV file is reached: within the CSV Data Set Config set Recycle on EOF? = False and Stop thread on EOF? = True.

I have one GET request which returns a token. I need to run this request 50 times and each returned token is appended to a single file or array which I can randomly choose and use tokens for other requests. Is it possible in Jmeter
Add a Post-Processor to extract the token and save it into a JMeter Variable
Declare the variable as a Sample Variable
Save the extracted value into a CSV file using Flexible File Writer
Use Random CSV Data Set Config to read the random token from the CSV file created in the previous step
i am new to jmeter. i would like to run multiple urls at one shot and display the results on one screen. finding hard to config urls through csv file and in jmeter.
my sample url:
http://10.56.34.67:7065/services/sample/2070
http://10.56.34.67:7065/services/sample1/2070
http://10.56.34.67:7065/services/sample2/2070
like this i have more thn 100 url to test it.
could you please tell me the format to store urls in csv file and how to config the csv file in jmeter?
It has simple as
Click Ctrl+0,Ctrl+1 which adds Thread Group and HTTP Request in side
In HTTP Request add ${path} to Path field
In Thread Group choose Loop Count Forever
Add CSV Data Set Config by right click on Thread Group -> Add -> Config Element
CSV Data Set Config parameters :
a. Put the fileanme in Fileanme field
b. Enter in Variable Names path
c. Choose Recycle as False
d. Choose Stop Thread as True
Click Ctrl+R (run)
It will go through all URLs and submit them sequentially
To view results you can add View Results Tree (Click Ctrl+9) and you will see all your requests/responses.
It seems your data here is your URLs.
So instead of using multiple samplers for each URL, you can go for CSV Data config and store all your URLs there and name the column as URL.
you can refer to this in your single http sampler as ${URL}.
Your CSV should look like this
In Server name put ${URL} and in the Thread Group check the forever check box
You don't need CSV for this use case, the easiest way would be going for __StringFromFile() function.
In the HTTP Request sampler put the __StringFromFile() function into "Path" input field like:
The textual function representation is ${__StringFromFile(urls.txt)}, you will need to replace urls.txt with full or relative path to the file where your URLs are listed
That's it, each time the request is called JMeter will read the next line from the file and substitute request path with the string from file:
See Apache JMeter Functions - An Introduction article to get familiarized with JMeter Functions concept
This is my test URL " http://appr.seconddemo.org/hitssurveys/survey?uid=113&offerid=311&subid=subvalues&offr_id={Email} "
I want to hit the url 1500 times per second , and want to change the "{Email}" with real value in each iteration.
How it's possible please give me a step by step guide.
Considering that you need to pass the emails from the external file, the most efficient way that we are using in software testing companies is to pass the variable from .csv or .txt files using 'CSV Data Set Config' element of the JMeter.
Please find the steps that you need to follow:
Add a 'CSV Data Set Config' element from 'Config Element' by right-clicking the thread group
Set Filename field with complete path to your .csv or .txt file that contains your emails
Set Variable field as 'Email' [This variable name should be same as you set in your url request]
Ignore first line to False
Set other fields as per your requirement
Now add HTTP Sampler in your Thread Group and set the Protocol, Server Name, Method & Path as instructed in the screenshot:
Create .csv or .txt file and add all emails separated by new line:
Hope this answer is useful.
You can use the CSV Data Set Config. Put all your email credentials in the CSV file and make sure you have put this CSV file in your JMeter /bin directory.
Add a CSV dataset config in your test plan. Your CSV dataset config should be like:
Now in your thread group, define the number of threads you want to execute and then in your sampler put the path as follows:
http://appr.seconddemo.org/hitssurveys/survey?uid=113&offerid=311&subid=subvalues&offr_id=${Email}
Depending on where do your emails live there are following options:
If they are in a text file, each email on a new line you can use __StringFromFile() function like:
If they are in a database you can use JDBC PreProcessor to fetch the data from the database table column and put your request under ForEach Controller
If you need to provide just some random characters you can use __RandomString() function.

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 ${EmailId} variable with the value from the CSV file.
See Using CSV DATA SET CONFIG article for more information on parameterising your JMeter tests via CSV files.
On my site I have two merchant actions: search and browse. A search normally triggers three browses.
I have a JMeter test which uses a CSV file of merchants and merchant id numbers, when running this test at scale I want all the merchants on my site to be used.
I have mapped this in JMeter like so:
Loop Controller
HTTP Sampler (Search /search/${merchant_name})
CSV data set config (Merchant Name)
Loop Controller
HTTP Sampler (Browse /merchant/${merchant_id})
CSV data set Config (Merchant ID)
I set loop count = 2 in the outer loop and loop count = 3 in the inner loop.
I expect two searches to trigger 6 browse actions. But what I get is a search, followed by three browses, continually until I abort the test.
Have I misunderstood the loop construct? Is this the expected behaviour?
How can I achieve my goal of running a search, followed by three browses, twice?
I think that you're misusing CSV Data Set configuration.
I've got your scenario working as follows:
Given following CSV Files:
merchants.csv containing:
merchant1name
merchant2name
and 2 other CSV files: merchant1name.csv and merchant2name.csv with the contents of:
id1
id2
id3
And following Test Plan Structure:
Thread Group (1 thread, 1 second ramp-up, 1 loop)
Loop Controller (2 loops)
HTTP Request /${merchantname}
Beanshell Post Processor (see below for code and explanation)
CSV Data Set Config (Filename: full path to your merchants.csv file, Variable names: merchantname, all defaults)
Loop Controller (3 loops)
HTTP Request /${merchantid}
CSV Data Set Config (Filename: full path to merchantname1 file, merchantname1 should be property, Variable name: merchantid, all defaults)
By using "all defaults" in regards to CSV Data Set Config I assume the following:
File encoding - blank (my JMeter is running with UTF-8 which is fine for majority of cases)
Delimiter - , (comma)
Allow quoted data - false
Recycle on EOF - true
Stop Thread on EOF - false
Sharing mode - all threads
Beanshell Code:
props.put("merchantname", vars.get("merchantname"));
This is required as CSV Data Config does not allow using variables in file path.
Path in inner loop:
C:\jmeter\${__P(merchantname,)}.csv
You can refer to http://glinius.narod.ru/stackoverflow/nestedloop.zip file. Unpack everything from "nestedloop" folder (1 jmx file and 3 CSV files) to /bin folder of JMeter and run the test. It'll produce 8 requests
