I have ${__P(NUM_USERS, 1)}, ${__P(RAMP_TIME, 1)}, ${__P(NUM_ITERATIONS, 1)} values set.
I have this in the script:
Thread Group
HTTP Cache Manager
HTTP Cookie Manager
CSV User Data Set Config
Login Controller
Login Request
API call - Got JSON Response
Beanshell - get some stuff out of response and create a hashmap
Beanshell - Print key and values of HashMap
I am expecting it to run once and exit but it shows the print statement from the beanshell 6 times.
What I am doing wrong?

May i know how to achieve this scenario in JMeter.
Requirement 1 : Request 1 should execute for 15 mins, once 15 mins crossed request 2 should execute and request 1 to be stopped.
Requirement 2 : In request 1, we need to capture all dynamic value and store it some place and same dynamic value we should use it as request body for request 2. We like to run large numbers of users. Not sure, how to store all the response in some files or other alternatives.
Ex : Request 1 - > Trigger -> Store response somewhere(15 min run & 100 iteration) - stopped
Request 2 - > Trigger after 15 min - Execute request with above 100 iteration response)
Either take a look at Runtime Controller, using this guy you can choose how long its child(ren) will be run or just put your requests 1 and 2 into separate Thread Groups
If you want to store full responses into a file take a look at:
Post-Processors to capture the required part of the response into a JMeter Variable
Sample Variables property to tell JMeter to save this variable into .jtl results file
Flexible File Writer if you want to write the values into a separate file
My testplan is as follows:
get token: requests to get access token
Setting a user defined variable to get the tokenGeneratedTime, let's say tokenGeneratedTime to ${__time(,)}
Check if token is expired(if controller) - {__jexl3((${__time(,)} - ${tokenGenerationTime}) > 3599000)}
if true, goes to get token sampler
if false, goes to subsequent requests
Some https requests
So if I run this test plan for the first time(only 1 iteration), request to get token is fired, the condition would be evaluated as false and the subsequent requests are fired. All is well and good. But as you can see, if I run the test plan again immediately(not iterating) for the second time, the get token(authorization) requests are fired again, which is not needed. I need to call the get token requests, only on expiry.
I'm thinking of setting a variable to false, if the token is not expired and putting the get token requests under an if controller. But how do I set a variable in if controller?
If you have any other ways of achieving this, please do suggest.
TIA
Use a flag to check the token expiry. e.g. isTokenExpired
Define the variable in the User Defiled Variables section and set the value to true. This will ensure token request is fired for the first time.
Add an IF Controller to the token request and check the condition ${tokenExpired}. Set the flag to false when a token is created successfully. vars.put("tokenExpired","false")
Add a JSR223 Postprocessor to the top level and check the response code 401 for the token expiry response. If the token is expired, set the flag isTokenExpired to true and redirect the thread to the next iteration immediately ctx.setTestLogicalAction(org.apache.jmeter.threads.JMeterContext.TestLogicalAction.START_NEXT_ITERATION_OF_THREAD .
String responseCode=prev.getResponseCode()
if (responseCode.equals("401")) {
log.info("Token is expired ")
vars.put("tokenExpired","true")
ctx.setTestLogicalAction(org.apache.jmeter.threads.JMeterContext.TestLogicalAction.START_NEXT_ITERATION_OF_THREAD )
}
if I run the test plan again immediately(not iterating)
If you run the test plan 2nd time it means that your tokenGenerationTime variable gets a new value of the current timestamp equal to the start time of 2nd execution.
If you want to be able to run your test plan 2nd time within 1 hour without firing the token generation request you can consider writing the tokenGenerationTime into a file using i.e. __StringToFile() function and read it from the file on 2nd and other test executions using __FileToString() function or if your logic is more complex you can go for __groovy() function and implement whatever you want there

I have been receiving this error message on particular request - "Value cannot be null. Parameter name: source".
My Scenario is that 1 user will be transacting 5 transaction (Search and Remit). I'm targeting to run 650 Users to 3250 Transaction. The problem is that one particular request which is getting details from the DB, some data is passed but mostly are the mentioned error message above.
I Have 2 CSV Config, 1 from Users, the 2nd is for the Data where the second csv is inside the Loop Controller.
Your application tells you that the request is not correct, it expects a value and you're failing to provide the value. Use Debug Sampler and View Results Tree listener combination to validate the values of the JMeter Variables which are being sent for successful and not successful requests, it might be a test data issue, for example an extra comma in the CSV file will make CSV Data Set config "think" that this is the delimiter for the next column.
My test plan is as following
- Test Plan
- Thread Group (No of Threads: 4)
- HTTP Request Defaults
- HTTP Cookie Manager
- CSV Data Set Config(Login Information) [4 user login]
- Simple Controller
- HTTP Request(GET: Open Login Page)
- HTTP Request(POST: Login auth)
- Loop Controller
- CSV Data Set Config(Operation Information) [8 operation data]
- HTTP Request(GET: Open Operation page)
- HTTP Request(POST: Commit Operation)
- HTTP Request(POST: Logout)
In this plan suppose I provide 4 users and 8 operation data.
What it doing is running 8 operation for 4 users each in total of 8x4=32 operations.
How could I make this as following
1st user will do 2 operations
2nd user will do 2 operations
3rd user will do 2 operations
4th user will do 2 operations
I want to provide user session wise different operations that 4 users will do number of transactions but the transactions will not be same.
How can I achieve this?
If I'm getting your test scenario correctly you can just set the "Sharing Mode" of your CSV Data Set Config (Operation Information) to Current Thread Group.
Current thread group - each file is opened once for each thread group in which the element appears
If you want more precise control I believe Switch Controller is what you're looking for, using it you can select which user will go for which execution branch.
See Running JMeter Samplers with Defined Percentage Probability article for more information.
As requested, I am posting my solution. Below is the test plan story.
Test Plan
Thread Group
I used only 1 thread in my thread group and 4 in the loop count as shown below.
Loop Controller
CSV Config for the both the files
Output
I've created a BeanShell Listener element in my test plan which I use to collect SampleResult data for each HttpRequest and send to third party software. Presently there are four HttpRequests in my plan:
Get - Hit Login Page
Post - Submit data to Login Page
Get - Hit page to setup session
Get - Hit 'Home Page'
Steps 2 and 3 are related and ran sequentially so from a reporting perspective are essentially '1 step'. I've created a TransactionController around these two elements but my Listener script only appears to be able to retrieve the result data from the second of these two elements. Essentially I want my script to get the total time taken for these two steps for reporting.
Any thoughts?
I can't reproduce your scenario (using JMeter 2.8). Here is how my test plan looks like:
Thread Group
HTTP Request 1
Transaction Controller
HTTP Request 2
HTTP Request 3
HTTP Request 4
Beanshell Listener
My Beanshell Listener has row
log.info(sampleResult.toString() + " - " + sampleResult.getLatency());.
It logs (with omitted log info):
HTTP Request 1 - 143
HTTP Request 2 - 84
HTTP Request 3 - 83
Transaction Controller - 167
HTTP Request 4 - 93
Looks like it works
