My question is - if I run a test via Jmeter, for example , if it's a site which enables you to book a flight, and you choose your source and destination when you record it.
Is it possible to pass different values to the destination field? I mean, maybe a txt file with some destinations and pass it to the Jmeter test and then, you will have some tests which each of them is running with a different destination?
If yes, how can I do it?
It's not necessary that it will be a txt file. Just a way to pass different values to one parameter.
Important: I'm using blazemeter plugin for chrome.
Thanks a lot,
appreciated.
You can use CSV Data Set Config. It is very easy to use for parameterizing variables in the test plan.
Check this article on blazemeter to understand the CSV Data Set Config quickly.
Depending on what you're trying to achieve you can go for:
HTML Link Parser. See Poll Example which shows how you can use it for selecting random values from inputs
You can extract all the possible values from the previous response using a Post-Processor, most probably CSS Selector Extractor and configure each thread to use its own (or random) value from the input
And last, but not the least, you can use an external data source like .txt or .csv file and utilize __StringFromFile() function or CSV Data Set Config so each thread (virtual user) would read the next value from file instead of using recorded hard-coded values.

I am working on one of the JMeter script and I have one question regarding an item. If I want add both the parameters into body data(Json format) then how can I do? When I record and play it is working fine but I want to modify the script by passing both parameters in Json format, so that I can pass the values from CSV file
Please see screenshot:
One of the value is Json format and other one is button. I know how to pass the multiple values but here one of the parameter is button.
I have passed both the parameters into body data and tried replaying the script but not able to do it with the button parameter. please help here
Your screenshot is not visible.
JMeter doesn't know anything about HTML buttons, it acts on HTTP protocol level
If you want to have the possibility to parameterize any data which is being sent by JMeter just put this data into the CSV file and replace the recorded hard-coded values with the variables defined in the CSV Data Set Config.
Use Debug Sampler and View Results Tree listener combination to see what are the JMeter Variables values and how does request look like. You will also have the possibility to compare the recorded and parameterized requests.
I have a SOAP request. I need to use jmeter to test multiple requests for same method, each time passing one missing element.
How can I achieve this ?
I tried writing the tags into csv using CSV data config , but I am unable to enter empty values in the csv, each time for a different tag in each csv row.
Any help would be appreciated. Thank you.
The CSV Data Set Config will read the value from next line only on the next iteration of the thread (virtual user), you cannot read more than one line within the bounds of a single iteration. You might want to take a look at __CSVRead() function where it's you who decides when to proceed to the next line.
If the __CSVRead() function isn't applicable for your use case be aware that you can build a request body, i.e. XML from CSV file using JSR223 PreProcessor and Groovy language.
See Creating XML chapter of Groovy documentation for more details.
Very new to JMeter (and a long time Stack Overflow listener but first time caller so take it easy on me) so any help would be appreciated.
I am trying to set up a JMeter test that uses multiple dynamically generated access tokens to run across scenarios. I currently have a set of data using the CSV Data Set Config containing login credentials of a user's email and password for example:
email1#email.com,password1
email2#email.com,password2
Next I send a HTTP POST request to the Login service which generates an accessToken. Then, I am using the JSON Extractor to grab the generated accessToken. After that I am using the BeanShell Assertion to store the accessToken property/variable.
My issue seems to lie here in this last step since it will only store the last generated variable instead of each of the generated accessTokens. I want to be able to store/overwrite the grabbed accessToken for each email password combination. I would like it to modify/populate the CSV file like this:
email1#email.com,password1,accessToken1
email2#email.com,password2,accessToken2
I have also tried using the Pre Processor > User Parameters
Screen shot of User Parameters
I would like to have the "userBearerToken" variable update/overwrite along with the tests, but I cannot find a way to do so or if this can even currently be done.
I'm finding it difficult to word what I am trying to ask, but basically I want to store multiple dynamically generated variables (accessTokens that change and time out) and use them in other tests. I don't care which component can handle this (either the CSV or User Parameter), but I need to be able to store these variables with their corresponding email password credentials.
If you want to store the accessToken value into a JMeter property for using in other Thread Group(s) be aware that properties are global for the whole JVM and remain until JMeter is restarted so if you define a single accessToken property - each JMeter Thread (or iteration) will overwrite the value.
The solution is to use current thread (or iteration) number as prefix or postfix, this can be done using either __${__threadNum} function or relevant JMeter Variable depending on how iteration is defined or both.
Example setup:
In first thread group: ${__setProperty(access_token_${__threadNum},bar,)}
In second thread group: ${__P(access_token_${__threadNum},)}
Demo:
If you want to save the values into a file writing into the current one is not the best idea as you can (and most probably will) get malformed file due to a form of a race condition. So I would recommend using Sample Variables property instead.
If you add the next line to user.properties file:
sample_variables=email,password,accessToken
JMeter will store the variables named ${email}, ${password}, and ${accessToken} along with their values in the .jtl results file which is basically CSV file which can be re-used anywhere else.
However if you have a requirement to store only the credentials and the token you can go for the Flexible File Writer plugin and configure it to save the aforementioned variables values into a separate file, the relevant configuration would be as simple as:
variable#0,variable#1,variable#2
You can install Flexible File Writer plugin using JMeter Plugins Manager
URL format is
www.something.com/something/api/{uuid}?code=gomundw0gjq2kbvc3g63whfr9usap5rurjaq5vui5vm6xbt9hhqa8hbcpto4yatwpn26v42t9
I need to make several calls to this GET Url and check performance of the feature.
uuid here is not just the UUID , but is specific to my application
UUID= accountid+identifierid+uuid, which will look like 1234+1234+123e4567e89b12d3a456426655440000
How should I arrange my Jmeter Test Plan.
My Plan would be:
write UUID generated to a file
Using any preprocessor call the file from file and write program to append to a different value in the csv which is account/identifierid.
Please help on this, can some one explain how I should logically arrange my test plan and code to get data to parameterize my path in HTTP Request sampler.
Thanks in Advance
You need to get accountid+identifierid information stored into CSV file. This is something you need to do on your own.
You can use CSV Data Set Config in order to get the information from that file while your test is running, example configuration would be:
UUID can be generated using __UUID() function
So your HTTP Request sampler configuration would be something like:
I have an API call URL similar to this:
http://domain.com/rest/getValues?apiKey=sdfsdf&customerId=2200×tampBegin=2013-08-15%2018:00:00%20CEST×tampEnd=2013-08-19%2018:00:00%20CEST
I would like to dynamically change the time stamps, as well as the customerId, picked from a given set of timestamps and customerIds. Is this possible to do in Jmeter (preferably through GUI)?
Assuming that you are have inputs coming from external CSV file, you can use CSV data set config as explained here.
Your test plan will look something like
Thread groups
CSV Data Set config (define the file path and the variable names. You will be able to read these variables in request.
HTTP Sampler
http://domain.com/rest/getValues?apiKey=sdfsdf&customerId=${custid}×tampBegin=${begin}×tampEnd=${end}
