How to check Multiuser and single user Autologin Load test in my website..
I have studied the tutorial but I don't understand it. Below are the steps that I follow..
Test->Add->Theard Group ->Recording Controller
Test->Add->Config Element->HTTP Request Default
Test->Add->Config Element->HttpCookie Manager
Workbench->Add->NonTestElement->Http(s)Test Script Recorder
I set Httpdomain name->adda52.org, http sampler settings and add exclude patterns in Step 4 and then start. After that I set the browser setting proxy server and run login our site..
Everything is going fine.
Then I add view result and see that the result of each request is fine. Then I pass a dynamic session value by using the following steps:
under Recording controller->login page->add->Post Processer->Regular expression extractor add under reference
name salt (This is my session id)
Regular Expression name="salt" value="(.*?)" />
Match No 1
Default value = session Not found
and then set this session value is my after login page like this : ${salt} and run our script session value is showing on my post data.
My question is
Is my script is correct? if yes then
After login I cannot see on profile page in Response data in View Result trees they are showng blank page ?
How can I make my script to auto login on multiple users and single user?
How can I check load on my site and where
please provide me step and how to check.?
Follow these steps carefully:
List item
test plan->Add->Thread(user)->Thread group
thread group->Add->config element->HTTP Request Defaults
thread group->logic controller->recording controller
Workspace->Add->non-test element->http test script recorder
start your plan & record it.after successful creating of test plan do the following steps: add the csv data set config in your test plan
Thread group->add->config element->csv data set config
in csv data set config file give the parameter values like : in filename:-give your csv file path & in variable name pass the variable as:username,password
in your test plan check the login file in that file change the static values username as "${username}" & password "${password}"
pass the different values in csv file & before start the test plan change the number of thread you want run

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
There is a URL which I want to hit and save the response. The URL id needs to be incremented each time and save the response. For example -
First Get Request - http://google.com/getdata/?Id=1
First Response - one
Second Request - http://google.com/getdata/?Id=2
Second Response - two
and so on...
I want to hit the request with increment the id each time and save the response
I have tried using fiddler but unable to figure how to increment the id and save the response.
P.S. - I have to make around 6,00,000 hits
Since the 'Postman' tag is mentioned, I can help you regarding how to implement this in Postman.
Postman has a nice feature of using 'variables'.
You can use environment variables or globals.
Read more about these on their docs:
https://www.getpostman.com/docs/v6/postman/environments_and_globals/variables
You can use a global variable such as 'counter' and set it to 1 / whatever starting point you want.
Then you can modify your request like so :
http://google.com/getdata/?Id={{iteration}}
Now, in the Tests script of the request you can write the following script
let i = parseInt(pm.globals.get('iteration')) + 1;
pm.globals.set('iteration', i);
Also, to access the response you can use the following command in Test script:
console.log(pm.response); // Use pm.response as per your needs
Save the request in a collection.
Now load the Postman's Runner and select the collection.
Now you can put an iteration count of 6,00,000 and hit run!
Remember, heavy iterations will cause performance degradation.
In JMeter you need to click , Ctrl+0 and Ctrl+1 to create , Thread Group and HTTP Request
In Thread Group put the number of hits you need in Number of Threads (users)
In HTTP Request Put in Server Name or IP www.google.com and in Path /getdata/?Id=${__threadNum}
__threadNum will create increasing number from thread 1 to number of hits.
For small number of hits or debugging you can add View Results Tree to view request/response by clicking Ctrl+9 in Test Plan/Thread Group level.
To save the response use Post Processor, especially by adding Regular Expression Extractor below HTTP Request by clicking Ctrl+2.
Allows the user to extract values from a server response using a Perl-type regular expression. As a post-processor, this element will execute after each Sample request in its scope, applying the regular expression, extracting the requested values, generate the template string, and store the result into the given variable name.
Import to notice that for load testing you need to work with non GUI mode, which means call jmeter using command line as jmeter -n -t myTest.jmx
you will use Command-line mode (called Non-GUI mode) to run it for the Load Test.
Don't run load test using GUI mode !
For saving all responses to a one file see save response data or if you want to save file per thread/user you can add Save Responses to a file
Fiddler:
Open script editor (Control + r ) then add the following code inside OnBeforeResponse
static function OnBeforeResponse(oSession: Session) {
if(oSession.oRequest["X-SAVE-ME"] != "")
{
oSession.SaveResponseBody("C:\\tempfiddler\\" + oSession.SuggestedFilename);
}
}
Go to the "Composer" tab and include the header X-SAVE-ME with any value, in the URL, replace your ID with # (just like this: http://google.com/getdata/?Id=#) fiddler will now ask for the starting and ending value of ID before executing;
Please find the snapshot below for your scenario.
Scenario_Testplan
First, go to user properties and put "sample_variables = ID, Response_File_Name" or whatever the name you choose for the variables. Restart jmeter.
Create the below plan:-
CSV data set config to have incremental values and response file name
HTTP request will use ${ID}
Save response to a file will use ${Response_File_Name}
Hope this will help.
I would do this by command line, using a while loop with a curl to the URL, storing the body result on the standard output to a file. It would look something like this:
for i in {1..600000}; do curl "http://google.com/getdata/?id=$i" > body-result-id-$i; done
I couldn't test the line above because I don't have any access to a console right now, but I think it should work.
In Burp you can do this using the Intruder tool. First, capture a sample request in Burp. If you're unsure how to do this, please consult the getting started documentation.
Then right-click the request and selected "Send to Intruder".
In the Positions tab within Intruder, first click "Clear" then select the section you want to vary, and click "Add"
In the Payloads tab select the Payload type as "Numbers" and configure the range.
Click "Start attack"
For more information, consult the documentation.
One Another solution is that you can use Counter in jmeter. That you can find from below path
Thread Group > configElement > Counter.
Configure the Counter as per your need.
Give the Reference Name i for counter.
Use the variable in your request
For more information.
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.

Login page is having dynamic password field name: every time user visits the login page field name looks like PASSWORD_673834937, and on next visit, it looks like PASSWORD_673857943.
I have created many scripts which were working as of today, but in latest build they bring in this change to the password field... before this it was always PASSWORD only. So all my scripts were failing. What is the workaround, so that all my scripts start working with dynamic field name?
OLD JMETER SCRIPT using name as "PASSWORD"
NEW changes to the password field
Under register.asp sampler, add RegEx Post-Processor
Specify the following parameters:
(i.e. the regular expression is <input TYPE="password" NAME="([^"]+)")
In HTTP Request, in the row where password is provided, specify variable created by RegEx Post-Processor in Field name, instead of static name. For example, since the variable I created above is called PasswordFieldName, the HTTP Sampler should look like this (omitting irrelevant parameters):
This is a matter of missing correlation, you would need this sooner or later given you continue playing with JMeter.
The idea of bypassing dynamic parameters is building your Test Plan as follows:
Request 1 (open login page)
Extract dynamic parameters and store them into JMeter Variables
Request 2 (perform login) providing credentials and all dynamic variables from the previous step
Add CSS/JQuery Extractor (be aware that it is not recommended to use regular expressions to work with HTML data) as a child of the register.asp page and configure it as follows:
Reference Name: anything meaningful, i.e. name
CSS/JQuery Expression: input[title=Password]
Attribute: name
Replace PASSWORD_673834937 with ${name} in the new script.
Is try to use the CSV Data Set Config to insert a different username password for each Thread.
When posting to a login page the value of the password variable isn't resolved. The username variable is no problem. The variable is correctly loaded into the Thread because the Debug Sampler is showing the correct value for the password. I already tried to change the name of the variable, perhaps it clashes with some other variable name, but that didn't work.
Perhaps it's because the password field is a different type of input field?
Please let me know if need to clarify this more.. :)
Screenshot to clarify the situation:
1 - CSV-File
2- CSV Data Set Config
3 - Result Debug Sampler
4 - HTTP Request of the login page
5 - Result of the send request to the login page
Because here the variable isn't translated to the value the login process fails.
In your CSV Data Set Config element, in Variable Names (comma-delimited) field you have usernamecsv, pwdcsv... You need to remove space after comma!
usernamecsv, pwdcsv ---> usernamecsv,pwdcsv
This will solve your problem.
