Thanks for the video. in bank projects they do not allow to put our response in third party or unknown sites . But the second option you mentioned in the jmeter itself (Regular expression) is quite useful.Thanks for sharing your knowledge.
Very informative. Thanks Can you pls let know about the login scenario where session if is passed with multiple users And also to check performance of registration of page later save it and any play video performance.
another good use case for this is extracting a CSRF token from a GET login page response and passing it in the POST request for some web frameworks like Laravel
No problem, you can continue with the JMeter videos. They do not have much scripting and meanwhile plan to learn some languages like java - automationstepbystep.com/online-courses/
Hi Raghav. thanks for the explanation If we get an empty right boundary what is the process for the boundary extractor In my application we have one token in the login page.while searching the same in recording I got the dynamic value in response headers,so I found the left boundary but right boundary is empty. How can I handle this If I give the right boundary as empty then I'm getting a lengthy url token in the request body And got 500 error while executing
Dhaana Handling an empty right boundary in JMeter's Boundary Extractor can be tricky, but there are a few strategies you can try: 1. Use a Regular Expression Extractor: Instead of relying solely on the Boundary Extractor, you can use a Regular Expression Extractor to capture the token. This allows more flexibility in defining the pattern to match your token. ```plaintext Regular Expression: leftBoundary(.*?)rightBoundary ``` If the right boundary is truly empty, you can use a pattern that captures until the end of the line or a specific character that follows the token. 2. Adjust the Left Boundary: Sometimes, tweaking the left boundary to be more specific can help in capturing the correct token without needing a right boundary. Ensure that the left boundary is unique enough to avoid capturing unwanted data. 3. Use a Post-Processor Script: If the above methods don't work, you can use a JSR223 Post-Processor with Groovy to manually extract the token from the response headers. ```groovy def responseHeaders = prev.getResponseHeaders() def matcher = (responseHeaders =~ /leftBoundary(.*?) /) if (matcher.find()) { vars.put("token", matcher.group(1)) } ``` 4. Boundary Extractor with Partial Right Boundary: If there's any consistent character or pattern that follows the token, even if it's not a full boundary, you can use that as the right boundary. ```plaintext Left Boundary: leftBoundary Right Boundary: (or any other consistent character/pattern) ``` These approaches should help you capture the token correctly without causing errors --
Raghav please do it for some complex application. Not clearly shown the dynamic values getting from the server..when you hover to any step please explain it also what its function and role.your explanation is too simple and clear which is highly appreciated but not satisfactory on single run. Hope you will never disappoint learners like me. :)
Hi Raghav, Veru good session on correlation. If am using a login to a website and then going through subsequent pages. How will I know what cookies/headers/sessionid I need to pass from first HTTP request. I am doing such scenario and having hard time to understand this.
Hi Bhawna, In JMeter, you can capture and use the cookies, headers, and session IDs from the first HTTP request in subsequent requests by using the "HTTP Cookie Manager" and "HTTP Header Manager" elements. Here's how you can do it: Add an "HTTP Cookie Manager" element to your test plan. This will ensure that cookies are stored and sent with subsequent requests. Add an "HTTP Header Manager" element to your test plan. This will allow you to add custom headers to your requests. Send a request to the login page of the website and enter valid login credentials. Check the response headers of the login request for any cookies or session IDs that are returned. You can use the "View Results Tree" listener to view the response headers. Copy the cookie or session ID value and add it to the "HTTP Cookie Manager" element using the "Name" and "Value" fields. If there are any custom headers required for subsequent requests, add them to the "HTTP Header Manager" element using the "Name" and "Value" fields. For subsequent requests, JMeter will automatically include the cookies and headers that you specified in the "HTTP Cookie Manager" and "HTTP Header Manager" elements. By following these steps, you should be able to successfully capture and use the necessary cookies, headers, and session IDs for your JMeter test scenario

Hi Madhu, This is actually your scenario need. Correlation helps to fetch the value based on the regular expression you give. So if you need to fetch any value from the response, you can generate a regular expression to match and use correlation.

Hi Amar, to the best of my knowledge (hoping I can recall), you can put the variable and value at one place like user defined variables, However you will still need to update the variable reference in each of the request for once, Now as its being referred from a single location, in future if any changes happen, you will need to change at one place,

Hi Raghav, I have to do the following in jmeter: store the response(2 values) of the request 1 and add it as input for the second request(second request has parameter body). I tried using json and regex which is not working. Can you please suggest me which one I have to follow?
Hi Vivek Before the details, some videos to help you JMeter Correlation - ruclips.net/video/7-NcyZuUQnw/видео.html JMeter JSON Extractor - ruclips.net/video/3w0x6u4-6ng/видео.html There are a few ways to store the response of the first request in JMeter and use it as input for the second request. One way is to use the *Regular Expression Extractor* post-processor. The Regular Expression Extractor post-processor can be used to extract specific values from the response of a request. The extracted values can then be stored in variables, which can be used in subsequent requests. Another way to store the response of the first request is to use the **BeanShell Post-Processor**. The BeanShell Post-Processor can be used to execute arbitrary Java code. This code can be used to store the response of the first request in variables, which can then be used in subsequent requests. Here is an example of how to use the **Regular Expression Extractor** post-processor to store the response of the first request in JMeter: 1. Add a **Regular Expression Extractor** post-processor to the first request. 2. In the **Regular Expression** field, enter the regular expression that you want to use to extract the values from the response. 3. In the **Variable Names** field, enter the names of the variables that you want to store the extracted values in. Here is an example of how to use the **BeanShell Post-Processor** to store the response of the first request in JMeter: 1. Add a **BeanShell Post-Processor** post-processor to the first request. 2. In the **Script** field, enter the following Java code: ``` vars.put("key1", response.get("key1")); vars.put("key2", response.get("key2")); ``` This code will store the values of the `key1` and `key2` keys in the `vars` object. The `vars` object is a global object that can be used to store variables in JMeter. Once the response of the first request has been stored in variables, you can use these variables in the second request. For example, you could use the variables to create the body of the second request
Hi Raghav, a small question : If on a page we have to select some records and then on the other page (pagenation is there), so how to implement pagenation in jmeter. Can you please explain it through video or any possible way?
Hi Raghav, what if we need to extract more than one different variables from xml response? like customerID, customerName, customerMob... How can we extract all diff variables these and store in single reg expression.
Hi Saurabh, In JMeter, you can use regular expressions to extract multiple variables from an XML response and store them in a single variable using the following steps: Create a regular expression extractor: Right-click on the HTTP sampler that received the XML response, and choose "Add > Post Processors > Regular Expression Extractor". In the regular expression extractor, set the following properties: "Reference Name": This is the name of the variable in which the extracted values will be stored. You can choose any name you like, such as "customer". "Regular Expression": This is the regular expression pattern that matches the values you want to extract. For example, to extract the customer ID, name, and mobile number, you could use the following pattern: "Template": This is the template for the variable that will be created for each match of the regular expression. You can use $1$ for the first match, $2$ for the second match, and so on. For example, to create a variable called "customerID" that contains the value of the first group in the regular expression, you could use $1$ as the template. Run your test and check the results: The extracted variables will be stored in the variable you specified in the "Reference Name" field, separated by the delimiter you specified (by default, a comma). To use the extracted values in subsequent requests, you can reference the variable using the ${} syntax, such as ${customer} or ${customerID}.
@@RaghavPal sure, have put each variable in different reg expression extractor. Trying to put all variables into one extractor. Will use above logic. Thank you so Raghav ... Always helpful 👍✌

how to add list of orders from response headers to next http request example orders:33,45,46 using regular expression extractor add every order in next request but it take only one order id 33
Hi Srinivas, To extract multiple order IDs from the response headers and use them in the next HTTP request, you can use the JMeter Regular Expression Extractor and a Loop Controller. Here are the steps: Add a Regular Expression Extractor as a child of the HTTP request that returns the response headers containing the order IDs. In the Regular Expression Extractor, configure the following settings: "Apply to" should be set to "Response Headers". "Response Headers" should be set to the name of the header containing the order IDs (e.g. "Orders"). "Regular Expression" should be set to a regular expression that matches a single order ID (e.g. (\d+)). "Template" should be set to $1$. Add a Loop Controller as a child of the HTTP request that will use the extracted order IDs. In the Loop Controller, configure the following settings: "Loop Count" should be set to the number of order IDs that were extracted. "Use Separate Thread Group" should be unchecked. Add an HTTP request as a child of the Loop Controller. In the HTTP request, set the path or parameter that contains the order ID to ${order}. Run the test plan. By following these steps, JMeter will extract all order IDs from the response headers and use them in separate HTTP requests inside the Loop Controller. The ${order} variable will be replaced with the extracted order ID during each iteration of the loop

Hi Guhan, the match no signifies that if your regular expression matches multiple values, then which one to consider. For example your regex gives 5 matches and you want to extract the 4th value, you will give 4 in Match No. Now in case you want to match any random value out of extracted values, you can give 0.

Hi Amulya, A 403 Forbidden error with a message about CSRF usually means that the application is using CSRF protection, and JMeter is not sending the correct CSRF token with the request. To fix this issue, you will need to correlate the CSRF token in JMeter and send it with the request. Here's how you can do it: First, check the response of the login request in your JMeter script to see if the server is sending a CSRF token. Look for a response header or body that contains the CSRF token. If the CSRF token is present in the response, you will need to extract it from the response using a JMeter extractor. To do this, add a Regular Expression Extractor post-processor to the login request in your JMeter script. In the Regular Expression Extractor, set the "Reference Name" field to a variable name that you can use later in your script to refer to the extracted CSRF token. Set the "Regular Expression" field to a regular expression that matches the CSRF token in the response. Add a new HTTP Request sampler for the request that is giving you the 403 Forbidden error. In the HTTP Request sampler, set the path and other parameters as necessary. In the HTTP Request sampler, add a HTTP Header Manager to set the CSRF token in the request. In the HTTP Header Manager, add a new header with the name "X-CSRF-Token" (or whatever header the server is expecting) and set the value to the variable name you used in step 3. Save and run your JMeter script again. The CSRF token should now be sent with the request, and you should no longer receive a 403 Forbidden error. It's important to note that the exact steps for correlating the CSRF token may vary depending on the specific application and how it handles CSRF protection. You may need to consult the application's documentation or contact the developers for assistance in correlating the CSRF token.
Hi Raghav, There is one request which takes dynamic parameters I.e no of parameters for the request depends on response from previous request which we extract from regular expression extractor. How to implement this? It would be great help .. Thanks, Harish

Hi Saurabh To extract a value from the request body and export it to a file in JMeter, you can use a combination of a Regular Expression Extractor and a Save Responses to a file listener. Here are the steps: Add a Regular Expression Extractor as a child of the sampler that sends the request. Set the following properties: Name: give a name to the extractor, for example "Extract Value" Apply to: select "Main sample and sub-samples" Field to check: select "Body" Regular Expression: enter a regular expression that matches the value you want to extract. For example, if the value is in a JSON format like {"id":12345}, you can use the regular expression: "id":(\d+) Template: enter $1$ Match No.: 1 Default Value: leave it empty Add a Save Responses to a file listener to the thread group or the sampler. Set the following properties: Filename: enter the filename where you want to save the extracted value. You can use JMeter variables in the filename, for example ${__time(yyyyMMdd-HHmmss)}.txt to include the current date and time in the filename. Variable Name: enter a variable name for the extracted value, for example "myValue" Append: select "false" In the regular expression extractor, add the variable name from step 2 to the "Reference Name" field. For example, "myValue". Save the JMeter script and run it. The extracted value will be saved in the specified file with the given filename. Note: If the request body is not in a JSON format or the value you want to extract has a different format, you need to adjust the regular expression accordingly.

If we get an empty right boundary what is the process for the boundary extractor
In my application we have one token in the login page.while searching the same in recording I got the dynamic value in response headers,so I found the left boundary but right boundary is empty. How can I handle this
If I give the right boundary as empty then I'm getting a lengthy url token in the request body
And got 500 error while executing
Dhaana
Handling an empty right boundary in JMeter's Boundary Extractor can be tricky, but there are a few strategies you can try:
1. Use a Regular Expression Extractor: Instead of relying solely on the Boundary Extractor, you can use a Regular Expression Extractor to capture the token. This allows more flexibility in defining the pattern to match your token.
```plaintext
Regular Expression: leftBoundary(.*?)rightBoundary
```
If the right boundary is truly empty, you can use a pattern that captures until the end of the line or a specific character that follows the token.
2. Adjust the Left Boundary: Sometimes, tweaking the left boundary to be more specific can help in capturing the correct token without needing a right boundary. Ensure that the left boundary is unique enough to avoid capturing unwanted data.
3. Use a Post-Processor Script: If the above methods don't work, you can use a JSR223 Post-Processor with Groovy to manually extract the token from the response headers.
```groovy
def responseHeaders = prev.getResponseHeaders()
def matcher = (responseHeaders =~ /leftBoundary(.*?)
/)
if (matcher.find()) {
vars.put("token", matcher.group(1))
}
```
4. Boundary Extractor with Partial Right Boundary: If there's any consistent character or pattern that follows the token, even if it's not a full boundary, you can use that as the right boundary.
```plaintext
Left Boundary: leftBoundary
Right Boundary:
(or any other consistent character/pattern)
```
These approaches should help you capture the token correctly without causing errors

Yes, you can, JSON extractor is created for JSON response in specific. Reg exp extractor is general
@@RaghavPal Thank you so much Sir

Hi Raghav, Veru good session on correlation. If am using a login to a website and then going through subsequent pages. How will I know what cookies/headers/sessionid I need to pass from first HTTP request. I am doing such scenario and having hard time to understand this.
Hi Bhawna,
In JMeter, you can capture and use the cookies, headers, and session IDs from the first HTTP request in subsequent requests by using the "HTTP Cookie Manager" and "HTTP Header Manager" elements.
Here's how you can do it:
Add an "HTTP Cookie Manager" element to your test plan. This will ensure that cookies are stored and sent with subsequent requests.
Add an "HTTP Header Manager" element to your test plan. This will allow you to add custom headers to your requests.
Send a request to the login page of the website and enter valid login credentials.
Check the response headers of the login request for any cookies or session IDs that are returned. You can use the "View Results Tree" listener to view the response headers.
Copy the cookie or session ID value and add it to the "HTTP Cookie Manager" element using the "Name" and "Value" fields.
If there are any custom headers required for subsequent requests, add them to the "HTTP Header Manager" element using the "Name" and "Value" fields.
For subsequent requests, JMeter will automatically include the cookies and headers that you specified in the "HTTP Cookie Manager" and "HTTP Header Manager" elements.
By following these steps, you should be able to successfully capture and use the necessary cookies, headers, and session IDs for your JMeter test scenario

Hi Amar, to the best of my knowledge (hoping I can recall), you can put the variable and value at one place like user defined variables, However you will still need to update the variable reference in each of the request for once, Now as its being referred from a single location, in future if any changes happen, you will need to change at one place,

There are a few ways to store the response of the first request in JMeter and use it as input for the second request. One way is to use the *Regular Expression Extractor* post-processor. The Regular Expression Extractor post-processor can be used to extract specific values from the response of a request. The extracted values can then be stored in variables, which can be used in subsequent requests.
Another way to store the response of the first request is to use the **BeanShell Post-Processor**. The BeanShell Post-Processor can be used to execute arbitrary Java code. This code can be used to store the response of the first request in variables, which can then be used in subsequent requests.
Here is an example of how to use the **Regular Expression Extractor** post-processor to store the response of the first request in JMeter:
1. Add a **Regular Expression Extractor** post-processor to the first request.
2. In the **Regular Expression** field, enter the regular expression that you want to use to extract the values from the response.
3. In the **Variable Names** field, enter the names of the variables that you want to store the extracted values in.
Here is an example of how to use the **BeanShell Post-Processor** to store the response of the first request in JMeter:
1. Add a **BeanShell Post-Processor** post-processor to the first request.
2. In the **Script** field, enter the following Java code:
```
vars.put("key1", response.get("key1"));
vars.put("key2", response.get("key2"));
```
This code will store the values of the `key1` and `key2` keys in the `vars` object. The `vars` object is a global object that can be used to store variables in JMeter.
Once the response of the first request has been stored in variables, you can use these variables in the second request. For example, you could use the variables to create the body of the second request

Hi Raghav, what if we need to extract more than one different variables from xml response? like customerID, customerName, customerMob... How can we extract all diff variables these and store in single reg expression.
Hi Saurabh,
In JMeter, you can use regular expressions to extract multiple variables from an XML response and store them in a single variable using the following steps:
Create a regular expression extractor: Right-click on the HTTP sampler that received the XML response, and choose "Add > Post Processors > Regular Expression Extractor".
In the regular expression extractor, set the following properties:
"Reference Name": This is the name of the variable in which the extracted values will be stored. You can choose any name you like, such as "customer".
"Regular Expression": This is the regular expression pattern that matches the values you want to extract. For example, to extract the customer ID, name, and mobile number, you could use the following pattern:
"Template": This is the template for the variable that will be created for each match of the regular expression. You can use $1$ for the first match, $2$ for the second match, and so on. For example, to create a variable called "customerID" that contains the value of the first group in the regular expression, you could use $1$ as the template.
Run your test and check the results: The extracted variables will be stored in the variable you specified in the "Reference Name" field, separated by the delimiter you specified (by default, a comma). To use the extracted values in subsequent requests, you can reference the variable using the ${} syntax, such as ${customer} or ${customerID}.
@@RaghavPal sure, have put each variable in different reg expression extractor. Trying to put all variables into one extractor. Will use above logic. Thank you so Raghav ... Always helpful 👍✌
@@RaghavPal Hi Raghav, I have given the below parameters and still not working.

how to add list of orders from response headers to next http request example orders:33,45,46
using regular expression extractor add every order in next request but it take only one order id 33
Hi Srinivas,
To extract multiple order IDs from the response headers and use them in the next HTTP request, you can use the JMeter Regular Expression Extractor and a Loop Controller. Here are the steps:
Add a Regular Expression Extractor as a child of the HTTP request that returns the response headers containing the order IDs.
In the Regular Expression Extractor, configure the following settings:
"Apply to" should be set to "Response Headers".
"Response Headers" should be set to the name of the header containing the order IDs (e.g. "Orders").
"Regular Expression" should be set to a regular expression that matches a single order ID (e.g. (\d+)).
"Template" should be set to $1$.
Add a Loop Controller as a child of the HTTP request that will use the extracted order IDs.
In the Loop Controller, configure the following settings:
"Loop Count" should be set to the number of order IDs that were extracted.
"Use Separate Thread Group" should be unchecked.
Add an HTTP request as a child of the Loop Controller.
In the HTTP request, set the path or parameter that contains the order ID to ${order}.
Run the test plan.
By following these steps, JMeter will extract all order IDs from the response headers and use them in separate HTTP requests inside the Loop Controller. The ${order} variable will be replaced with the extracted order ID during each iteration of the loop
Hi Raghav,

Hi Raghav.
What is "Match No. (0 for Random)"? , what's the purpose of it?
I find hard to understand that particular.
Hi Guhan, the match no signifies that if your regular expression matches multiple values, then which one to consider. For example your regex gives 5 matches and you want to extract the 4th value, you will give 4 in Match No. Now in case you want to match any random value out of extracted values, you can give 0.

Maybe there is a post processor I could use to write a script and transform the regular expression variables randomly to a new variable and parse it in the next http sampler. But I am not very familiar with extracting the variable from groovy.

Hii!! I am getting 403 forbidden error for post method it says csrf not found to compare the path! Can you please help
Hi Amulya,
A 403 Forbidden error with a message about CSRF usually means that the application is using CSRF protection, and JMeter is not sending the correct CSRF token with the request.
To fix this issue, you will need to correlate the CSRF token in JMeter and send it with the request. Here's how you can do it:
First, check the response of the login request in your JMeter script to see if the server is sending a CSRF token. Look for a response header or body that contains the CSRF token.
If the CSRF token is present in the response, you will need to extract it from the response using a JMeter extractor. To do this, add a Regular Expression Extractor post-processor to the login request in your JMeter script.
In the Regular Expression Extractor, set the "Reference Name" field to a variable name that you can use later in your script to refer to the extracted CSRF token. Set the "Regular Expression" field to a regular expression that matches the CSRF token in the response.
Add a new HTTP Request sampler for the request that is giving you the 403 Forbidden error. In the HTTP Request sampler, set the path and other parameters as necessary.
In the HTTP Request sampler, add a HTTP Header Manager to set the CSRF token in the request. In the HTTP Header Manager, add a new header with the name "X-CSRF-Token" (or whatever header the server is expecting) and set the value to the variable name you used in step 3.
Save and run your JMeter script again. The CSRF token should now be sent with the request, and you should no longer receive a 403 Forbidden error.
It's important to note that the exact steps for correlating the CSRF token may vary depending on the specific application and how it handles CSRF protection. You may need to consult the application's documentation or contact the developers for assistance in correlating the CSRF token.
Hi Raghav,

Hi Raghav, how can we extract a value from request body and export it in a file?
Hi Saurabh
To extract a value from the request body and export it to a file in JMeter, you can use a combination of a Regular Expression Extractor and a Save Responses to a file listener.
Here are the steps:
Add a Regular Expression Extractor as a child of the sampler that sends the request. Set the following properties:
Name: give a name to the extractor, for example "Extract Value"
Apply to: select "Main sample and sub-samples"
Field to check: select "Body"
Regular Expression: enter a regular expression that matches the value you want to extract. For example, if the value is in a JSON format like {"id":12345}, you can use the regular expression: "id":(\d+)
Template: enter $1$
Match No.: 1
Default Value: leave it empty
Add a Save Responses to a file listener to the thread group or the sampler. Set the following properties:
Filename: enter the filename where you want to save the extracted value. You can use JMeter variables in the filename, for example ${__time(yyyyMMdd-HHmmss)}.txt to include the current date and time in the filename.
Variable Name: enter a variable name for the extracted value, for example "myValue"
Append: select "false"
In the regular expression extractor, add the variable name from step 2 to the "Reference Name" field. For example, "myValue".
Save the JMeter script and run it. The extracted value will be saved in the specified file with the given filename.
Note: If the request body is not in a JSON format or the value you want to extract has a different format, you need to adjust the regular expression accordingly.
@@RaghavPal thanks Raghav. Will check this one. It's was an interview question. I tried almost similar things but didn't select the reg exp as main and sub.

Can you please help me?
Hi Maneka, this should work
^[a-z0-9]{1,40}$
matches a-z 0-9 with length upto 40
In case you want to mactch only length of 40 then use
^[a-z0-9]{40}$
Thanks Raghav.I will try and let you know.

Hi Nitin, for extracting value, you can use correlation as shown in the video or json extractor in case of json response. For the condition you can use IF controller
Hi i have one query without doing regular expression for csrf token also my login is successful shown in jmeter UI,how ever my application logs shows the security denied messages but why jmeter request passed(login) is shown in green instead of orange please answer my query i am a beginner :)
is it because the response code wrongly handled ?
Sandeep, pass or fail is generally decided based on the assertions you have put. It seems you have not put any assertion and the test also did not receive any http error code, so it passes.
Try putting some assertion and check.
Hi who knows how to handle problem when in next iteration the response result is empty due to 304 code (not modified) and an extractor which worked well before is not able to retrieve needed info because response is empty? Thanks
In that case it will fail and it is a valid failure. isn't it

i have query
i have regular expression from my request but how to validate it on another web page.
Hi Raj, what exactly are you trying to do. With regular expression you can extract any text. Now using the variable (used to store the text), you can use it anywhere in your test plan.
hello everyone, I have two scenarios I want to know how can I test that using regular expression extractor.
1) When I have username/password and through that, I can access user's personal data like credit card info and billing details as I am testing a website (so no negative intentions)
2) if I don't have username/password then how can I use JMeter to get personal info?
P.S: I think the second one can be done through SQL injection. even though I don't know how but I think if someone could help me in that too that will be great.
Help please Thanks in Advance
