[@GautamKumar-dg8qc]

Hi thanks for the video I have one doubt as you mentioned that 3 rows are there so we took 3 iterations, what if we take the iterations as infinite then it will repeating again again right. Like 1,2,3 then 1,2,3... and so on infinitely right?

[@RaghavPal]

Gautam Yes, you're correct. When you set the iterations to "Infinite" in the JMeter CSV Data Set Config, it will continuously repeat the rows in the CSV file, effectively creating an endless loop. Here's a detailed explanation of how it works: 1. CSV Data Set Config Setup: - You add a CSV Data Set Config element to your test plan. - You specify the path to the CSV file containing the data rows. - You set the "Recycle on EOF?" option to "True" (this is the default). - You set the "Stop thread on EOF?" option to "False." - You set the "Number of threads" (virtual users) to your desired value. - You set the "Loop Count" to "Infinite." 2. Iteration Process: - JMeter starts reading data from the CSV file, feeding it to each virtual user. - When it reaches the end of the CSV file (EOF), it rewinds to the beginning and starts reading again, continuously repeating the rows. - This cycle continues indefinitely, as long as the test is running and the "Loop Count" is set to "Infinite."

Hi Raghav, Do I need to parameterize login credentials(giving say 20 username and password in csv file, so that each login attempt will be from different user) when I do load testing for an application?

[@RaghavPal]

Hi Anila, it depends, usually people do this to get a realistic scenario. If the same user logs in there may be a chance of cache and memory built up, but that can be taken care by using Cache and cookie manager

[@anilaantu5972]

@@RaghavPal Thanks Raghav. Cookie and cache can be managed by config elements right? But do we need to take care of SSO while attempting different logins? How can I give variable names like in this video? Could you do a quick video on that? Please.

[@PrincetonKurtz-zn9qv]

Hi Raghav ,Suppose for multi user load test I want to login with different usernames & passwords from CSV file then what values should be under "Variable names " box ? I should left it blank ?

[@RaghavPal]

Hi Princeton In JMeter, when you want to use different usernames and passwords from a CSV file for a multi-user load test, you need to specify the variable names that correspond to the columns in the CSV file. Here's what you should do: 1. Create a CSV file with columns for usernames and passwords, for example: ``` username,password user1,password1 user2,password2 user3,password3 ``` 2. Add a CSV Data Set Config element to your Test Plan in JMeter. 3. In the CSV Data Set Config element, set the "Filename" field to the path of your CSV file. 4. In the "Variable Names" field, you should enter the names of the variables that correspond to the columns in your CSV file. For example, if your CSV file has columns named "username" and "password", you should enter `username,password` in the "Variable Names" field. Make sure the names match exactly (case-sensitive). 5. In your HTTP Request, use the variable names in the format `${variable_name}` to refer to the values from the CSV file. For example, if you want to use the username and password values from the CSV file, you can use `${username}` and `${password}` in the appropriate fields of the HTTP Request. By setting the correct variable names in the "Variable Names" field, JMeter will automatically read the values from the CSV file and assign them to the corresponding variables during the load test. Each thread/user will then use a different set of credentials from the CSV file.

It is possible to set variable "http request" type by csv-file? For example GET, PUT, UPDATE and so on

[@RaghavPal]

When using JMeter with a CSV Data Set Config, you can indeed set the HTTP request type dynamically based on values from your CSV file. Let's explore how you can achieve this: 1. CSV Data Set Config: - The CSV Data Set Config element in JMeter allows you to read lines from a CSV file and split them into variables. - By default, it assumes that the CSV file is comma-separated (CSV), but you can customize the delimiter. 2. Scenario: - Suppose you have a CSV file with columns like `RequestType`, `Endpoint`, and other relevant data. - You want to dynamically set the HTTP request type (GET, PUT, etc.) based on the `RequestType` column from the CSV. 3. Steps: - Here's how you can achieve this: 1. Create Your CSV File: - Your CSV file should include columns like `RequestType`, `Endpoint`, and any other relevant data. - Example: ``` RequestType,Endpoint GET,/api/resource1 PUT,/api/resource2 POST,/api/resource3 ``` 2. Configure CSV Data Set Config: - Add a CSV Data Set Config element to your JMeter test plan. - Specify the path to your CSV file. - Set the delimiter to match your CSV file (e.g., semicolon `;` in your case). 3. Use Variables in HTTP Request: - In your HTTP Request sampler, use variables for the request type and endpoint. - Example: - Set the HTTP Method field to `${RequestType}`. - Set the Path field to `${Endpoint}`. 4. Run Your Test: - JMeter will read the values from the CSV file line by line. - For each iteration, it will set the `RequestType` and `Endpoint` variables accordingly. - Your HTTP requests will use these dynamically set values. 4. Example: - Suppose your CSV file contains the following lines: ``` RequestType,Endpoint GET,/api/resource1 PUT,/api/resource2 POST,/api/resource3 ``` - During execution, JMeter will use the values from the CSV to make requests like: - GET: `/api/resource1` - PUT: `/api/resource2` - POST: `/api/resource3` Remember to adjust the column names and structure according to your specific use case. With this approach, you can dynamically set the HTTP request type based on values from your CSV file.

[@pradyumnavaradpande3688]

Hi Raghav, Really great videos! Thank you so much for sharing! I would like to know, how can we insert response assertions to check our results. In this video, we have used 2 loop so we will get two different results. 1. now if I want to use response assertion 1 for first value which is coming from csv. 2. And response assertion 2 for second row value from csv. How to do this? Could you please help me ?

[@RaghavPal]

Hi Pradyumna, Can you not add the assertions in diff columns of same row. It will be easier that way

[@pradyumnavaradpande3688]

​@@RaghavPal Hi Thanks for your prompt response. As per your suggestion, I should add variable in my request then same variables should mention in (Jmeter variable Name to use) field in response assertion. am I right? but what I want to achieve is that, there are total 5 rows in csv for first 3 values when executed in database it should get updated and I get the status as updated but for last 2 values I should get error code

[@RaghavPal]

Hi Pradyumna, I may get more information about your scenario if I take a deeper look. But for general, The way parameterization works is you create variables and refer the variables from an external location. If the variables is provided multiple values, the test runs multiple times with each row or set of data, Now this is the standard way. You can write scripts to do this in a diff way as required.

[@pradyumnavaradpande3688]

​@@RaghavPal Thank you so much Raghav! Now I am able to validate it by adding Beanshell Assertion but while exporting results and I still believe that I am not using the jmeter options properly. can you please help me? Please let me know if you need any further information, I will share with you

[@RaghavPal]

Happy to know that Pradyumna. I will suggest that you first check the required information online As I might not get enough time to go deeper into the setup

Hello Raghav, I am looking for your help on JWT token. How do Generate JWT token using Jmeter? I have used JWT Pre-Processor and it did not help me. Thank you in advance for your help

[@RaghavPal]

Haresh Before we dive into generating a JWT token, can you please provide more information about the token you need to generate? Specifically: * What is the algorithm used for signing the token (e.g., HS256, RS256)? * What are the claims or payload elements required in the token (e.g., username, email, expiration time)? * Do you have any specific headers or custom fields that need to be included in the token? Choose the Right Approach Since you've already tried the JWT Pre-Processor, we can explore alternative approaches. We can use either: * A Beanshell Pre-Processor * A JSR223 Pre-Processor (with Groovy or JavaScript) Both of these options allow us to write custom code to generate the JWT token. Step 1: Write the JWT Token Generation Code Let's use a Beanshell Pre-Processor as an example. We'll use the `java-jwt` library to generate the token. Add a Beanshell Pre-Processor to your JMeter test plan and paste the following code: ```java import io.jsonwebtoken.Jwts; import io.jsonwebtoken.SignatureAlgorithm; // Set your secret key (replace with your own) String secretKey = "your_secret_key_here"; // Set the payload claims (replace with your own) String username = "johnDoe"; String email = "[e-mail]"; long expirationTime = 3600000; // 1 hour // Create the JWT token String token = Jwts.builder() .setSubject(username) .claim("email", email) .setExpiration(new Date(System.currentTimeMillis() + expirationTime)) .signWith(SignatureAlgorithm.HS256, secretKey) .compact(); // Store the token in a variable vars.put("jwtToken", token); ``` This code generates a JWT token with the specified claims and signs it with the provided secret key using the HS256 algorithm. Step 2: Use the Generated Token in Your Request Now that we have generated the JWT token, we need to include it in our request. You can do this by adding a `Header Manager` to your request and setting the `Authorization` header to `Bearer ${jwtToken}`. That's it! Run your JMeter test, and the JWT token should be generated and included in your request. -

[@EvergreenWonders]

Excellent session. loved it. Sir, can we have a session on how to write to CSV file using Jmeter, please.

[@RaghavPal]

Hi Vikas, thanks for the message. Usually we can export results in csv, Is there any specific use case for your example

[@vinay24c]

Hi Sir, Thanks for your videos. I want to substitute (example 10 unique data) in my single request like each occurrence in LoadRunner, is there any way to achieve the same in JMeter, please assist it.

[@RaghavPal]

Vinay Yes, there are a few ways to substitute different data in a single request in JMeter. One way is to use the *CSV Data Set Config* element. This element allows you to specify a CSV file that contains the data that you want to substitute. The CSV file should have one row for each data point, and the columns in the file should match the names of the variables in your request. To use the *CSV Data Set Config* element, you need to add it to your test plan and then configure it with the path to the CSV file. You can also specify the delimiter that is used in the CSV file, and the number of rows that you want to read. Here is an example of how to use the *CSV Data Set Config* element: ``` ``` In this example, the CSV file is called `data.csv` and the delimiter is a comma. The `numberOfLines` attribute is set to 10, which means that the element will read the first 10 rows of the file. The data in the CSV file will be substituted into the variables in your request. For example, if your request has a variable called `username`, the value of the `username` variable will be replaced with the first value in the first row of the CSV file. Another way to substitute different data in a single request is to use the **BeanShell PostProcessor** element. This element allows you to execute a BeanShell script before or after a request is executed. The BeanShell script can be used to read data from a file, generate random data, or perform other operations. The data that is generated by the BeanShell script can then be substituted into the variables in your request. Here is an example of how to use the *BeanShell PostProcessor* element: In this example, the BeanShell script is stored in the `script` attribute. The `script` attribute can contain any valid BeanShell code. The BeanShell script can be used to read data from a file, generate random data, or perform other operations. The data that is generated by the BeanShell script can then be substituted into the variables in your request. I hope this helps

[@sanketnegi1]

Great learning.. But I have a doubt.. I want to execute each iteration with a different column value.. in while controller.. can you tell how can I do it?

[@RaghavPal]

Hi Sanket, I will need some details, Let's say in your csv file you have a column "username" and in your requests you have a variable called "username" Now when you parameterize using csv, on execution, it will take values from username column. and will take the next row in each iteration, So you can add the values you need in the new rows. Now what exactly from here do you need

[@sanketnegi1]

@@RaghavPal So I have columns username1 username2 and username3 Now in while controller (which will run thrice) I want to use username1 in the first loop, Username2 in second loop and username3 in the third loop. Also I just noticed while controller runs just once every thread. So if we use loop 10 with thread 1 it will just go inside while controller only once.

[@RaghavPal]

I believe username1, 2 and 3 are all used in the same place in request, if that is true, you can keep a single column and add all the values in sequence

Raghav, thank you so much for not only sharing your knowledge but being a good teacher! I have never done any load test before and my application is pretty much similar to gmail in the sense that I need to login, do some search, send some emails, upload/download some files. My task is to see how the app behaves with some 7000 concurrent users (given that certain percentage of users would take certain actions as listed above.)My question is: Do I need to use parameterization for the 6000 users here? Or simply raise the number of threads to 7000 would be enough to say it's a load test? If parameterization is needed, I guess I have to create 7000 users first in the database BEFORE even create a test plan in JMeter? Could you please give me some guidance !! Thanks a bunch!!

[@RaghavPal]

hi Lily, i am glad that you are learning from this channel. If your aim is just to load test the application you can go with same user and increase number of threads. Some tips: Always use a stable client for this test. Preferably a remote(cloud) machine. This will not compromise your network during the test + you can compare your future runs on the same configuration. Always note down client and server configuration.

[@sayantandas2054]

Hi. In case of some logins they provide an access id for the entire session . Now , using regex extractor post-processor i extracted it and used it in my subsequent http samplers as ${token} (i am conducting a web test which has multiple http samplers , first one being login get request which generates access token for that login). Works for 1 user(thread). However, when i use multiple threads , for some threads it works and for the remaining ones the request token uses "${token)}" as its value not the value of the token which it did in case of one thread. Can u pls help me fix this?

Hi If i want run only one iteration and with 3rd row testdata then how can i do that?

[@RaghavPal]

Hi To run only one iteration and with 3rd row test data in JMeter, you can do the following: 1. **Open the JMeter test plan.** 2. **In the `Test Plan` element, right-click and select `Add` > `Sampler`.** 3. **From the list of samplers, select `HTTP Request`.** 4. **In the `HTTP Request` dialog, enter the URL of the web page that you want to test.** 5. **In the `Test Data` tab, select the `3rd row` from the `Data Set` list.** 6. **In the `Iterations` field, enter `1`.** 7. **Click `Save`.** Once you have made these changes, JMeter will only run the HTTP Request sampler once, and it will use the data from the 3rd row of the test data set. Here is an example of how to do this in JMeter: ``` HTTPSamplerProxy sample1 = new HTTPSamplerProxy(); sample1.setUrl("www.example.com/"); sample1.setMethod("GET"); sample1.setTestData("3rd row"); sample1.setIterations(1); ``` Once you have added this code to your JMeter test plan, you can run the test by clicking on the `Run` button. The test will only run once, and it will use the data from the 3rd row of the test data set. I hope this helps
