- Hi Guys!
This video covers the concept of Parameterization, i.e. how to read data from CSV File in JMeter.
Learning:
What is Parameterization?
Parameterization is the process of creating multiple test data for single/multiple users in a test script
Why Parameterization?
Let’s say You have the task to load test the login functionality of the application under test. Since, it is a load test, you can not test it with a single login. In this case, you need to test it with multiple test data and hence you need to use the concept of parameterization.
Steps to parameterize your test data:
1)Put the test data in CSV file
2)Configure JMeter to read those test data from CSV file by adding Config Element - CSV data set config
3)Replace hard coded test data with variable
Fields under CSV dataset config:
1)Filename: This refers to the path to the CSV file which contains the test data
2)File Encoding: The encoding technique by which you want to read the CSV file eg: UTF-8
3)Variable Names: List your variable names(comma separated) to match the columns in the CSV file. You can keep this field empty if you want to use first line of CSV file as variable name
4)Ignore First Line: Set this field to True if you want to ignore the first line of CSV file, else take the default value -False. It is used only if Variable Names is not empty
5)Delimiter: ',' by default, you can set anything else too
6)Allow Quoted Data: Set this field to True if you have double quotes in CSV columns, else take the default value -False
7)Recycle on EOF: Set this field to True if you want JMeter to restart from the beginning when the End Of File is reached, else take the default value -False
8)Stop Thread on EOF: Set this field to True if you want to stop the current thread if EOF is reached; else take the default value -False;
9)Sharing Mode: It selects threads which share the same file pointer

Hi 🙋♂️
All videos are very helpful and easy to understand.
My question is how can we fetch data from csv file for POST request ?
Awaiting for your reply
Thanks 😊
wow, the Sharing Mode drop down options...thanks for explaining them. Now I COmPLEtelY understand it all.
Blazemeter has an excellent blog explaining this. Don't be so hard on the instructor here, as she is only going over the basic just to get you started. Otherwise this video would last for hours in order to go over ever little detail.
Wonderful session .....Is there any online batch currently running for Jmeter? Please provide the contact info
Hello Please help me with query.
What would be the possible failure reason for a script if the environment gets changed for example from UAT env to pre-production environment.
Hello
Jmeter does load and performance testing. The config file is also there but it is only verify the content.
Who verifies or also checks the performance? or uploaded the file and verified its final result for testing purpose what should be done please make sure all the final result and html report is also clear all. Make the fully and concise report with purpose and all..
Hi, In search sampler, Path is - /wiki/jmeter. But when you created record video tutorial(video 03), Path was - /search-redirect.php. Again in video 8 , path becomes - /search-redirect.php. How ma'am?
Hi Mam
Your're really explaining worthy and helpful, appreciated thanks
Thank you so much!

@@qualityassurancelab7764 In CSV file data, can we run these data parallely by putting nos of thread in thread group. For example, if there is 3 values in CSV file and if we pass nof of thread 3 in thread group, then will ittake and execute 3 data of csv file parallely ?
Hi Mam, PLease explain Sharing Mode in detail.what is the purpose of different option provided in sharing mode
you can go to Blazmeter webpage and they do an excellent job explaining it. I agree, she did not explain anything about it at all here but just read the options for us. useless
@@vnecksurferdude7041 That's what I said about Blazmemter's page.
Hi, Thanks alot for this video, I have one question, How can give the image parameter (attributes) in Body Data Like Firstname, Lastname, Profile_image Field for the Post Query in HTTP Request.
Mam, Waiting for your reply.
Hi, you are welcome and apologies for late response.
Checkout this video to work with POST query - ruclips.net/video/fUxLWHZKvmg/видео.html
Quality Assurance Lab mam I watched this video but my question is how to give image file attribute to body data. I want to give path from local directory.
@@uzairsiddiqui6660 Hi, please follow the below steps In HTTP Request Sampler to upload image file:
Step 1: Select the Method as POST
Step 2: Check the box - "Use multipart/form-data for POST"
Step 3: Move to Files Upload ,click on Add and provide below details:
File Path - Provide the complete path of the Image file
Parameter Name - Provide relevant form of “file” type name, eg. imageFile
MIME Type - Provide File's Internet media type. For eg.
For GIF image
, MIME Type is: image/gif
For JPEG JFIF image, MIME Type is: image/jpeg
Please let me know for any further query.
For the "Send Parameters With the Request" section/table, for me if I replace "Value" columns with junk values, but not delete the "Jmeter" in the "Path" field (where it is "/wiki/Jmeter") as you mention at around 5:10, then the execution still takes me to the correct web page. So is my test still valid like this - meaning will my response time still be accurate and resemble how an actual person submits the request? Also, if i do delete "JMeter" in the path, the response also returns the JMeter page (as long as the "search" parameter is "JMeter". But if I also leave the other parameters as junk, it will still work. so this is confusing).
very clear explanation.Tq so much mam...

I have post operations with different payloads each time, how do I config to have multiple payloads to invoke same API?
url: abc.com/testdata
operation: POST
payload1: {"k1":"Have more data here"}
payload2: {"k1":"Have further more data"}
Hi, please follow the below steps:
Step 1: Add multiple payloads - "Have more data here", "Have further more data" etc under the csv file.
Step 2: Add CSV dataset config for the HTTP request and provide necessary field details. Let's say that Variable Names field is PayloadVar
Step 3: Put the payload under Body Data as "k1":${PayloadVar}, where PayloadVar is a variable created in step 2
For any detail to work on APIs(SOAP and REST) in Jmeter, please refer - ruclips.net/video/fUxLWHZKvmg/видео.html
@@qualityassurancelab7764 What if the payload spans thousand of rows and not feasible to be copied in the csv?
