Thanks for the video. By watching this video I understand that need to learn joins, order by and clause commands As a performance tester is there are any other commands should we learn for database testing using JMeter please. Please help me in learning the database testing and for the interview purpose
Sure bro, will do
thanks sir for this content
You welcome
Hi, Azure Load testing URL based is the part of SRE or QA Testing team?
Both
Hi, I have a concern as below: - Little's Law is applying for closed workload model, but irl most of the system are open workload, or at least partially open workload. How can you calculate TPS/RPS for this type of workload model? - Moreover, TPS/RPS distributions are not equal on APIs, so can you also share how to do calculations on these too ?
Hi Basant could you help me to know suppose you have single script,and you want distribute the load percentage wise for each transactions what we did using Throughput controller or in load runner using blocks...how to perform this scenario using neo load
Please use loop for transactions
@@littleslawyoutubechannel there is no way we can put % like lr nd jmeter
For scripts you can do not for transactions , if I am not wrong
I tried to record android application .But doesn't work.Do you have any solution for this?
Let me check
Can you pls suggest on following question : Suppose we have requirement of executing performance tests with 20,000 virtual users (VUs) but we have a license for 10,000 VUs, in that scenario what is our approaches & strategy
I would suggest to know that instead of virtual users try to narrow down the number of TPS you need to achieve? Try to adjust pacing and think time to achieve more TPS with less resources (It should be realistic). Then extrapolate the results from NFT to prod instead of testing completely. (if you don't have the license for the 20K users)
Excuse Sir, where did you get the CPU, Network and Memory Metrics? in the View Results Tree? thanks for the video!
thanks bro
You welcome bro
Which emulator are you using in this video ?or is it your mobile window.How to show this in our system.PLease explain i'm beginner in mobile app performance testing
I have used my iPhone
Waste fellow, u don't know how to create a workload model but u are populate misinformation
how can i get this new 54 file
You can download this from the github repository I showed you
ya i got it now.Thankyou

Hi sir, really useful video. I have one doubt, can you pls clarify. How to get the browser specific User Agent Value?
I will let you know shortly. Thanks
Hello Sir I have a question regarding the volume of data Should we seed have exact volume of data as prod ? For eg) want to test how search functionality is working say in prod, there are 10k products do we have to seed 10k product in test env ? In that case cost of setting up database will increase in test env Or can we have around 5k product in test env and we have to do some math for calculating response time in real scenarios ? Which one is ideal to do ?
Let me check and get back to you . Thanks
Hello Is there any possible way to take the TTFB when a request is sent?

Hi Sir. I have a usecase on concurrency testing For eg: let's have PUT method (/api/id) in which we will replace the id with csv of multiple ids "say 30" which will runs through the API. I need to make this call to trigger at the same time which means no need of ramp-up time or ramp-up step just need to trigger parallel. How to achieve this.
Use thread group and make ramp up time to 0
@@littleslawyoutubechannel tried this already sir. But it is not triggering as per the requirement. I have triggered the same api in 30 threads in a thread group it has triggered all the requests sequentially that shouldn’t be the case. If I triggered 30 requests it should trigger at a same time (in one second) and only 20 requests will be get triggered successfully remaining should be failed as we have designed only 20 apis call can be concurrently made in one second.
