Reading Time: 4 minutes Hello everyone ! I hope you are doing well in this pandemic of COVID-19. In the previous blogs, we saw how we can extract the data from Jmeter using post-processor- JSON Extractor. Here in this blog, we will see other post-processors like Regular Expression. Many of us feel that creating regular expressions is difficult for non-technical people. So most of us avoid using regular expressions Continue Reading
Reading Time: 3 minutes Hello there, In this blog, we shall discuss about the WebSocket protocol. Further in the blog we will also try to learn to create a simple Gatling Scripts for this protocol as well. But without jumping to the Gatling script we shall learn about WebSocket Protocol. So lets begin. How webSocket is different from HTTP? WebSocket and HTTP, both of these are communication protocols which Continue Reading
Reading Time: 3 minutes Hi Guys, In this blog, we shall discuss about the SSE(Sever-Sent Events) protocol. Further in the blog we will also try to learn to create a simple Gatling Scripts for this protocol as well. Let’s not jump directly to the script part, but first let us learn about the SSE protocol and how it is different from WebSocket protocol. How SSE protocol is different WebSocket Continue Reading
Reading Time: 4 minutes Hello Everyone, In our previous blog post Gatling feeders and feeder strategies we have discussed what are the different ways to inject the data in our simulation from different data sources. Today we will discuss: Real-time use case (Problem Statement) Solution: Gatling Session and Session API Injecting Data with Gatling session API Extracting data with Gatling session API Some common exceptions Real-time use case (Problem Continue Reading
Reading Time: 5 minutes Hello, welcome to the first blog of our Gatling series. Objective is to see how we can accelerate the performance of the product with a tool like Gatling and how to easily integrate with our code base to run the test on different environments. This series is totally based on my personal experience so I have tried to cover all the possible scenarios that I Continue Reading
Reading Time: < 1 minute Hi all, Knoldus has organized a 45 mins session on 23rd March 2018. The topic was Boost your App with Gatling. Many people have joined and enjoyed the session. I am going to share the slides here.
Reading Time: 2 minutes Email notification, send email and retrieve email is a important part of any company or organisation so if you have your email server and want to know the email performance of email server then we can use the jmeter. Beauty of jmeter is it gives the power in your hand you can measure the performance of send email same as received email performance.So we can Continue Reading
Reading Time: 2 minutes This is last blog of this series in this we will read how to monitor CPU Utilization by Dynatrace. Why we always need memory analysis ? We need memory analysis is to optimize garbage collection (GC) in such a way that its impact on application response time or CPU usage is minimized. If garbage collection has a negative impact on response time, our goal must be Continue Reading
Reading Time: 3 minutes In my Last blog, we went through the introduction of Dynatrace Digital Performance tool. In this subsequent blog, we will learn how to diagnose this tool. Once you open the Dynatrace client, you will be landed to a dashboard page where you can easily view recent activity of all the requests to the server (picture given in the last blog). We can easily connect with different hosts by Continue Reading
Reading Time: 2 minutes Hi Everyone, In This blog we will discuss about a performance tool – Dynatrace which we are using now-a-days in Knoldus for Performance Testing and We would be running this blog as a series and we would be looking at various aspects of Performance Testing with this blog. The aim includes; What is Dynatrace? How does this work? Benefits of Dyntrace When we develop a new application, we Continue Reading
Reading Time: 2 minutes I have started working on a project which require stress testing using Gatling. I Setup the sbt project on which gatling is working fine. But when I try to integrate it using play framework, it doesn’t work. The project structure for both are different so it doesn’t work for both the project in the same manner. Your build.sbt should be like this: import _root_.io.gatling.sbt.GatlingPlugin import Continue Reading
Reading Time: 3 minutes In this blog we are walking through how to improve performance of application using Yourkit profiler it is helpful for both Tester and Developers. Your Kit is big achievement in the evolution of the profiling tools. It is intelligent tools for profiling java , .net and ( JVM support languages) based applications. It is often important to check memory usage and memory used per process on servers Continue Reading
Reading Time: 2 minutes When we talking about Performance Testing, Some time we faces the scenario like we have to extract data from file. Extraction data from file is very important part of performance testing. In this blog, we will learn Data Extraction from File using Jmeter. First of all we will create a .xlsx file. which consist our test data. Now we open the jmeter and make a Continue Reading
