Breaking stuff on purpose primarily in the production environment is one of the mantras in chaos engineering. But when you tell your plan to your engineering manager or product owner, you will often get some resistance.
Their concerns are valid. What if breaking stuff is irreversible? What will happen to the end users? Will our support ticket system get busy?
Recently, Google Chrome 103 was released with a bunch of new features. One of the notable features is the introduction of HTTP Status Code 103. This article will dive into the HTTP 103 status code with a quick demo.
From the Mozilla Developer Network Web Docs, HTTP 103 Early Hints is the information response status code primarily intended to be used with the Link header to allow the user agent to start preloading resources while the server is still preparing a response.
Everyone deserves the right internet speed and everyone wants the best bang for a buck. To ensure our internet bandwidth, we all run speed tests from our Internet Speed Provider or public speed test tools like fast.com or speed.cloudflare.com and more. But do we know how the speed got measured under the hood? In this blog post, we will see how the Internet Speed Test works?
The Internet Speed Test helps us to understand how fast our internet connection is. It is primarily based on Download and Upload speed, usually measured in megabits per second (Mbps), but varies based on which tool you are using. One megabit is equal to 1,024 kilobits.
In my last post, we discussed how to upload files to AWS S3 in JMeter using Groovy. We have also seen Grape package manager on JMeter. Recently, k6 announced its next iteration with many new features and fixes. In this blog post, we will see how to upload files to AWS S3 in k6.
k6 0.38.1 is a minor patch. To view all the new features, check out the k6 0.38.0 tag. Following are the noteworthy features in 0.38.0.
I use my personal AWS S3 to store all my personal and confidential documents. There are three primary reasons for choosing AWS S3: affordability, speed, and reliability. If you are working on the AWS cloud, the usage of S3 is inevitable. S3 plays a critical role in storing objects in hot and cold storage. Sometimes you need to upload a payload or file objects to S3 programmatically via your performance test script. This article will help you to upload files to AWS S3 in JMeter using Groovy.
Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance.
I have been posting multiple videos about the Performance Engineering Series on the QAInsights channel, which will help you to get started with troubleshooting Java applications. In this blog post, we are going to see how you can use Eclipse Jifa to identify potential performance bottlenecks in your Java applications. Let us get started.
Eclipse Jifa (Java Issue Finder Assistant) is an open-source application to troubleshoot Java applications. The inception phase of Jifa was back in 2020 by Alibaba under the Eclipse Foundation. Developers from Netflix, Alibaba Cloud, and other developers are contributing to the Jifa project.
The Apache JMeter community has been swift in releasing the major security patches for the Log4j fiasco. I have already covered multiple posts about Log4j vulnerability, JMeter 5.4.2 and JMeter 5.4.3. JMeter 5.5 was supposed to be released in the last quarter of 2021. I have already covered what's new in JMeter 5.5. JMeter 5.5 will be released in early January 2022. In this blog post, let us deep-dive into one of the important features, which is the Open Model Thread Group in JMeter 5.5.
Open Model Thread Group is available starting from JMeter 5.5 under Threads menu when you right click on the Test Plan as shown below.
A new sheriff in town. Microsoft launched the fully managed Azure service for performance test engineers and developers to perform high scale load testing called Azure Load Testing, currently in preview mode. It is quite a big announcement for performance engineers. Let us see whether Azure Load Testing fulfills our needs or not in this blog post.
As foretold, aptly put, Azure Load Testing is an offering for the customers who are in the Azure ecosystem. Even if you are not in Azure, you can still spin up the load test resource for performance testing. But the catch is PRICING. We can discuss the pricing in another blog post. Let us focus on the features, how to get started, and more.
There are umpteen tools available to check the internet speed. SpeedTest, Speed from Cloudflare, Netflix's Fast, or if you use Google search, you can test the internet speed and its analytics. In macOS Monterey, Apple has released a command-line tool called networkQuality. In this blog article, we will deep dive into network quality and its usage.
The only prerequisite to launch networkQuality is macOS Monterey. Launch the terminal from the Finder. In the terminal, type networkQuality and hit enter.
There are over 50+ tools and solutions available in the market for performance testing your application and services. Now it is time to check out Ddosify, a high-performance load testing tool that offers free and commercial features to test web applications and services over HTTP(S), HTTP/2, and other protocols are on their way. In this blog article, let us deep-dive into the Ddosify tool and see whether it satisfies a typical performance engineer or not.
Before we see Ddosify, let us try to understand the name of the tool. Ddosify contains Ddos term. DDoS stands for Distributed Denial of Services. Below is the Wikipedia entry for Denial of Service:
So, you want to learn about performance testing and progress towards performance engineering or DevOps or Site Reliability Engineering. I get it. Jumping directly into performance testing might be overwhelming. I was directed to learn the tool, then the performance concepts. It is like, learning to swim by directly jumping into the pool. Either someone needs to save you from drowning if things go south, or if you are smart enough, you can manage. I was able to manage myself to learn the performance concepts parallel while learning the performance testing tool around a decade ago.
I do not want you to go down that route. In this blog post, I am going to list ten things you should learn before learning about performance testing and its tools. There is no end to learning stuff. But I have highlighted the essential and fundamental concepts you may need to go through for your performance testing trip.
If you are reading this blog post, most probably you are planning or already planned or just getting started with Apache JMeter. Learning any performance testing tool could be challenging. Sometimes the technical documentation looks abstract, and the learning curve could be steep. In this blog post, I am going to list out five things to know before learning JMeter.
If you consider almost any performance testing tool, it will not execute JavaScript. HTML, CSS, and JavaScript are the essential components for any web page/app. If your application has JavaScript functions embedded in the page, JMeter will not execute that.
Data is ubiquitous. Shiny from R Studio helps to build interactive web applications from R. But, performance testing is a little tricky. If you sniff the traffic, you don't get any network data. If you are working on Shiny apps performance testing, then this blog article is for you. This blog article explains load testing shiny apps using shinyloadtest package.
Shiny is an R package that makes it easy to build interactive web apps straight from R. You can host standalone apps on a webpage or embed them in R Markdown documents or build dashboards. You can also extend your Shiny apps with CSS themes, htmlwidgets, and JavaScript actions.
In this blog post, we are going to deep-dive into the HTTP Toolkit and its features. As performance engineers, it is our responsibility to learn various tools and technologies. Based on the issue, you need to leverage the right tool to fix the problems, just like plumbers. Let us see HTTP Toolkit for Performance Engineers.
It is an open-source tool to debug, test, intercept HTTP(S) requests. It can intercept desktop browsers such as Chrome, Firefox, Edge, etc., Android apps, Python, Java, Ruby, and all terminal-based apps, and Electron apps.
Welcome to Learn JMeter Series! This series helps you to learn Apache JMeter in a much simpler way with the relevant examples and exercises. This tutorial focuses on Recording on JMeter.
To get started with application performance testing, the first step in JMeter is recording your business transactions. Recording the business flow helps to expedite the process of creating test plans. Otherwise, you will be spending more time manually crafting the requests.
