Is it better to assess performance during development process or at the end? – Difference between Agile and Waterfall approaches Teams must identify at what point in the development process they will benefit the most from doing performance tests while considering the performance of existing systems or those constructed from the ground up. So, the goal of this post is to answer the question of whether we should start performance testing early on, alongside development (as in the agile approach) or later on (as in the waterfall style). Basically, difference between agile and waterfall approaches on performing performance [...]

Today's apps are rapidly evolving, and consumers expect lightning-fast performance. Most users will exit an app if it does not load within a few seconds, regardless of how attractive its design is. The only method to avoid being a part of this club is to do essential performance testing, which is often one of the last steps in the application development cycle but should be completed as quick as possible. Taking this into account , this post outlines the top ten frequent performance testing mistakes that contribute to poor performance testing quality, as well as how these issues may be resolved appropriately [...]
Load test and performance test allow you to see the status of your services and the bottlenecks of these services, if any. In addition, Application Performance Management Tools (APM) provide you with database operations in your services, response times of your APIs, etc. along with many parameters where you are having trouble in details. At Loadium, we offer the support of New Relic and AppDynamics APM tools. What Is The Application Performance Management? APM enables business-critical applications to monitor performance metrics, receive timely alerts in case of performance issues, and generate reports for periodic performance analysis. In this way, it facilitates [...]
Load testing and Performance testing are important for discovering bottlenecks in your system and determining the load capacity it can handle. Most of the time, it is necessary to carry out these tests behind the firewall of companies for data privacy and security. Loadium provides On-Premise Load Generator solution to run performance testing behind firewall. What is On-Premise Load Generator? Our service that creates the load on the servers in your tests with Loadium is called Load Generator. In standard tests, Load Generator is located on Loadium servers. It runs the tests in its environment and creates [...]
Performance Test Reporting step provides an overall test result, test analysis, and recommendations to the development team from the application’s performance perspective. Sometimes, technical teams may underestimate the value of reporting, mostly because they are busy, and writing a good report sometimes just takes more time than expected. What Is Performance Test Reporting? Performance Test Report makes performance testing visible and helps to find bottlenecks and make the GO / NO-GO decision for the whole application or a specific business flow. There are many ongoing forum discussions about what the ideal load testing report needs to contain. While there may not be much agreement over the perfect performance report, you [...]
Selenium WebDriver is an automation tool for web applications. It can operate on Chrome, Firefox, Safari, Internet Explorer and many other browsers via its driver ecosystem. JMeter, on the other hand, is a Java-based performance testing tool. They are both open source defacto tools for testing teams. In case you have your automated integration test, why not use them as a performance test script? This time, we will look into how to execute performance test with Selenium. JMeter has a WebDriver plugin to support Selenium based scripting. You can download this plugin by JMeter Plugin Manager. JMeter supports running [...]
Performance testing is the process of determining the speed, responsiveness, and stability of a computer, network, software program or a device under a workload. In order to conduct and analyze a good load test, you need to understand the performance testing terminology including connect time, latency, etc... Let’s elaborate on what they mean. Connect Time Connect time is the time taken to establish a TCP connection between the server and the client. TCP/IP model guarantees delivery of data by its nature by using TCP Handshake. If TCP Handshake is successful, then the client can send further requests. That data send/receive [...]
There are many open source tools and paid solutions to perform load tests efficiently. As Loadium until now, we supported Apache JMeter and Selenium-based tests for load testing. Gatling, a load test tool, is on the market for a few years and it’s a mature performance test tool to use. In the near future, we are going to support Gatling tests. Let’s discuss the pros and cons of Gatling together. If you want to add more please feel free to add comments below or shoot us a message through our contact page. First, it is an open source load testing [...]
Application performance management is the real time monitoring and management of performance and user experience of software applications. Speed is everything in today’s connected world. Especially when it comes to the applications and websites accessed by end users, it’s much more crucial. Users are not tolerant to slowness. They tend to abandon the application and move on to a similar app if it’s possible. So it will have a huge negative impact on business productivity, profits and even the brand itself. To be successful, velocity and stability should be in balance. IT disaster reports states that stability varies significantly between [...]
Postman is an open source API testing tool. It can work with any given endpoint even if it’s Restful or XML based. It has an easy to use interface to make the request to the given endpoints. It offers a rich variety of features. Creating a collection from requests, extracting data from any response and storing in a variable are the least you can do with Postman. Postman supports any HTTP request type like the POST, PUT, GET, etc. Let’s see what the key features of a POSTMAN request are. Postman request consists of 5 different sections Authorization The [...]
