What Is Load Testing? How it Works

Additionally, the data from agile tests helps inform the baseline metrics used in load testing. Load testing is important because it identifies points of failure in your system and can also show you how your site degrades as more simultaneous users are added. If you know what your peak traffic should be, load testing gives you greater insight into how your web app or site will perform once that level of traffic is reached. Often, load testing is performed right before the release of a new product, a new campaign, a major event, or a system update. Since the goal of load testing is ensuring the website infrastructure can handle an expected number of users, this may not give you enough time for responding to load testing results.

Why is Load Testing Important

Stress testing is a type of performance testing that focuses not just on the expected load, but on extreme load. It’s about taking your site or app to the breaking point and observing recovery. We’re also working on developing scheduled automated load testing that generates reports so we can monitor and track performance over time.


The term “load testing” is often used synonymously with concurrency testing, software performance testing, reliability testing, and volume testing for specific scenarios. All of these are types of non-functional testing that are not part of functionality testing used to validate suitability for use of any given software. With logging frameworks, it has become easy to generate log entries and then troubleshoot problems with the analytical tools.

Why is Load Testing Important

Customer satisfaction is critical for the success of your business. That is the whole point when load testing or API monitoring your website and applications. load test definition As stated before, the more you can ensure your site and applications perform well, the more likely customers will revisit a site or re-enter an application.

How Do You Perform a Load Test?

For instance, a banking application generated various queries related to customer requests, third party transactions, generating OTPs, requests from customers, and so on. This requires tremendous processing power and generation of database requests from the application. While Digital Transformation takes the virtual world by jet-speed, consumer-driven businesses continue to struggle and catch up with the rampant changes and competition. There is no choice for enterprises of all shapes and sizes but to deal with the growing customer expectations and align with them digitally for offering a seamless experience. Mobile Applications are being built on the basis of demographics, future outlook, location, target audience, revenue model, usage patterns, and much more that might seem technically logical at that moment.

In this case, load testing will help you to ensure that it will perform flawlessly under a larger load as well. Development and operations teams should check for security gaps; conduct load testing; assess scalability; consider UX; and map servers, ports and paths. Scalability testingmeasures performance based on the software’s ability to scale performance measure attributes up or down. For example, testers could perform a scalability test based on the number of user requests. The Supply of Machinery Regulation 1992 UK state that load testing is undertaken before the equipment is put into service for the first time. Performance testing applies a safe working load , or other specified load, for a designated time in a governing test method, specification, or contract.

Easily Deploy Load Testing with the LoadRunner Family

The EveryStep Web Recorder is a free web-based scripting tool that records every step of a web transaction and replays the script using a real browser. Record multi-step test scripts of the critical and complex actions your users make, such as button clicks, menu selections, https://globalcloudteam.com/ form submissions, shopping cart process, text inputs, as well as image and text validation. Load testing is the process of testing software performance under a specified load. But on the morning of their Black Friday sale, their site experienced significant slowdowns.

JMeter plugins provide flexibility in load testing and cover areas such as graphs, thread groups, timers, functions and logic controllers. JMeter supports an integrated development environment for test recording for browsers or web applications, as well as a command-line mode for load testing Java-based OSes. Applications are information-intensive and there is a massive exchange of data that takes place to ensure enhanced user experience. Load Testing helps to draw attention to any issue that might hinder the application’s seamless performance, or identify any bottleneck that might occur due to excess load on the software of the application. The application under test is tested for assessing and reporting its behaviour under any expected/unexpected load. In a way, end user response times are reported, as against the business processes, CPU, and memory statistics.

Why Load Testing is Important: The Taylor Swift Debacle

These aspects enable teams to execute the right tests and get credible results from the testing activity. In some cases the load that the application might get cannot be predicted, so the tests have to be built keeping in mind some random pressures and variability in testing strategy. This results in building the right approach, and reduces the number of surprises when the application goes into production.

Why is Load Testing Important

Load testing mimics the way a system or application acts when deployed as a finished product. It can also help identify issues like pages not loading correctly, lag time, downtime, and overall performance problems. LoadRunner, developed by Micro Focus, tests and measures the performance of applications under load. LoadRunner can simulate thousands of end users, as well as record and analyze load tests. As part of the simulation, the software generates messages between application components and end-user actions, similar to key clicks or mouse movements.

Load test before high traffic events

They realized they’d not load tested their site search and filter features, focusing on traffic volume rather than behavior. Similarly, British ecommerce brand LeMieux load tested their site ahead of their biggest Black Friday sale yet. They determined exactly what they could handle, then set up a virtual waiting roomand set the outflow from waiting room to site at that rate.

  • It entails the creation of virtual user scripts, which comprise the numerous duties that each virtual user performs.
  • Often, load testing is performed right before the release of a new product, a new campaign, a major event, or a system update.
  • The goal of load testing is to identify bottlenecks and determine the maximum number of users or transactions the system can handle.
  • Easy to understand for the tester, even with the less experience testers.
  • And not all of them describe what user behavior is being tested in the first place.
  • Response time, or latency.The amount of time elapsed between a user-entered request and the start of a system’s response to that request.
  • Hence, they cannot afford the application to break down regularly due to excess load.
