- What is Load Testing?
A load test is a process that measures the capacity of a system by applying an increased workload to it. The goal of load testing is to determine how much work the system can handle before it fails. Load tests are performed to ensure that the system can handle peak loads and that it has enough capacity for future growth. When comparing a stress test vs load test, remember that both are crucial to the product’s capacity. Load testing helps you understand whether the software is reliable under a predicted load whereas stress testing goes beyond peak levels and tests how the system reacts to loads it is not supposed to handle.
Through specialized testing software, load testing places a simulated “load” or demand on your web application to ensure it remains stable during operation. During a load test, testing software will measure the capacity of your web application via transaction response times. Benchmark testing is the practice of comparing application performance against specific pre-defined industry or organizational standards and requirements. Like baseline testing, benchmark testing includes measuring and recording performance of hardware, software, and network conditions. Benchmark testing helps to measure the quality of service for an organization’s own requirements or against other organizations.
Why run load tests?
It works for applications with huge daily traffic and simulates many virtual users to perform real-time load testing. Important features include scalability checks on web and mobile applications and reporting for performance data under load tests. Load testing and stress testing are part of the software performance testing process—however, each one focuses on different areas of web application performance. A stress test is a type of performance test that checks the upper limits of your system by testing it under extreme loads, a simple task with a tool like BlazeMeter. Stress tests examine how the system behaves under intense loads and how it recovers when going back to normal usage. Are the KPIs like throughput and response time the same as before spike in load?
- Similarly to load tests, stress testing has to be constantly reiterated.
- There isn’t enough time to implement the necessary improvements in time for the high traffic event.
- So how do you know when these changes affect the overall experience for users and customers, and ensure peak performance from all your systems?
- It will pass because the desired load is greater than the load according to the stress testing condition.
- The most significant difference that you should note here is that performance testing tests the system performance under varying loads, while stress testing tests the system performance for a sudden surge in loads.
Load testing must be executed during the application’s development phase. It must also be revisited at regular intervals throughout an app’s lifetime to ensure everything continues to work as it should. Ideally, load testing should form part of the Continuous Integration cycle so that it happens automatically. When load testing, you can also determine the behavior of the load.
Performance testing tools
Stress tests are designed to increase the number of simultaneous requests on a system beyond the upper limit of resource usage, and where performance is degraded – even to the point of complete failure. Where a load test will peak out in the number of simultaneous users, a stress test will continue to increase load on the system capacity until the resources are overloaded. This type of performance testing pushes https://globalcloudteam.com/ the system to a state of potential failure, to see how the system behaves, and whether it recovers successfully. Performance testing will help ensure your software meets the expected levels of service and provide a positive user experience. Performance testing will highlight improvements you should make to your applications relative to speed, stability, and scalability before they go into production.
A stress testing is one that goes beyond the normal expected usage of the system , with respect to load or volume. Both load and performance testing are used to analyze software by subjecting it to varying amounts of load while tracking the performance under different load conditions. Load testing is a complex procedure that includes assessing response times, resource utilization, and system throughput. Thanks to load testing, developers are able to fix issues before releasing a product to ensure it will not become a dealbreaker for end users. Briefly, both load testing and stress testing are under the large umbrella of performance testing, and though there are some similarities between them they are two very different tests.
Differences Between Performance, Load, and Stress Testing
The first failures highlighted during a stress test will be identical to those of the load test. Peak performance levels, number of servers required and app response times. Another possible positive outcome of stress testing is reducing operating costs. When it comes to cloud providers, they load test definition tend to charge for CPU and RAM usage or more powerful instances that cost more. For on-premise deployments, resource-intensive applications consume more electricity and produce more heat. So, identifying bottlenecks not only improves perceived user experience but also saves money and trees.
This configuration increases the load by 100 users every 2 minutes and stays at this level for 5 minutes. We have also included a recovery stage at the end, where the system is gradually decreasing the load to 0. If you’re facing internal or external challenges to handling high traffic events, there is another solution. It’s fast and easy to implement, doesn’t require significant optimization efforts, delivers a fair and reliable customer experience, and protects your site or app under any level of load. Even well-built load tests can sometimes suffer from their own perfection. This is because load tests typically follow very uniform patterns.

These metrics help to create SLAs for organizations and provide a guaranteed service level for users or customers. This testing is also designed to identify what is the number of users the system could handle before the performance will take a hit. Load tests are also helping companies in reducing the cost of failure and increasing customer satisfaction. There are plenty of QA testing tools for all the different testing types, thus, you can use a dedicated load testing tool such as JMeter.
Therefore, the main way to differentiate between these two types of testing is by focusing on their end goal. Response time stays the same, no matter how much load is applied or even decreases as a result of caching and just-in-time optimizations. Performance testing is a testing method used to determine the speed of a computer, network or devices. It’s simple to add custom validation and capture server responses to reuse later in the script.

With the help of this worksheet from TechRepublic Premium, you’ll be able to calculate … Load testing provides insights that help optimize the user experience of software even before it gets to the final consumers. This is crucial as user experience is one factor that may hamper the software’s adoption.
