The term load testing is used in different ways in the professional software testing community. For example, a word processor or graphics editor can be forced to read an extremely large document; or a financial package can be forced to generate a report based on several years’ worth of data. The most accurate load testing simulates actual use, as opposed to testing using theoretical or analytical modeling. Load testing helps developers identify issues like system lag, slow page load times, or crashes when different levels of traffic are accessing the application during production rather than post-launch. A load testing example would be a tax preparation company evaluating their web application load performance prior to peak income tax filing season and the traffic spikes it causes.

Load testing determines if the system can handle a certain number of users or transactions per second. However, load testing is the best approach for ensuring that a software application or physical network can withstand the user requests and actions it is likely to experience under normal circumstances. Another possible positive outcome of stress testing is reducing operating costs. When it comes to cloud providers, they 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.

Test case development

The load testing practice is designed and used to evaluate how a software system behaves during normal and high loads to determine if it can handle high loads during high demand periods. BlazeMeter is a continuous testing platform that enables developers and testers to test the performance of their web and mobile applications under different user loads. It provides a comprehensive range of testing capabilities, including load testing, stress testing, and endurance testing that is open-source compatible. BlazeMeter also supports functional testing and API testing, and provides capabilities like mocking and test data. Team members conducting load tests will benefit greatly from prior experience.

We look forward to learning more and consulting you about your product idea or helping you find the right solution for an existing project. Therefore, the main way to differentiate between these two types of testing is by focusing on their end goal. Capturing client side changes that don’t interact with server can be extremely tedious and time consuming. Find complete product documentation to learn how to get started and use the product.

Spike Tests

If you’re an ecommerce site, you’ll want to be prepared for large numbers of customers at certain times, such as on Black Friday. A use case we’ve been involved with recently is load testing of the various systems hospitals rely on to roll out COVID-19 vaccines. The point is, whatever your business or are of concern, load testing should be a consideration. When software doesn’t work properly, the effects range from the merely inconvenient to the potentially catastrophic.

• Load Testing is a type of Performance Testing that determines the performance of a system, software product, or software application under real-life based load conditions.
• Just because your application will pass a functional test, this does not mean that it can perform the same under a load.
• However, all load test plans attempt to simulate system performance across a range of anticipated peak workflows and volumes.
• As a result, load testing is a superior way to investigate, analyse, and fix errors before they occur in real-time.
• While this is an efficient way to run a load test, you may miss out on some of the insights possible when testing at the GUI level.
• You can then tweak the programs to make inevitable failures more graceful.

While this is an efficient way to run a load test, you may miss out on some of the insights possible when testing at the GUI level. Remember, GUI virtual users are much more resource-intensive, so this should factor into your plan. Adopting this method brings us a step closer to ensuring that our application is equipped to meet real-world demands.

FEMA noted that, for people who were in the middle of a phone call at the time of the alert, the message and tone would be delayed until they hung up. Wireless providers that participate in the integrated public system then dispatch alerts from cell towers to compatible phones in geo-targeted areas. “When it comes to evaluating the results of the alerting tests, the FCC is collecting information both from EAS participants and participants in WEA,” a spokesperson for the FCC said Tuesday. “So for all EAS participants, and that includes broadcasters, cable companies, satellite TVs, and so forth, they’re required to file information with the FCC about how the test went for them.” Wednesday’s test was conducted to evaluate the technological capabilities of the national alert system to reach and inform as many people as possible in case of a widespread emergency.

Assume we want to test an online shopping application to evaluate how quickly it responds to each user click, i.e. Launch URL, response time, Log in to the application and take notes on things like selecting a product, adding it to your basket, pay for it, and logging out. However, manual load testing is not recommended because the application is not tested for a lower load.

Tune the Transient Response

Scalability tests measure how an application can scale certain performance test attributes up or down. When running a scalability test based on a factor like the number of user requests, testers can determine the performance of an application when the user requests scale up or down. While load testing and stress testing are two of the most popular performance testing types, they are far from the only performance testing options available. The following figure shows an example of a performance testing report on BlazeMeter.

Many load-testing tools, such as Apache JMeter, BlazeMeter, Locust, LoadNinja, and Gatling, have been introduced to automate and streamline the load-testing process. Load tests uncover application performance issues before the features are deployed to production, delivering users the most optimized versions of the application. Error rates and response times can be significantly reduced if issues related to them are identified and fixed beforehand. Thus, users can enjoy the features of your application without any performance issues. Load testing can be carried out in an environment that stimulates the production environment or in the production environment itself under defined settings.

Load testing

If we have a large budget, we can use commercial solutions such as LoadRunner, but if we don’t, we can use open source tools like JMeter, etc. So, instead of utilizing a tool, we can now physically load the application with five physical users from various workstations to test the application load for five users. In this case, it is preferable to perform a manual load test rather than purchasing a product and configuring an environment for it.

These queries can significantly slow down the application, negatively impacting user experience. To address this issue, Service Level Agreements (SLAs) are established for critical transactions, specifying certain performance criteria that need to be met. Load tests help determine if the application violates what is load test these predefined performance values when subjected to different loads. There are a lot of load testing tools you’ll find in the market, but not all of them are the perfect fit to help your business succeed. Examples of these load tester software and tools are WebLOAD, LoadView, and Loadrunner.

After completion of the test, a performance tester verifies the result against the defined load test NFRs.

Load tests are a good way to test a system, assess potential risks in advance, and possibly improve it. However, it’s important to consider a few things before conducting a load test.
