Load Testing Explained: Process, Top Tools & Benefits

Printer load tests involve sending increasing numbers of jobs to the printer queue. If you’ve conducted previous tests, use the data to create a performance baseline for the upcoming test. Even those with professional experience can feel confused about the following types of software testing services. The organization can develop performance goals by analyzing traffic during both average and peak hours. Next, we need to select how many users we want performing these activities at a time.

One such area is performance testing, which refers to the broad set of measures taken to determine whether software meets various speed, stability, and scalability requirements. Throughput refers to the number of transactions processed within a unit of time. A high throughput indicates that the application is performing well under high load. Load testing helps determine the maximum throughput the system can achieve and identifies potential bottlenecks that may limit it. Then, the performance team gathers the automatically generated results through the load testing tool and presents their observations, recommendations, and decisions to the engineering team for further analysis.

Types of Testing

Many systems allow for spinning up multiple scenarios per machine and even help you spin up multiple machines in the cloud. Initially, determine the goal of the application, identify your audience, and the size of the audience. Identify the ideal average number of users that might simultaneously use the product and then identify the maximum number of simultaneous users during a heavy stress event. The definition of load testing a website is generating a specified amount of load on a website. Typically, tests are performed in a fashion that imitates real users visiting the website. More advanced tests may perform a series of steps on the website, such as clicking on key elements, buttons and fields and navigating through the site.

Note that only layers with learnable parameters (convolutional layers,
linear layers, etc.) and registered buffers (batchnorm’s running_mean)
have entries in the model’s state_dict. Optimizer
objects (torch.optim) also have a state_dict, which contains
information about the optimizer’s state, as well as the hyperparameters
used. This document provides solutions to a variety of use cases regarding the
saving and loading of PyTorch models.

Access to multiple devices helps you predict and handle issues before your product reaches production. BrowserStack Automate provides access to an array of web browsers and OS for you to test your applications. The Load tests also assist in planning capacity to handle peak load conditions, enhancing user experience by optimizing response times. By conducting thorough load testing, you can mitigate risks, optimize costs, and ensure that your system remains stable even during a peak load condition.

There is no end to the amount and variety of tools and platforms in the market today, with a variety of features. From platforms leveraging open-source only tools like BlazeMeter, to headless browser only solutions like Phantom JS, or platforms offering multiple user simulations, like LoadView. Choose a load testing what is load testing platform best suited for your needs and requirements. When conducting a load test, it is crucial to have a dedicated testing environment that mirrors the production environment as closely as possible. In cases where third-party applications are involved, these can be replaced with stubs for testing purposes.

Saving & Loading Model for Inference¶

Load testing is part of performance testing and there are subtle differences between them. Apart from the above load testing types, there are several more that might be custom to a system environment and required to test the stability of the system. Load testing allows developers to make enhancements before deploying the code to production, eliminating future issues. Spokespeople from FEMA and the FCC said both agencies are confident the emergency alert system works as intended for television and radio broadcasts as well as mobile phones.

The longer someone takes a particular HIV therapy, the less likely it is to stop working. Almost everyone who goes on to a second or third regimen reduces their viral load to an undetectable level. If HIV is undetectable in blood, it’s likely to be undetectable elsewhere.

What is load testing?

The load testing tool calculates this by summing the total response times and dividing it by the requests count. The lower the response time, the better your system handles a high load. Load testing is a type of performance testing that assesses an application or system’s behavior under a specific expected load. This involves simulating a large number of concurrent users or operations concurrently accessing or interacting with the system, aiming to uncover performance bottlenecks, scalability issues, and other potential problems. Single-page applications (SPAs), sometimes called single-page interface (SPIs), can be trickier to test in terms of measuring KPIs because the page does not necessarily reload each time the user performs an action.

The most common way to create a load scenario is by combining scripting with recorded user activity. Each scenario will include measurements, transactions, and validation points. Build or host a website, launch a server, or store your data and more with our most popular products for less. Next, establish benchmarks for each scenario by simply running and recording the results of each individual test under ideal conditions.

The performance testing life cycle describes the process of arriving at one or more of a series of tests that should be performed for measuring metrics of an application over time. Smoke testing performs low-level background tests, ensuring the system can handle the bare minimum requirements. Smoke testing is often carried out during the initial stages of software development. By identifying errors and defects earlier within the cycle, teams can release the software in a more efficient manner and avoid costly (and time-consuming) last-minute defects.

  • Load tests seek to discover how the system performs under normal conditions.
  • Load tests are a good way to test a system, assess potential risks in advance, and possibly improve it.
  • The Load tests also assist in planning capacity to handle peak load conditions, enhancing user experience by optimizing response times.
  • From there, a load balancer distributes the user requests across various web servers.
  • Load testing in Java can also refer to several different types of tests, as Java can natively run in many different environments on Java virtual machines.

There are many popular client-side and client-server side JavaScript frameworks that are used to create SPAs. Frameworks like Angular, Next.js, React, Vue, and many others can all be used to develop SPAs. Single-page applications “fit” on a single page and update dynamically, rather than load a new page each time.


If the system successfully responds to all requests within the required time, the system has successfully passed a capacity test. These performance metrics are necessary for assisting with capacity planning so you can meet the demands of your customers and clients. Poor performing sites and applications impact conversions, and ultimately, revenue. Every tool mentioned above has unique strengths and is more suitable for certain load testing scenarios. The choice of tool will depend on your specific requirements and your team’s expertise.
