Learn More About Load Testing Tools

What are Load Testing Tools?

Load testing tools are a subset of performance testing software, but load testing is one of the most important aspects of overall testing. There is much overlap between the two categories in terms of product coverage. Load testing is the simplest form of performance testing and is designed to test system behavior under expected loads.

This is different from stress testing, which is about overloading systems until they break to understand the outer performance limits. In contrast, load testing ensures a software application or physical network can handle user requests encountered under ordinary operating circumstances.

This activity is typically performed at, or close to, the end of the production cycle so that multi-user load simulations are more accurate. Individual components of an application might also be load tested as part of the development cycle, for example in agile development. However, this is generally referred to as functional testing.

Load testing enables users to evaluate application performance metrics, such as response times, resource-utilization levels, and throughput rates, under ‘normal’ circumstances.

Features & Capabilities

These are features that most load testing tools will have:

  • Multilocation load testing

  • Web application testing

  • API load testing

  • Database load testing

  • Mail load testing

  • Load test performance reporting

  • Load test plan/script customization

  • Support for load testing using a range of protocols (e.g. AngularJS, Flash, AJAX, HTML5, JavaScript, SOAP, JSON, WebAPI, WebSockets, etc.)

Load Testing Tool Comparison

When choosing a load testing tool there are a few factors you should consider. The first is the skill of your development team. There are a wide variety of open-source load testing tools businesses can use for free as long as they have the technical know-how. For businesses with fewer IT resources, it may make sense to go with a premium option that includes support instead.

Businesses should also consider what it is they are testing. Many load testing tools specialize for specific functions, such as API testing, database testing, or web application testing. Some tools are more generalized as well, so it is important to determine what your load testing needs are, and which tools can meet those needs.

Pricing Information

Many load testing tools are open-source and free to use.

Paid load testing tools are often combined with functional, performance, or stress testing tools, and are presented as a ‘testing platform. These platforms are typically priced on a monthly subscription basis, prices can range from $15 / mo to $175 / mo for more advanced plans. Prices for enterprise level solutions are available upon request.

Frequently Asked Questions

What businesses benefit most from load testing tools?

Load testing tools are most important for businesses that are releasing a new app or site, or are expecting an increase in traffic. A load testing tool will help ensure that an app or site can handle a sudden influx in traffic.

Are there any free or open source load testing tools?

There are several completely free load testing tools, though they tend to be a little harder to implement as they do not have dedicated support. This makes open source load testing tools a good choice for businesses with an experienced development team for implementation.

How are load testing tools different than stress testing tools?

Stress testing tools are designed to push a system to its outer limit so that you know the most extreme circumstances the system can perform at. Load testing tools are used to see how the system will perform at different levels of use. Both tools are important for testing a system at the end of the production cycle.
