The true measure of an application isn’t how well it handles a slow, ordinary day, but how it performs under pressure. Ensuring that your solution can tolerate stress and still succeed is important to creating an application or hardware device with staying power.

In this article, I’ve done some digging and found the best stress testing software available on the market today. Below you’ll find the details of what each platform has to offer, some information on my selection process, and the answers to the most common questions about stress testing software.

What is Stress Testing Software?

Stress testing software helps organizations verify the stability of their applications and hardware under extremely heavy load conditions. IT teams can gain insights into their system’s robustness and error handling capabilities to prevent crashes during critical business operations.

Different types of stress testing software exist, covering a range of operating systems and hardware components, including CPU cores, graphics cards, and RAM. Testers have the ability to simulate thousands, or even millions, of users to exercise the resources on their network beyond normal operating points.

Core Temp

Best for real-time monitoring of processing core temperature

Core Temp is a compact Windows gadget that monitors processor temperature and load, frequency, and VID settings. The tool can provide temperature readings for the individual cores of every processor within a system during stress testing. As your system’s workload changes, Core Temp displays temperature fluctuations in real-time.

Temperature readings are collected directly from a digital thermal sensor located near the hottest part of each processing core in your system. Digital thermal sensors don’t rely on external circuits located on the motherboard to report temperature, resulting in highly accurate readings.

Core Temp supports Intel, AMD, and VIA processors and is also motherboard agnostic. Developers can also leverage plug-ins, like Core Temp MC, which can display the status of a processor directly from the Windows Media Center UI.

Core Temp is free for all users, with apps available for Android and Windows devices to monitor your system on the go.

LoadTracer

Best for test parameterization

LoadTracer is a free GUI-based tool for load, stress, and performance testing of web applications. The software was developed in C language, making it a lightweight tool that won’t put an extra burden on your operating system’s performance. Testers can generate thousands of virtual users to execute simulations and follow up with LoadTracer’s analyzer tool to assess their system’s stability and performance.

With LoadTracer’s parameterization functionality, testers can generate different attributes for each virtual user. It makes load tests more realistic since real-world users behave as individuals rather than clones of each other. Duplicating tests across different platforms is also easier. Instead of re-scripting a test for each new environment, testers can simply change one parameter value.

LoadTracer is proxy-based, enabling testers to utilize the tool on any browser.

LoadTracer is free to use.

4. Systemic Stress Testing: Exercises multiple systems running on the same server to identify applications that may be data blocking others. 
5. Exploratory Stress Testing: Utilizes unusual parameters to find defects in unexpected scenarios, such as large numbers of users logging into a system at one time.

How to Perform Stress Testing?

The process of stress testing can be broken down into 6 steps:

1. Determine Your Testing Environment: What tools do you have available to perform the test? The stress testing software on this list are all excellent options.
2. Establish Your Performance Acceptance Criteria: Decide what metrics your test needs to pass in order to be considered successful.
3. Test Design: The design of your test scenarios will be dependent on the goals of your test.
4. Prep Your Environment: The best stress testing software can help you prepare the test environment in accordance with your test design.
5. Test Execution: Perform your tests and collect results via your stress testing software.
6. Results Analysis: Take a look at the data gleaned from your tests. Were there any issues that need to be addressed?

What is the Difference Between Load Testing and Stress Testing?

Load testing is the process of testing a system’s behavior under an expected load. Stress testing, on the other hand, tests the system to its upper limit, beyond the application’s known maximum.
