Software performance testing tools, frequently shortened to “perf testing tools” by industry specialists, are a critical part of a comprehensive approach to software testing. These tools help testers verify how their software responds to the load and stress they will face in the real world by simulating what happens when people use your product.
There are many excellent performance testing tools on the market. Picking the right one for the job isn’t easy, but we’re here to help.
In this article, we’ll explore:
- What performance testing software is and why it’s important
- What qualities to look for in a performance testing tool
- Top 10 best performance testing tools in software testing today.
What is performance testing?
Performance testing is a software testing technique that aims to determine whether an app can withstand the rigors of daily use. When developers write and execute code, they run tests to see if the app functions as intended. That process is referred to as functional testing.
However, non-functional is equally important to a well-running product. This kind of testing verifies other aspects of the software, such as stability, usability, and, most relevant to this article, application performance.
In Ian Molyneaux’s landmark book, The Art of Application Performance Testing, the author outlines two key ways to measure software quality: service-oriented and efficiency-oriented
Molyneux goes on to explain that service-oriented indicators are availability and response time. In other words, it asks the question of whether the application provides a reliable service to users.
Likewise, he refers to efficiency-oriented indicators as throughput and utilization. For Molyneux, these indicators show “how well the application makes use of the application landscape.”
Let’s break the concept down in the table below.
| Service-oriented indicators | |
| Availability | Downtime costs money.
What percentage of the time is your application running? What scenarios cause it to become unavailable? |
| Response time | When a user performs an action, how long does it take the application to respond?
What scenarios cause the response time to grow? |
| Efficiency-oriented indicators | |
| Throughput | How many distinct actions or events can your application manage in a specific time frame?
How many users can your web application serve before performance degrades? |
| Utilization | Each resource has a theoretical capacity. Utilization measures the percentage of use of each resource.
How much CPU, Memory, Disk I/O, or Network bandwidth does your application use? What happens to the application when upper bounds are reached? |
While performance testing is a wide-ranging and complex subject, the above should give enough grounding in the concept to establish what to look for in free and enterprise performance testing tools. For a deep dive into all things performance testing, read our comprehensive article, What is performance testing?
How do we evaluate the best performance testing tools?
The best way to evaluate performance testing tools is to establish a set of criteria to measure each tool against. Here are the ten factors to consider when deciding on the right tool for your project.
#1. Cost
Everyone is working to some sort of budget. One of the most important criteria for evaluating paid or enterprise performance testing tools is the cost. In particular, you need to know whether it can bring a return on investment, and that’s far more likely to happen if your base costs are reasonable.
With costs in mind, we will also evaluate and share some free performance testing tools on our list so teams working under financial constraints don’t miss out.
#2. Realistic user simulation
A good performance testing tool should be able to mimic huge volumes of users or data or unstable Wi-Fi connections. It should also be able to show how your app will run on different devices or platforms.
#3. Protocol support
Can a testing tool support a variety of protocols? You need this compatibility and flexibility to adjust to different project requirements and test interoperability.
#4. Technology support
Similar to the point above, can your perf testing tools handle APIs or various front-end and back-end technologies?
#5. No-code capabilities
Can your tool build performance test cases using a drag-and-drop or visual interface or even Generative AI prompts? It’s a huge time saver and something you can’t afford to leave off your list of criteria.
#6. Scripting capabilities
While no-code tools are great for saving time and supporting non-technical teams, there are scenarios where you need to get into the weeds. Can your performance testing tool give you the flexibility of both approaches?
#7. Reporting and analytics
Good performance testing software should also offer granular metrics highlighting bottlenecks and failures. These features are not just about giving you the data you need to fix problems but also about having visualizations that you can present to stakeholders or investors.
#8. Integration
Integration is important. For example, seamlessly connecting to your CI/CD pipeline tools like Jenkins, Bamboo, or GitLab means that you can automate performance testing and ensure thorough coverage.
#9. Automation
If you want efficient, repeatable, and scalable performance testing, automation is a big consideration.
#10. Support
Finally, good vendor support is essential if you want to get the most from software performance testing tools. Of course, that support can come in many forms, such as technical support, an active user community, training, documentation, tutorials, how-to articles, and related content.
OK, so now that we’ve established what criteria to look out for, it’s time to share our performance testing tools list.
The top 10 performance testing tools in software testing
As you can see from the benchmarks above, the best performance testing tools in software testing have a few things in common. So, considering these strict criteria, it’s time to run the rule over the contenders to find the best tools in the performance testing space.
