Top 18 AI Testing Tools in 2024

The impact of AI tools on software development is starting to make itself felt. As the productivity of developers increases, so does the necessity for software testing. Luckily, AI is also seeing increasing adoption in testing, enabling dev teams to ensure robust and secure software despite increasing output. In this in-depth guide, we will explore the top 18 AI testing tools in 2024 that have the potential to take your testing processes to the next level.


Why We Need AI Testing Tools

Fast-paced release cycles, increasing third-party dependencies and growing API reliance have presented software testing with some serious challenges these past years. As a result, 45% of software is being released without appropriate security checks. This trend is manifesting itself in roughly 50% of organizations reporting at least one security incident over a period of 12 months (recorded in 2022).  Now, as AI coding assistants have entered the chat, these numbers are likely to worsen, as research findings suggest that such coding tools produce equally insecure or more insecure results than humans. Even if AI coding assistants become more secure over time, the sheer increase in output will induce calls for more scalable testing solutions. Luckily, AI-powered software testing tools can help to ensure that testing keeps pace with these developments.

What Are the Benefits of AI Testing Tools?

To hold external threats at bay and meet modern quality and security standards, AI testing tools are becoming indispensable. Let's explore some of the advantages that are driving this shift:


More code requires more testing. As coding assistants such as GitHub Copilot are enabling developers to multiply their output, traditional testing methods are increasingly falling behind as they require too much manual effort to address such quantities of code. AI testing tools, however, excel at performing tests on a massive scale. This scalability extends to testing various devices, platforms, and environments, ensuring broad coverage that enables reliable bug and vulnerability detection despite large amounts of code.

Continuous Improvement

AI testing tools running on genetic algorithms can be set up to learn and enhance over time. By learning about the software under test on the go, these tools can start with a blank slate and iteratively improve test inputs based on the application's behavior during runtime. This allows such tools to get better with every test run, leading to findings beyond the reach of most traditional testing tools.

Surpassing Manual Testing Limitations

While a traditional unit test tests one case at a time, AI tools can enhance it to test the same function or API with hundreds of thousands of unexpected or invalid inputs. This allows developers to automatically find bugs and vulnerabilities in places they never even would have thought to look.

Increased Test Coverage

Self-learning algorithms can be leveraged to continuously increase test coverage with each new input. While traditional dynamic testing methods (and hackers) treat the application under test as a black box, this white-box approach gives dev teams full visibility into the internal workings of the software. Increasing code coverage allows dev teams to gain a leg up over attackers, as they can use the source code to their advantage. Additionally, having access to the source code simplifies debugging, as findings can easily be traced back to the erroneous section of the source code.
