This Gartner® research breaks down what’s changing in API testing, why GenAI is reshaping quality practices, and how teams can build a complete, reliable API testing lifecycle that scales.

In this report, you’ll learn:

• Why APIs introduce unique risks and why relying on inconsistent, ad hoc testing slows delivery.
• How the diverse API testing tool landscape is evolving, including the shift away from tools like Postman for cost and cloud-dependency reasons.
• How GenAI is transforming API testing through auto-generated scenarios and self-healing scripts — along with the risks of hallucinations, bias, and false confidence.
• What to look for when selecting an API testing platform that supports all API types, integrates into your toolchain, and scales without patchwork tooling.

Get ahead of accelerating API complexity. Whether your teams are building AI-enabled apps, operating in hybrid environments, or modernizing legacy systems, this research shows how to unify your API testing strategy, increase coverage, and ship safer software.
