"Load testing support for APIs is limited in LoadRunner"
HP LoadRunner’s support for test creation through discovery and recording of REST APIs is limited, tooling for API formats and protocols like Swagger is limited.
LoadUI Pro not only supports the latest API protocols like IoT and Web-sockets but also has out of the box support for popular API specifications and formats like JSON, Swagger and RAML.
"It’s hard to load test across the API ecosystem"
APIs do not work in silos, they are designed on one tool, tested on other and hosted and managed on platforms across the API ecosystem. HP LoadRunner has no integrations with the popular API platforms.
LoadUI Pro has integrations with API platforms like SwaggerHub and Amazon API gateway, this enables seamless pull, load test and deploy from right inside the tool.
"Creating load tests with LoadRunner is complicated and slow"
LoadRunner has roots in UI testing and is script heavy, anytime during creating tests users need to create and modify scripts.
With LoadUI Pro a sophisticated load test can be created with point and click, also information about the load tests can be retrieved by just a glance at the application.
"Testing my APIs with LoadRunner is expensive and time consuming"
LoadRunner has expensive renewal rates, software license fees. Getting teams trained on LoadRunner takes time. Hiring is expensive as finding a scripting expert is hard.
LoadUI Pro is cheap to own and operate and has a simple licensing structure. It’s built on the SoapUI core to which millions of developers and testers are already familiar; hence users get started quickly with minimal training.
