Rapidly Automate IoT App Testing by Simulating and Virtualizing Devices at Scale

Doppelio HP


Create data twins (Doppels) of any device in our system. All you need is the device datasheet or some recorded data.


Simulate any number of device behaviour patterns and test any amount of load, on-demand. Anytime and anywhere.



Automate the testing across the lifecycle  from Unit Testing to Post Release troubleshooting.

IoT testing made easy with Doppelio IoT Test automation platform

Any scenario. Any environment. Any device. Any scale.

Doppelio lets you Virtualize physical devices and Simulate their data behaviour in a few clicks. These simulated devices or Doppels and test scenarios will help you test your IoT Applications comprehensively while reducing dependence on physical devices. Go beyond testing limited lab devices to a full system of things and to a scale of a million devices.

Our Thoughts and Perspective on IoT Testing

Why “all is well” in load testing, but not in production?

Why “all is well” in load testing, but not in production?

Are you load testing exhaustively enough?System performance under real life load is critical to the success of any large-scale solution. We do a fair amount of load testing and performance benchmarking, but one common situation is when all our load tests pass but post...
