TestBot - Automated Test bench for Embedded Devices

TestBot is a state-of-the-art automated test bench used for testing the hardware, firmware, and application of any embedded electronic device - right from the stage of development to production level testing.


Customizable test bench for any embedded device

Testing is the most critical phase before the deployment of any product, as it ensures the quality of the offering. Improper (or) sloppy testing will cause product recalls and adversely affect the brand value of the vendor. Testing an embedded device is indeed a challenging task, as it depends upon high-level hardware & software. It also requires a lot of effort and thought process. Apart from this, external components such as mobile apps, cloud connections, electro-mechanical interfaces etc. also increase the level of complexity in testing.

At present, automatic test jigs have become popular, as they are capable of validating the DUT at a faster rate than that of the manual process. Embien’s TestBot is one such advanced automated test jig which not only helps qualify the device, but also supports the testing of external components. Its modular design makes it customizable for testing the hardware/software features of a variety of embedded products. Though TestBot is well suited for production stage testing, it can also be used during product development to identify issues earlier & enhance quality.

TestBot Features

Testing Methodologies

Supports various testing methodologies such as regression, long-run, positive, and negative case testing etc.

TestBot - Quality Assurance Tool

The demand for good quality, defect-free products has grown. This in turn, has made automated testing a necessity to keep up with the pressure and go-to-market needs. Automated testing offers test execution, efficiency, tasks, & coverage which manual testing fails to provide. Many tools are available to test software products (such as mobile and web app), whereas tools that aid in testing the hardware /physical interfaces are less. Switches, LEDs, Sensors etc. also require a mechanical setup for testing them manually.

By offering support for unhandled real-time simulation of hardware components & combining the pros of automated testing, Embien has made TestBot a complete package for all your testing needs. The generic hardware & the cross-platform tool used for testing the hardware/software of any embedded device is interconnected via serial interface, Ethernet, or USB. Multiple IOs & communication interfaces are made configurable, according to the test environment. TestBot enables users define the test cases & verification logic.Multiple test cases can be performed using automated test scripts & reports can be generated in the form of spreadsheets, text documents (or) XML format. It supports cloud level verification & uploads data to the cloud.
