testHarmony LE Exerciser

Harmony LE Tester

The testHarmony LE Exerciser is a highly flexible test solution designed to provide pre-compliance, debugging, regression and robustness testing for chipset vendors and product manufacturers during the development cycle and post release. The tester supports test case package licenses based on Bluetooth feature group functionality, and are available either individually or as a complete package.

testHarmony supports a subset of test cases that enable the user to change specific test case parameters to test above and beyond the Bluetooth SIG LE specification. With the purchase of testHarmony and at least one test case package the user will also get access to a set of custom test cases that are not part of the specification.

testHarmony supports iterative testing of individual test cases and full automated test runs. Results from individual test runs can be exported to PDF and Excel format, and multiple test runs from the same project can be exported to a summary report for comparison.

testHarmony is an integrated software/hardware test platform for Bluetooth protocol testing that provides:

  • Test Manager
  • Upper Tester
  • Lower Tester
The testHarmony LE Exerciser provides test scripts to execute Bluetooth LE controller Link Layer and HCI test cases, covering all adopted Bluetooth LE core specifications.

Test Manager
The Test Manager is responsible for test execution and results logging, and running test scripts. Test execution is automated, which allows the system to be integrated into automated regression test systems where no operator intervention is required in order to execute a test suite and parse the pass/fail results. Automated error recovery of the IUT from failures during testing prevents a cascade of failures due to a previous test, limiting failures to just the test that caused the IUT to fail.

Upper Tester
The Upper Tester interfaces to the IUT (Implementation Under Test) via HCI UART.

Lower Tester
The Lower Tester interfaces to the IUT via RF over the air and RF conducted.

  • HCI and over-the-air capture files via X240 Protocol analyzer
  • Complete log of test case validations and verdicts
Features and Benefits
  • Provides regression testing of Bluetooth low energy HCI and Link Layer implementations
  • Export test results for individual runs or across multiple runs within the same test project for detailed comparison
  • Flexible test configuration supports multiple IUTs
  • Summarizes and pinpoints root cause of a fail or inconclusive result
  • Allows for integration into "no operator required" automated test regression systems
  • User can customize test runs based on individual features or full test runss
  • Test Manager, Upper Tester and Lower Tester in one small, portable platform
  • Automated error recovery of IUT from failures during testing prevents cascade of failures and "false-negatives"
