testHarmony LE Exerciser

The testHarmony LE Exerciser is a highly flexible test solution designed to provide pre-comliance, 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 Bluetooth LE 4.0, 4.1, 4.2, 5, 5.1 and 5.2 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"
