What TESSY does
TESSY automates unit and integration testing for embedded C and C++ software. It supports engineering teams throughout the test workflow, from project setup and test design to execution, result analysis and reporting.
Instead of managing test cases, coverage data, requirements and reports across disconnected tools, TESSY brings the full test process together in one structured environment. This helps teams reduce manual effort, improve repeatability and strengthen certification readiness.
- Automated unit and integration testing for C and C++ code
- Regression testing across software versions
- Requirements management and traceability
- Coverage measurement and review
- Test result analysis and reporting
- Support for different target systems and toolchains
General Features
Structured test workflow
Guides teams from project setup and test design to execution, analysis and reporting.
Regression testing
Re-run tests efficiently as embedded software changes across versions and releases.
Requirements traceability
Link requirements, test cases and validation results for clear coverage and impact analysis.
Coverage measurement
Measure and review test coverage to identify untested or insufficiently validated code.
Automated reporting
Generate structured reports for test plans, test results, coverage and certification documentation.
Target system support
Supports testing on different target systems and integrates with existing development environments.
Why TESSY
Embedded software testing can quickly become time-consuming when test cases, requirements, coverage and reports are managed separately. TESSY enables a more controlled approach:
From manual effort
to automated test execution
to automated test execution
From scattered data
to one structured workflow
to one structured workflow
From limited visibility
to traceable test results
to traceable test results
This results in:
Reduced test effort

When to use TESSY
TESSY is most valuable in environments where:
Unit and integration testing must be standardized
Regression testing needs to be efficient and repeatable
Requirements traceability is required
Coverage and reporting support certification
Typical domains include automotive, medical, rail, industrial automation and other embedded systems where quality, repeatability and certification support matter.
