Features

What TERSA can do

TERSA combines requirements, signal information, reusable test components, and AI-powered reasoning into a structured test generation pipeline.

Dependency analysis

Automatic detection of dependencies between requirements — directly from requirement text and signal data. Includes interactive dependency matrix visualization.

Placeholder Completion

Project-specific signals, parameters, thresholds, and evaluation logic are automatically inserted into the test structures.

Test Sequence Selection

TERSA selects suitable test sequence templates and reusable building blocks — depending on the requirements context.

Explainable AI

Every suggestion is justified: TERSA shows why a test sequence was chosen, which signals are used, and how the test structure is tied to the requirement.

From complex requirements to structured test specifications

TERSA integrates into the early phases of the system test process. Based on requirements and project-specific input data, the tool supports the creation of test specifications that describe:

  • What needs to be tested

  • Under which conditions it needs to be tested

  • Which input signals and parameters are relevant

  • Which result is expected

  • How the generated test case can be refined, checked, and implemented

Thus, the test specification becomes a clear blueprint for concrete test cases — independent of the final technical implementation or execution environment.

How TERSA works

TERSA combines requirements, signal information, reusable test building blocks, and AI-assisted reasoning into a structured test generation pipeline.

The result: a controlled, AI-assisted workflow — fast where automation helps; transparent where expert judgment is required.
