ModelBasedTesting

Where does it fit?

Smartesting automatically generates complete test cases (Steps, Data, Expected Results)

for manual or automated execution.

To deliver our promise, the model must handle the 3 dimensions:

Business flow Business rules Data

A TESTING solution

Test Analyst

Requirements & Process Engineering

Test Design and Maintenance

Test Management & Execution

Traceability
