What is Model-based test automation in TOSCA ?

Model-based testing is a technique in which a model of the software system is used to generate test cases. The model is typically a visual representation of the system’s UI components. Each model consists of functional actions that can be performed on the system or application. Test data is added separately to test different scenarios. The advantage of this approach is that it allows for testing a variety of scenarios without hard-coding test data or business logic into the models. The model is used to automatically generate test cases that cover various scenarios and test conditions, making it useful for complex scenarios that rely on several integrated applications and technologies. The models are code-free and highly reusable.

Working Steps: 

Simply scan your application’s user interface or API to create the models. Drag and drop the models into place to create your test cases. Add your test data and the functional actions you want enacted on those screen elements. When done, run your test case.
