Model Based Testing

A new paradigm for manual and automated functional testing.

 

Testing is an essential, but time and resource consuming activity in the software development process. Generating a short, but effective test suite usually needs a lot of manual work and expert knowledge. In a model-based process, among other sub-tasks, test construction and test execution can be automated.

What is Model Based Testing?

Model based testing is a black box testing technique where run time behavior of a software under test is checked against predictions made by a formal specification or model. In other means, it describes how system behaves in response to an action ( determined by a model). Supply action ,and see, if the system responds as per the expectation.

Testers construct mental models anyway during their testing. Those mental models can be transformed to models on paper. This helps testers to achieve readability and re-usability.

What are the advantages of Model based Testing?

• Easy test case/suite maintenance
• Reduction in Cost
• Improved Test Coverage
• Can run different tests on n number  of machines
• Early defect detection
• Increase in defect count
• Time savings
• Improved tester job satisfaction
