  20. What is MBT? • Test automation: automates the test execution • Model Based Testing(MBT): automation of test design (automatic test generation using a model)

  21. MBT & Traditional Testing

  22. How we use MBT in Vestel?

  23. Usage Profile

  24. Before Creating the Model – State Table

  25. Before Creating the Model – State

  26. MaTeLo – Basic Model

  27. MaTeLo – Creating Test Cases Automatically

  28. VesTA Framework

  29. Experimental Results • Before MBT • During MBT work • Includes 100 real end users for getting usage profiles • Parsing log outs • Calculation of state transition probabilities based on usage profiles • Creating a usage model with MaTeLo • Generating 200 test cases automatically based on the model • Running these test cases on VesTA

  30. Experimental Results

  31. Model Based Testing Advantages • Usage profiles give an idea about most important modules, features and test scenarios • Clear, absolute and easily reproducible test scenarios • More available resources. With less resource to higher quality • Spend less calendar time in test process, get product out faster • More effective test sets resulting in a higher quality product • Fully measured & Reported process • Test suites with optimal coverage • Generated automatic tests can be run for different software versions as regression test • Less customer found defects
