Model Based Testing for Flexible and Predictable Test Coverage

About the Topic

Have you ever been given, in the course of testing, a specification change that required updating a large number of tests in your test suite? Did you ever wish that you could tell your test repository: “the main menu is gone, everything is accessed through a project navigation tree that works like this…”, then click on its magic Update button and Voilà, all the affected tests would be updated? Did you ever wish that you could tell your test cases to exercise the product to a very deep level for early verification, and then easily adjust them to a higher level for acceptance testing? If so, you may want to explore Model Based Testing.

Model Based Testing (MBT) refers to a set of techniques and tools to automate the creation of test cases from a model of the system under test. The model is typically a UML representation or a finite state machine that describes the behavior of a system (or part of a system) for which test cases will be created. The model can derive from models built to support code development, or created specifically to support testing. The overhead of model creation is offset by the reduced time spent in manual test writing or updating tests when requirements change.

A MBT tool processes the model and creates test cases based on it. The user can provide various parameters that affect the test creation. These parameters can, for example, specify the depth and breadth of test coverage that the output tests are required to provide. The output of such a tool can be used for manual execution, or can feed into a conventional test automation framework to produce test cases as scripts for automated execution.

Learning Objectives

MBT can
  • Foster a level of understanding of the requirements and specifications equal to or greater than is required for manual test design, thereby supporting early detection of design flaws
  • Bring the benefits of automation to an additional portion of the test cycle, freeing manual testers for more creative activities such as exploratory and usability testing
  • Provide testers with more effective tools to trace to requirements, justify risk-based decisions, and report on test coverage
  • Lower the cost of updating test suites for changing requirements
