Model Based Testing Training Workshop, Model Based Testing (MBT) Training Workshop

Model Based Testing Training Workshop is a 3-day hands-on project-based training course. Model based Testing course covers the formalized application of modeling to support systems testing, verification, and validation activities.

The application of model-based testing for designing and optionally executing testing, verification and validation artifacts is called model based testing (MBT). These models can be used to represent the desired behavior of a system under test (SUT), or to represent testing strategies and a test environment.

 

MBT has become a popular modality for organizations because it helps create better system and software  quality by getting teams thinking about the models applied to testing. MBT also reduces test suit maintenance and allows for flexibility to generate many tests using different algorithms such as smoke, regression, integration, end-to-end and targeted testing for new or modified features.

These models are used to generate automatic test cases, and they represent how we expect the system to behave under test. The usual steps go something like this:

  • A model is created to capture the behavior of the system being tested.
  • An MBT tool is used that interprets this behavior to develop manual testing scripts.
  • The MBT tool generates scripts for automated testing.

Who Should Attend?
Model Based Testing is designed for test engineers, analysts, project managers and anyone else involved in test and evaluation, systems engineering and acquisition, modeling, simulation, DoE, and O&M.

Participants will learn how model-based testing and MBSE can assist in defining system capabilities and limitations, improving the system performance and optimizing system use and sustainment in operations. T&E enables the engineers and PMs to learn about limitations (technical or operational), Critical Operational Issues (COI), of the system under development so that they can be resolved prior to production and deployment.

Learn how model-based testing and MBSE is used as a process to compare complex system or components against requirements and specifications through testing. Developmental test and evaluation (T&E) is used as an engineering tool to reduce risk throughout the acquisition cycle. Operational test and evaluation (OT&E) are used as actual or simulated environment to evaluate systems under realistic operational conditions.

There are numerous models available and it describes different aspects of the system behavior used in testing, verification , validation and integration act ivies and certification. Examples of the model are:

  • Data Flow
  • Control Flow
  • Dependency Graphs
  • Decision Tables
  • State transition machine

For most organizations, the move toward models holds promise, but it also introduces new challenges that should be addressed before realizing the full benefits of MBT.
