The MBTsuite provides a better approach to designing and updating software tests.
The MBTsuite allows you to work with flow chart models, where test cases are automatically generated and logged.
How does it work?
First, you create the flow chart model, also known as "test model". From this model, you generate required test cases, which you can then use for manual or automated execution as needed.
If requirements change, you can easily update your pre-existing test model and automatically generate updated test cases.

How it works
Creating the test model
First, the test designer creates a flow chart describing the different actions and alternatives. This model is easier to create, understand and change than a textual test specification.
After starting up, there are 2 login alternatives: via chip card or via PIN. When the user has logged in, he/she can select either button A or button B, which in turn lights up the respective lamps A or B. The user can select these buttons several times.
The graphic below illustrates a test model of the system. Rather than writing 50-100 lines of plain text in a test specification, the test model provides all the information at one glance.
Generating the test cases automatically
After creating the test model, you can generate test cases either for manual or automated execution.
MBTsuite will run a detailed analysis on the model. All you have to do is decide which strategy or filter you prefer. You can even generate test cases exclusively relevant to a specific set of requirements.
The outcome can be a test specification for manual execution or a source code for automated execution. It’s your choice.
Executing the tests
Now after creating the test cases you are ready for execution.
Depending on the type of test cases you have selected this will be done either manually or automatically.
Updating the model
When requirements change, tests need updating accordingly. With MBTsuite you don’t need to re-examine the entire test specification or test automation code to make adaptations to the test cases. You only have to update your model at specific places and the updated test cases are generated automatically.
You want to add a fingerprint sensor to the login options. Without MBTsuite, all test cases have to be re-examined and adapted. However, with MBTsuite you can extend your flow chart with an additional action for the fingerprint sensor. The test cases are re-generated automatically - ready for execution.
