Model-Based Testing – QA Valley

Model Based Testing

QA Valley utilizes Model-Based Testing techniques to generate test cases based on models of behavior that software must exhibit, and execute the generated test cases to validate that the behavior do conform to the underlining models.

A Model is an abstract partial presentation of the system under test (SUT). Models are used to represent the desired behaviour of an application or to represent testing strategies and a test environment.A lightweight model is developed that impersonates the system under test and derives test cases that describe the functional aspects of the SUT. The predictions made by the model is compared with the run time behaviour of the SUT. Behaviour of the application is measured in terms of input sequences, actions, conditions, output and flow of data from input to output.

A modelof the system under test (SUT) is first developed and various inputs and expected outputsare determined. Test cases are executed, and the results returned are compared with the expected output. Based on the output decision is made on the action on the model.There are aspects of models which describe different system behaviour. Models depicting Data Flow, Control Flow, Dependency, Decision Tables, Finite State Machines, and State Charts are some of them. Two types of Modelsare on-the-fly where test suites are generated during test execution and offline where test suites are generated prior to test execution.

Automation Tools used for model-based testing are fMBT, Tricentis Tosca, Modbat and 4Test which allows QA Valley testing team to improve test coverage and reduce costs. QA Valley adopts the latest framework and tools to simplify the testing process and enhance accuracy and with the assistance of competent testers and tools, QA Valley produces software applications that are compatible with the requirements of testing. Engagement Models by QA Valley are tailored to reflect the various needs like maturity, involvement,technology and other factors for victorious project delivery. Customers can choose services basedon time, cost, size needs, and other criteria.
