Model-Based STLC

 

1. Software Testing Life Cycle (STLC):

   • STLC is a systematic process for planning, creating, and executing tests on a software application. It involves several phases, each with its specific objectives and deliverables. The common phases in STLC include Requirements Analysis, Test Planning, Test Design, Test Execution, Defect Reporting, and Closure.

2. Model-Based Testing (MBT):

   • Model-Based Testing is an approach to software testing where test cases are derived from a model that describes the functional aspects of the system under test. This model can be graphical or textual and serves as a blueprint for designing test cases. It helps in automating the testing process and ensures test coverage based on the model.

3. Model-Based STLC:

   • Combining Model-Based Testing with the Software Testing Life Cycle means incorporating models into each phase of the testing process. This involves creating models to represent requirements, designing tests based on these models, and executing tests accordingly.

Here is a simplified breakdown of how Model-Based Testing can be integrated into the STLC:

• Requirements Analysis: Develop models representing system behavior based on requirements.

• Test Planning: Plan testing activities based on the models, identifying test scenarios and defining test objectives.

• Test Design: Derive test cases directly from the models, ensuring that they cover the specified requirements.

• Test Execution: Execute tests based on the designed test cases, either manually or through automated testing tools.

• Defect Reporting: Report any discrepancies between expected and actual results, and track them through resolution.

• Closure: Evaluate the testing process and deliverables, and prepare for project closure.

By incorporating models at each stage, Model-Based STLC aims to improve efficiency, coverage, and the overall effectiveness of the testing process.

Keep in mind that the actual implementation and tools used for Model-Based Testing can vary based on the specific needs and characteristics of the project or organization.
