What is your application /Why do you need the application GUI – Graphical User Interface GUI Testing – Test the software with GUI The most of software are using GUI to interact with user, and GUI plays very important role in software Test Driven Design (TDD) is very popular

How to do GUI Testing Automation Reduce time to operate the software Create test case in easy way Use a great algorithm to generate test data Provide a convenient way to edit test-flow

Basic Concept Determine what to test Generate test input Generate expected output Execute test case and verify output Determine if the GUI was adequately test Performing regression testing

MVC Pattern ATAM Step 4 Identify Architectural Approaches Because of providing graphic interface, implementation with MVC pattern is required In order to add new edition way and views The most important parts of GUI Testing is core algorithm, and we should separate it from view

Layer Pattern By context diagram, whole GUI Testing architecture just likes layers Each layer’s output will be as next layer’s input

ATAM Step 5 Generate Quality Attribute Utility Tree Attribute Refinement Scenario Reliability Detect incorrect GUI components … Modifiability Test Driven Support other GUI library Performance Do test oracle Test Case Generation

ATAM Step 6 Analyze Architectural Approaches Scenario #: M3 Scenario: Add edition of test case ways and views, and should be done in a week Attribute(s) Modifiability Environment Design Time Stimulus Change tree-view to diagram-view Response Modification is made without effecting model Architecture decisions Sensitivity Tradeoff Risk Nonrisk MVC Pattern S1 Reasoning If want to generate test case by FSM ways, add diagram-view into editor is quite important. Architecture Diagram Tree view Diagram view Editor

Analyze Architectural Approaches Sensitivity S1: MVC pattern is a sensitivity point to modifiability. S2: Update the newest hardware is a sensitivity point to performance.
