GUI – Graphical User InterfaceGUI 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

Sample

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

Sample

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

Sample

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

Sample

By context diagram, whole GUI Testing architecture just likes layers

Each layer’s output will be as next layer’s input

MVC Pattern S1

Reasoning If want to generate test case by FSM ways, add diagram-view into editor is quite important.

Sensitivity S1: MVC pattern is a sensitivity point to

modifiability. S2: Update the newest hardware is a

sensitivity point to performance.
