User Interface Testing
What is User Interface Testing?
User interface testing, a testing technique used to identify the presence of defects is a product/software under test by using Graphical user interface [GUI].
GUI Testing - Characteristics:
GUI is a hierarchical, graphical front end to the application, contains graphical objects with a set of properties.
During execution, the values of the properties of each objects of a GUI define the GUI state.
It has capabilities to exercise GUI events like key press/mouse click.
Able to provide inputs to the GUI Objects.
To check the GUI representations to see if they are consistent with the expected ones.
It strongly depends on the used technology.
GUI Testing - Approaches:
Manual Based - Based on the domain and application knowledge of the tester.
Capture and Replay - Based on capture and replay of user actions.
Model-based testing - Based on the execution of user sessions based on a GUI model. Various GUI models are briefly discussed below.
Model Based Testing - In Brief:
Event-based model - Based on all events of the GUI need to be executed at least once.
State-based model - "all states" of the GUI are to be exercised at least once.
Domain model - Based on the application domain and its functionality.
GUI Testing Checklist:
Check Screen Validations
Verify All Navigations
Check usability Conditions
Verify Data Integrity
Verify the object states
Verify the date Field and Numeric Field Formats
