Event Handler Sub-layer

Input Sub-layer

Database Sub-layer

Manager Sub-layer

Analyzer Sub-layer

Check Sub-layer

Browser Sub-layer

Question: Which browser do you prefer? http://one7.files.wordpress.com/2010/06/browsers.jpg 7/7/11

Testing for I/O Layer 1) Can the input sub-layer process the input from the external devices within a reasonable amount of time? 2) Can the database sub-layer add, update, delete data from the database? 3) Does the input and database sub-layers sent data to the appropriate location? 4) Does the input simplify the data correctly?

Testing Logic Layer 1) Can the Check Sub-Layer find and report errors? 2) Does the Event Handler send data to the function of the assigned Destination? 3) Do all the sub-layers communicate with the Event Handler correctly? 4) Does the Analyzer sub-layer launch an attention getter event when the user isn’t concentrated for a certain time period?

Testing Controls 1) Can the Browser Sub-Layer communicate with the browser? 2) Are the attention getters appearing on the screen for the designated time? 3) Can the Browser Sub-Layer turn off our program when the browser is closed?
