27. 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?

28. 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?

29. 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?
