ETA User Interface Prototype and Walkthrough

Appendix: Screen Shots of Prototype

[prev]

1) Main Screen at Startup

2) Main Screen after loading and instantiating a class, and creating some parameter objects

3) Main Screen after class loaded/instantiated, viewing 'Returned Objects' tab after calling several functions that return objects

4) Object Pool - Parameters Object Tab showing parameter objects of different types. The display of objects will become scrollable when needed.

5) Object Pool - Returned Objects tab showing objects of different types. The display of objects will become scrollable when needed.

6) Methods Panel displaying methods with different modifiers, return types, and parameters. Modifier symbols will be implemented as 32x32 icons in final version. The display of methods will become scrollable when needed.

7) Fields panel displaying fields of different data types. Modifier symbols will be implemented as 32x32 icons in final version. Some field values are read-only because they are final. In the case of a final field that is an object, the read-only object inspector will be displayed instead of the normal object inspector (see #13). The display of fields will become scrollable when needed.

8) Status Panel - Output tab
The Output tab displays all of the output and error messages sent to System.out and System.err by the class being tested

Status Panel - Messages tab
The Messages tab displays error messages from the ETA to the user after the user has done something bad, like trying to enter a String as a value for an int in the Object Pool

Status Panel - Session Log tab
The Session Log tab displays a time-stamped log of all of the User's actions

9) 'Open Class' modal dialog with a class name input by user

Dialog appears when user selects 'File | Open Class...' menu item

10) 'New Test Data Item' modal dialogs
Dialog appears when user clicks 'New Test Data Item...' button in 'Test Data Items' tab or selects 'Test | New Test Data Item...' menu item

Series of Dialogs for creating a new primitive test data item

Series of dialogs for creating a new non-primitive test data item
In the third dialog, the OK button is disabled until the parameter combo boxes have been filled out for the selected constructor. Parameter combo boxes for constructors other than the selected one are disabled.

11) 'Instantiate Class' modal dialogs
Dialog appears when user selects 'Test | Instantiate Main Test Class...' menu item
The OK button is disabled until the parameter combo boxes have been filled out for the selected constructor. Parameter combo boxes for constructors other than the selected one are disabled.

12) 'Object Inspector' modal dialogs (2 variations)
Dialog appears when user clicks on an 'Inspect...' button in the 'Test Data Items' tab of the object pool. These 'Inspect...' buttons appear only when the object whose value you want to inspect is derived from java.lang.Object.

Variation 1: Object being inspected can be modified by the user (ie, when inspecting test data item values). Data is layed out like the Fields panel. The display of fields will become scrollable when the number of fields in the object is greater than 10.
Final fields are have read only values.
Primitive fields can be changed by selecting a different test data item in the combo box or typing in a new value.
Fields of types derived from 'Object' can be changed in the same way, but to view them, a user has to click on its Name button (which adds the field in question to the object pool), closes the current Object Inspector, looks for the recently added Object in the 'Test Data Items' tab, and brings up a new Object Inspector on the object that was just added.

Variation 2: Object being inspected can't be modified by the user (ie, when viewing returned object values). Data is layed out like the Fields panel. The display of fields will become scrollable when the number of fields in the object is greater than 10.
