WHITE BOX TEST PLAN

The white box test plan consists of the invocation coverage plan, the branch coverage plan, the loop coverage plan, and the condition coverage plan. Basically, this plan test to see that every line of code in our system is executed. The individual coverage plans are as follows:

For the Control Panel:

Invocation Coverage Plan

Every method involved in the Look-and-Feel will write out to a test window which will display strings consisting of what method and what parameters were passed to it.

Example: If we create a Button, a call will be placed inside the constructor, and update, along with other methods. When these methods are invoked, relevant strings are written to the test window.

We then view the test window to see if all the necessary calls were made.

Branch Coverage Plan

Exhaustive user input testing. By this we mean that every possible combination of components and their properties must be selected and displayed in a window. With 17 components, each having at most three property settings, we are looking at a very large list of possible cases.

Loop Coverage Plan

The loops within the control panel are fully exercised when a component_list is updated and when a component is removed from a component_list.

Condition Coverage Plan

Again, by the nature of our program, conditional branching situations are brought up by user selected combinations within the Graphical User Interface.

Example: If the saved data file exists (yes/no) then run the applet with the file OR run the applet without the file.

Example: If the property does not exist, add it by creating a dummy M_Class component which will add a test property and change it, OR create a new instance of a M_Class which already exists.

Example: If the M_Class name does not exist on the Component List then a dummy M_Class is added to the Component List and a new list is created for this specific component OR a new instance of a component is placed at the tail of the linked list of the same type.

Example: If all the Instances of M_Classes are removed from a type of component list then the component is removed from the Component List.
