Creating the Application Test Script
As long as you’re willing to make the required visibility changes to your application, you can use 
IronPython to test it. Creating a test project for an application works precisely the same as creating 
a test project for a DLL. Here’s the short list of changes you must perform:
1.
Change the build output location for both the Debug and Release builds to the solution folder.
2.
Add 
IPY.EXE
as an existing project to your solution.
3.
Set the ipy project as the startup project so that the IDE executes it instead of the Windows 
Forms application.
4.
Configure the ipy project to start your script and to use the appropriate working directory.
5.
Add a new IronPython script to the solution folder.
This test script uses the three functions described in Listing 18-2 to provide output. It also adds the 
following two output functions:
# Verify the type. 
def CheckType(Object, Type):
if Object.GetType().__str__() == Type:
print ‘Test Passed’
else:
print ‘Test Failed’
# Show initial values. 
def ShowInit(Value1, Value2):
print ‘Value1: ‘, Value1
print ‘Value2: ‘, Value2
The 
CheckType()
function compares the type of an object you create against an expected type. If 
the type is incorrect, then it displays a failed message. You can use this function when creating a 
form or other object that could fail for any number of reasons.
The 
ShowInit()
function displays the initial values for a binary operation or perhaps just two values 
used for some other task. You could probably create a version of the function that accepts any number 
of arguments in the form of an array. The point is that you can create some specialized functions to 
display data for a particular test and then find that you can use it for other purposes later.
As previously mentioned, this test script also uses the three functions found in Listing 18-2. 
Listing 18-4 shows the actual test script for this application. It doesn’t provide a complete test but 
does provide enough information that you could easily complete it if you wanted.
