The Assert functoid (.jpeg "Assert functoid")
) enables you to test your assumptions about conditions in your map. For example, if you perform some calculations to determine an additional discount on product purchases, you might assert that the additional discount be no more than $100 by using a logical functoid (Greater Than or Less Than).
Input
Parameter 1: A Boolean value, generally from the output of some other Logical functoid or from a variable Boolean field in the input instance message.
Parameter 2: Text to use when throwing an exception if Parameter 1 is False. This should be a descriptive statement that can be used to locate the source of the failed assertion.
Parameter 3: Text to return if the Parameter 1 is True.
Output
Output 1: The text value of Parameter 3 if Parameter 1 is True; otherwise, the functoid throws an exception.
Remarks
The Assert functoid only fires in development builds or when the Generate Debugging Informationproperty in the project build settings is set to True. When your BizTalk Server application is compiled for deployment and the Generate Debugging Information property is set to False (the default), assertions are ignored.
Note
Balance the need for Assert functoid processing in production builds with the additional overhead that may be required to process them.
