Testing the Cryptography
Application Block
This chapter explains how functional testing techniques were used to test the
Cryptography Application Block. If you have modified or extended the Cryptography
Application Block, you can use the same techniques and adapt the chapter’s
templates and checklists to test your own work.
Requirements for the Cryptography Application Block
The Cryptography Application Block has the following requirements:
●
●
●
●
●
●
●
The application block should support common cryptography operations.
The application block should be extensible.
The symmetric encryption providers and the hash providers should be
configurable.
The application block should support configurable instrumentation, including
WMI (Windows Management Instrumentation), performance counters, and event
logs.
The application block should be able to read configuration information from any
configuration source, such as an XML file or a database.
The symmetric key that encrypts the data should be cached in memory in an
encrypted form.
The application block should work with desktop applications and with Web
applications.
These requirements must be incorporated into the design and implemented by the
code.
Selecting the Test Cases
The first step in a functional review is to make sure that the design and the code
support the requirements. You do this by deciding the test cases that the design and
code must satisfy. Table 1 lists the test cases that the application block’s design must
satisfy.
