Code test case
Verify that the application block uses the Logging Application Block to log the exceptions.
Verify that the performance counters and the event log that are required by the application
block are installed during installation.
Verify that the application block requests or demands the appropriate code access
security permissions to access protected system resources and operations.
Verify that the application block follows exception management best practices.
Verify that the application block follows security best practices.
Verify that the application block follows globalization best practices.
Verify that the application block follows performance best practices.
Verifying the Test Cases
After you identify all the design test cases, you can verify that the design satisfies
them. Table 3 lists how each of the design test cases were verified for the Exception
Handling Application Block.

Verify that the exception handlers
and the exception formatters
are extensible.
Verify that there is a consistent
approach to creating exception
policies, exception handlers,
and exception formatters.
Verify that there is a façade
that mediates between the
client code and the application
block to handle exceptions.
Verify that the application block
generates a new GUID named
the HandlingInstanceID for
every exception that is
handled.
Verify that the ability to create
the application block’s domain
objects from the configuration
data follows the Dependency
Injection pattern.

The IExceptionHandler interface allows users to
implement a configurable exception handler. The
ExceptionFormatter class allows users to extend
an exception formatter.
The ExceptionHandlerCustomFactory class is the
factory that creates the objects that implement the
IExceptionHandler interface.
The ExceptionPolicy class is a façade that acts
as the interface between the client code and the
application block.
The ExceptionPolicyEntry.Handle method generates
a new GUID named the HandlingInstanceID
and passes that GUID to the exception handlers.
The ExceptionPolicyFactory class derives from the
LocatorNameTypeFactoryBase generic type, which
takes the configuration source as input, creates
the domain object, and injects the relevant configuration
data into the domain object.
