Testing the Application Block 27
After the code is implemented, you can review it to see if it satisfies its test cases.
Table 4 lists the results of a code review for the Caching Application Block.
Table 4: Caching Application Block Code Verification
Code test case Implemented? Feature that is implemented
Verify that the application
block creates only one
CacheManager instance for
the given instance name.
Verify that assembler
classes that implement the
IAssembler interface create
the backing store providers
and the encryption providers,
and inject the configuration
object values into
those domain objects.
Yes
Yes
The CacheManagerFactory class creates a
CacheManager instance. The CacheManager-
Factory class derives from the LocatorName-
TypeFactoryBase class. This class creates only
one instance for a given instance name.
The following code demonstrates how the
DataBackingStoreAssembler class, which
implements the IAssembler interface, creates a
backing store.
public class DataBackingStoreAssembler
: IAssembler
{
public IBackingStore Assemble(…)
{
IBackingStore createdObjet = new Data-
BackingStore(…);
return createdObjet;
}
}
The following code demonstrates how the SymmetricStorageEncryptionProviderAssembler,
which implements the IAssembler interface,
creates a symmetric encryption provider.
public class SymmetricStorageEncryptionProviderAssembler
: IAssembler
{
public IStorageEncryptionProvider Assemble(…)
{
IStorageEncryptionProvider createdObject
= new SymmetricStorageEncryptionPr
ovider(symmetricCrytoProvider);
return createdObject;
}
}
