Code test case
Verify that the logging application block can log the same message to multiple categories.
Verify that the application block logs messages to the trace listeners in a thread safe
manner.
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 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 Logging
Application Block.
Table 3: Logging Application Block Design Verification
Design test case Implemented? Feature that implements design
Verify that the application
block can be extended with
custom trace listeners, custom
formatters, and custom
filters.
Yes
The CustomTraceListener class and the
TraceListener class allow users to create
custom trace listeners.
The ILogFormatter interface and the LogFormatter
class allow users to create custom
formatters.
The ILogFilter interface and the LogFilter
class allow users to create custom filters.
Verify that the application
block uses a simple façade to
log messages.
Verify that there is a consistent
approach to creating
trace listeners, formatters,
and filters.
Verify that the application block
can retrieve configuration data
from different sources, such
as an application configuration
file, a database, or from
memory.
Yes
Yes
Yes
The Logger class is a façade that provides
simple methods to log messages.
The TraceListenerCustomFactory class creates
trace listener objects. The LogFormatterCustomFactory
class creates formatter
objects. The LogFilterCustomFactory class
creates filter objects.
The LogWriterFactory class has a constructor
that accepts a configuration source as an
input parameter.
