Figure 8.5 We design policies for execution within runtime service governance
technology.
Runtime governance technology typically features the ability to test policies;
in some cases, specialized testing software is needed. However, policies
can be tested during runtime as they execute along with the services on a test
platform. The approach and technology you leverage will depend on your
requirements.
To test policies effectively, you should create a test plan that outlines how
the policy should be tested. Things typically included in a test plan are the definitions
of test data, the process of testing the policy, and what defines a policy
that is ready for acceptance. The bad news is that you have to create the test
plan. The good news is that test plans are typically pretty short for each policy.
Deployment of the policy means moving it into production within the
runtime service governance technology or on another platform for executing
the policy. Issues to consider for deployment include making sure the platform
for policy execution is working as per the requirements. This includes
having features in the repository to track the policies, or logging features (see
Figure 8.5).
