With this type of testing you compare how selected pages on a hostname will be served after config changes are applied with how they are delivered currently to real end users.
Results show the differences between the two behaviors, helping you predict what to expect after activating your configuration changes.
To test a configuration change, run one or more test definitions with at least one test case. Test Center makes comparisons based on your test definitions, test cases, and run settings. For more details on the steps involved, read the corresponding topic.
