Developers create unit tests to automate the testing of an isolated unit (method or property) in an application. A good unit test should not require configuration; it should be atomic in nature; it should test a common application state; and it should test all method conditions, including errors, null values, and boundary checks. You can verify the percentage of code that your unit tests cover. You should target at least 70 percent coverage for your unit tests. Integration, load, stress, and performance testing are all black box tests performed by the test team. Developers need to be aware of how these tests should be performed in order to provide feedback to the test team relative to testing their code. Integration tests verify that components work together to create a complete solution. Load tests are used to verify the application s performance under load. You can leverage load tests to stress test and performance test your application.

It is possible to determine a Windows mobile device ID only after synchronization has occurred. This is achieved by querying the device user s mailbox using Exchange Management Shell. It is possible to limit a user s ability to sync devices to specific device ID. Direct Push uses an extended HTTPS request to keep a connection to a Client Access server. If there is a change in the mailbox, such as a contact list being updated, a new appointment, or new messages, the request is responded to, and the device initiates synchronization. Once synchronization is complete, a new HTTPS request is issued. Remote wipe allows an administrator to remove all user data from a device, restoring it to its factory defaults. Remote wipe is used to ensure that sensitive data is not accessible to third parties in the event that the device is lost or stolen. The IMAP4 and POP3 services are not enabled by default on Client Access servers. It is possible to restrict individual users from using either protocol. It is also possible to use Exchange Management Shell commands to alter the ports and IP addresses that the protocols listen on and to adjust connection limits and time-out settings.

You can use the following questions to test your knowledge of the information in Lesson 2, Managing Security Settings. The questions are also available on the companion CD if you prefer to review them in electronic form.

Configuring VPN site-to-site networks will be discussed in detail in 10, Configuring Virtual Private Networks for Remote Clients and Networks.

After a lease has been created, modifying the properties of the lease has no effect on the lease. The lease duration can be renewed by a sponsor object or by manually call ing the Renew method of the ILease interface from a client application as shown in the following code example.
