Parameters

Test-CsGroupIM is an example of a Lync Server 2010 synthetic transaction. Synthetic transactions are used in Lync Server to verify that users are able to successfully complete common tasks such as logging on to the system, exchanging instant messages, or making calls to a phone located on the public switched telephone network (PSTN). These tests can be conducted manually by an administrator, or they can be automatically run by an application such as Microsoft System Center Operations Manager (formerly Microsoft Operations Manager).

Synthetic transactions are typically conducted in two different ways. Many administrators will use the CsHealthMonitoringConfiguration cmdlets to set up test users for each of their Registrar pools. These test users are a pair of users who have been preconfigured for use with synthetic transactions. (Typically these are test accounts and not accounts that belong to actual users.) With test users configured for a pool, administrators can simply run a synthetic transaction against that pool without having to specify the identities of (and supply the credentials for) the user accounts involved in the test.

Alternatively, administrators can run a synthetic transaction using actual user accounts. For example, if two users are unable to exchange instant messages, an administrator could run a synthetic transaction using the two user accounts in question (as opposed to a pair of test accounts), and then try to diagnose and resolve the problem. If you decide to conduct a synthetic transaction using actual user accounts, you will need to supply credentials for each user.

The Test-CsGroupIM cmdlet enables you to verify that users in your organization can conduct conferences. Test-CsGroupIM requires two user accounts in order to conduct its tests. If you have set up test users for the pool where the test is to be conducted, then you do not need to specify these accounts; instead, Test-CsGroupIM will automatically use the test accounts assigned to pool. (For details, see the New-CsHealthMonitoringConfiguration help topic.) Alternatively, you can conduct the test using accounts other than the ones assigned to the Registrar. This allows you run tests even if you have not configured test users for the pool. It also allows you to test the ability of two specific users to conduct a conference. If you choose to use this approach, you will need to provide the user name and password for both users.

When you run Test-CsGroupIM, the cmdlet attempts to sign both test users on to Lync Server. If successful, Test-CsGroupIM creates a new conference using the first test user, then invites the second user to join the conference. After an exchange of messages, both users are then disconnected from the system. All of this happens without any user interaction, and without affecting any actual users. For example, suppose the test account sip:kenmyer@litwareinc.com corresponds to a real user with a real Lync Server account. In that case, the test will be conducted without any disruption to the real Ken Myer. For example, even when the Ken Myer test account logs off from the system, Ken Myer the person will remain logged on. Likewise, the real Ken Myer will not receive an invitation to join the conference. That invitation will be sent to, and accepted by, the test account.

Adding the Verbose parameter enables you to get a detailed account of all the actions taken by Test-CsGroupIM in order to complete its test.

Who can run this cmdlet: To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "Test-CsGroupIM"}

None. Test-CsGroupIM does not accept pipelined input.

Test-CsGroupIM returns an instance of the Microsoft.Rtc.SyntheticTransactions.TaskOutput object.

-------------------------- Example 1 --------------------------

	Copy Code
Test-CsGroupIm -TargetFqdn atl-cs-001.litwareinc.com

The preceding example checks to see if a pair of preconfigured test users can log on to the pool atl-cs-001.litwareinc.com and participate in an IM conference. This command will work only if test users have been defined for the pool atl-cs-001.litwareinc.com. If they have, then the command will determine whether the two test users can log on to the system, and then check to see if these users can participate in an instant messaging conference.

If test users have not been defined, then the command will fail because it will not know which users to employ when doing the test. If you have not defined test users for a pool, then you must include the SenderSipAddress and ReceiverSipAddress parameters and the corresponding credentials for the users involved in the instant messaging session. Test-CsGroupIM will then conduct its checks using the two specified users.

-------------------------- Example 2 --------------------------

	Copy Code
$cred1 = Get-Credential "litwareinc\pilar" $cred2 = Get-Credential "litwareinc\kenmyer" Test-CsGroupIm -TargetFqdn atl-cs-001.litwareinc.com -SenderSipAddress "sip:pilar@litwareinc.com" -SenderCredential $cred1 -ReceiverSipAddress "sip:kenmyer@litwareinc.com" -ReceiverCredential $cred2

The commands shown in Example 2 test the ability of a pair of users (litwareinc\pilar and litwareinc\kenmyer) to log on to Lync Server, and then participate in an instant messaging conference. To do this, the first command in the example uses the Get-Credential cmdlet to create a Windows PowerShell credential object containing the name and password of the user Pilar Ackerman. (Because the logon name, litwareinc\pilar, has been included as a parameter, the resulting Windows PowerShell Credential Request dialog box only requires the administrator to enter the password for the Pilar Ackerman account.) The resulting credential object is then stored in a variable named $cred1. The second command does the same thing, this time returning a credential object for the Ken Myer account.

With the two credential objects in hand, the third command in the example determines whether or not the two users can log on to Lync Server and then participate in an instant messaging conference. To carry out this task, Test-CsGroupIM is called, along with the following parameters: TargetFqdn (the FQDN of the Registrar pool); SenderSipAddress (the SIP address the first user); SenderCredential (the user credentials for the first user); ReceiverSipAddress (the SIP address for the second user); and ReceiverCredential (user credentials for the second user).
