Keep an Active Session Running on the Execution Server
Scheduling involves running Telerik Test Studio tests on an Execution Server. However, any test that requires moving the mouse or sending keystrokes requires an unlocked desktop. Telerik tests are not the only ones affected by this Windows limitation. This is a general problem with any tool that performs UI testing.
Telerik tests running against HTML-based web applications (ASP .NET and others) frequently can work on a locked machine because most test steps don't use the mouse or keyboard. Instead they are able to inject events (like a Click or Select) directly into the DOM structure of the page. Unfortunately, when performing Silverlight or WPF testing, these events cannot be injected in the same way. We have to simulate system-wide mouse moves and mouse clicks instead.
Here is one possible solution to this challenge:
- Prepare three machines, virtual or physical. One of these is your intended execution server. Let's call the three machines A, B and C. Let's say B is the intended Execution Server.
- Start a Remote Desktop Connection on machine C and use it to log into A.
- Once logged in, start a Remote Desktop Connection on A and use it to connect to B.
- Once logged into B, remove the Remote Desktop Connection between A and C.
A Remote Desktop Connection remains open between A and B. This causes B to keep an active session. This allows you to use the machine as an Execution Server without human intervention.
- This is a stable solution based on how Windows treats remote sessions, and works on Windows Server 2003.
- This might not be as easy to implement on Windows Server 2008 & 7, depending on your company's security policy.
- Check with your System Administrator if you suspect security limitations are preventing you from implementing this approach.
- If you are using the Windows Task Scheduler to create a task for ArtOfTest.Runner, you must select Run only when user is logged on in the scheduled task's properties:
