Finally block is executed only on Debug mode

Question is taken from here: SO - Timeout in c# tests

I created a simple unit test like this:

[Timeout(1000)][TestMethod]
public void TestMethod1()
{
    try
    {
        System.Threading.Thread.Sleep(2000);
    }
    finally
    {
        Console.WriteLine("Executed");
    }
}

When I run the test, the finally block is not executed. But when I debug it, it does. Why is this happening?

Timeout is disabled during debugging, so you get to see Console.WriteLine() output.

But i still think finally is executed in vs2010. If you try to show a message box System.Windows.Forms.MessageBox.Show("finally") you should be able to see it pops up.

Console.WriteLine output is lost after timeout in vs2010.

The Timeout attribute simply does not apply to Debugging sessions.

You specify the test timeout at 1000 ms, while your method sleeps for 2000 ms. This results in your test method being prematurely force-closed by the test framework, so it doesn't leave the Sleep call and doesn't have time to reach finally block. Debugging probably disables the timeout attribute.
