How do I check “no exception occurred” in my MSTest unit test?

Question

I\'m writing a unit test for this one method which returns \"void\". I would like to have one case that the test passes when there is no exception thrown. How do I write t

This helper class scratched my itch with MSTest. Maybe it can scratch yours also.

[TestMethod]
public void ScheduleItsIneligibilityJob_HasValid_CronSchedule()
{
    // Arrange
    var factory = new StdSchedulerFactory();
    IScheduler scheduler = factory.GetScheduler();

    // Assert
    AssertEx.NoExceptionThrown(() =>
        // Act
        _service.ScheduleJob(scheduler)
    );
}

public sealed class AssertEx
{
    public static void NoExceptionThrown(Action a) where T:Exception
    {
        try
        {
            a();
        }
        catch (T)
        {
            Assert.Fail("Expected no {0} to be thrown", typeof(T).Name);
        }
    }
}
