Yats – Supporting Cancel in a Test Case

Some test cases may take a long time and should provide a Cancel option. Cancel is implemented by implementing the ICancellable interface (part of Yats Native test repository manager).

The following example is a Delay test that simply sleeps for a specified time or stops immediately when canceled:

 public class DelayTest : IYatsTestCase, ICancellable
  {
         TimeSpan delay;
         public TimeSpan Delay
         {
             get {return delay;}
             set {delay = value;}
         }

         public DelayTest ()
         {
         }

         #region IYatsTestCase Members
protected AutoResetEvent waitFor = new AutoResetEvent( false );
         public ITestResult Execute()
         {
             if(waitFor.WaitOne( delay ) == false)
             {
                 return new TestResult( ResultEnum.PASS );
             }
             else
             {
                 return new TestResult( ResultEnum.CANCELED );
             }
         }

         #endregion

         #region ICancellable Members

         public void Cancel()
         {
             waitFor.Set( );
         }

         #endregion
     }
