OpenTap.ScalarResultSink< T > Class Template Reference

ResultSink that will provide the first result from a given result column published by a given TestStep. When SourceTestStep is inside a loop step, only results from the last iteration of SourceTestStep is accessible. More...

	ScalarResultSink (ITestStep listeningStep)

T	GetResult (CancellationToken ct)
	Called by TestSteps when the result is needed. Blocks until a result is available.
bool	TryGetResult (out T result)
	Called by TestSteps when the result is needed. Returns true if a result is available.
void	OnTestStepRunStart (TestStepRun run)
	Resets result collection when a new run of the SourceTestStep is started.
void	OnTestStepRunCompleted (TestStepRun run)
	Called when a TestStep is completed.
void	OnResultPublished (TestStepRun stepRun, ResultTable result)
	Called by OpenTAP when the source TestStep publishes results. This is happening in a background thread.
void	OnTestPlanRunStart (TestPlanRun run)
	Initializes this instance.
void	OnTestPlanRunCompleted (TestPlanRun run)
	Cleans up after this instance

Properties

	The ID of the source TestStep that we are interested in results from.
string	ResultColumnName [getset]
	The name of the result column to get the result from.

Constructor & Destructor Documentation

ScalarResultSink()

OpenTap.ScalarResultSink< T >.ScalarResultSink ( ITestStep  listeningStep )

inline

Creates an instance. This should probably be called from the constructor of the TestStep.

public class ListeningStepExample : TestStep
{
    public ITestStep SourceStep { get => Sink.SourceTestStep; set => Sink.SourceTestStep = value; }
    public ScalarResultSink<double> Sink { get; set; }
 
    public ListeningStepExample()
    {
        Sink = new ScalarResultSink<double>(this);
    }
 
    public override void Run()
    {
        log.Debug("Result was: {0}", Sink.GetResult(TapThread.Current.AbortToken));
    }
}

Parameters
