Custom Component And Unit Testing

Hello.


I want to test my custom component with unit tests and i thought i must only initilize the component to play around with it. But when i calling the ProviderComponentProperties method and there the RemoveAllInputsOutputsAndCustomProperties method a NullReference exception is thrown. After debugging the test i had seen that the ComponentMetaData of the component is null. Is there a way to initilize the ComponentMetaData?

The Code of the Component looks like this:




Code Block
[DtsPipelineComponent(
DisplayName = "TestSourceAdapter",
ComponentType = ComponentType.SourceAdapter,
IconResource = "TestSourceAdapter.TestSourceAdapter.ico"
)]
public class TestSourceAdapter: PipelineComponent
{

public override void ProvideComponentProperties()
{

RemoveAllInputsOutputsAndCustomProperties();

IDTSOutput90 output = ComponentMetaData.OutputCollection.New();
output.Name = "TestSourceAdapter";


ComponentMetaData.OutputCollection

["TestSourceAdapter"].ExternalMetadataColumnCollection.IsUsed = true;

ComponentMetaData.ValidateExternalMetadata = false;
ComponentMetaData.UsesDispositions = true;
ComponentMetaData.Name = "TestSourceAdapter";
ComponentMetaData.Description = "TestSourceAdapter";


ReinitializeMetaData();
}


...
}




And in test i call only this




Code Block
TestSourceAdapter testAdapter = new TestSourceAdapter();
_testAdapter.ProvideComponentProperties();





i hope anyone can help
