Clear property values in the DataSink teststep

Hi All,

I have a data-driven test setup. After each iteration I would like to clear the property values in DataSink test step.

I am using the below code and is not complete.

testRunner.testCase.getTestStepByName("DataSink").clearPropertyValues()

I would greeatly appreciate if you could help me with the code to clear the values of all the properties in datasink.

Thank you :-)
