Description copied from class: ContentItemsSource

Resets the input for this content source, so that the test would behave as if it was just started, input-wise.

NOTE: the default implementation resets the number of bytes and items generated since the last reset, so it's important to call super.resetInputs in case you override this method.

Overrides:

resetInputs in class ContentItemsSource

Throws:

IOException
