TestNodeCollectionSelection

class TestNodeCollectionSelection(testContext: TestContext, selector: TestNodeSelector)

Lazy representation of a collection of test nodes with necessary logic to materialize on-demand.

Note: materializing the TestNodeSelection should result a collection of test node unless the assertDoesNotExist method is used.
